* at91cap7a-stk-sdram.cfg: faster resetØyvind Harboe2010-08-121-5/+5
| | | | | | crank up JTAG speed as soon as clocks are set up. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: fix handling of 'tap enable' errorThomas Koeller2010-08-121-2/+2
| | | | | | | | if a tap could not be _enabled_, the error message was 'failed to disable tap'. Fixed that. Also, display the failing tap's name. Signed-off-by: Thomas Koeller <thomas.koeller@baslerweb.com>
* DM36x: Set OSCDIV dividerThomas Koeller2010-08-121-0/+7
| | | | | | The ability to set up the OSCDIV divider was missing. Signed-off-by: Thomas Koeller <thomas.koeller@baslerweb.com>
* DM36x: Disable unused SYSCLKsThomas Koeller2010-08-121-1/+20
| | | | | | | | Clear the enable bits for all clocks that are not set explicitly. This is done to increase robustness by removing pre-existing state. Signed-off-by: Thomas Koeller <thomas.koeller@baslerweb.com>
* DM36x: Use enable bit for PLL pre-dividerThomas Koeller2010-08-121-1/+1
| | | | | | | The PLL pre- and postdividers seem to have enable bits, although these are not mentioned in the chip documentation. Signed-off-by: Thomas Koeller <thomas.koeller@baslerweb.com>
* str9x: faster flash erase of entire chipFredrik Hederstierna2010-08-121-6/+23
| | | | | | | The patch improves flash erase for STR9x in case of a full bank erase. Then the chip erase command is used instead which improves speed significantly. Also I think it might help if e.g. STR912 enters some state where flash banks are locked, and a chip erase command is the key for unlocking the flash.
* tcl: remove silly ocd_ prefix to array2mem and mem2arrayØyvind Harboe2010-08-119-20/+20
| | | | | | | | ocd_ prefix is used internally in OpenOCD as a kludge more or less to deal with the two kinds of commands that OpenOCD has. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* board: added at91cap7a stk w/sdram config scriptsØyvind Harboe2010-08-111-0/+165
| | | | | | | The strange thing here with this board is that 16MHz kinda works, but only 2MHz is really stable. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* debug: use assert's when approperiateØyvind Harboe2010-08-112-4/+2

* cfg: add omapl138 support and da850evm preliminary supportBen Gardiner2010-08-102-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the omapl138 target and preliminary support for the da850evm. The target cfg file is based on the icepick routing done by the target/ti_dm6446.cfg file. I have performed limited testing with this setup. I am posting this patch in the interest of sharing cfg files and in the hopes that the experts on this list can correct errors I have made or point out enhancements. The testing I have performed is debugging uboot with gdb where I also use the following local.cfg and gdbinit files. Debugging appears to work in so much as 'ni' works. local.cfg: gdb_memory_map disable gdbinit: target remote localhost:3333 set remote hardware-breakpoint-limit 2 set remote hardware-watchpoint-limit 2 monitor poll on Comments welcome. Best Regards, Ben Gardiner
* arm7/9: fix "reset run + halt"Øyvind Harboe2010-08-092-11/+27
| | | | | | | | | | | | | | | | if polling is off, then "reset run + halt" would fail since halt incorrectly assumed the target was in the reset state as it is the internal poll implementation that moves the sw tracking of the target state out of the reset state. To reproduce: > reset run; halt JTAG tap: zy1000.cpu tap/device found: 0x1f0f0f0f (mfg: 0x787, part: 0xf0f0, ver: 0x1) BUG: arm7/9 does not support halt during reset.

* target: if polling fails, back offØyvind Harboe2010-08-091-8/+29
| | | | | | | | | | | | back-off algorithm for polling. Double polling interval up to 5000ms when it fails. when polling succeeds, reset backoff. This avoids flooding logs(as much) when working with conditions where the target polling will fail. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* Luminary-icdi comment updateDavid Brownell2010-08-031-0/+4

* xscale documentation: vector table handlingMike Dunn2010-08-021-4/+22
| | | | | | | | | | | | | | | | | | | | | | | Hi everyone. I noticed some incorrect information in the user manual regarding how the vector table is handled on the xscale, so for your consideration, here's a short patch that corrects it, and adds a little more detail I thought might be helpful. The documentation states that OpenOCD does not attempt to synchronize the vector tables in memory with those stored in the "mini instruction cache". In fact, on each resume it does copy from memory to the cache all entries in the high and low tables that were not previously defined using the 'xscale vector_table' command. (In src/target/xscale.c, see xscale_update_vectors(), which is invoked by xscale_resume().) I take advantage of this during Linux boot-up. The extra detail describes in general terms how I do this. Corrections, comments are of course gratefully received. Thanks, Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com>

* Remove srst_pulls_trst from LPC2148 targetPeter Stuge2010-08-011-1/+1
| | | | | | | | | srst_pulls_trst is only true on some (broken) LPC2148 boards, a fact which is already documented in doc/openocd.texi, so it shouldn't be set unconditionally in the target tcl. This patch was needed to reflash when an Abort exception occured very early after reset, before OpenOCD tried to halt the CPU.
* stellaris flash comment updateDavid Brownell2010-08-011-1/+1
| | | | | | | | This flash driver works on more than just two chips. (Though it does need work still, e.g. to protect more than 64K. (On non-'3748-A0 chips where errata allow that.)) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* flash: remove algorithm exit_point address for supported targetsSpencer Oliver2010-07-204-5/+4
