| 01:05:51 | prpplague | Sammy: knee how |
| 01:07:16 | Sammy | prpplague : gau an :) |
| 01:08:02 | Sammy | maybe < jau anm > is better |
| 01:08:29 | Sammy | btw means mornong prpplague :) |
| 01:08:52 | prpplague | Sammy: well its night time here, i'm just heading home |
| 01:12:37 | prpplague | Sammy: how life in china these days? |
| 01:19:27 | Sammy | today in chinese Taipei : with sun and warm , no wind , and I like it almost spring |
| 01:20:04 | prpplague | Sammy: nice |
| 06:27:50 | Russ | why are so many people so incredibly clueless on arm-kernel? |
| 06:28:03 | Russ | don't mean to be mean or anything |
| 06:40:36 | Sammy | so poor ...... |
| 06:40:59 | Sammy | what you saw to made you say this ? |
| 07:13:25 | Sammy | any idea how to test ram ? |
| 07:15:00 | Sammy | here is the situation , I know the memconfig is currect copy into memsetup-sa1110 |
| 07:16:50 | Sammy | but still got led shine twice again and again after that ... so , any know's how to test memory is ok ? |
| 07:26:42 | Russ | your led flashes twice? |
| 07:27:41 | Russ | /* everything is said and done over here, call normal_boot in |
| 07:27:42 | Russ | * the generic startup code to continue the boot procedure */ |
| 07:27:42 | Russ | bl normal_boot |
| 07:27:42 | Russ | /* oops, normal_boot returns, something went wrong. signal an |
| 07:27:42 | Russ | * error to the user */ |
| 07:27:42 | Russ | mov r6, #2 |
| 07:27:44 | Russ | b endless_blink |
| 07:27:49 | Russ | you are returning from normal_boot |
| 07:28:13 | Russ | mem_test_loop: |
| 07:28:13 | Russ | mov r0, r5 |
| 07:28:13 | Russ | bl testram |
| 07:28:13 | Russ | teq r0, #1 |
| 07:28:13 | Russ | moveq pc, lr /* oops, something went wrong :( */ |
| 07:28:16 | Russ | could be returning here |
| 07:29:10 | Russ | whatever location you are specifying ram at ram isn't there, or, you have the registers setup wrong |
| 07:33:51 | Sammy | Russ : if that ram need to run more then 100Mhz and when I test , even change arch/<platform>.h file's memory setup .but still don't have any change ( I mean the Mhz still run 55Mhz) |
| 07:34:20 | Sammy | how can I test whic setup is wrong ? |
| 07:34:27 | Sammy | er which |
| 07:34:54 | Sammy | or the problem come from hw layout ? |
| 07:35:16 | Sammy | or maybe the chips is bed ....? how to know that ? |
| 07:36:37 | Russ | its a very simple memory test, not an intensive one |
| 07:36:44 | Russ | it just wants to make sure memory is there |
| 07:37:17 | Russ | verify that BLOB_ABS_BASE_ADDR is correct |
| 07:38:02 | Russ | as well as all of the memory defines |
| 07:38:17 | Russ | (ie, refresh, row/col, timings, etc) |
| 07:38:34 | Sammy | should I change memtest.S or memtest2.S 's code to make sure ? |
| 07:38:45 | Russ | no |
| 07:39:12 | Sammy | I think maybe is timing isn't currect , but I don't know how to make sure ? |
| 07:40:04 | Russ | start-sa1100.S calls testram in testram.S, which writes a few values and reads them back |
| 07:40:31 | Russ | read the sa1110 manual, and your SDRAM datasheets, also, check and see if there is any intermediate logic between the SDRAM and the sa1110 |
| 07:40:51 | Russ | for each register, determine from scratch what it should be |
| 07:41:23 | Russ | then, compare the values against what you are using now, and figure out why what you came up with is different, and which is correct |
| 07:44:21 | Russ | I gotta sleep though, good luck |
| 07:44:38 | Sammy | ok , I'll try thanx a lot :) |
| 07:45:03 | Sammy | have a good dream Russ :) |
