| | | | | | | | | | | | | | | | | | | | | lean up some loose ends with the ARM disassembler - Add a header comment describing its current state and uses and referencing the now-generally-available V7 arch spec - Support some mode switch instructions: * Thumb to Jazelle (BXJ) * Thumb to ThumbEE (ENTERX) * ThumbEE to Thumb (LEAVEX) - Improve that recent warning fix (and associated whitespace goof) - Declare the rest of the internal code and data "static". A compiler may use this, and it helps clarify the scope of these routines (e.g. what changes to them could affect). git-svn-id: svn://svn.berlios.de/openocd/trunk@2675 b42882b7-edfa-0310-969c-e2dbd0fdcd60

* David Brownelloharboe2009-09-036-74/+191
| | | | | | | | | | | | | | | | Abstract the orion_nand_fast_block_write() routine into a separate routine -- arm_nandwrite() -- so that other ARM cores can reuse it. Have davinci_nand do so. This faster than byte-at-a-time ops by a factor of three (!), even given the slowish interactions to support hardware ECC (1-bit flavor in that test) each 512 bytes; those could be read more efficiently by on-chip code. NOTE that until there's a generic "ARM algorithm" structure, this can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8) cores, though the downloaded code itself would work just fine there. git-svn-id: svn://svn.berlios.de/openocd/trunk@2663 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.

| | | | | | | | | | | | | | | | | | | | | | | - 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
