| 15:04.56 | vloewis | Hi. Ich könnte die Unterstützung eines openocd-Gurus gebrauchen. Bin ich hier richtig? |
| 15:07.12 | vloewis | Ok. Ist hier jemand? |
| 15:29.05 | mib_iq2t65 | What does an openocd guru know, that you need ? |
| 15:31.59 | vloewis | well i need some help with the setup |
| 15:32.36 | vloewis | i am using a aduc7020, downloaded yagarto installed everything, |
| 15:32.56 | vloewis | and the debugger doesn't work |
| 15:33.44 | vloewis | i took me a while to figure out a cfg-file, which at least starts up without any complaints, |
| 15:34.44 | vloewis | i can set/rest any registers and watch the leds of my demo-board behaving accordingly, |
| 15:35.14 | vloewis | but when i try to step through code ... zip. |
| 15:36.38 | vloewis | all examples that i've found so far contain commands, which cause errors |
| 15:37.31 | vloewis | now when i try to single step through code using a telnet console i get: |
| 15:37.48 | vloewis | "should never reach this point" |
| 15:38.46 | vloewis | "BUG: couldn't calculate PC of next instruction, current opcode was 0x4c000a0d |
| 15:38.54 | vloewis | "etc. ..." |
| 15:39.14 | vloewis | does anyone have any ideas what to do about it? |
| 15:42.45 | vloewis | well just got a call. friend of mine crashed his car. 'll try again later |

| 20:54.55 | maluta | Hi, is it possible (with openocd) to use parallel JTAG to communicate with AVR32AP7000 and flash my memory? |
| 20:57.10 | zwelch | maluta: avr support was just recently added, but i think it might be possible |
| 20:58.21 | maluta | zwelch, I saw a recent thread from February (https://lists.berlios.de/pipermail/openocd-development/2009-February/004707.html) |
| 20:58.26 | zwelch | if you join the developer mailing list and post a question, i would bet that the developer that added it will provide a definitive answer |
| 20:58.37 | maluta | zwelch, ok |

| 22:10.22 | RavenClaw_78 | hi, i try to modify a gpio bit using the memory view in eclipse to switch on a led on the LM3S8962_EVAL board. its connected via openocd r1468. But when i set the value to 1, the led flashes for parts of a second and just ends up with everything set to 0. does someone have an idea why this happens ? |
| 22:25.41 | zwelch | RavenClaw_78: have you tried checking out the latest svn trunk? also, you don't mention the jtag interface that you're using |
| 22:29.43 | RavenClaw_78 | zwelch: the board is connected via usb over an ftdi chip. I'm using the luminary.cfg interface config and the lm3s6965.cfg target ...its not the exact target but was the closest one and debugging and reading memory works. No, didn't tried the latest from svn |
| 22:31.19 | zwelch | okay. i am not experienced enough to give you a meaningful answer, so the best i can recommend would be to join the developer mailing list and post your question there with plenty of details |
| 22:32.11 | zwelch | still, we will be curious to hear the results from the latest revisions, as there has been a number of changes to the system recently that may improve certain situations and operations |
| 22:32.36 | zwelch | (though i admit it's still unclear when and which ones ;) ) |
| 22:35.01 | RavenClaw_78 | then i'll try to build the latest, hopefully more succesfully than last try... |
| 22:37.03 | RavenClaw_78 | whats still confuses me is if i write a 0x1 then the light flashes ...also with 0x3 ...but not with 0x2 ...->led is on pin0 ...so it must get through somehow but than vanishes again |
| 22:45.44 | mib_gj3svv | there seems to be a interrupt routine working in the background or something |
| 22:49.40 | RavenClaw_78 | mib_gj3svv: the program i debug is a simple led off, led on loop, working well. so when the program sets the value nothing happens, the light stays on. you mean the write via openocd->jtag might trigger something...hmm I dint set anything up...maybe I should look at the bootstrap code? |
| 22:51.53 | mib_gj3svv | my standard suggestion is to try using a command window and the telnet interface, then set the momory location using mww (memory write word) command. This rules out strange Eclipse interactions, they are known to happen :( |
| 22:57.05 | mib_gj3svv | no I really mean that the write through openocd->jtag work, or you would se no short change, but then something changes it back |
| 22:58.26 | RavenClaw_78 | great ...that works ... |

| 22:59.30 | RavenClaw_78 | mib_gj3svv: thanx for the tip, never used the telnet interface before ... |
| 23:08.58 | mib_gj3svv | nice feature with cortex_m3 processors and openocd is you can write to memory and gpio registers while they are running |
| 23:09.38 | mib_gj3svv | of course then the code on the microprocessor can change it back at any moment. |
| 23:10.49 | RavenClaw_78 | very nice ...i currently write a peripheral register view for the cortex-m3 as part of my bachelor thesis, and modify is the last part missing ... |
| 23:11.11 | RavenClaw_78 | view for eclipse .. |
| 23:13.42 | mib_gj3svv | ... for me , I use openocd a lot but not eclipse, usually only telnet interface and sometimes raw gdb |
| 23:14.32 | mib_gj3svv | less strange uncontrollable things happen, and also less project management |
| 23:16.57 | mib_gj3svv | so if you want to create an eclipse view, telnet is great to test basic interaction and separate openocd problems from eclipse problems |
| 23:17.14 | RavenClaw_78 | thats right, maybe this view will be used in future university classe ...giving students a easyer first contact with microcontrollers ... |
| 23:17.55 | RavenClaw_78 | everything is working fine so far, just the writing part needs a little "kick" ...*G* |
| 23:18.16 | mib_gj3svv | nice to hear, good luck :) |
| 23:18.31 | RavenClaw_78 | thanx, and thanx for the talk :-) |
