| 00:35.41 | roxfan | well, my point is you're unlikely to find that info in armv7 doc |

| 16:36.44 | mlundin | Hi, is dirk around ? |
| 16:43.28 | dirk2 | mlundin: hi! |
| 16:43.35 | dirk2 | mlundin: Great work!! |
| 16:44.16 | mlundin | tested ? |
| 16:44.45 | dirk2 | the first part, stop and start the target |
| 16:45.03 | dirk2 | I did a md 0x80000000 0x4000 in U-Boot |
| 16:45.14 | dirk2 | then a lot of memory dump scrolls through |
| 16:45.28 | dirk2 | and you can see how the target stops and re-runs |
| 16:45.31 | mlundin | you asked for it :) |
| 16:45.49 | dirk2 | but you are right, doing this x times, it looks like the targets hangs then |
| 16:46.10 | dirk2 | mlundin: asked: Yes, many many thanks! |
| 16:46.42 | dirk2 | I'm currently writing a new summary with Strontiums scripts updated for the mailing list |
| 16:46.56 | mlundin | as I mentioned, there is alot to the proper procedure on how to cleanly stop and restarty, we dont do that |
| 16:47.00 | dirk2 | Then I will update the wiki, too, and test your commands step by step |
| 16:47.58 | dirk2 | mlundin: broken start/stop: No problem! I'm really happy that we are now near of 'doing real things' :) |
| 16:48.32 | dirk2 | and hopefully more people will step in when they see that we are near to do useful things |
| 16:48.34 | mlundin | You can also find the memory controller GPMC_BASE 0x6E000000 |
| 16:48.51 | dirk2 | that's why I try to keep the status up to date |
| 16:49.06 | mlundin | using , I think, dapsel 0 |
| 16:49.20 | dirk2 | mlundin: Great. Sounds like I will have something to play with at the weekend ;) |
| 16:49.49 | mlundin | This is in OMAP TRM 11.1.7.1 |
| 16:50.02 | dirk2 | ok |
| 16:50.12 | mlundin | We can see if we can match this to the memory config |
| 16:50.32 | mlundin | then we can try flash programming |
| 16:54.18 | dirk2 | mlundin: Enjoy the wine! |
| 17:06.32 | mlundin | :) |

| 17:09.50 | vkle | Hi! |
| 17:13.37 | mlundin | I am new to IRC so maybe I am shouting instead of directing conversations, is it nick: ? |
| 17:16.12 | vkle | I have some problems with openocd. Somebody have time to help me or give an advise? |
| 17:17.15 | mlundin | ask and answers might appear |
| 17:19.45 | vkle | Ok |
| 17:21.37 | vkle | I use an LPC2138 controller for automatic helicopter control... |
| 17:22.07 | vkle | I've installed new version of openOCD from yagarto toolkit... |
| 17:22.54 | vkle | I've rewrite old scripts with a new syntax... |
| 17:23.49 | pthomas__ | vkle, I'm new to openocd too, but maybe I can help. |
| 17:25.12 | mlundin | vkie: What does not work ? |
| 17:25.52 | vkle | wm |
| 17:26.40 | vkle | OpenOCD starts well. Info: JTAG Tap/device matched |
| 17:26.59 | vkle | LPC in reset state |
| 17:28.00 | vkle | When I'm trying to flash my LPC with command "monitor flash write_image erase main.elf elf" |
| 17:28.20 | vkle | OpenOCD says that everything OK. |
| 17:28.54 | vkle | But when I verify with command "monitor verify_image main.elf" |
| 17:29.22 | vkle | It sais that verification failed... |
| 17:30.20 | vkle | And I don't know how to fix this... |
| 17:33.55 | vkle | Anyone know? |
| 17:34.15 | pthomas__ | maybe the flash isn't set up correctly |
| 17:34.35 | mlundin | Possible cause, flash controller uses differnet memory address base from from the execution mapping |
| 17:34.46 | pthomas__ | you might use mdw and mww to test out the flash range |
| 17:35.06 | mlundin | Every supplier has different schemes, big confusion |
| 17:35.35 | mlundin | I mostly uses a .bin file |
| 17:35.57 | vkle | And how to use mdw and mww to test flash range? |
| 17:36.00 | mlundin | do manual erase flash erase_sector 0 0 nn |
| 17:36.36 | mlundin | flash write_bank 0 filename.bin 0 |
| 17:37.29 | mlundin | and verify_image filename.bin |
| 17:37.46 | vkle | Ok, wait a minute... |
| 17:37.50 | mlundin | Cannot use mww to flash |
| 17:38.06 | mlundin | Can try to use mdw |
| 17:38.16 | mlundin | But flash info 0 is best |
| 17:39.24 | vkle | flash info 0 says that banks 0-26 are protected |
| 17:40.08 | vkle | What does it mean "protected"? |
| 17:41.28 | vkle | When I use an ISP tool with NXP Flash Utility everithing is OK. |
| 17:41.49 | mlundin | usually no problem, the flash writer handles this for you |
| 17:43.54 | mlundin | just make sure the sectors receiving the image are erased, flash erase_check 0 |
| 17:45.47 | vkle | all sectors exept 0 are erased |
| 17:46.05 | vkle | flash erase 0 0 0 sais "invalid command name |
| 17:46.58 | mlundin | <PROTECTED> |
| 17:47.28 | mlundin | <PROTECTED> |
| 17:48.16 | vkle | done |
| 17:48.34 | vkle | but 0 sector not erased again... |
| 17:49.25 | mlundin | that is a report bug I think, try to falsh |
| 17:51.08 | mlundin | its on the list of strange output when openocd actually works :(, not yet investigated |
| 17:52.11 | vkle | flash write_image erase main.elf elf says "wrote 34728 bytes" |
| 17:52.29 | mlundin | now verify |
| 17:54.23 | vkle | done |
| 17:54.24 | vkle | checksum mismatch - attempting binary compare |
| 17:54.24 | vkle | Verify operation failed address 0x00000000. Was 0x34 instead of 0x18 |
| 17:54.24 | vkle | Runtime error, file "command.c", line 456: |
| 17:54.30 | mlundin | and reset run |
| 17:55.33 | vkle | reset run? and how about verification? |
| 17:55.54 | mlundin | try to write a bin file, not elf, my experience is much better with bin files |
| 17:56.05 | vkle | ok |
| 17:56.10 | vkle | wait a minute |
| 18:03.44 | vkle | the same result |
| 18:04.50 | vkle | but sectors [0-8] anre not erased |
| 18:08.00 | vkle | bad controller or openocd bug? |
| 18:15.42 | mlundin | dont mind the erase check messages they are weird, of the flash routine says "wrote 34728 bytes" that is what has happened. |
| 18:16.07 | mlundin | Ive done it lots of times on a LPC2124 |
| 18:16.38 | mlundin | What JTAG controller and jtag speed do you use ? |
| 18:17.22 | vkle | Olimex ARM-USB-OCD and jtag_speed 5 |
| 18:19.36 | mlundin | For an erased chip, and that is what you have by now, use something real slow, jtag_khz 30, and increas this when the program is up and running with clocks and pll configured |
| 18:20.40 | mlundin | jtag_speed 5 is like 1MHz an that is to much for an emty chip running off the reset clock |
| 18:22.34 | vkle | ok |
| 18:22.41 | vkle | trying... 30 kHz |
| 18:23.09 | mlundin | ok, got to go, hope this helps, good luck |
| 18:23.27 | vkle | Thanks! |
| 19:20.47 | vkle | 30 kHz don't work... the same error "checksum mismatch..." |
| 19:21.02 | vkle | and the same value 0x34 and 0x18 |
| 19:44.27 | vkle | It interesting 0x18 is the same that 0x34 but byte order is different... |
