* atm920t : fix breakpoints and data cache handlingMarc Pignat2010-02-191-17/+103
| | | | | | | | | Breakpoints did not work because the data cache was not flushed properly. As a bonus add capability to write to memory marked as read only by the MMU, which allows software breakpoints in such memory regions.
* ARM920T scanchain 15 comments/cleanupDavid Brownell2010-02-161-51/+112
| | | | | | | | | | | | | | | | | For folk who don't know the ARM920 JTAG interface very well, the two modes of scan chain 15 access to CP15 are confusing. Make those parts of the ARM920 code less opaque, by: - Adding comments referencing the relevant parts of the TRM, catching up to similar updates in the User's Guide. - Replacing magic numbers in physical access clients with symbolic equivalents. No functional change. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* fix crash with DSP563XXMathias Kuester2010-02-141-0/+25
| | | | | | | | | | | When a DSP563xx-aware GDB asks OpenOCD for target registers, the result should be a GDB with register data ... not an OpenOCD crash. (Note that mainline GDB doesn't currently support this core, so for now, this requires a GDB with FreeScale patches.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NEWS: mention removal of obsolete commandsDavid Brownell2010-02-131-0/+2
| | | | | | | | | | | | | Removed remaining support for various commands, like advice for migrating old-style TAP declarations. The documentation no longer describes them either ... so if users have been delaying config updates, they may need to consult older releases. ALL this stuff has been clearly marked as "do not use" for at least a year now, so anyone still using it hasn't been holding up their end.

* User's Guide: "#" in filesystems names is badDavid Brownell2010-02-101-6/+14
| | | | | | | | Sometimes MS-Windows users try to use filesystem names which include the "#" character. That's generally unwise, since it begins Tcl comments. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

Arm11 code reviewed for further such infinite loop bugs and I couldn't find any more. Xing fingers it's the last one... Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* User's Guide: clarify jtag_rclk adviceDavid Brownell2010-02-101-2/+4
| | | | | | | | | | Not all cores and boards support adaptive clocking, so qualify all advice to use it to depend on core and board support. It's primarily ARM cores which support this; and many of the newer ones (like Cortex-M series) don't. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Re-title Developer's GuideDavid Brownell2010-02-061-2/+2
| | | | | | | | | | | | The Doxygen output was previously titled "OpenOCD Reference Manual", which was quite misleading ... the User's Guide is the reference manual which folk should consult about how to use the software. Just rename it to match how it's been discussed previously, and to bring out its intended audience: developers of this software. As a rule, Doxygen is only for folk who work with the code it documents. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5: doxygenDavid Brownell2010-02-062-32/+138
| | | | | | | | | | | | | | | | | Provide doxygen for many of the public ADIv5 interfaces (i.e. the ones called from Cortex core support code). Add FIXMEs (and a TODO) to help resolve implementation issues which became more apparent when trying to document this code: - Error-prone context-sensitivity (queued/nonqueued) in many procedures. - Procedures that lie by ignoring errors and wrongly claiming success. Also, there was no point in a return from dap_ap_select(); it can't fail, and no caller checks its return status. Clean that up, make it void.

* NOR: User's Guide updatesDavid Brownell2010-02-021-6/+5
| | | | | | | | | | | | Remove long-obsolete text about "erase_check" affecting "flash info" output. Move parts of that text to "protect_check", where it's still relevant; and update the "flash info" description to mention the issue. (This is still awkward. It might be best to make "protect_check" mirror "erase_check" by dumping what it finds, so "flash info" doesn't dump any potentially-stale cache info.)

* tcl/str7x: Reset init unlocks the flashEdgar Grimberg2010-02-022-2/+17
| | | | | | | | | | | For STR7x flash, the device cannot be queried for the protect status. The solution is to remove the protection on reset init. The driver also initialises the sector protect field to unprotected.

| | | | | | | | | | | | | | The default state of the STR7 flash after a reset init is unlocked. The information in the flash driver now reflects this. The information about the lock status cannot be read from the flash chip, so the user is informed that flash info might not contain accurate information.

* ARM semihosting: fix EOF handling with SYS_READNicolas Pitre2010-02-021-1/+1

* Subject: ADIv5: fix more diagnosticsDavid Brownell2010-01-311-9/+16
| | | | | | | | | | | If the MEM-AP cache is invalid, don't display it; just report that invalidity as an error. (This bug has been observed with "mdw 0 32" after just a "reset halt". Some code is being wrongly bypassed...) If it's valid, display that cache at DEBUG level, not ERROR. Also, don't assume it's an AHB-AP; it could be another flavor of MEM-AP.

* ADIv5: cleanup, rename swjdp_transaction_endcheck()David Brownell2010-01-293-34/+43
| | | | | | | | | | | | | | | | Make messages reference "DAP" if they're actually transport-agnostic, or "JTAG-DP" when they're JTAG-specific. Saying SWJ-DP is often wrong (on most Cortex-A8 chips) and is confusing even if correct (since we don't yet support SWD). Rename a JTAG-specific routine to jtagdp_transaction_endcheck() to highlight that it's JTAG-specific, and that identify DAP clients undesirably depending on JTAG. (They will all need to change for SWD support.) Shrink a few overlong lines of code. Copy a comment from code removed in a previous patch (for the ARMv7-M "dap baseaddr" command). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-M: use command handler for "dap baseaddr".David Brownell2010-01-291-30/+1
| | | | | | | | | | Make the ARMv7-M DAP code reuse the command handler for "dap baseaddr". For some reason, this DAP command wasn't converted earlier. This is a code shrink and simplification; it also removes a needless transport dependency on JTAG. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Clang buildfixesAlex Austin2010-01-292-1/+11
| | | | | | | | | Building with clang took a few very small changes. The change to helper/log.h is because clang doesn't like an expression where the result is unused.

* doc clarifications for server flagsDavid Brownell2010-01-282-14/+23
| | | | | | | | | | | | | | | | | | The "-f" is a shortcut for "-c" ... and providing any "-c" options means the "openocd.cfg" file isn't implicitly used. Both the User's Guide and the manual page were weak on these points, which has led to some confusion. Also update the manual page to include highlights of the search path mechanism, including the facts that it exists and that "-s" adds to it. Stop saying only the current directory is involved; the OpenOCD script library is quite significant. (Missing: complete manpage coverage of the search path, including a FILES section listing all components and saying where the script library is found.)

* ARM: reference DPM defn from v6/v7 arch specDavid Brownell2010-01-281-0/+6
| | | | | | | | The term "DPM" is probably not well known ("Device Power Management"?), so identify its source in the current ARM architecture specification. It's relevant to ARMv6, ARMv7-A, and ARMv7-R ... but not "M" profiles. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | | | Cygwin would fail to reopen a previously written file if the mode is not given. Simplified converting the open flags and made sure the win32 O_BINARY bit is set.

* ARM semihosting: fix writing to stdoutSpencer Oliver2010-01-282-8/+6
| | | | | | | | SYS_FLEN would be called before a write on a descriptor to check its size. Currently lseek would fail with -1 when given the stdout/stderr descriptor. Changing to use fstat seems to be the standard way of handling this. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* Cortex-M3: report lockup, and recoverDavid Brownell2010-01-271-0/+15
| | | | | | | | | | | | ARMv7-M defines a "lockup" state that's entered in certain double fault sequences which can't be recovered from without external help. OpenOCD has previously ignored this. Issue a diagnostic saying the chip has locked up, and force exit from this state by halting the core. It's not clear this is the best way to handle lockup; but there should now be less confusion.

* ARM ADIv5: messaging tweaksDavid Brownell2010-01-271-2/+5
