* Add macro for parsing numeric command arguments.Zachary T Welch2009-11-051-0/+21
| | | | | | | | This helper eliminates significant amount of redundant code in command handler functions throughout the system. It wraps the lower-level parse_* macros to implement a policy for reporting parse errors to the active command context (cmd_ctx). If errors do occur, this macro causes the calling function to abort with the proper return code.

* watchpoint_add() cleanupDavid Brownell2009-11-054-32/+40
| | | | | | | | | | | | Fail watchpoint_add() if it's the same address but the parameters are different ... don't just assume having the same address means the same watchpoint! (Note that overlapping watchpoints aren't detected...) Handle unrecognized return codes more sanely; don't exit()! And describe command params right.

* Cortex-M3: expose most DWT registersDavid Brownell2009-11-052-21/+144
| | | | | | | | | | | | | | | | | | | | | | | Expose most DWT registers via Tcl; there are a few more, but those are mostly for profiling along with the ITM. Having this set available enables operations which aren't possible with just the standard watchpoint operations. The cycle counter may be interesting. Turn it on after reset by setting the LSB of the dwt_ctrl register, and it counts CPU clocks. You can program the comparator 0 watchpoint to trigger on a given cycle count, rather than a data address. Likewise, comparator 1 may be able to match data values given address matches from one or two other comparators. (Not all hardware supports this capability though; try it. That is something the standard watchpoint methods should eventually handle, for the single address case.) Minor cleanup: remove needless functional indirection for exposing the v7m architctural registers. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Cortex-M3: minor cleanupDavid Brownell2009-11-052-16/+4
| | | | | | | | | | | There's no reason to read which interrupts are enabled from the NVIC; that state isn't used. Plus, it's highly dynamic since firmware can change it at any time; remove the support for those state records. Remove duplicate definition of DWT_CTRL address; shrink a line.

* Cortex-M3: DWT cleanup/fixesDavid Brownell2009-11-051-56/+115
| | | | | | | | | | | | | Fix the watchpoint error checks, and do them in add(), not later in set() when it's mostly too late. Support the full range of watchpoint sizes (1 to 32K bytes each), and check alignments. Minor cleanup of DWT access: shrink lines, use "+" for address calculations, comment a few issues. Add debug message reporting DWT capabilities, matching the message for FBP, and some minor code and spec review comments. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | Add Doxygen for the exported ARMv7-M interfaces. Make the non-exported stuff static. Remove functions and data which are now observably unused. Add comment about a small speedup that the run_algorithm() logic could use. Shrink a few too-long lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* arm920t: memory writes were broken when MMU was disabledØyvind Harboe2009-11-031-11/+10
| | | | | | | | | | | To support breakpoints, flush data cache line and invalidate instruction cache when 4 and 2 byte words are written. The previous code was trying to write directly to the physical memory, which was buggy and had a number of other situations that were not handled.

| | | | | | | | | | | | | | | | Fixed bug: if virtual address for working memory was not specified and MMU was enabled, then address 0 would be used. Require working address to be specified for both MMU enabled and disabled case. For some completely inexplicable reason this fixes the regression in svn 2646 for flash write in arm926ejs target.

* XSVF: bugfix handling state pathsDavid Brownell2009-10-291-15/+100
| | | | | | | | | | | | | | | | | | | | | | | Implement XSVF support for detailed state path transitions, by collecting sequences of XSTATE transitions into paths and then calling pathmove(). It seems that the Xilinx tools want to force state-by-state transitions instead of relying on the standardized SVF paths. Like maybe there are XSVF tools not implementing SVF paths, which are all that we support using svf_statemove(). So from IRPAUSE, instead of just issuing "XSTATE DRPAUSE" they will issue XSTATES for each intermediate state: first IREXIT2, then IRUPDATE, DRSELECT, DRCAPTURE, DREXIT1, and finally DRPAUSE. This works now. Handling of paths that go *through* reset is a trifle dodgey, but it should be safe.

* Cortex-M3: remove exports and forward declsDavid Brownell2009-10-282-189/+144
| | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Make most functions static, and fix some line-too-long issues. Delete some now-obviously-unused code.

* ARM926: remove exports and forward declsDavid Brownell2009-10-281-122/+127
| | | | | | | | | | | | | Unneeded exports cause confusion about the module interfaces. Only the Feroceon code builds on this, so only routines it reuses should be public.. Make most remaining functions static, and fix some of the line-too-long issues. The forward decls are just code clutter; move their references later, after the normal declarations. Turns out we don't need even one forward declaration in this file. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* bugfix: stack corruption loading IHex imagesFranck HÉRÉSON2009-10-282-1/+22
| | | | | | | | | | | | The Hex parser uses a fixed number of sections. When the number of sections in the file is greater than that, the stack get corrupted and a CHECKSUM ERROR is detected which is very confusing. This checks the number of sections read, and increases IMAGE_MAX_SECTIONS so it works on my file. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: fix single-step of Thumb unconditional branchNicolas Pitre2009-10-271-2/+2

* ARM: fix target address when disassembling Thumb BLXNicolas Pitre2009-10-271-0/+1
| | | | | | | | A Thumb BLX instruction is branching to ARM code, and therefore the first 2 bits of the target address must be cleared. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Signalyzer: H2 and H4 supportOleg Seiljus2009-10-271-0/+809

* ARM: fix Thumb mode handling when single-stepping register based branch insnsNicolas Pitre2009-10-261-22/+33
| | | | | | | | | | | | | | | | | | | Currently, OpenOCD is always caching the PC value without the T bit. This means that assignment to the PC register must clear that bit and set the processor state to Thumb when it is set. And when the PC register value is transferred to another register or stored into memory then the T bit must be restored. Discussion: It is arguable if OpenOCd should have preserved the original PC value which would have greatly simplified this code. The processor state could then be obtained simply by getting at bit 0 of the PC. This however would require special handling elsewhere instead since the T bit is not always relevant (like when PC is used with ALU insns or as an index with some addressing modes). It is unclear which way would be simpler in the end. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: allow proper single stepping of Thumb BL and BLX instructionsNicolas Pitre2009-10-261-0/+12
| | | | | | | | | | | | | | Whenever an unconditional branch with the H bits set to 0b10 is met, the offset must be combined with the offset from the following opcode and not ignored like it is now. A comment in evaluate_b_bl_blx_thumb() suggests that the Thumb2 decoder would be a simpler solution. That might be true when single-stepping of Thumb2 code is implemented. But for now this appears to be the simplest solution to fix Thumb1 support. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: call thumb_pass_branch_condition() only for actual branch opcodesNicolas Pitre2009-10-261-8/+6
| | | | | | | | | | | | | | Calling it first with every opcodes and then testing if the opcode was indeed a branch instruction is wasteful and rather strange. If ever thumb_pass_branch_condition() has side effects (say, like printing a debugging traces) then the result would be garbage for most Thumb instructions which have no condition code. While at it, let's make the nearby code more readable by reducing some of the redundant brace noise and reworking the error handling construct.

* JTAG: simple autoprobingDavid Brownell2009-10-261-12/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic autoprobing support for the JTAG scan chains which cooperate. To use, you can invoke OpenOCD with just: - interface spec: "-f interface/...cfg" - possibly with "-c 'reset_config ...'" for SRST/TRST - possibly with "-c 'jtag_khz ...'" for the JTAG clock Then set up config files matching the reported TAPs. It doesn't declare targets ... just TAPs. So facilities above the JTAG and SVF/XSVF levels won't be available without a real config; this is almost purely a way to generate diagnostics. Autoprobe was successful with most boards I tested, except ones incorporating C55x DSPs (which don't cooperate with this scheme for IR length autodetection). Here's what one multi-TAP chip reported, with the "Warn:" prefixes removed: clock speed 500 kHz There are no enabled taps. AUTO PROBING MIGHT NOT WORK!! AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x2b900f0f ..." AUTO auto1.tap - use "jtag newtap auto1 tap -expected-id 0x07926001 ..." AUTO auto2.tap - use "jtag newtap auto2 tap -expected-id 0x0b73b02f ..." AUTO auto0.tap - use "... -irlen 4" AUTO auto1.tap - use "... -irlen 4" AUTO auto2.tap - use "... -irlen 6" no gdb ports allocated as no target has been specified The patch tweaks IR setup a bit, so we can represent TAPs with undeclared IR length.
