-The Open On-Chip Debugger (openocd) aims to provide debugging, in-system programming\r
-and boundary-scan testing for embedded target devices. The targets are interfaced\r
-using JTAG (IEEE 1149.1) compliant hardware, but this may be extended to other\r
-connection types in the future.\r
-\r
-Openocd currently supports Wiggler (clones), FTDI FT2232 based JTAG interfaces, the\r
-Amontec JTAG Accelerator, and the Gateworks GW1602. It allows ARM7 (ARM7TDMI and ARM720t),\r
-ARM9 (ARM920t, ARM922t, ARM926ej--s, ARM966e--s), XScale (PXA25x, IXP42x) and\r
-Cortex-M3 (Luminary Stellaris LM3 and ST STM32) based cores to be debugged.\r
-\r
-Flash writing is supported for external CFI compatible flashes (Intel and AMD/Spansion\r
-command set) and several internal flashes (LPC2000, AT91SAM7, STR7x, STR9x, LM3\r
-and STM32x). Preliminary support for using the LPC3180's NAND flash controller is included.\r

-Openocd has been created by Dominic Rath as part of a diploma thesis written at the\r
-University of Applied Sciences Augsburg (@uref{http://www.fh-augsburg.de}).\r
-Others interested in improving the state of free and open debug and testing technology\r
-are welcome to participate.\r
-\r
-Other developers have contributed support for additional targets and flashes as well\r
-as numerous bugfixes and enhancements. See the AUTHORS file for regular contributors. \r

-You can download the current SVN version with SVN client of your choice from the\r
-following repositories:\r
-\r
- (@uref{svn://svn.berlios.de/openocd/trunk})\r
-\r
-or\r
-\r
- (@uref{http://svn.berlios.de/svnroot/repos/openocd/trunk})\r
-\r
-Using the SVN command line client, you could use the following command to fetch the\r
-latest version (make sure there is no (non-svn) directory called "openocd" in the\r
-current directory):\r
-\r
-@smallexample\r
- svn checkout svn://svn.berlios.de/openocd/trunk\r
-@end smallexample\r
-\r
-Building the OpenOCD requires a recent version of the GNU autotools.\r
-On my build system, I'm using autoconf 2.13 and automake 1.9. For building on Windows,\r
-you have to use Cygwin. Make sure that your @env{PATH} environment variable contains no\r
-other locations with Unix utils (like UnxUtils) - these can't handle the Cygwin\r
-paths, resulting in obscure dependency errors (This is an observation I've gathered\r
-from the logs of one user - correct me if I'm wrong).\r
-\r
-You further need the appropriate driver files, if you want to build support for\r
-a FTDI FT2232 based interface:\r
-@itemize @bullet\r
-@item @b{ftdi2232} libftdi (@uref{http://www.intra2net.com/opensource/ftdi/})\r
-@item @b{ftd2xx} libftd2xx (@uref{http://www.ftdichip.com/Drivers/D2XX.htm})\r
-@item When using the Amontec JTAGkey, you have to get the drivers from the Amontec\r
-homepage (@uref{www.amontec.com}), as the JTAGkey uses a non-standard VID/PID. \r
-@end itemize\r
-\r
-Please note that the ftdi2232 variant (using libftdi) isn't supported under Cygwin.\r
-You have to use the ftd2xx variant (using FTDI's D2XX) on Cygwin.\r
-\r
-In general, the D2XX driver provides superior performance (several times as fast),\r
-but has the draw-back of being binary-only - though that isn't as worse, as it isn't\r
-a kernel module, only a user space library.\r
-\r
-To build OpenOCD (on both Linux and Cygwin), use the following commands:\r
-@smallexample\r
- ./bootstrap \r
-@end smallexample\r
-Bootstrap generates the configure script, and prepares building on your system.\r
-@smallexample\r
- ./configure \r
-@end smallexample\r
-Configure generates the Makefiles used to build OpenOCD\r
-@smallexample\r
- make \r
-@end smallexample\r
-Make builds the OpenOCD, and places the final executable in ./src/\r
-\r
-The configure script takes several options, specifying which JTAG interfaces\r
-should be included:\r
-\r
-@itemize @bullet\r
-@item\r
---enable-parport\r
-@item\r
---enable-parport_ppdev\r
-@item\r
---enable-amtjtagaccel\r
-@item\r
---enable-ft2232_ftd2xx\r
-@footnote{Using the latest D2XX drivers from FTDI and following their installation\r
-instructions, I had to use @option{--enable-ft2232_libftd2xx} for the OpenOCD to\r
-build properly}\r
-@item\r
---enable-ft2232_libftdi\r
-@item\r
---with-ftd2xx=/path/to/d2xx/\r
-@end itemize\r
-\r
-If you want to access the parallel port using the PPDEV interface you have to specify\r
-both the @option{--enable-parport} AND the @option{--enable-parport_ppdev} option since\r
-the @option{--enable-parport_ppdev} option actually is an option to the parport driver\r
-(see @uref{http://forum.sparkfun.com/viewtopic.php?t=3795} for more info).\r
-\r
-Cygwin users have to specify the location of the FTDI D2XX package. This should be an\r
-absolute path containing no spaces.\r
-\r
-Linux users should copy the various parts of the D2XX package to the appropriate\r
-locations, i.e. /usr/include, /usr/lib. \r

-The OpenOCD runs as a daemon, waiting for connections from clients (Telnet or GDB).\r
-Run with @option{--help} or @option{-h} to view the available command line arguments.\r
-\r
-It reads its configuration by default from the file openocd.cfg located in the current\r
-working directory. This may be overwritten with the @option{-f <configfile>} command line\r
-switch.\r
-\r
-To enable debug output (when reporting problems or working on OpenOCD itself), use\r
-the @option{-d} command line switch. This sets the debug_level to "3", outputting\r
-the most information, including debug messages. The default setting is "2", outputting\r
-only informational messages, warnings and errors. You can also change this setting\r
-from within a telnet or gdb session (@option{debug_level <n>}).\r
-\r
-You can redirect all output from the daemon to a file using the @option{-l <logfile>} switch.\r
-\r
-Search paths for config/script files can be added to openocd by using\r
-the @option{-s <search>} switch.\r

-@chapter Configuration\r
-@cindex configuration\r
-The Open On-Chip Debugger (OpenOCD) runs as a daemon, and reads it current configuration\r
-by default from the file openocd.cfg in the current directory. A different configuration\r
-file can be specified with the @option{-f <conf.file>} given at the openocd command line.\r
-\r
-The configuration file is used to specify on which ports the daemon listens for new\r
-connections, the JTAG interface used to connect to the target, the layout of the JTAG\r
-chain, the targets that should be debugged, and connected flashes.\r

-@item @b{reset_config} <@var{signals}> [@var{combination}] [@var{trst_type}] [@var{srst_type}]\r
-@cindex reset_config\r
-The configuration of the reset signals available on the JTAG interface AND the target.\r
-If the JTAG interface provides SRST, but the target doesn't connect that signal properly,\r
-then OpenOCD can't use it. <@var{signals}> can be @samp{none}, @samp{trst_only},\r
-@samp{srst_only} or @samp{trst_and_srst}.\r
-[@var{combination}] is an optional value specifying broken reset signal implementations.\r
-@samp{srst_pulls_trst} states that the testlogic is reset together with the reset of\r
-the system (e.g. Philips LPC2000, "broken" board layout), @samp{trst_pulls_srst} says\r
-that the system is reset together with the test logic (only hypothetical, I haven't\r
-seen hardware with such a bug, and can be worked around).\r
-\r
-The [@var{trst_type}] and [@var{srst_type}] parameters allow the driver type of the\r
-reset lines to be specified. Possible values are @samp{trst_push_pull} (default)\r
-and @samp{trst_open_drain} for the test reset signal, and @samp{srst_open_drain}\r
-(default) and @samp{srst_push_pull} for the system reset. These values only affect\r
-JTAG interfaces with support for different drivers, like the Amontec JTAGkey and JTAGAccelerator. \r
-\r
-@item @b{jtag_device} <@var{IR length}> <@var{IR capture}> <@var{IR mask}> <@var{IDCODE instruction}>\r
-@cindex jtag_device\r
-Describes the devices that form the JTAG daisy chain, with the first device being\r
-the one closest to TDO. The parameters are the length of the instruction register\r
-(4 for all ARM7/9s), the value captured during Capture-IR (0x1 for ARM7/9), and a mask\r
-of bits that should be validated when doing IR scans (all four bits (0xf) for ARM7/9).\r
-The IDCODE instruction will in future be used to query devices for their JTAG\r
-identification code. This line is the same for all ARM7 and ARM9 devices.\r
-Other devices, like CPLDs, require different parameters. An example configuration\r
-line for a Xilinx XC9500 CPLD would look like this:\r
-@smallexample\r
-jtag_device 8 0x01 0x0e3 0xfe\r
-@end smallexample\r
-The instruction register (IR) is 8 bits long, during Capture-IR 0x01 is loaded into\r
-the IR, but only bits 0-1 and 5-7 should be checked, the others (2-4) might vary.\r
-The IDCODE instruction is 0xfe.\r

-The Open On-Chip Debugger (OpenOCD) allows user interaction through a telnet interface\r
-(default: port 4444) and a GDB server (default: port 3333). The command line interpreter\r
-is available from both the telnet interface and a GDB session. To issue commands to the\r
-interpreter from within a GDB session, use the @option{monitor} command, e.g. use\r
-@option{monitor poll} to issue the @option{poll} command. All output is relayed through the\r
-GDB session.\r

-@chapter GDB and Openocd\r
-@cindex GDB and Openocd\r
-Openocd complies with the remote gdbserver protocol, and as such can be used\r
-to debug remote targets.\r
-\r
-@section Connecting to gdb\r
-@cindex Connecting to gdb\r
-A connection is typically started as follows:\r
-@smallexample\r
-target remote localhost:3333\r
-@end smallexample\r
-This would cause gdb to connect to the gdbserver on the local pc using port 3333.\r
-\r
-To see a list of available openocd commands type @option{monitor help} on the\r
-gdb commandline.\r
-\r
-Openocd supports the gdb @option{qSupported} packet, this enables information\r
-to be sent by the gdb server (openocd) to gdb. Typical information includes\r
-packet size and device memory map.\r
-\r
-Previous versions of openocd required the following gdb options to increase\r
-the packet size and speed up gdb communication.\r
-@smallexample\r
-set remote memory-write-packet-size 1024\r
-set remote memory-write-packet-size fixed\r
-set remote memory-read-packet-size 1024\r
-set remote memory-read-packet-size fixed\r
-@end smallexample\r
-This is now handled in the @option{qSupported} PacketSize.\r
-\r
-@section Programming using gdb\r
-@cindex Programming using gdb\r
-\r
-By default the target memory map is not sent to gdb, this can be enabled by\r
-the following openocd config option:\r
-@smallexample\r
-gdb_memory_map enable\r
-@end smallexample\r
-For this to function correctly a valid flash config must also be configured\r
-in openocd. For speed also configure a valid working area.\r
-\r
-Informing gdb of the memory map of the target will enable gdb to protect any\r
-flash area of the target and use hardware breakpoints by default. This means\r
-that the openocd option @option{arm7_9 force_hw_bkpts} is not required when\r
-using a memory map.\r
-\r
-To view the configured memory map in gdb, use the gdb command @option{info mem}\r
-All other unasigned addresses within gdb are treated as ram.\r
-\r
-If @option{gdb_flash_program enable} is also used, gdb will be able to\r
-program any flash memory using the vFlash interface.\r
-\r
-gdb will look at the target memory map when a load command is given, if any\r
-areas to be programmed lie within the target flash area the vFlash packets\r
-will be used.\r
-\r
-Incase the target needs configuring before gdb programming, a script can be executed.\r
-@smallexample\r
-target_script 0 gdb_program_config config.script\r
-@end smallexample\r
-\r
-To verify any flash programming the gdb command @option{compare-sections}\r
-can be used.\r

-@node FAQ\r
-@chapter FAQ\r
-@cindex faq\r
-@enumerate\r
-@item OpenOCD complains about a missing cygwin1.dll\r
-\r
-Make sure you have Cygwin installed, or at least a version of OpenOCD that\r
-claims to come with all the necessary dlls. When using Cygwin, try launching\r
-the OpenOCD from the Cygwin shell.\r
-\r
-@item I'm trying to set a breakpoint using GDB (or a frontend like Insight or\r
-Eclipse), but OpenOCD complains that "Info: arm7_9_common.c:213\r
-arm7_9_add_breakpoint(): sw breakpoint requested, but software breakpoints not enabled".\r
-\r
-GDB issues software breakpoints when a normal breakpoint is requested, or to implement\r
-source-line single-stepping. On ARMv4T systems, like ARM7TDMI, ARM720t or ARM920t,\r
-software breakpoints consume one of the two available hardware breakpoints,\r
-and are therefor disabled by default. If your code is running from RAM, you\r
-can enable software breakpoints with the @option{arm7_9 sw_bkpts enable} command. If\r
-your code resides in Flash, you can't use software breakpoints, but you can force\r
-OpenOCD to use hardware breakpoints instead: @option{arm7_9 force_hw_bkpts enable}.\r
-\r
-@item When erasing or writing LPC2000 on-chip flash, the operation fails sometimes\r
-and works sometimes fine.\r
-\r
-Make sure the core frequency specified in the @option{flash lpc2000} line matches the\r
-clock at the time you're programming the flash. If you've specified the crystal's\r
-frequency, make sure the PLL is disabled, if you've specified the full core speed\r
-(e.g. 60MHz), make sure the PLL is enabled.\r
-\r
-@item When debugging using an Amontec Chameleon in its JTAG Accelerator configuration,\r
-I keep getting "Error: amt_jtagaccel.c:184 amt_wait_scan_busy(): amt_jtagaccel timed\r
-out while waiting for end of scan, rtck was disabled".\r
-\r
-Make sure your PC's parallel port operates in EPP mode. You might have to try several\r
-settings in your PC Bios (ECP, EPP, and different versions of those).\r
-\r
-@item When debugging with the OpenOCD and GDB (plain GDB, Insight, or Eclipse),\r
-I get lots of "Error: arm7_9_common.c:1771 arm7_9_read_memory():\r
-memory read caused data abort". \r
-\r
-The errors are non-fatal, and are the result of GDB trying to trace stack frames\r
-beyond the last valid frame. It might be possible to prevent this by setting up\r
-a proper "initial" stack frame, if you happen to know what exactly has to\r
-be done, feel free to add this here.\r
-\r
-@item I get the following message in the OpenOCD console (or log file):\r
-"Warning: arm7_9_common.c:679 arm7_9_assert_reset(): srst resets test logic, too".\r
-\r
-This warning doesn't indicate any serious problem, as long as you don't want to\r
-debug your core right out of reset. Your .cfg file specified @option{jtag_reset\r
-trst_and_srst srst_pulls_trst} to tell the OpenOCD that either your board,\r
-your debugger or your target uC (e.g. LPC2000) can't assert the two reset signals\r
-independently. With this setup, it's not possible to halt the core right out of\r
-reset, everything else should work fine.\r
-\r
-@item When using OpenOCD in conjunction with Amontec JTAGkey and the Yagarto\r
-Toolchain (Eclipse, arm-elf-gcc, arm-elf-gdb), the debugging seems to be\r
-unstable. When single-stepping over large blocks of code, GDB and OpenOCD\r
-quit with an error message. Is there a stability issue with OpenOCD?\r
-\r
-No, this is not a stability issue concering OpenOCD. Most users have solved\r
-this issue by simply using a self-powered USB Hub, which they connect their\r
-Amontec JTAGkey to. Apparently, some computers do not provide a USB power\r
-supply stable enough for the Amontec JTAGkey to be operated.\r
-\r
-@item When using the Amontec JTAGkey, sometimes OpenOCD crashes with the\r
-following error messages: "Error: ft2232.c:201 ft2232_read(): FT_Read returned:\r
-4" and "Error: ft2232.c:365 ft2232_send_and_recv(): couldn't read from FT2232".\r
-What does that mean and what might be the reason for this?\r
-\r
-First of all, the reason might be the USB power supply. Try using a self-powered\r
-hub instead of a direct connection to your computer. Secondly, the error code 4\r
-corresponds to an FT_IO_ERROR, which means that the driver for the FTDI USB\r
-Chip ran into some sort of error - this points us to a USB problem.\r
-\r
-@item When using the Amontec JTAGkey, sometimes OpenOCD crashes with the following\r
-error message: "Error: gdb_server.c:101 gdb_get_char(): read: 10054".\r
-What does that mean and what might be the reason for this?\r
-\r
-Error code 10054 corresponds to WSAECONNRESET, which means that the debugger (GDB)\r
-has closed the connection to OpenOCD. This might be a GDB issue.\r
-\r
-@item In the configuration file in the section where flash device configurations\r
-are described, there is a parameter for specifying the clock frequency for\r
-LPC2000 internal flash devices (e.g.\r
-@option{flash bank lpc2000 0x0 0x40000 0 0 lpc2000_v1 0 14746 calc_checksum}),\r
-which must be sepcified in kilohertz. However, I do have a quartz crystal of a\r
-frequency that contains fractions of kilohertz (e.g. 14,745,600 Hz, i.e. 14,745.600 kHz).\r
-Is it possible to specify real numbers for the clock frequency?\r
-\r
-No. The clock frequency specified here must be given as an integral number.\r
-However, this clock frequency is used by the In-Application-Programming (IAP)\r
-routines of the LPC2000 family only, which seems to be very tolerant concerning\r
-the given clock frequency, so a slight difference between the specified clock\r
-frequency and the actual clock frequency will not cause any trouble.\r
-\r
-@item Do I have to keep a specific order for the commands in the configuration file?\r
-\r
-Well, yes and no. Commands can be given in arbitrary order, yet the devices\r
-listed for the JTAG scan chain must be given in the right order (jtag_device),\r
-with the device closest to the TDO-Pin being listed first. In general,\r
-whenever objects of the same type exist which require an index number, then\r
-these objects must be given in the right order (jtag_devices, targets and flash\r
-banks - a target references a jtag_device and a flash bank references a target).\r
-\r
-@item Sometimes my debugging session terminates with an error. When I look into the\r
-log file, I can see these error messages: Error: arm7_9_common.c:561\r
-arm7_9_execute_sys_speed(): timeout waiting for SYSCOMP\r

+
+The Open On-Chip Debugger (openocd) aims to provide debugging, in-system programming
+and boundary-scan testing for embedded target devices. The targets are interfaced
+using JTAG (IEEE 1149.1) compliant hardware, but this may be extended to other
+connection types in the future.
+
+Openocd currently supports Wiggler (clones), FTDI FT2232 based JTAG interfaces, the
+Amontec JTAG Accelerator, and the Gateworks GW1602. It allows ARM7 (ARM7TDMI and ARM720t),
+ARM9 (ARM920t, ARM922t, ARM926ej--s, ARM966e--s), XScale (PXA25x, IXP42x) and
+Cortex-M3 (Luminary Stellaris LM3 and ST STM32) based cores to be debugged.
+
+Flash writing is supported for external CFI compatible flashes (Intel and AMD/Spansion
+command set) and several internal flashes (LPC2000, AT91SAM7, STR7x, STR9x, LM3
+and STM32x). Preliminary support for using the LPC3180's NAND flash controller is included.
+
+@node Developers
+@chapter Developers
+@cindex developers
+
+Openocd has been created by Dominic Rath as part of a diploma thesis written at the
+University of Applied Sciences Augsburg (@uref{http://www.fh-augsburg.de}).
+Others interested in improving the state of free and open debug and testing technology
+are welcome to participate.
+
+Other developers have contributed support for additional targets and flashes as well
+as numerous bugfixes and enhancements. See the AUTHORS file for regular contributors.

+You can download the current SVN version with SVN client of your choice from the
+following repositories:
+
+ (@uref{svn://svn.berlios.de/openocd/trunk})
+
+or
+
+ (@uref{http://svn.berlios.de/svnroot/repos/openocd/trunk})
+
+Using the SVN command line client, you could use the following command to fetch the
+latest version (make sure there is no (non-svn) directory called "openocd" in the
+current directory):
+
+@smallexample
+ svn checkout svn://svn.berlios.de/openocd/trunk
+@end smallexample
+
+Building the OpenOCD requires a recent version of the GNU autotools.
+On my build system, I'm using autoconf 2.13 and automake 1.9. For building on Windows,
+you have to use Cygwin. Make sure that your @env{PATH} environment variable contains no
+other locations with Unix utils (like UnxUtils) - these can't handle the Cygwin
+paths, resulting in obscure dependency errors (This is an observation I've gathered
+from the logs of one user - correct me if I'm wrong).
+
+You further need the appropriate driver files, if you want to build support for
+a FTDI FT2232 based interface:
+@itemize @bullet
+@item @b{ftdi2232} libftdi (@uref{http://www.intra2net.com/opensource/ftdi/})
+@item @b{ftd2xx} libftd2xx (@uref{http://www.ftdichip.com/Drivers/D2XX.htm})
+@item When using the Amontec JTAGkey, you have to get the drivers from the Amontec
+homepage (@uref{www.amontec.com}), as the JTAGkey uses a non-standard VID/PID.
+@end itemize
+
+Please note that the ftdi2232 variant (using libftdi) isn't supported under Cygwin.
+You have to use the ftd2xx variant (using FTDI's D2XX) on Cygwin.
+
+In general, the D2XX driver provides superior performance (several times as fast),
+but has the draw-back of being binary-only - though that isn't as worse, as it isn't
+a kernel module, only a user space library.
+
+To build OpenOCD (on both Linux and Cygwin), use the following commands:
+@smallexample
+ ./bootstrap
+@end smallexample
+Bootstrap generates the configure script, and prepares building on your system.
+@smallexample
+ ./configure
+@end smallexample
+Configure generates the Makefiles used to build OpenOCD
+@smallexample
+ make
+@end smallexample
+Make builds the OpenOCD, and places the final executable in ./src/
+
+The configure script takes several options, specifying which JTAG interfaces
+should be included:
+
+@itemize @bullet
+@item
+--enable-parport
+@item
+--enable-parport_ppdev
+@item
+--enable-amtjtagaccel
+@item
+--enable-ft2232_ftd2xx
+@footnote{Using the latest D2XX drivers from FTDI and following their installation
+instructions, I had to use @option{--enable-ft2232_libftd2xx} for the OpenOCD to
+build properly}
+@item
+--enable-ft2232_libftdi
+@item
+--with-ftd2xx=/path/to/d2xx/
+@end itemize
+
+If you want to access the parallel port using the PPDEV interface you have to specify
+both the @option{--enable-parport} AND the @option{--enable-parport_ppdev} option since
+the @option{--enable-parport_ppdev} option actually is an option to the parport driver
+(see @uref{http://forum.sparkfun.com/viewtopic.php?t=3795} for more info).
+
+Cygwin users have to specify the location of the FTDI D2XX package. This should be an
+absolute path containing no spaces.
+
+Linux users should copy the various parts of the D2XX package to the appropriate
+locations, i.e. /usr/include, /usr/lib.

+@node Running
+@chapter Running
+@cindex running openocd
+@cindex --configfile
+@cindex --debug_level
+@cindex --logfile
+@cindex --search
+The OpenOCD runs as a daemon, waiting for connections from clients (Telnet or GDB).
+Run with @option{--help} or @option{-h} to view the available command line arguments.
+
+It reads its configuration by default from the file openocd.cfg located in the current
+working directory. This may be overwritten with the @option{-f <configfile>} command line
+switch.
+
+To enable debug output (when reporting problems or working on OpenOCD itself), use
+the @option{-d} command line switch. This sets the debug_level to "3", outputting
+the most information, including debug messages. The default setting is "2", outputting
+only informational messages, warnings and errors. You can also change this setting
+from within a telnet or gdb session (@option{debug_level <n>}).
+
+You can redirect all output from the daemon to a file using the @option{-l <logfile>} switch.
+
+Search paths for config/script files can be added to openocd by using
+the @option{-s <search>} switch.
+
+@node Configuration
+@chapter Configuration
+@cindex configuration
+The Open On-Chip Debugger (OpenOCD) runs as a daemon, and reads it current configuration
+by default from the file openocd.cfg in the current directory. A different configuration
+file can be specified with the @option{-f <conf.file>} given at the openocd command line.
+
+The configuration file is used to specify on which ports the daemon listens for new
+connections, the JTAG interface used to connect to the target, the layout of the JTAG
+chain, the targets that should be debugged, and connected flashes.

+@item @b{reset_config} <@var{signals}> [@var{combination}] [@var{trst_type}] [@var{srst_type}]
+@cindex reset_config
+The configuration of the reset signals available on the JTAG interface AND the target.
+If the JTAG interface provides SRST, but the target doesn't connect that signal properly,
+then OpenOCD can't use it. <@var{signals}> can be @samp{none}, @samp{trst_only},
+@samp{srst_only} or @samp{trst_and_srst}.
+[@var{combination}] is an optional value specifying broken reset signal implementations.
+@samp{srst_pulls_trst} states that the testlogic is reset together with the reset of
+the system (e.g. Philips LPC2000, "broken" board layout), @samp{trst_pulls_srst} says
+that the system is reset together with the test logic (only hypothetical, I haven't
+seen hardware with such a bug, and can be worked around).
+
+The [@var{trst_type}] and [@var{srst_type}] parameters allow the driver type of the
+reset lines to be specified. Possible values are @samp{trst_push_pull} (default)
+and @samp{trst_open_drain} for the test reset signal, and @samp{srst_open_drain}
+(default) and @samp{srst_push_pull} for the system reset. These values only affect
+JTAG interfaces with support for different drivers, like the Amontec JTAGkey and JTAGAccelerator.
+
+@item @b{jtag_device} <@var{IR length}> <@var{IR capture}> <@var{IR mask}> <@var{IDCODE instruction}>
+@cindex jtag_device
+Describes the devices that form the JTAG daisy chain, with the first device being
+the one closest to TDO. The parameters are the length of the instruction register
+(4 for all ARM7/9s), the value captured during Capture-IR (0x1 for ARM7/9), and a mask
+of bits that should be validated when doing IR scans (all four bits (0xf) for ARM7/9).
+The IDCODE instruction will in future be used to query devices for their JTAG
+identification code. This line is the same for all ARM7 and ARM9 devices.
+Other devices, like CPLDs, require different parameters. An example configuration
+line for a Xilinx XC9500 CPLD would look like this:
+@smallexample
+jtag_device 8 0x01 0x0e3 0xfe
+@end smallexample
+The instruction register (IR) is 8 bits long, during Capture-IR 0x01 is loaded into
+the IR, but only bits 0-1 and 5-7 should be checked, the others (2-4) might vary.
+The IDCODE instruction is 0xfe.

+@itemize @bullet
+@item @b{arm7_9 sw_bkpts} <@option{enable}|@option{disable}>
+@cindex arm7_9 sw_bkpts
+Enable/disable use of software breakpoints. On ARMv4 systems, this reserves
+one of the watchpoint registers to implement software breakpoints. Disabling
+SW Bkpts frees that register again.
+@item @b{arm7_9 force_hw_bkpts} <@option{enable}|@option{disable}>
+@cindex arm7_9 force_hw_bkpts
+When @option{force_hw_bkpts} is enabled, the @option{sw_bkpts} support is disabled, and all
+breakpoints are turned into hardware breakpoints.
+@item @b{arm7_9 dbgrq} <@option{enable}|@option{disable}>
+@cindex arm7_9 dbgrq
+Enable use of the DBGRQ bit to force entry into debug mode. This should be
+safe for all but ARM7TDMI--S cores (like Philips LPC).
+@item @b{arm7_9 fast_writes} <@option{enable}|@option{disable}>
+@cindex arm7_9 fast_writes [DEPRECATED]
+See @option{arm7_9 fast_memory_access} instead.
+@item @b{arm7_9 fast_memory_access} <@option{enable}|@option{disable}>
+@cindex arm7_9 fast_memory_access
+Allow the OpenOCD to read and write memory without checking completion of
+the operation. This provides a huge speed increase, especially with USB JTAG
+cables (FT2232), but might be unsafe if used with targets running at a very low
+speed, like the 32kHz startup clock of an AT91RM9200.
+@item @b{arm7_9 dcc_downloads} <@option{enable}|@option{disable}>
+@cindex arm7_9 dcc_downloads
+Enable the use of the debug communications channel (DCC) to write larger (>128 byte)
+amounts of memory. DCC downloads offer a huge speed increase, but might be potentially
+unsafe, especially with targets running at a very low speed. This command was introduced
+with OpenOCD rev. 60.

+@item @b{arm7_9 write_core_reg} <@var{num}> <@var{mode}> <@var{value}>
+@cindex arm7_9 write_core_reg
+Write a core register, without changing the register cache (as displayed by the

+@node GDB and Openocd
+@chapter GDB and Openocd
+@cindex GDB and Openocd
+Openocd complies with the remote gdbserver protocol, and as such can be used
+to debug remote targets.
+
+@section Connecting to gdb
+@cindex Connecting to gdb
+A connection is typically started as follows:
+@smallexample
+target remote localhost:3333
+@end smallexample
+This would cause gdb to connect to the gdbserver on the local pc using port 3333.
+
+To see a list of available openocd commands type @option{monitor help} on the
+gdb commandline.
+
+Openocd supports the gdb @option{qSupported} packet, this enables information
+to be sent by the gdb server (openocd) to gdb. Typical information includes
+packet size and device memory map.
+
+Previous versions of openocd required the following gdb options to increase
+the packet size and speed up gdb communication.
+@smallexample
+set remote memory-write-packet-size 1024
+set remote memory-write-packet-size fixed
+set remote memory-read-packet-size 1024
+set remote memory-read-packet-size fixed
+@end smallexample
+This is now handled in the @option{qSupported} PacketSize.
+
+@section Programming using gdb
+@cindex Programming using gdb
+
+By default the target memory map is not sent to gdb, this can be enabled by
+the following openocd config option:
+@smallexample
+gdb_memory_map enable
+@end smallexample
+For this to function correctly a valid flash config must also be configured
+in openocd. For speed also configure a valid working area.
+
+Informing gdb of the memory map of the target will enable gdb to protect any
+flash area of the target and use hardware breakpoints by default. This means
+that the openocd option @option{arm7_9 force_hw_bkpts} is not required when
+using a memory map.
+
+To view the configured memory map in gdb, use the gdb command @option{info mem}
+All other unasigned addresses within gdb are treated as ram.
+
+If @option{gdb_flash_program enable} is also used, gdb will be able to
+program any flash memory using the vFlash interface.
+
+gdb will look at the target memory map when a load command is given, if any
+areas to be programmed lie within the target flash area the vFlash packets
+will be used.
+
+Incase the target needs configuring before gdb programming, a script can be executed.
+@smallexample
+target_script 0 gdb_program_config config.script
+@end smallexample
+
+To verify any flash programming the gdb command @option{compare-sections}
+can be used.
+
+@node FAQ
+@chapter FAQ
+@cindex faq
+@enumerate
+@item OpenOCD complains about a missing cygwin1.dll
+
+Make sure you have Cygwin installed, or at least a version of OpenOCD that
+claims to come with all the necessary dlls. When using Cygwin, try launching
+the OpenOCD from the Cygwin shell.
+
+@item I'm trying to set a breakpoint using GDB (or a frontend like Insight or
+Eclipse), but OpenOCD complains that "Info: arm7_9_common.c:213
+arm7_9_add_breakpoint(): sw breakpoint requested, but software breakpoints not enabled".
+
+GDB issues software breakpoints when a normal breakpoint is requested, or to implement
+source-line single-stepping. On ARMv4T systems, like ARM7TDMI, ARM720t or ARM920t,
+software breakpoints consume one of the two available hardware breakpoints,
+and are therefor disabled by default. If your code is running from RAM, you
+can enable software breakpoints with the @option{arm7_9 sw_bkpts enable} command. If
+your code resides in Flash, you can't use software breakpoints, but you can force
+OpenOCD to use hardware breakpoints instead: @option{arm7_9 force_hw_bkpts enable}.
+
+@item When erasing or writing LPC2000 on-chip flash, the operation fails sometimes
+and works sometimes fine.
+
+Make sure the core frequency specified in the @option{flash lpc2000} line matches the
+clock at the time you're programming the flash. If you've specified the crystal's
+frequency, make sure the PLL is disabled, if you've specified the full core speed
+(e.g. 60MHz), make sure the PLL is enabled.
+
+@item When debugging using an Amontec Chameleon in its JTAG Accelerator configuration,
+I keep getting "Error: amt_jtagaccel.c:184 amt_wait_scan_busy(): amt_jtagaccel timed
+out while waiting for end of scan, rtck was disabled".
+
+Make sure your PC's parallel port operates in EPP mode. You might have to try several
+settings in your PC Bios (ECP, EPP, and different versions of those).
+
+@item When debugging with the OpenOCD and GDB (plain GDB, Insight, or Eclipse),
+I get lots of "Error: arm7_9_common.c:1771 arm7_9_read_memory():
+memory read caused data abort".
+
+The errors are non-fatal, and are the result of GDB trying to trace stack frames
+beyond the last valid frame. It might be possible to prevent this by setting up
+a proper "initial" stack frame, if you happen to know what exactly has to
+be done, feel free to add this here.
+
+@item I get the following message in the OpenOCD console (or log file):
+"Warning: arm7_9_common.c:679 arm7_9_assert_reset(): srst resets test logic, too".
+
+This warning doesn't indicate any serious problem, as long as you don't want to
+debug your core right out of reset. Your .cfg file specified @option{jtag_reset
+trst_and_srst srst_pulls_trst} to tell the OpenOCD that either your board,
+your debugger or your target uC (e.g. LPC2000) can't assert the two reset signals
+independently. With this setup, it's not possible to halt the core right out of
+reset, everything else should work fine.
+
+@item When using OpenOCD in conjunction with Amontec JTAGkey and the Yagarto
+Toolchain (Eclipse, arm-elf-gcc, arm-elf-gdb), the debugging seems to be
+unstable. When single-stepping over large blocks of code, GDB and OpenOCD
+quit with an error message. Is there a stability issue with OpenOCD?
+
+No, this is not a stability issue concering OpenOCD. Most users have solved
+this issue by simply using a self-powered USB Hub, which they connect their
+Amontec JTAGkey to. Apparently, some computers do not provide a USB power
+supply stable enough for the Amontec JTAGkey to be operated.
+
+@item When using the Amontec JTAGkey, sometimes OpenOCD crashes with the
+following error messages: "Error: ft2232.c:201 ft2232_read(): FT_Read returned:
+4" and "Error: ft2232.c:365 ft2232_send_and_recv(): couldn't read from FT2232".
+What does that mean and what might be the reason for this?
+
+First of all, the reason might be the USB power supply. Try using a self-powered
+hub instead of a direct connection to your computer. Secondly, the error code 4
+corresponds to an FT_IO_ERROR, which means that the driver for the FTDI USB
+Chip ran into some sort of error - this points us to a USB problem.
+
+@item When using the Amontec JTAGkey, sometimes OpenOCD crashes with the following
+error message: "Error: gdb_server.c:101 gdb_get_char(): read: 10054".
+What does that mean and what might be the reason for this?
+
+Error code 10054 corresponds to WSAECONNRESET, which means that the debugger (GDB)
+has closed the connection to OpenOCD. This might be a GDB issue.
+
+@item In the configuration file in the section where flash device configurations
+are described, there is a parameter for specifying the clock frequency for
+LPC2000 internal flash devices (e.g.
+@option{flash bank lpc2000 0x0 0x40000 0 0 lpc2000_v1 0 14746 calc_checksum}),
+which must be sepcified in kilohertz. However, I do have a quartz crystal of a
+frequency that contains fractions of kilohertz (e.g. 14,745,600 Hz, i.e. 14,745.600 kHz).
+Is it possible to specify real numbers for the clock frequency?
+
+No. The clock frequency specified here must be given as an integral number.
+However, this clock frequency is used by the In-Application-Programming (IAP)
+routines of the LPC2000 family only, which seems to be very tolerant concerning
+the given clock frequency, so a slight difference between the specified clock
+frequency and the actual clock frequency will not cause any trouble.
+
+@item Do I have to keep a specific order for the commands in the configuration file?
+
+Well, yes and no. Commands can be given in arbitrary order, yet the devices
+listed for the JTAG scan chain must be given in the right order (jtag_device),
+with the device closest to the TDO-Pin being listed first. In general,
+whenever objects of the same type exist which require an index number, then
+these objects must be given in the right order (jtag_devices, targets and flash
+banks - a target references a jtag_device and a flash bank references a target).
+
+@item Sometimes my debugging session terminates with an error. When I look into the
+log file, I can see these error messages: Error: arm7_9_common.c:561
+arm7_9_execute_sys_speed(): timeout waiting for SYSCOMP
