* 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]
* corrective fix for MinGW GNU C99 printf complianceRedirect 'Slash' NIL2009-10-192-6/+8
| | | | | | | | | | | | | | Compilation on cygwin, using gcc v3 with option -mno-cygwin, currently produces a large number of the following warnings: warning: `gnu_printf' is an unrecognized format function type These have been introduced with the recent MinGW GNU C99 printf compliance patch, as gnu_printf was only introduced with gcc v4.4 and is not recognized with earlier versions. The attached fix adds gcc version detection to the previous patch to avoid the problem.

* safer conversion to HANDLER on MinGW-W64Redirect 'Slash' NIL2009-10-171-2/+2
| | | | | Assign to "intptr_t", which on some versions of MS-Windows will widen the variable; then cast to HANDLE.
* More MinGW C99 printf complianceRedirect 'Slash' NIL2009-10-173-6/+23
| | | | | | | | 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".
* jim-eventloop for MinGW-w64Redirect \"Slash\" NIL2009-10-172-2/+2
| | | | | | | | Use JIM_WIDE_MODIFIER for the sscanf format, and apply it for MINGW32 as well as other Windows environments. (Microsoft doesn't conform to the C99 standard, and uses "%I64d" not "%lld" for "long long".) NB: __MINGW32__ should work on both w32 and w64,.

* xscale: better fix for debug_handler.binDavid Brownell2009-10-165-29/+27
| | | | | | | | | | | | | 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.)

* another portability updateDavid Brownell2009-10-141-4/+4

* portability updatesDavid Brownell2009-10-144-11/+12
| | | | | | | | | 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>
* doc updates to match "help" betterDavid Brownell2009-10-141-52/+5
| | | | | | | | | | | | | | | | | | | This makes the documentation a closer match to "help" output: - "pathmove" somehow was not documented in the User's Guide - "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width" are new; both needed descriptions. - Removed two undocumented and fairly useless script mechanisms: * production/production_info/production_test ... using it, requires replacing everything; so having it adds no value. * cpu ... way out of date; hopeless to keep that current Note that anyone using that "production" stuff already defines their own procedures, and can keep using them with no change.

| | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | Just fill out the rest of the cache line with NOPs; don't change the record of how much data we consumed.

| | | | | | | | | | | | | | | | | | | | We added two overridable procedures; document them, and the two jtag arp_* operations they necessarily expose.

* add overridable Tcl "init_reset"David Brownell2009-10-081-8/+22
| | | | | | | | | | | This abstracts the "jtag arp_init-reset" call into a method called from OpenOCD startup and reset processing. Platforms which have different requirements for how such hard resets must be performed can now override "init_reset" instead of needing to rebuild custom hacked versions of the server.

| | | | | | | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Stop ignoring most scan chain validation errorsDavid Brownell2009-10-082-15/+50
| | | | | | | | | | | | | | | | Among other things this causes startup errors to kick in the fallback "reset harder" logic during server startup. Comments are also updated a bit, explaining what the various error paths signify (in at least my observation). There's one class of validation error that we can still plausibly ignore: when wrong IDCODE values are observed. This change seems to have helped make an OMAP5912 behave much more reliably. There's still some post-reset flakiness, but it's unrelated to scan verification. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
