| 02:15:49 | Sammy | hello prpplague :) |
| 02:17:07 | prpplague | hello |
| 02:17:11 | prpplague | how are you today? |
| 02:18:23 | Sammy | feel good , raining outside and feel not so hot .. |
| 02:18:51 | prpplague | good |
| 16:06:23 | Fare | hum |
| 19:33:54 | seletz_ | hoi |
| 19:34:24 | seletz_ | prpplague: still workin? |
| 19:36:34 | prpplague | seletz_: yep |
| 19:37:00 | prpplague | still got 5 more hours to go |
| 19:37:05 | Fare | gakuk! |
| 19:37:17 | Fare | btw, can you suggest how I can debug linux? |
| 19:37:29 | Fare | it dies when trying to enable the MMU |
| 19:37:52 | Fare | are you subscribed to linux-arm-kernel? |
| 19:38:18 | seletz_ | yup |
| 19:38:46 | seletz_ | use printk() is the only advice i can give. But rmk is working on your problem, isnt he? |
| 19:39:23 | Fare | hum, I don't think he is |
| 19:39:33 | Fare | I don't think he has enough information to |
| 19:39:34 | seletz_ | the mmu problem? |
| 19:39:39 | Fare | and since he didn't ask for more... |
| 19:39:49 | seletz_ | hrm |
| 19:40:44 | prpplague | Fare: http://www.abcsinc.com/small-linux/printascii.txt |
| 19:41:06 | seletz_ | i think this one he's already got |
| 19:42:03 | Fare | prpplague: yes, I'm using it |
| 19:42:11 | Fare | thanks to you -- it's been very useful |
| 19:42:43 | Fare | but somehow, linux dies while mapping memory and/or never recovers the ability to printk on serial |
| 19:43:02 | Fare | maybe trying to access serial even accelerates the crash as linux accesses unmapped pages |
| 19:43:16 | seletz_ | fare, maybe we could simulate your situation on my board. |
| 19:43:34 | seletz_ | then we could verify whether or not its a kernel problem. |
| 19:43:49 | seletz_ | what do you think? |
| 19:44:09 | seletz_ | or have you a assabet or similar around? |
| 19:45:22 | Fare | I only have my jornada820 |
| 19:45:44 | Fare | and I have no clue what kind of simulation that would be. |
| 19:45:50 | seletz_ | what did you already change (kernel...) |
| 19:46:04 | Fare | a few changes to the kernel in the attempt to port it |
| 19:46:15 | seletz_ | fare, well, moving thze kernel up in memory. |
| 19:46:19 | Fare | and to blob in the attempt to port it, too |
| 19:46:30 | Fare | I also moved the kernel up in memory, indeed |
| 19:46:36 | prpplague | Fare: ohh ok |
| 19:46:43 | Fare | maybe I should tell it not to use lower memory at all |
| 19:47:03 | seletz_ | dont you do that?? |
| 19:47:04 | Fare | (Currently, I just tell blob to tell the kernel not to map the page around 0xc005c080) |
| 19:47:22 | seletz_ | ah, i remember |
| 19:47:29 | Fare | (and load the kernel itself at 0xc0068000) |
| 19:47:30 | Fare | 68000 ! |
| 19:47:40 | Fare | nobody expects the 68000 ! |
| 19:48:23 | seletz_ | 64MB total on the jornada? |
| 19:49:37 | Fare | no, only 16MB |
| 19:49:46 | seletz_ | hmm |
| 19:49:53 | Fare | (though there exists a rare 16MB expansion kit) |
| 19:50:03 | Fare | WinCE is in ROM, not flash |
| 19:50:08 | seletz_ | maybe you want to try again w/o a hole in the map, i.e use only 8 mb |
| 19:50:31 | Fare | yes, I intend to try that |
| 19:50:56 | Fare | but I suppose I still need the page memory at 0xc0000000 for the vectors, don't I? |
| 19:51:13 | Fare | Or maybe the MMU makes it irrelevant? |
| 19:51:19 | seletz_ | i dont know really. |
| 19:51:27 | seletz_ | i think its MMUd |
| 19:51:32 | Fare | ok |
| 19:51:38 | Fare | makes sense, actually |
| 20:27:21 | seletz_ | BZFlag: hi |
| 20:28:17 | prpplague | BZFlag: howdy |
| 20:28:29 | prpplague | BZFlag: hows life mr.cto |
| 20:29:45 | BZFlag | busy busy |
