* David Brownell <david-b@pacbell.net> ARM disassembly support for about five ↵oharboe2009-08-281-6/+345
| | | | | | | | | | | | | | | | | | dozen non-Thumb instructions that were added after ARMv5TE was defined: - ARMv5J "BXJ" (for Java/Jazelle) - ARMv6 "media" instructions (for OMAP2420, i.MX31, etc) Compile-tested. This might not set up the simulator right for the ARMv6 single step support; only BXJ branches though, and docs to support Jazelle branching are non-public (still, sigh). ARMv6 instructions known to be mis-handled by this disassembler include: UMAAL, LDREX, STREX, CPS, SETEND, RFE, SRS, MCRR2, MRRC2 git-svn-id: svn://svn.berlios.de/openocd/trunk@2644 b42882b7-edfa-0310-969c-e2dbd0fdcd60

Those clock issues might explain problems sometimes reported when writing to Stellaris flash banks; they affect write timings. That 12-vs-15 MHz issue is problematic; there's no consolidated doc showing which chips (and revs!) have which internal oscillator speed. It's clear that only older silicon had the faster-and-less-accurate flavor. What's less clear is which chips are "old" like that. Lightly tested, on a DustDevil part. git-svn-id: svn://svn.berlios.de/openocd/trunk@2626 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | - Track whether TRST and/or SRST actually change: * If they're not changing, don't ask the JTAG adapter to do anything! (JTAG TCK/TMS ops might still be used to enter TAP_RESET though.) * Don't change their recorded values until after the adapter says it did so ... so fault paths can't leave corrupt state. * Detect and report jtag_execute_queue() failure mode * Only emit messages saying what really changed; this includes adding an omitted "deasserted TRST" message. * Only apply delays after deasserting SRST/TRST if we *DID* deassert! - Messages say "TLR" not "RESET", to be less confusing; there are many kinds of reset. (Though "TLR" isn't quite ideal either, since it's the name of the TAP state being entered by TMS+TCK or TRST; it's at least non-ambiguous in context.) So the main effect is to do only the work this routine was told to do; and to have debug messaging make more sense. git-svn-id: svn://svn.berlios.de/openocd/trunk@2621 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | 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

It can only be built with the FTD2XX driver. libftdi supports FT2232H/FT4232H since version 0.16 2. A speed value of 0 is used as a RTCK request indicator. This clashes with the valid clock division value 0 that provide the highest fixed clock frequency. 3. The ft2232_speed_div function return the maximum selectable frequency (30MHz) when RTCK is activated. It should return 0. 4. The ft2232_khz function return ERROR_OK when RTCK is requested even for devices lacking RTCK support. It should return ERROR_FAIL so the upper driver layers can detect this and try to fallback to a fixed frequency. 5. FT2232H/FT4232H have a backward compatibility function that divide the clock by 5 to get the same frequency range as FT2232D. There is no code that disable this functionality. I can not find anything about if this is enabled or disabled by default. I think it is safest to actively disable it. git-svn-id: svn://svn.berlios.de/openocd/trunk@2591 b42882b7-edfa-0310-969c-e2dbd0fdcd60
