| 00:46.49 | EvilDevil | hi! can someone tell me the technical data of the diode (C54) on this board http://www.patrickschneider.info/100_1131.JPG ? or point me to some page where i can look it up myself? |
| 00:50.27 | joe_bleau | That's a tantalum capacitor, not a diode |
| 00:55.52 | fishhead | yeah I found that out now |
| 00:56.00 | fishhead | I knew it was either electro or tan |
| 00:56.04 | fishhead | cause they are the polarized ones |
| 00:56.23 | fishhead | I guess those 3 months at amptech paid off |
| 00:56.26 | fishhead | I just don't know the ratings etc |
| 00:57.07 | fishhead | that explains also why the +15v in instead of +5 in smoked it so easily |
| 00:57.11 | fishhead | tantalum are fragile |
| 00:59.04 | fishhead | joe you think it will run for a while without that cap |
| 00:59.10 | fishhead | I can't tell if it's inline etc |
| 01:00.22 | joe_bleau | Maybe. It's probably just a bypass cap. |
| 01:01.24 | EvilDevil | so, just unsolder it and put some lead there would bring this thing back? |
| 01:01.43 | fishhead | <fishhead> actually if you have real sharp clips you could just clip the leads to the cap |
| 01:01.43 | fishhead | <fishhead> without unsoldering |
| 01:01.43 | fishhead | <fishhead> don't damage the board though |
| 01:01.49 | fishhead | no leave nothing there for now |
| 01:01.56 | fishhead | see if the board will power up |
| 01:02.13 | fishhead | make sure nothing is left touching from the 2 ends of the cap |
| 01:02.27 | EvilDevil | i'll try this :) |
| 01:02.35 | fishhead | just unsolder it if you think you can't clip it without ripping up the board |
| 01:03.56 | fishhead | <fishhead> DUDE |
| 01:03.56 | fishhead | <fishhead> CLOTH LIKE THAT WILL STATIC SHOCK THE BOARD |

| 04:54.25 | fishhead | ppc board I don't need to know that much for a router setup |
| 04:57.51 | silverpower | Agreed. Most cars in my price range have non-functional or removed stereo hardware, so the sound chip needs to be good. |
| 04:58.34 | silverpower | But if you need to use an FM transmitter, sound quality is a moot point. 80db S/N under ideal conditions. |

| 06:57.14 | fishhead | hahaha |
| 06:57.20 | silverpower | For that matter, aptitude isn't much better. |
| 06:57.22 | fishhead | rpm baby |
| 06:57.26 | fishhead | that was what I used for yrs |
| 06:57.28 | fishhead | before I burned out |
| 06:57.48 | silverpower | I don't care for RPM either. |
| 06:58.52 | silverpower | Give me Slackware-style TGZ, Arch's pacman (never tried it, but I like it already), and Gentoo's Portage, as well as the BSD-style Ports/pkgsrc system. |
| 06:59.30 | silverpower | Those have clear advantages over .deb and .rpm. |
| 06:59.46 | silverpower | apt-get is a good model, but it's just that - a model. |
| 07:00.47 | fishhead | I like gentoo package system too |
| 07:01.49 | silverpower | I liked slapt-get when I used it. |
| 07:01.55 | fishhead | I hate slack |
| 07:01.57 | fishhead | sorry :P |
| 07:02.20 | silverpower | I like it, but it's clearly not for everyone. |
| 07:02.50 | fishhead | I used to like text mode irc |
| 07:02.54 | fishhead | now I can't deal with it |
| 07:03.16 | silverpower | What's wrong with irssi? |
| 07:03.55 | silverpower | I tried xchat, it was all right, but I prefer irssi. Makes more sense, IMO. |
| 07:04.06 | fishhead | actually irssi looks good |
| 07:04.10 | fishhead | if you can seperate windows and stuff |
| 07:04.17 | fishhead | I just can't do the all in one screen thing anymore |
| 07:04.29 | fishhead | something burned in my brain all those yrs of different meds |
| 07:04.41 | silverpower | Ah. That's my favorite feature, actually. |
| 07:04.54 | fishhead | all in one ? |
| 07:05.00 | silverpower | Yes. |
| 07:05.04 | fishhead | ugh |
| 07:05.21 | silverpower | Except that I have to have one instance per server, which is annoying. |
| 07:06.21 | silverpower | Do you mean having no ability to switch between different 'tabs'? |
| 07:06.52 | silverpower | Or do you simply prefer that your WM do all the switching tasks? |
| 07:07.47 | silverpower | I like the irssi method, because if there's something to pay attention to, I can simply hit alt-<number>. It works for me. |
| 07:09.23 | silverpower | I can't stand emacs now (fsf or xemacs). Part of it I like, but the way it handles buffers doesn't make any sense to me. I prefer seperate tabs. xemacs fixes this behavior partially, but it's still annoying. |

| 16:56.19 | joe_bleau | This is to allow running from ram without relying on any existing flash code to configure the system |
| 16:56.39 | joe_bleau | If it works, it means that a ram resident ppcboot could be installed and ran on a 'bricked' board |

| 17:28.22 | GPSFan | joe_bleau: finally fot 1.16 working out of flash, I bricked my board last night by writing a faulty image at fff80000, just got recovered and fixed the problem. |
| 17:30.03 | GPSFan | the normal has to cycle the memory controller off then on again to get the values to "stick" if that happens while running from ram, crash!! |
| 17:32.52 | GPSFan | s/normal/sdram config code |
| 17:32.55 | joe_bleau | SDRAM config off, config timing, etc., then SDRAM controller back enabled? |
| 17:33.30 | GPSFan | yep, that screwed me up 'cause I had it turned off for the ram based version. |
| 17:33.49 | joe_bleau | Well, I'm uploading the recovery macro stuff now. |
| 17:34.30 | GPSFan | I built a couple of useful ones too. btw your hh program was very usseful in recovering. |
| 17:35.09 | joe_bleau | Glad it helped. Data breakpoints looked to be too complicated to parse the command line, so I punted. |
| 17:35.10 | GPSFan | I'll gen up a 1.1.6 ram based version to go with it. |
| 17:35.29 | joe_bleau | I *really* wanted to have a procedure for brick recovery before I test your flash version |
| 17:35.45 | joe_bleau | Not that I don't trust you, rather that I don't trust my typing |
| 17:36.21 | joe_bleau | I hate wiki |
| 17:36.32 | GPSFan | sometimes I don't trust myself or typing either, earlier I flshed ppcboot.jpg to fff80000, wierd results on reset !!! |
| 17:39.20 | joe_bleau | OK, the macro and the logs to prove it works are up. |
| 17:39.56 | GPSFan | I can send you the ppcboot 1.1.6 set up for ram to try. |
| 17:40.43 | joe_bleau | As I understand it, we need a version to run from flash (production) and one to run from ram (recovery), correct? |
| 17:40.57 | GPSFan | yes. |
| 17:41.11 | joe_bleau | ram resident version should be an s-record file, as it'll only be loaded from ocd commander |
| 17:41.30 | GPSFan | that's what I'm sending you. |
| 17:41.45 | joe_bleau | Receiving now |
| 17:42.07 | GPSFan | try loading that from ocd and see if it's ok. |
| 17:42.32 | joe_bleau | I'll also need a flash resident version. It should be a binary file, to load using loadb from inside the existing ppcboot v1.1.2? |
| 17:42.38 | joe_bleau | Sure, standby |
| 17:43.11 | joe_bleau | Should I allow the 1.1.2 flash to config the system, or use the macro right out of reset? |
| 17:43.38 | GPSFan | either 1.1.2 or your .mac needs to set up the sdram controller |
| 17:44.52 | joe_bleau | macro ran, downloading now |
| 17:44.58 | GPSFan | in a bricked board you won't know if the sdram controller has been set up or not, so your .mac is critical to recovery. |

| 18:12.54 | joe_bleau | Max Klein is the guy (post-doc, prof?) at Stanford that put out the .pdf on how to boot linux on the board |
| 18:13.11 | GPSFan | ah, gotit.. |

| 18:14.31 | joe_bleau | lemme see |
| 18:15.40 | joe_bleau | Nope, it went ahead and re-ran the kernel from last time instead of setting the env var |

| 18:18.45 | GPSFan | do you think the recovery procedure/tools/ppcboot.srec is good enough? |
| 18:18.50 | joe_bleau | Hey, I've got to run around in a bit |
| 18:18.53 | joe_bleau | I want to test that. |
| 18:19.00 | joe_bleau | How many sectors does the new bootloader take? |
| 18:19.13 | GPSFan | I'll dcc you the bin for fff80000 |
| 18:19.21 | joe_bleau | I'm gonna back up my current one, and yes, I want yours |
| 18:19.30 | joe_bleau | I'm fairly confident I can recover if needed |
| 18:20.19 | joe_bleau | using 0xfffb for env, leaves three sectors free, right? |
| 18:20.35 | GPSFan | when you flash it verify it copied properly before reseting. |
| 18:20.48 | joe_bleau | I always do. |
| 18:20.52 | GPSFan | and re-protect the flash to. |
| 18:21.06 | GPSFan | too even |
| 18:21.10 | joe_bleau | Does it matter? I've always seen it ignore any additional protect I put on |
| 18:21.24 | joe_bleau | So, let's see. |
| 18:21.30 | GPSFan | don't know for sure. |
| 18:21.34 | joe_bleau | First, unprotect 0xffc through 0xfffe |
| 18:21.39 | joe_bleau | erase those three sectors |
| 18:21.46 | GPSFan | no fff80000 fffaffff |
| 18:22.05 | joe_bleau | copy from 0xfff8 to 0xfffc, three sectors (backup 1.1.2) |
| 18:22.09 | joe_bleau | stay with me here... |
| 18:22.26 | joe_bleau | protect 0xfffc to 0xffff |
| 18:22.36 | GPSFan | this is what I do. |
| 18:22.38 | joe_bleau | load new image to ram |
| 18:22.48 | GPSFan | loadb 400000 115200 |
| 18:22.51 | joe_bleau | erase sectors 0xfff8 to fffa |
| 18:23.00 | GPSFan | erase fff80000 fffaffff |
| 18:23.03 | joe_bleau | copy from ram to first three sectors |
| 18:23.14 | joe_bleau | protect on those three |
| 18:23.19 | joe_bleau | and I should be golden? |
| 18:23.20 | GPSFan | cp.b 400000 fff80000 30000 |
| 18:23.30 | joe_bleau | Yeah, I've done this before. |
| 18:23.40 | joe_bleau | Remember, I tried to put 1.1.2 at 0xfffc for fun. |
| 18:23.52 | joe_bleau | and I used cmp.w along the way, too |
| 18:23.55 | GPSFan | ah. |
| 18:24.15 | GPSFan | use cp.b since you are flashing 8 bit flsh. |
| 18:24.29 | joe_bleau | basic idea sound? Backup 1.1.2 to unused sectors, load new 1.1.6, unprotect, erase, copy, compare, protect, reboot? |
| 18:24.46 | joe_bleau | cp.b vs. cmp.w... |
| 18:25.00 | GPSFan | give it a try, ;>) |
| 18:25.16 | joe_bleau | ok, maybe be a bit, so don't hold your breath. Got something to do first. |
| 18:25.24 | GPSFan | cul.. |
| 18:25.29 | joe_bleau | BTW, enjoy the recovery macros. Hope you don't need 'em... |
| 18:25.44 | joe_bleau | I'll say logged in to monitor progress. |
| 18:26.00 | joe_bleau | And once again, thanks for all the work. I know it hasn't been easy. |
| 18:28.22 | GPSFan | I think 1.1.6 is pretty close to done, thanks for the support!! |
| 18:41.19 | joe_bleau | Seriously, if there's something missing, make me a todo list |
| 18:52.24 | GPSFan | ok, look through the cmd_nvedit.c and see if you can figure out why it doesn't like the 2 command bootcmd. |
