-- Isolate all TCL command support:
- - Pure C CLI implementations using --disable-builtin-tcl.
+- Isolate all TCL command support:
+ - Pure C CLI implementations using --disable-builtin-tcl.
- Allow developers to build new dongles using OpenOCD's JTAG core.
- At first, provide only low-level JTAG support; target layer and
above rely heavily on scripting event mechanisms.
The following tasks have been suggested for cleaning up the JTAG layer:
- use tap_set_state everywhere to allow logging TAP state transitions
-- Encapsulate cmd_queue_cur_state and related varaible handling.
+- Encapsulate cmd_queue_cur_state and related variable handling.
- add slick 32 bit versions of jtag_add_xxx_scan() that avoids
buf_set_u32() calls and other evidence of poor impedance match between
API and calling code. New API should cut down # of lines in calling
Workaround: use "tms_sequence long" @par

+The following tasks have been suggested for improving OpenOCD's JTAG
interface support:
- rework USB communication to be more robust. Two possible options are:
-# rewrite implementation to use non-blocking I/O
- J-Link driver:
- fix to work with long scan chains, such as R.Doss's svf test.
-- FT2232 (libftdi):
- - make performance comparable to alternatives (on Win32, D2XX is faster)
- - make usability comparable to alternatives
- Autodetect USB based adapters; this should be easy on Linux. If there's
more than one, list the options; otherwise, just select that one.

- regression: "reset halt" between 729(works) and 788(fails): @par
https://lists.berlios.de/pipermail/openocd-development/2009-July/009206.html
+- registers
+ - add flush-value operation, call them all on resume/reset
- mcr/mrc target->type support
- missing from ARM920t, ARM966e, XScale.
It's possible that the current syntax is unable to support read-modify-write
use hardware stepping if available.
- mdb can return garbage data if read byte operation fails for
a memory region(16 & 32 byte access modes may be supported). Is this
- a bug in the .MX31 PDK init script? Try on i.MX31 PDK:

mdw 0xb80005f0 0x8, mdh 0xb80005f0 0x10, mdb 0xb80005f0 0x20. mdb returns
garabage.
- implement missing functionality (grep FNC_INFO_NOTIMPLEMENTED ...)
- Thumb2 single stepping: ARM1156T2 needs simulator support
-- Cortex A8 support (ML)
+- Cortex-A8 support (ML)
- add target implementation (ML)
+- Cortex-M3 support
+ - when stepping, only write dirtied registers (be faster)
+ - when connecting to halted core, fetch registers (startup is quirky)
- Generic ARM run_algorithm() interface
- tagged struct wrapping ARM instructions and metadata
- not revision-specific (current: ARMv4+ARMv5 -or- ARMv6 -or- ARMv7)
- usable with at least arm_nandwrite() and generic CFI drivers
+- ETM
+ - don't show FIFOFULL registers if they're not supported
+ - use comparators to get more breakpoints and watchpoints
+ - add "etm drivers" command
+ - trace driver init() via examine() paths only, not setup()/reset
- MC1322x support (JW/DE?)
- integrate and test support from JW (and DE?)
- get working with a known good interface (i.e. not today's jlink)

@section thelistflash Flash Support
- finish documentation for the following flash drivers:
- avr
- - ecosflash
- pic32mx
- ocl
- str9xpec
+- Don't expect writing all-ones to be a safe way to write without
+ changing bit values. Minimally it loses on flash modules with
+ internal ECC, where it may change the ECC.
+ - NOR flash_write_unlock() does that between sectors
+ - there may be other cases too
+
+- Make sure all commands accept either a bank name or a bank number,
+ and be sure both identifiers show up in "flash banks" and "nand list".
+ Right now the user-friendly names are pretty much hidden...

@subsection thelistflashcfi CFI
- finish implementing bus width/chip width handling (suggested by NC)
- automatically detect the features that are available, unless
options were specifically provided to configure
- provide a report of the drivers that will be build at the end of

- -# Add @c buildstrap script to assist with boostrap and configure steps.
+ -# Add @c buildstrap script to assist with bootstrap and configure steps.
- automatically build tool-chains required for cross-compiling

-- review and clean up interface/target/flash APIs
+- review and clean up interface/target/flash APIs
The following strategic tasks will require ambition, knowledge, and time
to complete:
- Develop milestone and release guidelines, processes, and scripts.
- Develop "style" guidelines (and scripts) for maintainers:
- reviewing patches
- - committing to Subversion
-- Review The Guide for OpenOCD Users for documentation errors or omissions
-- Update The Manual for OpenOCD Developerrs:
+ - committing to git
+- Review Users' Guide for documentation errors or omissions
+ - "capture" and "ocd_find" commands
+ - "ocd_" prefix on various stuff
+- Update Developer's Manual (doxygen output)
- Add documentation describing the architecture of each module
- Provide more Technical Primers to bootstrap contributor knowledge
