| 02:13:19 | BZFlag | ibot: seen Russ|werk |
| 05:42:46 | Russ | I'm here |
| 17:08:34 | rmk | whee, jread works ;) |
| 19:42:32 | Russ | rmk: jflash cleaning up nice? |
| 19:43:34 | Russ | serenade what? |
| 19:43:37 | rmk | well, not jflash, but jread |
| 19:46:28 | Russ | once you get all the cell stuff done, will jflash be sa1100/sa1110 independant? |
| 19:46:49 | rmk | should be. |
| 19:47:08 | Russ | (besides different flash and plaiting) |
| 19:47:26 | rmk | I do need someway of describing various setup things first tho. |
| 19:48:07 | rmk | (at the moment, quite a bit is done by hard-coded lookups for things like "A26..A0" and "D31..D0", "nOE" etc |
| 19:50:33 | Russ | I think something that would set the proper chip selects, data direction, and address lines for a paticular 32 bit address read/write |
| 19:50:48 | Russ | maybe thats too high level |
| 19:52:33 | Russ | was there any serial console sysrq problem in 2.4.6-rmk2 or 2.4.6-rmk2-np1? |
| 19:52:55 | rmk | don't remember any |
| 19:53:14 | Russ | never worked on the tuxscreen for me |
| 19:55:31 | rmk | 512KB read using a slow machine: real 2m23.092s |
| 19:55:50 | Russ | sounds about righ |
| 19:55:51 | Russ | t |
| 19:56:05 | Russ | but again, I think your limitation is the parallel port |
| 19:56:15 | rmk | probably. |
| 19:57:09 | rmk | hmm, the possibilities are endless... could implement a gdb debugger stub on top of this... |
| 19:57:16 | Russ | what you really need is to attach 4 gpio's to the jtag lines, and pet send schedule timeout's in the driver to keep it at 20MHz |
| 19:57:31 | Russ | rmk: you'd need something other than a SA11x0 |
| 19:57:45 | Russ | but I imagine you do |
| 19:59:17 | rmk | thinks implementing a SDRAM driver via jtag will be _really_, probably too slow |
| 20:00:16 | Russ | it would be impossible |
| 20:00:26 | Russ | there would be no way to catch the refreshes |
| 20:00:59 | Russ | much less match the read/write timings |
| 20:03:31 | rmk | I'm going to have to do a massive cleanup on the jread code - most of the stuff I bunged into there should be in a library. |
| 20:06:26 | Russ | maybe a flash memory library can go along with it |
| 20:07:01 | rmk | could do - you feed it the device, and the offsets in the boundary chain to wiggle for various things, and it does the rest. |
| 20:07:36 | Russ | I mean for something like jflash to communicate with the flash memory attatched to the CPU |
| 20:36:24 | rmk | looks at erikm |
| 20:37:09 | erikm | hi rmk |
| 20:37:25 | Russ | morning erikm |
| 20:37:37 | erikm | nah, evening |
| 20:37:55 | rmk | very late evening to you too |
| 20:37:57 | erikm | computer maintenance at parents place |
| 20:38:00 | Russ | yah, so, its 2:30 here and I woke up less than an hour ago |
| 20:40:50 | erikm | I've been thinking a bit about blob (wow, what a surprise! :), and I don't think we should put the parameter block stuff in right now |
| 20:41:09 | Russ | what else is there to fix first |
| 20:41:35 | erikm | nothing, I just get the feeling that it will take quite some time to get it right |
| 20:41:42 | Russ | before cramfs/jffs2/tftp stuff goes in, I would think it would need a paramater blocks |
| 20:42:13 | Russ | make a head tag, tail tag, and a tag y/n load ramdisk tag |
| 20:42:14 | erikm | *nod* |
| 20:42:43 | Russ | then add a autoboot timeout tag |
| 20:42:50 | erikm | yes, I know, I know. but I think we'd better declare what we now have "stable" |
| 20:42:57 | Russ | just some stuff to get the ball rolling |
| 20:42:59 | Russ | oh, that |
| 20:43:03 | erikm | exactly |
| 20:43:05 | Russ | I suppose thats important |
| 20:43:23 | erikm | because the other stuff will take at least a month to stabalise |
| 20:44:18 | rmk | wonders if the command line processor will accept ^u as well as ^h/del |
| 20:44:21 | Russ | add flash timings maybe? |
| 20:45:04 | erikm | rmk: not yet |
| 20:45:19 | rmk | takes that to mean "in time, yes" |
| 20:45:23 | rmk | grins |
| 20:45:59 | erikm | rmk: yes :) |
| 20:46:11 | erikm | Russ: you mean flash memory setup? |
| 20:46:42 | Russ | yes |
| 20:47:13 | erikm | Russ: that would be OK, not really intrusive |
| 20:51:50 | erikm | goes zzz |
| 21:02:03 | Russ | hey BZFlag |
| 21:09:40 | BZFlag | hey. recovered yet from lack of sleep? ;-) |
| 21:10:19 | Russ | slept 14 hours |
| 21:11:45 | Russ | hey, its a little past 3 |
| 21:11:56 | Russ | (24hr disconnect at work) |
| 21:12:47 | BZFlag | 3pm, yes? I'm in UT, 4pm here. |
| 21:22:57 | Russ | flash timings for shannon committed to blob |
| 21:27:13 | Russ | hrmm...maybe I did something wrong...erasing sectors seems like it might be taking longer... |
| 21:29:16 | Russ | on www.tuxscreen.net, why does it say "Lucent DSP") |
| 21:47:01 | Russ | you there? |
| 21:47:42 | rmk | who, here? ;) |
| 21:48:50 | Russ | BZFlag: |
| 21:50:28 | BZFlag | from time to time. |
| 21:50:44 | Russ | why does it refer to a "Lucent DSP" on the tuxscreen pages? |
| 21:51:01 | BZFlag | Russ: that should be where the docs on the DSP go. if and when we get some. |
| 21:51:17 | Russ | where did you find out its a lucent DSP |
| 21:51:49 | BZFlag | that's just a rumor. the link has been there all along. I just reformatted the page to remove the frames, and left that one there. |
| 21:52:02 | Russ | where did the rumor start |
| 21:52:12 | Russ | this would be the hidden chip |
| 21:54:45 | rmk | spots a jtag connection point ;) |
| 21:54:55 | Russ | yah, I was thinking about that |
| 21:55:11 | Russ | but I once I read the ID code, where do I look it up? |
| 21:56:23 | rmk | BZ: do these come with 230V power supplies as well as 110V ? |
| 22:24:32 | rmk | BZ: please mail me the answer ;) |
