| 10:26.52 | iperry | any openocd devs around? i'm having a curious problem with a cortex m3 and breakpoints |
| 10:27.21 | iperry | the target nearly immediately halts after a reset |
| 10:27.42 | iperry | if i debug it with gdb, it appears the debug registers are filled with some junk data |
| 10:28.04 | iperry | gdb can clear the debug registers (clearing the breakpoint), and then execution continues as normal |
| 10:40.18 | roxfan2 | you mean you don't want it to halt? |
| 10:40.26 | iperry | no, |
| 10:40.44 | iperry | it shouldn't be halting, i haven't set any breakpoints yet |
| 10:40.59 | roxfan | check the config, many of deault ones specify halt after reset |
| 10:41.24 | roxfan | otherwise enable debug tracing, maybe you can see some clues |
| 10:41.41 | iperry | which config option do i look for? |
| 10:41.50 | iperry | i have reset_config set to trst_and_srst |
| 10:42.11 | roxfan | no, that one comes later |
| 10:42.33 | roxfan | let me see if i can find it... |
| 10:43.04 | iperry | thanks |
| 10:46.10 | iperry | actually, looks like somebody else is having exactly the problem i'm having: |
| 10:46.10 | iperry | http://forum.sparkfun.com/viewtopic.php?t=14603 |
| 10:47.44 | roxfan | hmm what if you do "reset run" instead of just "reset"? |
| 10:48.04 | iperry | same thing |
| 10:48.17 | roxfan | looks like a bug then... |
| 10:48.29 | roxfan | do you get the same log? |
| 10:48.43 | iperry | let me check |
| 10:49.47 | iperry | it would appear so |
| 10:50.11 | iperry | the PC at which it halts at is somewhat variable |
| 10:50.24 | iperry | within a couple of instructions |
| 10:50.29 | roxfan | can you try increasing debug level? |
| 10:50.38 | iperry | i'm at -d 3 |
| 10:50.46 | iperry | Debug: 917 88269 cortex_m3.c:400 cortex_m3_debug_entry(): entered debug state in core mode: Thread at PC 0x2eee, target->state: halted |

| 10:50.54 | iperry | User : 924 88269 command.c:494 command_run_line(): |
| 10:52.47 | roxfan | as a workaround you could try adding a halt event handler |
| 10:53.16 | roxfan | http://openocd.berlios.de/doc/Target-Configuration.html |
| 10:53.50 | iperry | have them clear out the debug registers and do a reset? |
| 10:54.33 | roxfan | just continue might work too |
| 10:58.23 | iperry | okay, that looks okay |
| 10:58.26 | iperry | i'll use that in the meantime |
| 10:58.41 | iperry | any suggestions to dig into this further? i guess i'll file a bug |
| 11:00.01 | roxfan | yes, better post to ML |
| 11:00.19 | roxfan | i think a few people there were using m3 |
| 11:00.36 | roxfan | you can also try debugging it yourself :) |
| 11:02.18 | iperry | :P |
