Passes cmd_ctx into parse_load_image_command_args for reporting the
parsing errors therein.
|
|
|
|
|
|
This helper eliminates significant amount of redundant code in command
handler functions throughout the system. It wraps the lower-level
parse_* macros to implement a policy for reporting parse errors to the
active command context (cmd_ctx). If errors do occur, this macro causes
the calling function to abort with the proper return code.

The arm920t has a concept of read modify write cycles
that may have to be represented in the mrcmcr interface
eventually.

Highlight that the "-expected-id" probably comes from vendor
documentation, and that it *should* be used where possible.
Don't use ircapture/irmask in examples, to help discourage
use of those params when they're not required. Explain a
bit better about why/when those params get used.

Fail watchpoint_add() if it's the same address but the
parameters are different ... don't just assume having
the same address means the same watchpoint! (Note that
overlapping watchpoints aren't detected...)
Handle unrecognized return codes more sanely; don't exit()!
And describe command params right.

Expose most DWT registers via Tcl; there are a few more, but
those are mostly for profiling along with the ITM. Having
this set available enables operations which aren't possible
with just the standard watchpoint operations.
The cycle counter may be interesting. Turn it on after reset
by setting the LSB of the dwt_ctrl register, and it counts
CPU clocks. You can program the comparator 0 watchpoint to
trigger on a given cycle count, rather than a data address.
Likewise, comparator 1 may be able to match data values given
address matches from one or two other comparators. (Not all
hardware supports this capability though; try it. That is
something the standard watchpoint methods should eventually
handle, for the single address case.)
Minor cleanup: remove needless functional indirection for
exposing the v7m architctural registers.

There's no reason to read which interrupts are enabled from
the NVIC; that state isn't used. Plus, it's highly dynamic
since firmware can change it at any time; remove the support
for those state records.
Remove duplicate definition of DWT_CTRL address; shrink a line.

Fix the watchpoint error checks, and do them in add(), not later
in set() when it's mostly too late. Support the full range of
watchpoint sizes (1 to 32K bytes each), and check alignments.
Minor cleanup of DWT access: shrink lines, use "+" for address
calculations, comment a few issues. Add debug message reporting
DWT capabilities, matching the message for FBP, and some minor
code and spec review comments.

Add Doxygen for the exported ARMv7-M interfaces.
Make the non-exported stuff static. Remove functions and
data which are now observably unused.
Add comment about a small speedup that the run_algorithm()
logic could use. Shrink a few too-long lines.

functions have not been implemented yet vs. will
not be implemented(e.g. cortex m3).

The quit entry point was not being invoked. Just a source
of confusion at this point. XScale ran 100x reset upon
quit, but that code made no sense, wasn't commented
and never invoke.

Config for Intel's "Lubbock" PXA255 development board. Even more
so than the PXA255 itself, this is obsolete. AFAIK this was the
first generally available development platform for PXA255. Intel
stopped providing these after other devel boards became available.
One interesting thing about this board from the OpenOCD perspective
is probably its flash configuration. Each bank is 32 bits wide,
built from two 16-bit StrataFlash chips wired in parallel. This
doubles throughput ... it reads/writes 32 bits in the time a single
chip takes to write just 16 bits.
This conf mostly works, given XScale bugfixes, but has some issues
(notably: no access to the on-board SDRAM) flagged by FIXMEs.

We currently do something unusual: version codes in config.in get
updated after the release, which means that "git describe" won't
match up to development version labels. Comment that trouble spot.
We can fix this by switching away from the major/minor/micro type
release numbering, as various other projects have done. The major
numbers basically don't tend to change, and doing a good job with
micro versions is so annoying that they rarely change either.

Contrast releases to git snapshot tarballs. Mention that
releases have some quality-improvement focus, with special
non-"dev" version IDs. Explain more about version IDs,
using "openocd -v" to see them, etc;
Make release milestone info be less specific about timing,
and presume we have both a merge window and an RC stage.
Rework the release process information to match reality a
bit more closely. Reference the version.sh script (in one
place the wrong script was referenced). Bugfix branches
get special treatment, while non-bugfix releases are more
or less what *defines* being the mainline branch.

The "source" command isn't accepted by ASH; easy to fix.
Failures with "-e" are harder to fix. Remove the "-e"
(for now) and force bash, for safety.
Un-obfuscate the release steps, by using names instead
of numbers. Comment the version-number manipulation.

To support breakpoints, flush data cache line and invalidate

Fixed bug: if virtual address for working memory was not specified
and MMU was enabled, then address 0 would be used.
Require working address to be specified for both MMU enabled
and disabled case.
For some completely inexplicable reason this fixes the regression
in svn 2646 for flash write in arm926ejs target. The logs showed
that MMU was disabled in the case below:
