* 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.

* flash/str7x: After reset init the flash is unlockedEdgar Grimberg2010-02-022-3/+23
| | | | | | | | | | | | | | 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
| | | | | | | | The semihosting interface has a strange convention for read/write where the unused amount of buffer must be returned. We failed to return the total buffer size when the local read() call returned 0. Signed-off-by: Nicolas Pitre <nico@marvell.com>
* Test cases ran on v0.4.0-rc1Edgar Grimberg2010-02-015-0/+4557
| | | | | | | | | | | | | Test cases ran on v0.4.0-rc1 for a number of targets: AT91FR40162 LPC2148 SAM7 STR710 STR912 The goal of the testing session was to prove basic functionality of OpenOCD for different targets. Signed-off-by: Edgar Grimberg <edgar.grimberg@zylin.com>
* gdb: restore behavior from 0.3.1 for srst_asserted and power_restoreØyvind Harboe2010-02-012-15/+46
| | | | | | | | srst_asserted and power_restore can now be overriden to do nothing. By default they will "reset init" the targets and halt gdb. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ADIv5: more messaging cleanup, docsDavid Brownell2010-01-311-12/+20
| | | | | | | | | When the TAR cache was explicitly invalidated, don't bother printing it; the actual hardware status is more informative. Provide some doxygen for the MEM-AP setup routine. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* build: fix problems with "struct stat" not being defined under eCosØyvind Harboe2010-01-311-0/+1

* telnet: fix strage blank spaces at beginning of telnet linesØyvind Harboe2010-01-311-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Sometimes we saw two strange blank spaces at the beginning of the telnet lines. progress ogress > This patch fixes this problem: progress progress > The code changes are *reasonably* clean, but perhaps it could be made a bit more elegant, but I didn't want to change things after I finished diagnosis/testing & submitting the patch. The problem was that logging can send the text and the newline separately in two different requests and the telnet code would incorrectly remove the prompt from the end of a line.

* 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5 error checking for Tcl commandsDavid Brownell2010-01-301-1/+17
| | | | | | | | | Reject invalid AP numbers (256+) as Tcl operation parameters. Shrink one of the overlong lines. Add my copyright to the ADIv5 code (multiple contributions). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM ADIv5: fix diagnostics for block writesDavid Brownell2010-01-301-5/+14
| | | | | | They were reporting "read" errors, not "write" errors. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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>
* NOR: cleanup driver declsDavid Brownell2010-01-2918-202/+200

* 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. In helper/system.h, I just defined true and false since clang doesn't have them builtin. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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>
* ARM semihosting: win32 and cygwin fixesSpencer Oliver2010-01-282-16/+32
| | | | | | | | | | | | 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. Added define for systems that do not support O_BINARY. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* 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
| | | | | | | Add space missing after the invalid ACK value. On init, say which AP is being used, and don't assume it's an AHP-AP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* SVF: all content between parentheses is one parametersimon qian2010-01-251-14/+29
| | | | | | | | | | | | | | | | | | | | | | | | | More SVF fixes: * Treat all content between parentheses as part of the same parameter; don't (wrongly) treat whitespace as a delimiter. * Use isspace() to catch that whitespace; it's not all single spaces, newlines etc are also valid. * When parsing bitstrings, strip leading whitespace too. So for example, these are equivalent and should (now) be OK: "TDI( 1234 )" "TDI( 1 2 3 4 )" "TDI(00 12 34 )" "TDI( 00 12 34)" [dbrownell@users.sourceforge.net: comment updates; trivial cleanup] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* core arm11: Silence logs at level 3 if there is no activityEdgar Grimberg2010-01-252-5/+7
| | | | | | | | If the target and openocd are idling, the log should normally be silent at level 3. (Given no verbose logging options.) Signed-off-by: Edgar Grimberg <edgar.grimberg@zylin.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* SVF: insert space before '(' and after ')'simon qian2010-01-231-7/+29
| | | | | | | | | | | | | See http://forum.sparkfun.com/viewtopic.php?p=90983#90983 for discussion; basically, the SVF parser wrongly expects "TDI (123)" but the space is optional and it should accept "TDI(123)" too. In the same way, "TDI(123)TDO(456)" should work too. Rather than update the command parsing, this just makes sure the expected spaces are present.

* EmbeddedICE - fix Feroceon/Dragonite messageDavid Brownell2010-01-221-2/+9
| | | | | | | The breakpoint/watchpoint message was wrong for Feroceon and Dragonite, which have only one working watchpoint unit. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NEWS updatesDavid Brownell2010-01-221-11/+15
| | | | | | | | | | Summarize most ARM11 and Cortex-A8 updates as "acting much more like other ARMs", and mention code sharing. Clarify a few other points, including support for "reset-assert" on all ARMs except Cortex-M (which doesn't exactly need it). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fix breakpoints with GDBDavid Brownell2010-01-221-9/+15
| | | | | | | | | | | This fixes a bug whereby GDB's breakpoints weren't activated. The root cause is a confused interface to resume(). Fix by almost ignoring the "handle breakpoints" parameter; it only seems related to the case of skipping breakpoint-at-PC. Update a few coments to clarify what's happening.

* User's Guide secton on target hardware setupDavid Brownell2010-01-211-1/+81
| | | | | | | | | | | Highlight the needs to properly jumper development boards; to make the OpenOCD configuration match the jumpering; and to have a usable "reset-init" method when debugging early boot code. Specific mention of the "ATX Mode" that seems useful on many i.MX boards, forcing NAND boot. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ADIv5 header cleanup (+ #defines)David Brownell2010-01-211-7/+27
| | | | | | | | | | Update the comments about DP registers and some of the bitfields. Remove inappropriate (and unused) DP_ZERO declaration.

* target: print reason why GDB haltsØyvind Harboe2010-01-211-0/+10
| | | | | | | | | | | If GDB halts unexpectedly, print reason: srst assert or power out detected. If polling fails, then things are a bit trickier.

* Cortex-M3 vector_catch testing supportDavid Brownell2010-01-202-0/+295
| | | | | | | | | | | | | | | The "cm3-ftest.cfg" can be used to verify that OpenOCD handles certain faults correctly: - Test #1: it ignores faults that it wasn't told to catch - Test #2: if vector_catch is told to catch, it catches The "fault.c" generates ASM code to trigger faults, while the config script loads and runs pre-compiled code. This covers most, but not all, of the vector_catch options. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* board configs -- unique names for flash chipsDavid Brownell2010-01-202-8/+6

* gdb_server: correctly report flash sector sizesDavid Brownell2010-01-201-31/+46
| | | | | | | | | | | | | | | Report each region of same-size sectors separately, instead of incorrectly reporting that every sector has the same size. This is a longstanding bug on NOR flash chips with non-uniform sector sizes. It was largely hidden by other bugs in flash handling. When some of those were recently fixed, this one was exposed as a regression on str710.

* ARMV7M: handle bkpt instruction on resume/stepSpencer Oliver2010-01-203-2/+63
| | | | | | | | | | Skip over a bkpt instruction if found on resume/step. Only software breakpoints known to OpenOCD are currently handled.
