| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | previous nonfunctional cortex_a8 code with something that at least basically works (for halt/step/resume, without MMU) even if it is incomplete. (With tweaks from Øyvind, and cleanup from Dave.) This code has mainly been developed and tested against R1606, it has been built and tested against R2294 where it runs but step and resume commands are broken due to regression (which should be fixed now). This code is really written for OMAP3530. It doesn't identify debug resources using generic DAP calls to scan the ROM table, or perform topology detection. The OMAP3530 DAP exposes two memory access ports: - Port #0 is connected to L3 interconnect (the main bus) with passthrough to the L4 EMU bus ... so it will be used for most memory accesses. - Port #1 is connected to a dedicated debug bus (L4 EMU), with access to L4 Wakeup, and holds the ROM table ... so it must be used for most debug and control operations. The are some defines to handle this in cortex_a8.c, which should be replaced with more general code. Having access to another Cortex-A8 implementation would help get that right. git-svn-id: svn://svn.berlios.de/openocd/trunk@2609 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* David Brownell Subset of Cortex-A8 support from Magnus: create an armv7a fileoharboe2009-08-253-0/+479
| | | | | | | | | | | | | | | | | | | and seed it with DAP access support using the current ADIv5 code. (With tweaks and cleanup from Øyvind and Dave.) The ARMv7-AR architecture manual is not publicly available (even in subset form like the ARMv7-M spec), so it's hard to distinguish between the Cortex-A8 implementation and the ARMv7-A architecture. The register set presumably is architectural, and so it's stored here; it's like earlier ARMs, with small additions. Ditto the instruction set, though Thumb2 support is used (extending Thumb support from ARMv6 with more 32-bit instructions) and there's this ThumbEE thing too. There is a new "debug monitor" mode, not yet fully addressed here, to support debugging in environments (like motor control) where halting debug mode is inadvisable. git-svn-id: svn://svn.berlios.de/openocd/trunk@2608 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | Simplify dumping of register lists by only printing cached values if they are marked as valid. Most of the time, they are invalid; so printing *any* value is just misleading. Note that for ARM7 and ARM9 most EmbeddedICE registers (except for debug status) could be cached most of the time; and their register cache isn't maintained properly (many accesses seem to bypass that cache code). git-svn-id: svn://svn.berlios.de/openocd/trunk@2594 b42882b7-edfa-0310-969c-e2dbd0fdcd60

Users can Work around that (for now) by re-assigning the desired config after reset. Also fixes "target halted due to target-not-halted" goof.
