* 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. We do not want to spam telnet or the log with polling failed messages. Leave that case be w/a comment in a code for now. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* target: Fixed format problem for mdhEdgar Grimberg2010-01-211-1/+1
| | | | | | Fixed format problem for mdh. It needs to display 4 chars. Signed-off-by: Edgar Grimberg <edgar.grimberg@zylin.com>
* target: add check_reset hookØyvind Harboe2010-01-131-0/+36
| | | | | | | Allow targets to run checks post reset. Used to check that e.g. DCC downloads have been enabled. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* *SVF: help/usage updatesDavid Brownell2010-01-081-1/+1
| | | | | | | | | | | | Usage messages should use the same EBNF as the User's Guide; no angle brackets. Be more complete too ... some params were missing. Don't use "&function"; its name is its address. Unrelated: fix typo in one "target.c" usage message. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target misc: help/usage updatesDavid Brownell2010-01-071-122/+155
| | | | | | | | | | | | Provide helptext which was sometimes missing; update some of it to be more accurate. Usage syntax messages have the same EBNF as the User's Guide. Don't use "&function"; functions are like arrays, their address is their name. Shrink some overlong lines; remove some empties. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* streamline and document helptext mode displaysDavid Brownell2010-01-021-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* ARM7_9: Fix segfaultsAntonio Borneo2009-12-301-0/+5
| | | | | | | | | | | Handlers for commands - arm7_9 semihosting <enable | disable> - $_TARGETNAME arp_reset assert 1 didn't check if target has already been examined, and could segfault when using the NULL pointer "arm7_9->eice_cache".

* MinGW build fixesFreddie Chopin2009-12-281-1/+1
| | | | | | | | Print "ssize_t" as "%ld" (+ cast to long) not as "%zu". Official MinGW (gcc 3.4.5) doesn't understand "z" flag. Signed-off-by: Freddie Chopin <freddie_chopin@op.pl> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* target: further shrink Jim-awarenessDavid Brownell2009-12-131-2/+3
| | | | | | | | | | | | | Don't include <helper/jim.h> from target.h ... not everything which touches targets needs to be able to talk to Jim. Plus, most files include this header by another path. Also, switch the affected files to use the classic sequence for #included files: all <framework/headers.h> first, then the "local_headers.h". This helps prevent growth of problematic layering, by minimizing entanglement. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: remove more exit() callsDavid Brownell2009-12-081-1/+2
| | | | | | | | These were all basically "can't happen" cases ... like having state be corrupted by an alpha particle after the previous check for whether a value was in-range. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: remove needless "extern"sDavid Brownell2009-12-081-5/+5
| | | | | | | | | | Most of these happened to be in the target.h file. Some of those are associated with symbols that could be removed at some point ... e.g. NVP_ASSERT/true and its sibling NVP_DEASSERT/false. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: add debug_reason_name()David Brownell2009-12-071-1/+14
| | | | | | | | Provide and use debug_reason_name() instead of expecting targets to call Jim_Nvp_value2name_simple(). Less dependency on Jim, and the code becomes more clear too. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "jtag.h" to <jtag/jtag.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "jtag.h" the following form should be used. #include <jtag/jtag.h> The exception is from .c files in the same directory.
* change #include "time_support.h" to <helper/time_support.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "time_support.h" the following form should be used. #include <helper/time_support.h> The exception is from .c files in the same directory.
* fix 'target init' command registrationZachary T Welch2009-12-021-6/+6
| | | | | The command handler registration was put at the top level, rather than as a subcommand. Move it to where it belongs.
* target: factor init to 'target init'Zachary T Welch2009-12-021-0/+23
| | | | Adds 'target init' command handler, called as part of 'init'.
* target: factor target_init() into piecesZachary T Welch2009-12-021-69/+84
| | | | | Moves body of target initialization loop into a helper function, cleaning up its visual flow in the process.
* target: "mcr" and "mrc" are ARM-specificDavid Brownell2009-12-011-199/+0
| | | | | | | | | | | | | | Switch "mrc" and "mcr" commands to be toplevel ARM operations, as they should initially have been. Correct the usage message for both commands: it matches ARM documentation (as one wants!) instead of reordering them to match the funky mrc() and mcr() method usage (sigh). For Cortex-A8: restore a line that got accidentally dropped, so the secure monitor mode shadow registers will show again. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* do not extern 'interp' from command.cZachary T Welch2009-11-301-4/+7
| | | | | Adds 'interp' field to command_context, chasing the few remaining references to the global variable outside of the command module.
* target: avoid using interp global variableZachary T Welch2009-11-301-9/+10
| | | | | Adds 'interp' to target_event_action structure to avoid using the global variable of the same name.
* explode tcl_target_func into many handlersZachary T Welch2009-11-281-387/+521
| | | | | | | | Eliminate the monolithic tcl_target_func by registering each of its commands using the new chained command registration mechanism. Also chains the target's commands under the CPU command, though these may not work properly without some further modification.
* split jim_target into multiple handlersZachary T Welch2009-11-281-109/+137
| | | | | | | | The 'target' command group was implemented using its own command dispatching, which can be eliminated by using the new chained command registration mechanism. This patch splits the jim_target() function into individual handlers, which makes them to be visible to the help and usage commands. These one-trick handlers are much easier to understand.
* target: uplevel add_{break,watch}point() error checksDavid Brownell2009-11-281-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | In target_type.h it's documented that the target must be halted for add_breakpoint() ... and with slight ambiguity, also for its add_watchpoint() sibling. So rather than verifying that constraint in the CPU drivers, do it in the target_add_{break,watch}point() routines. Add minor paranoia on the remove_*point() paths too: save the return value, and print it out in in the LOG_DEBUG message in case it's nonzero. Note that with some current cores, like all ARMv7 ones I've looked at, there's no technical issue preventing watchpoint or breakpoint add/remove operations on active cores. This model seems deeply wired into OpenOCD though. ALSO: the ARM targets were fairly "good" about enforcing that constraint themselves. The MIPS ones were relied on other code to catch such stuff, but it's not clear such code existed ... keep an eye out for new issues on MIPS.

* target: groundwork for "reset-assert" eventDavid Brownell2009-11-271-2/+17
| | | | | | | | | This defines a "reset-assert" event and a supporting utility routine, and documents both how targets should implement it and how config scripts should use it. Core-specific updates are needed to make this work. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: create and use target_name()David Brownell2009-11-251-16/+19
| | | | | | | | | | | | | Several of the sites now using target_type_name() really ought to be using an instance-specific name. Create a function called target_name(), accessing the instance's own (command) name. Use it in several places that really should be displaying instance-specific names. Also in several places which were already doing so, but which had no wrapper to call. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: target_get_name() --> target_type_name()David Brownell2009-11-251-7/+11
| | | | | | | | | | | | | There are two names that may matter on a per-target basis. One is a per-instance name (for example, "at91sam7s.cpu"). The other is the name of its type (for example, "arm7tdmi"), which is shared among multiple targets. Currently target_get_name() returns the type name, which is misleading and is rarely appropriate for target diagnostics. Rename that as target_type_name(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* add 'testee' target typeZachary T Welch2009-11-251-0/+2
| | | | | | | Alliteration aside, this should provide the final piece of the puzzle for developers that want to get started writing a new target type. In this way, it also seeks to complement the 'dummy' interface driver and 'faux' NOR flash driver.
* add jim_handler to command_registrationZachary T Welch2009-11-241-23/+45
| | | | | | Adding jim_handler field to command_registration allows removing the register_jim helper. All command registrations now go through the register_command{,s}() functions.
* remove target_type register_command callbackZachary T Welch2009-11-241-5/+7
| | | | | | Uses chaining of command_registration structures to eliminate all target_type register_callback routines. Exports the command_handler registration arrays for those target types that are used by others.

* use COMMAND_REGISTER macroZachary T Welch2009-11-241-27/+27

* target: create/use register_cache_invalidate()David Brownell2009-11-191-4/+4
| | | | | | | | | | | | | | | Create a generic register_cache_invalidate(), and use it to replace three all-but-identical core-specific routines: - armv4_5_invalidate_core_regs() - armv7m_invalidate_core_regs - mips32_invalidate_core_regs() too. Make cache->num_regs be unsigned, avoiding various errors. Net code shrink and simplification. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* use COMMAND_PARSE_ON_OFF where appropriateZachary T Welch2009-11-181-14/+5
| | | | Updates all command parsing of "on" and "off" arguments.
* fix regression in md/mw commandsZachary T Welch2009-11-181-4/+2
| | | | | | | The recent migration broke them, the fixes broken them in a new way, but this should restore them to working order. Eliminates the temporary variable, as the CMD_NAME macro can once again be use in routines that increment CMD_ARGV without nasty side-effects.
* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-65/+65
| | | | Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
* command_handler: change 'args' to CMD_ARGVZachary T Welch2009-11-171-58/+58
| | | | | This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
* command_handler: change to 'argc' to CMD_ARGCZachary T Welch2009-11-171-44/+44
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
* target: simplify register get/set opsDavid Brownell2009-11-171-4/+2
| | | | | | | | | | | No need to indirect from registered integers to pointers. Just stash the pointers directly in the register struct, and don't even bother registering. This is a small code shrink, speeds register access just a smidgeon, and gets rid of another rude exit() path. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* fileio: improve API typesZachary T Welch2009-11-161-5/+5
| | | | | | | | | | | | | Use size_t instead of uint32_t when specifying file sizes. Update all consumers up through the layers to use size_t when required. These changes should be safe, but the higher-levels will need to be updated further to receive the intended benefits (i.e. large file support). Add error checking for fileio_read and file_write. Previously, all errors were being silently ignored, so this change might cause some problems for some people in some cases. However, it gives us the chance to handle any errors that do occur at higher-levels, rather than burying our heads in the sand.
* struct fileio: improve member typesZachary T Welch2009-11-161-1/+1
| | | | | | Add const keyword to file url and cast to free(). Make size an ssize_t and chase all format strings that use it.
* rename CEIL as DIV_ROUND_UPZachary T Welch2009-11-161-1/+1
| | | | | Improves the name of this macro, moves it to types.h, and adds a block of Doxygen comments to describe what it does.
* target: don't implicitly include "breakpoint.h"David Brownell2009-11-161-0/+1
| | | | | | | | | | | Most files in the tree seem to have ended up including this, and *quite* needlessly ... only code implementing or using breakpoints actually needs these declarations. So take it out of the header files which included it, and put it in files which use it ... reduce needless interdependencies. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: make "examined" flag be per-targetDavid Brownell2009-11-151-13/+6
| | | | | | | | | | | | | | | | | | Previously this flag was stored in "target_type", so that for example if there were two ARM7TDMI targets in a scan chain, both would claim to have been examined although only the first one actually had its examine() method called. Move this state to where it should have been in the first place, and hide a method that didn't need exposure ... the flag is write-once. Provide some doxygen. The examine() method is confusing, since it isn't separating one-time setup from the after-each-reset stuff. And the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug state alone after reset ... probably more of an issue for trace setup than for watchpoints and breakpoints.

* Invalid command syntax errors with MWW.Dean Glazeski2009-11-141-1/+2
| | | | | This fixes an issue due to the new command handler syntax caused by the mw handler playing with the args pointer before using the CMD_NAME macro. Fix is to move this call above the lines changing args.
