* 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>
* User's guide: mention lpc2000 checksum issueDavid Brownell2010-01-201-4/+10
| | | | | | | | Folk almost certainly want to have OpenOCD compute the checksum when they modify the vector table. However, that almost guarantees that "verify_image" will fail. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* nand flash support for s3c64xxPeter Korsgaard2010-01-141-1/+2
| | | | | | | | | | | | Identical to the existing 2412/2443 support except for the base address and NFCONF value (bit 2 is reserved and should be written as 1 ref UM). Tested on a s3c6410 board, but controller is identical in 6400/6410 except for 8bit MLC ECC support in 6410 which isn't supported by the driver.

* User's Guide updatesDavid Brownell2010-01-131-23/+88
| | | | | | | | | | | | | | | | Capture various bits of useful information that have come up on the list but haven't yet gotten into the documentation: - Watchdog timers firing during JTAG debug need attention; - Some chips have special registers to help JTAG debug; - Cortex-M3 stepping example with IRQs and maskisr; - Clarifications re adaptive clocking: not all ARMs do it, and explain it a bit better.

* NOR: add optional "flash erase_address" sector paddingDavid Brownell2010-01-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a NOR flash mechanism where erase_address ranges can be padded out to sector boundaries, triggering a diagnostic: > flash erase_address 0x0001f980 16 address range 0x0001f980 .. 0x0001f98f is not sector-aligned Command handler execution failed in procedure 'flash' called at file "command.c", line 647 called at file "command.c", line 361 > > flash erase_address pad 0x0001f980 16 Adding extra erase range, 0x0001f800 to 0x0001f97f Adding extra erase range, 0x0001f990 to 0x0001fbff erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s) > This addresses what would otherwise be something of a functional regression. An earlier version of the interface had a dangerous problem: it would silently erase data outside the range it was told to erase. Fixing that bug turned up some folk who relied on that unsafe behavior. (The classic problem with interface bugs!) Now they can get that behavior again. If they really need it, just specify "pad".

* FreeBSD build fixesDavid Brownell2010-01-101-3/+4
| | | | | | | | | | Based on notes from Tomek Cedro <tomek.cedro@gmail.com> and Steve Franks <bahamasfranks@gmail.com>.

* parport (mostly) doc fixesDavid Brownell2010-01-091-13/+19
| | | | | | | | | | | | | | | | | | | The "parport_port" commands generally don't *require* a port_number; they're of the "apply any parameter, then print result" variety. Update the User's Guide accordingly. Some of those commands are intended to be write-once: parport_port, and parport_cable. Say so. Use proper EBNF for the parport_write_on_exit parameter. Parport address 0xc8b8 is evidently mutant. Say so in the "parport.cfg" file, to avoid breaking anyone with that mutant config. But update the User's Guide to include a sane example for the LP2 port. Finally document the "presto_serial" command. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* src/flash/nor: usage/help/doc updatesDavid Brownell2010-01-091-2/+2
| | | | | | | | | | | | | Make "usage" messages use the same EBNF as the User's Guide; no angle brackets. Improve and correct various helptexts. Don't use "&function"; a function's name is its address. Remove a couple instances of pointless whitespace; shrink a few overlong lines; fix some bad indents. Add TODO list entry re full support for NAND/NOR bank names. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* src/server: usage/help/doc updatesDavid Brownell2010-01-091-4/+4
| | | | | | | | | | | | | | | Make "usage" messages use the same EBNF as the User's Guide; no angle brackets. Improve and correct various helptexts. Specifically for the port commands, clarify that the number is optional, and omitting it causes the current number to be displayed. Don't use "&function"; a function's name is its address. Remove a couple instances of pointless whitespace; shrink a few overlong lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NAND: help/usage/doc updatesDavid Brownell2010-01-081-3/+3
| | | | | | | | | | | | | | Usage messages should use the same EBNF as the User's Guide; no angle brackets. Be more complete too ... some params were missing. Improve and correct various helptexts. Make user's guide refer to the NAND "driver" name, not the controller name; that's a bit more precise. Don't use "&function"; its name is its address. Line up struct initializers properly. Remove some blank lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Coexist with quilt: rename PATCHES --> PATCHES.txtDavid Brownell2010-01-081-1/+1
| | | | | | | | | | The issues is on Win32, which ignores case in filesystem and thus doesn't tolerate the quilt "patches" directory. Rename, and add "patches" to .gitignore so that developers can choose to use quilt for local patch management. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM720: help/usage updatesDavid Brownell2010-01-071-2/+10
| | | | | | | | | | | | | Deprecate the "pass an instruction opcode" flavor of cp15 access in favor of the "arm mcr ..." and "arm mrc ..." commands, which offer fewer ways to break things. Use the same EBNF syntax in the code as for the user's guide. Update User's Guide to say where to find those magic values (which table in the ARM920 TRM).

| | | | | | | | | | | | | | | | | Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Uupdate some helptext to be more accurate. Fix the User's Guide in a few places to be more consistent (mostly to use brackets not parentheses) and to recognize that parameter may be entirely optional (in which case the command just displays output, and changes nothing). Also reference NXP, not Philips, for LPC chips. Don't use "&function"; functions are like arrays, their address is their name. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Don't use "&function"; functions are like arrays, their address is their name. Shrink some overlong lines, remove some empties. Add a couple comments about things that should change: those extra TCK cycles for MEM-AP reads are in the wrong place (that might explain some problems we've seen); the DAP command tables should be shared, not copied.

* streamline and document helptext mode displaysDavid Brownell2010-01-021-3/+10
| | | | | | | | | | | | | | | | | | | Most commands are usable only at runtime; so don't bother saying that, it's noise. Moreover, tokens like EXEC are cryptic. Be more clear: highlight only the commands which may (also) be used during the config stage, thus matching the docs more closely. There are - Configuration commands (per documentation) - And also some commands that valid at *any* time. Update the docs to note that "help" now shows this mode info. This also highlighted a few mistakes in command configuration, mostly commands listed as "valid at any time" which shouldn't have been. This just fixes ones I noted when sanity testing.

* Fix Luminary FT2232 layout docs/configsDavid Brownell2009-12-281-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of this patch updates documentation and comments for various Luminary boards, supporting two bug fixes by helping to make sense of the current mess: - Recent rev C lm3s811 eval boards didn't work. They must use the ICDI layout, which sets up some signals that the older boards didn't need. This is actually safe and appropriate for *all* recent boards ... so just make "luminary.cfg" use the ICDI layout. - "luminary-lm3s811.cfg", was previously unusable! No VID/PID; and the wrong vendor string. Make it work, but reserve it for older boards where the ICDI layout is wrong. - Default the LM3748 eval board to "luminary.cfg", like the other boards. If someone uses an external JTAG adapter, all boards will use the same workaround (override that default). The difference between the two FT2232 layouts is that eventually the EVB layout will fail cleanly when asked to enable SWO trace, but the ICDI layout will as cleanly be able to enable it. Folk using "luminary.cfg" with Rev B boards won't see anything going wrong until SWO support is (someday) added. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NOR: make flash_write_unlock() pad to sector endDavid Brownell2009-12-271-2/+23
| | | | | | | | | | | | | | Resolve a regression when using newish automagic "write_image" modes, by always padding to the end of affected sectors. Also document some issues associated with those automagic options, in the User's Guide and also some related code comments. We might need similar padding at the *beginning* of some sectors, but this is a minimalist fix for the problems which have currently been reported (plus doc updates).

* AT91SAM9 NAND flash driver.Dean Glazeski2009-12-191-0/+35
| | | | | | | | | | This creates the TCL interface for configuring an AT91SAM9 NAND flash controller and implements the necessary functions to correctly work with a NAND flash device connected to the chip. This includes updates to the driver list and the Makefile.am to support building the driver and also houses the documentation update in openocd.texi.

* ETM: add "etm trigger_debug" commandDavid Brownell2009-12-191-0/+11
| | | | | | | | | | | | | | | | In conjunction with manual register setup, this lets the ETM trigger cause entry to debug state. It should make it easier to test and bugfix the ETM code, by enabling non-trace usage and isolating bugs specific to thef ETM support. (One current issue being that trace data collection using the ETB doesn't yet behave.) For example, many ARM9 cores with an ETM should be able to implement four more (simple) breakpoints and two more (simple) watchpoints than the EmbeddedICE supports. Or, they should be able to support complex breakpoints, incorporating ETM sequencer, counters, and/or subroutine entry/exit criteria int criteria used to trigger debug entry. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ETM trigger_percent becomes an ETB commandDavid Brownell2009-12-191-22/+22
| | | | | | | | This command was misplaced; it's not generic to all traceport drivers, only the ETB supports this kind of configuration. So move it, and update the relevant documentation. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* JTAG: shrink "scan_chain" outputDavid Brownell2009-12-161-7/+7
| | | | | | | | | | Tweak the "scan_chain" output by removing column separators. Also remove the "current instruction" state ... which changes constantly. Now its style resembles the "targets" output, and can even fit on one line in standard terminals and in the PDF docs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* jtag: add '-ignore-version' optionDavid Brownell2009-12-141-0/+6
| | | | | | | | | | Add a "-ignore-version" to "jtag newtap" which makes the IDCODE comparison logic optionally ignore version differences. Update the "scan_chain" command to illustrate this by showing the "*" character instead of the (ignored) version nibble. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: list number of HW breakpoints/watchpointsDavid Brownell2009-12-071-7/+37
| | | | | | | | | | | | | | | When starting up, say how many hardware breakpoints and watchpoints are available on various targets. This makes it easier to tell GDB how many of those resources exist. Its remote protocol currently has no way to ask OpenOCD for that information, so it must configured by hand (or not at all). Update the docs to mention this; remove obsolete "don't do this" info. Presentation of GDB setup information is still a mess, but at least it calls out the three components that need setup. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* User's Guide: add quickie setup notesDavid Brownell2009-12-071-2/+41
| | | | | | | | | | | | | Add a brief "setup with no customization" note showing the how easily things can work if standard OpenOCD config scripts already exist. We've had some new users comment that this information is needlessly hard to find, so that starting to use OpenOCD is more difficult than it should be. Plus describe a few other issues that come up when setting up an OpenOCD server. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* basic ARM semihosting supportNicolas Pitre2009-12-031-0/+11
| | | | | | | | | | | | | | | | | | | | Semihosting enables code running on an ARM target to use the I/O facilities on the host computer. The target application must be linked against a library that forwards operation requests by using the SVC instruction that is trapped at the Supervisor Call vector by the debugger. The "hosted" library version provided with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example. This is currently available for ARM9 processors, but any ARM variant should be able to support this with little additional work. Tested using binaries compiled with Sourcery G++ Lite 2009q1-161 and ARM RVCT 3.0.

* ARM7/ARM9: remove old "debug commands"David Brownell2009-11-201-52/+35
| | | | | | | | | | | | | | | Remove two commands that were documented as "debug commands" and where "you probably don't want to use this". We never intended to support them, and at least one problem report boiled down to using this when it shouldn't have been used. Update the docs on the existing register commands to talk a bit more about register access and cache behavior. (Those debug commands existed largely to *bypass* the cache.) And fix some minor doc goofs that snuck in with recent changes, renaming "armv4_5" as "arm" and "arm9tdmi" as "arm9". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | | | | | | | Rename the "armv4_5" command prefix to straight "arm" so it makes more sense for newer cores. Add a simple compatibility script.

* Add 'nand verify' commandZachary T Welch2009-11-161-0/+26
| | | | | | | | | | | Add the 'nand verify' command to perform a dump and fake-write simultaneously, checking the read bits against those generated by the write process. Appropriate user documentation for this command has been added to the user guide as well. The algorithm presently makes a relatively naive comparison. Some chips that use ECC may not verify correctly using this implementation, but the new documentation provides details about this limitation.
* ETM: start support for ETMv2+David Brownell2009-11-121-3/+15
| | | | | | | | | | | | | | | | | ARM11 and newer cores include updated ETM modules. Recognize their version codes and some key config differences. Sanity checked on an OMAP2, with an ETM11RV r0p1 (ETMv3.1). This still handles only scan chain 6, with at most 128 registers. Newer cores (mostly, Cortex) will need to use the DAP instead. Note that the newer ETM modules don't quite fit the quirky config model of the older ones ... having more port widths is easy, but the modes aren't the same. That still needs to change.

* target: MMU-aware init for memory read/writeDavid Brownell2009-11-101-5/+9
| | | | | | | | | | | | | | | | | | Start switching MMU handling over to a more sensible scheme. Having an mmu() method enables MMU-aware behaviors. Not having one kicks in simpler ones, with no distinction between virtual and physical addresses. Currently only a handful of targets have methods to read/write physical memory: just arm720, arm920, and arm926. They should all initialize OK now, but the arm*20 parts don't do the "extra" stuff arm926 does (which should arguably be target-generic). Also simplify how target_init() loops over all targets by making it be a normal "for" loop, instead of scattering its three parts to the four winds.
