David Brownell <david-b@pacbell.net> Update docs to say that "arm7_9 dbgrq enable" is the default
on ARM9 cores, and update the DaVinci config files so they
no longer explicitly specify it.
Fix certain arm926ejs targets(e.g. i.MX27) which report an unknown MOE(method of entry) - interpret this as dbgrq. "reset run" + "halt" + "step" now works.
The late birth of the NEWS file also caused me to revisit the release
process once again and reconsider it in some detail. In doing so,
some further revisions to the process were required:
1) The URL of the repository is embedded in the released code.
- The packages need to be created from the tagged branch.
- The URL then points to where to get the tagged code.
2) Improve the instructions for NEWS handling.
- NEWS file must be updated for each release; describe that process.
- The NEWS file should be archived an recreated for each release.
3) Add detail steps for the berliOS release process.
4) Minor cleanups to release process doxygen markup.
Updates to private TAP state tables in amtjtagaccel interface driver.
The first change is the neccesary one to correct a long-standing bug that
caused the IDCODE to be shifted by one bit too many. This was caused by
an incorrect path from state RESET to state DRSHIFT.
The value of those 2 bytes were 0x8a and 0x04. This means that the
bitstream to do this transition is 0b 00100 01010 (send LSB first). This
will bring you from the reset state to the shift state; however, you
enter the shift-state twice, which explains why the ID-CODE that will be
read next will be shifted 1 bit. The fix changes these to 0x05 and 0x00.
This will send the bitstream 0b 00101 (send LSB first). This will bring
the TAP controller from the RESET state to the DRSHIFT state directly,
without entering the DRSHIFT state twice.
After checking the whole table, two other transitions were found that
could be optimized (5 bits in stead of 10 bits).
Summary off all changes:
From To Old values Old Bitstream New values New Bitstream Remarks
---- ------- ---------- ------------- ---------- ------------- -------
RESET DRSHIFT 0x8a 0x04 0b00100 01010 0x05 0x00 0b00101 1,2
IDLE DRSHIFT 0x85 0x08 0b01000 00101 0x04 0x00 0b00100 2
IDLE IRSHIFT 0x8b 0x08 0b01000 01011 0x06 0x00 0b00110 2
Fix intermittent J-Link interface startup failures:
- Use usb_reset to ensure selected dongle is in known good state.
- Assert emulator reset durning status check to prevent supurious failures.
- Eliminate status check loop; not needed due to other fixes.
Major update to release process documentation:
- Provide overview of OpenOCD versioning schema.
- Outline responsibilities and authority of the release manager.
- Explain the need for flexibility in the release schedule.
- Add and refine the release process steps.
- Include tutorials for using new release script.
- Many more improvements, too numerous to list.
David Brownell <david-b@pacbell.net> Fix two texinfo formatting bugs. The first was visible by
reading the output, and both were reported in openocd.log
after making the PDF.
More minor improvements to README to help polish the 0.2.0 release:
- Add note about Ubuntu 8.04 (in lieu of starting a README.Linux file).
- Fix introductory paragraph to Bulding OpenOCD
- Remove some vestigial texinfo markup.
Prepare the DaVinci PLL code to support the version 0x0E module
used in newer chips (e.g. dm365): rename the original code so
it's specific to version 0x02 PLL modules, and update the dm355evm
code to use that new name.
Fix two minor bugs in that version 2 code: sysclk3 setup used
the sysclk2 divider address (affecting video processing on dm355,
no worry for now) and sysclk2 setup had a syntax error.
Also minor fixups to dm355evm, mostly to permit use of RTCK.

Move packaging, configuration, and compilation of OpenOCD out of
the User's Guide and into README, where it can be used by users
before configuring and compiling the documentation.
Improve notes about required Subversion repository build steps.
Add reference to the standard GNU INSTALL file.

This patch adds support for the Luminary Micro LM3S9B90 target and

Luminary In-Circuit Debug Interface (ICDI) Board, so this is added as a

Add "jtag names" command, mirroring "target names" but returning
TAP names instead of target names. This starts letting TAPs be
manipulated in scripts ... much like what works now for targets.
It's a bit limited just yet, since "jtag cget $TAPNAME" doesn't
expose all TAP attributes. "$TARGETNAME cget" is more functional.

Improve the PXA255 target config: move all that board-specific
setup to the pxa255_sst board.cfg, to which it evidently belongs
(it's the only PXA255 board now included).
Provide the PXA255 JTAG id from Intel docs, and add a comment
about how this chip is now EOL'd (last orders taken).
Note that I still can't get my old PXA255 board to work. There's
something broken in the reset sequence, which is preventing the
TAP from coming up at all. Old mailing list posts suggest this
is a longstanding bug...

Warn when people (or scripts) use numeric identifiers for TAPs,
instead of dotted.name values. We want this usage to go away,
so that for example adding more TAPs doesn't cause config scripts
to break because some sequence number changed.
It's been deprecated since late 2008, but putting a warning on
this should help us remove it (say, in June 2010) by helping to
phase out old (ab)usage in config scripts.
Other than in various config files, the only code expecting such
a number was the almost unused str9xpec driver. This code was
changed to use the TAP it was passed, instead of making its own
dubious lookup and ignoring that TAP.
