* arm9tdmi vector_catch: reserved means "don't use"David Brownell2009-10-232-3/+2
| | | | | | | Bit 5 shouldn't be used. Remove all support for modifying it. Matches the exception vector table, of course ... more than one bootloader uses that non-vector to help distinguish valid boot images from random garbage in flash.

* Ferocion: fix corruption of r0 when resuming Thumb modeNicolas Pitre2009-10-221-2/+1
| | | | | | | | The wrong variable (pc instead of r0) was used. Furthermore, someone did cover this error by stupidly silencing the compiler warning that occurred before a dummy void reference to r0 was added to the code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* have "reg" command print cache names tooDavid Brownell2009-10-221-0/+2
| | | | | | | When dumping over 100 registers (as on most ARM9 + ETM cores), aid readability by splitting them into logical groups. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ETM: rename registers, doc tweaksDavid Brownell2009-10-221-47/+54
| | | | | | | | | | | | | | | The register names are perversely not documented as zero-indexed, so rename them to match that convention. Also switch to lowercase suffixes and infix numbering, matching ETB and EmbeddedICE usage. Update docs to be a bit more accurate, especially regarding what the "trigger" event can cause; and to split the issues into a few more paragraphs, for clarity. Make "configure" helptext point out that "oocd_trace" is prototype hardware, not anything "real". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* fix single step of bx instruction going into Thumb modeNicolas Pitre2009-10-191-1/+1
| | | | | | | | Without this fix, the following code cannot be single stepped: add ip, pc, #1 bx ip [thumb code here]
* More MinGW C99 printf complianceRedirect 'Slash' NIL2009-10-171-1/+2
| | | | | | | | Passing "--std=gun99" is unfortunately not sufficient to make current MinGW compilers conform with respect to checking printf format strings. (The C runtime seems not to have problems.) Fix by using a "gnu_printf" format specifier not "printf".
* build tweak for bin2charDavid Brownell2009-10-171-3/+4

* xscale: better fix for debug_handler.binDavid Brownell2009-10-164-26/+20
| | | | | | | | | | | | | Generate a C struct with the data, and use that, instead of an assembly language file. The assembly language causes issues on Darwin and MS-Windows, which don't necessarily use GNU AS; or if they do, don't necessarily use its ELF syntax. It's also better in two other ways: fewer global symbols; and the init-time size check gets optimized away at compile time. (Unless it fails, in which case bigger chunks of the file vanish.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* portability updatesDavid Brownell2009-10-142-3/+3
| | | | | | | | | Based on some patches from <redirect.slash.nil@gmail.com> for preliminary Win64 compilation. More such updates are needed, but they need work. Compile tested on 64 and 32 bit Linuxes, and Cygwin. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* xscale: stackframe corruption bugfixDavid Brownell2009-10-131-36/+18
| | | | | | | | | | | Resolve a "FIX" comment; yes that was superfluous given that the JTAG core does that check by default. It was also buggy since it wrote to a stack frame that went away before the write happened!! Other fixes: remove pointless malloc(); zero-init scan_field_t values wherever they appear; whitespace scrub; spelling fix. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* simplify XScale debug handler installationDavid Brownell2009-10-124-42/+58
| | | | | | | | | | | | | | | | | | | Load the XScale debug handler from the read-only data section instead of from a separate file that can get lost or garbaged. This eliminates installation and versioning issues, and also speeds up reset handling a bit. Plus some minor bits of cleanup related to loading that handler: comments about just what this handler does, and check fault codes while writing it into the mini-icache. The only behavioral changes should be cleaner failure modes after errors during handler loading, and being a bit faster. NOTE: presumes GNU assembly syntax, with ".incbin"; and ELF, because of the syntax of the ".size" directive. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* more xscale cleanup (mostly removing JTAG hooks)David Brownell2009-10-122-88/+65
| | | | | | | | | | | | | | | | Streamline/shrink some needless JTAG stuff: - Use #defines for the JTAG instructions; they can't ever change - Remove an unused (!) shadow of tap->ir_length - Stop using a copy of target->tap - Don't bother saving the variant after sanity checking ir_length Also, make target_create() work as on other targets: build the register cache later, making init_target() no longer be a NOP. Handle malloc failure; remove a comment that was obsoleted by the not-so-new target syntax. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| * xscale bugfix to handler loadingDavid Brownell2009-10-111-2/+2
| | | | | | | | | | | | | | | | | | Just fill out the rest of the cache line with NOPs; don't change the record of how much data we consumed. Otherwise the count of how much data is left can roll over from positive to negative ("VERY positive") and skip the loop termination of zero.

| * xscale minor cleanupDavid Brownell2009-10-111-43/+31
| | | | | | | | | | | | | | | | | | | | | | | | Add a header comment referencing useful XScale specs. Make most data static, and the tables readonly. Scrub extra blank lines. Return fault codes from one routine. Remove a needless NOP methood. (BUGFIX) When we update R0, mark R0 as dirty/valid ... not R15/PC! Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | | Observed: openocd: core.c:318: jtag_checks: Assertion `jtag_trst == 0' failed. The issue was that nothing disabled background polling during calls from the TCL shell to "jtag_reset 1 1". Fix by moving the existing poll-disable mechanism to the JTAG layer where it belongs, and then augmenting it to always pay attention to TRST and SRST.
