* Cortex-M3: remove exports and forward declsDavid Brownell2009-10-282-189/+144
| | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Make most functions static, and fix some line-too-long issues. Delete some now-obviously-unused code. The forward decls are just code clutter; move their references later, after the normal declarations. (Or vice versa.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM926: remove exports and forward declsDavid Brownell2009-10-281-122/+127
| | | | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Only the Feroceon code builds on this, so only routines it reuses should be public.. Make most remaining functions static, and fix some of the line-too-long issues. The forward decls are just code clutter; move their references later, after the normal declarations. Turns out we don't need even one forward declaration in this file. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* bugfix: stack corruption loading IHex imagesFranck HÉRÉSON2009-10-282-1/+22
| | | | | | | | | | | | The Hex parser uses a fixed number of sections. When the number of sections in the file is greater than that, the stack get corrupted and a CHECKSUM ERROR is detected which is very confusing. This checks the number of sections read, and increases IMAGE_MAX_SECTIONS so it works on my file. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Add script to test the release process.Zachary T Welch2009-10-271-0/+121
| | | | | Runs the release.sh script in a freshly cloned repository, charting one hypothetical future of OpenOCD's lineage.
* Rewrite release script to use GIT.Zachary T Welch2009-10-272-512/+210
| | | | | | | | Update documentation to reflect GIT methodology. Rewrite release.sh script to use appropriate process. With this update, tools/release.sh can be used for producing private release tags on local branches. The documentation still needs work, but their use for v0.3.x should help rectify the deficiences.

* Improve .gitignore rules.Zachary T Welch2009-10-271-1/+5
| | | | | | | | A '.*' rule prevents the 'git submodule add' from correctly adding the first submodule, because it creates the .gitmodule file. This file will not be added (without -f) result in incomplete submodule commits. The new rules mask the specific files present in my own build tree, but additional rules may be needed to hide other types of temporary files.
* ARM: fix single-step of Thumb unconditional branchNicolas Pitre2009-10-271-2/+2
| | | | | | | | | Only type 1 branch instruction has a condition code, not type 2. Currently they're both tagged with ARM_B which doesn't allow for the distinction. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: fix target address when disassembling Thumb BLXNicolas Pitre2009-10-271-0/+1
| | | | | | | | A Thumb BLX instruction is branching to ARM code, and therefore the first 2 bits of the target address must be cleared. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM: fix Thumb mode handling when single-stepping register based branch insnsNicolas Pitre2009-10-261-22/+33
| | | | | | | | | | | | | | | | | | | Currently, OpenOCD is always caching the PC value without the T bit. This means that assignment to the PC register must clear that bit and set the processor state to Thumb when it is set. And when the PC register value is transferred to another register or stored into memory then the T bit must be restored. Discussion: It is arguable if OpenOCd should have preserved the original PC value which would have greatly simplified this code. The processor state could then be obtained simply by getting at bit 0 of the PC. This however would require special handling elsewhere instead since the T bit is not always relevant (like when PC is used with ALU insns or as an index with some addressing modes). It is unclear which way would be simpler in the end. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: allow proper single stepping of Thumb BL and BLX instructionsNicolas Pitre2009-10-261-0/+12
| | | | | | | | | | | | | | Whenever an unconditional branch with the H bits set to 0b10 is met, the offset must be combined with the offset from the following opcode and not ignored like it is now. A comment in evaluate_b_bl_blx_thumb() suggests that the Thumb2 decoder would be a simpler solution. That might be true when single-stepping of Thumb2 code is implemented. But for now this appears to be the simplest solution to fix Thumb1 support. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: call thumb_pass_branch_condition() only for actual branch opcodesNicolas Pitre2009-10-261-8/+6
| | | | | | | | | | | | | | Calling it first with every opcodes and then testing if the opcode was indeed a branch instruction is wasteful and rather strange. If ever thumb_pass_branch_condition() has side effects (say, like printing a debugging traces) then the result would be garbage for most Thumb instructions which have no condition code. While at it, let's make the nearby code more readable by reducing some of the redundant brace noise and reworking the error handling construct.

* omap3530: target reset/init improvementsDavid Brownell2009-10-261-15/+25
| | | | | | | | | | | | | | | | | Now I can issue "reset halt" and have everything act smoothly; the vector_catch hardware is obviously not kicking in, but the rest of the reset sequence acts sanely. - TAP "setup" event enables the DAP, not omap3_dbginit (resolving a chicken/egg bug I noted a while back) - Remove stuff from omap3_dbginit which should never be used in event handlers - Cope better with slow clocking during reset Also, stop hard-wiring the target name: use the input params in the standard way, and set up $_TARGETNAME as an output param.

| | | | | | | | | | | | | | | | | | | | | | This is the very basic board config for the balloon3 board cpu JTAG channel. The rest of the config comprises another 14 .cfg files which I suspect openocd doesn't really want all of. I'm still not sure how to deal with this. I'll post another mail/patch to discuss.

* JTAG: simple autoprobingDavid Brownell2009-10-262-14/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic autoprobing support for the JTAG scan chains which cooperate. To use, you can invoke OpenOCD with just: - interface spec: "-f interface/...cfg" - possibly with "-c 'reset_config ...'" for SRST/TRST - possibly with "-c 'jtag_khz ...'" for the JTAG clock Then set up config files matching the reported TAPs. It doesn't declare targets ... just TAPs. So facilities above the JTAG and SVF/XSVF levels won't be available without a real config; this is almost purely a way to generate diagnostics. Autoprobe was successful with most boards I tested, except ones incorporating C55x DSPs (which don't cooperate with this scheme for IR length autodetection). Here's what one multi-TAP chip reported, with the "Warn:" prefixes removed: clock speed 500 kHz There are no enabled taps. AUTO PROBING MIGHT NOT WORK!! AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x2b900f0f ..." AUTO auto1.tap - use "jtag newtap auto1 tap -expected-id 0x07926001 ..." AUTO auto2.tap - use "jtag newtap auto2 tap -expected-id 0x0b73b02f ..." AUTO auto0.tap - use "... -irlen 4" AUTO auto1.tap - use "... -irlen 4" AUTO auto2.tap - use "... -irlen 6" no gdb ports allocated as no target has been specified The patch tweaks IR setup a bit, so we can represent TAPs with undeclared IR length.

* xscale: always reload handler after resetDavid Brownell2009-10-252-19/+11
| | | | | | | | | | | | | | | | | | | | Remove needless debug handler state. - "handler_installed" became wrong as soon as the second TRST+SRST reset was issued ... so the handler was never reloaded after the reset removed it from the mini-icache. This fixes the bug where subsequent resets fail on PXA255 (if the first one even worked, which is uncommon). Other XScale chips would have problems too; PXA270 seems to have, IXP425 maybe not. - "handler_running" was never tested; it's pointless. Plus a related bugfix: invalidate OpenOCD's ARM register cache on reset. It was no more valid than the XScale's mini-icache. (Though ... such invalidations might be better done in "SRST asserted" callbacks.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | | | | | | | | | | - Use the name mappings all the other code uses: + name-to-state ... needed to add one special case + state-to-name - Improve various diagnostics: + don't complain about a "valid" state when the issue is actually that it must be "stable" + say which command was affected - Misc: + make more private data and code be static + use public DIM() not private dimof() + shorten the affected lines Re the mappings, this means we're more generous in inputs we accept, since case won't matter. Also our output diagnostics will be a smidgeon more informative, saying "RUN/IDLE" not just "IDLE" (emphasizing that there can be side effects).
