| 05:36.25 | enlight22 | sjhill: good and bad |
| 05:36.47 | sjhill | okay |
| 05:36.47 | enlight22 | i thought i bricked it once, mounted the disc on chip using a script i found |
| 05:37.03 | enlight22 | and the watchdog restarted it and it went into a boot loop |
| 05:37.13 | enlight22 | switching off didnt fix it |
| 05:37.16 | enlight22 | but unplugging it did |
| 05:37.17 | enlight22 | lol |
| 05:37.51 | enlight22 | but i didn figure out how to really enable the watchdog process |
| 05:37.54 | enlight22 | got it not rebooting now |
| 05:38.07 | enlight22 | and i got the real passwd and shadow file, was on the disc on chip |
| 05:38.27 | enlight22 | im trying desperately to get the network support up, so i can dump a complete image |
| 05:38.38 | enlight22 | since i cant figure out a good way to do it over the serial connection |
| 05:38.47 | enlight22 | but im having a weird weird problem |
| 05:40.07 | enlight22 | did figure out, have to load a wdt module, then start something |
| 05:41.45 | enlight22 | feel like helping me with this network issue, i think i sort ofknow what is teh problem, but i dont know where to begin to fix it, lol |
| 05:44.58 | a7r | enlight22: hmm.. what's the network issue? |
| 05:46.24 | enlight22 | something weird is going on, when it boots, the boot process shows the ethernet, and says no phy detected, and a mac adress that isnt the one printed on the device, |
| 05:46.46 | enlight22 | then, if i allow the device to continue booting normially, whithout doing init in the boot args to get to a shell |
| 05:46.59 | enlight22 | later in the process it loads the actually femtocel ubicell program |
| 05:47.08 | a7r | is this an smsc chip? |
| 05:47.17 | enlight22 | and that program somehow makes the ethernet work, with the mac address that actualy is printed on the device |
| 05:47.56 | enlight22 | i tried running that program from the shell, after analyzing the init scripts to see what is going on, and when you run it, it brings up the ubicell program, gets a dhcp lease correctly, but then reboots because it somehow knows it didnt start normally |
| 05:48.28 | enlight22 | its a cortina wjlxt972c |
| 05:50.15 | a7r | that's the phy though, right? |
| 05:50.24 | enlight22 | i believe so, yes |
| 05:50.33 | a7r | what's the MAC |
| 05:51.06 | a7r | like, what's the actual ethernet controller? |
| 05:51.46 | enlight22 | durring initial boot, (if i use boot args to get shell and even on a normal boot, it says smc91x.c: v1.1, sep 22 2004 by Nicolas Pitre <nico@cam.org> |
| 05:51.49 | enlight22 | eth0: at 0xc488a300 IRQ 11 [nowait] |
| 05:51.52 | enlight22 | eth0: Ethernet addr: 00:a0:1e:a8:7b:cb |
| 05:52.08 | a7r | right,... it's autogenerating that MAC. |
| 05:52.12 | enlight22 | but that hardware address isnt the one that is printed on the case, and also isnt the one it uses if i allow it to boot normally and it starts working |
| 05:52.17 | a7r | er the wrong MAC address |
| 05:52.20 | enlight22 | well that mac is the same every boot |
| 05:52.45 | enlight22 | there are no SMC chips on this board anywere, as well |
| 05:53.06 | a7r | I'm working on a board that does something similar.. it's passed to the driver after boot, before it's brought up. |
| 05:53.12 | a7r | and if you don't bring it up, well.. you get the generated MAC. |
| 05:53.15 | a7r | address |
| 05:53.20 | enlight22 | so i tried doing ifconfig eth0 hw ether (adress)_ and then starting dhcpcd |
| 05:53.23 | enlight22 | but that doesnt work |
| 05:53.50 | enlight22 | to change it to the correct hardware address |
| 05:54.41 | enlight22 | but it does work if the propriatary ubicell program runs (which isnt a script but a binary that calls dhcpcd after doing some other magic that makes the ethernet work) |
| 05:56.23 | a7r | can you get ubicell on a different machine, and pull it apart? |
| 05:56.34 | enlight22 | if i do let it boot totally on its own, this is what happens durring the last steps that make ethernet work |
| 05:56.56 | enlight22 | a7r: the binary? i only have a serial connection to the device, and i cant figure out any way to transfer files over it, i wanted to do that |
| 05:57.11 | enlight22 | UbiCell loader is starting. |
| 05:57.40 | a7r | enlight22: you can't run stty on serial console, make it raw, and then push it out that way? |
| 05:58.08 | enlight22 | maby i can, but i only started using linux on my desktop 1.5 years ago, and ive never had to do anything like that |
| 05:58.17 | enlight22 | someone suggested taring it and piping that to the console |
| 05:58.28 | enlight22 | i tried that and it came through, and i captured it on the pc end with cat |
| 05:58.35 | enlight22 | but the resultaly file was not readable |
| 05:58.48 | enlight22 | so basically i dont know what im doing |
| 05:59.12 | enlight22 | UbiCell loader is starting. |

| 06:00.51 | enlight22 | and its taking john forever to crack the shadow file |
| 06:00.53 | enlight22 | lol |
| 06:12.05 | enlight22 | can u give me any hint about how to transfer this file over the serial connection? |
| 06:17.26 | a7r | enlight22: stty raw is a start. did you do that before you tried pushing your data? |
| 06:20.39 | enlight22 | no |
| 06:20.55 | enlight22 | if i set it raw, how will i issue commands to start it, wont the commands be in ascii |
| 06:21.14 | a7r | write a script that sets it, pushes the data, and then sets it back. |
| 06:21.19 | enlight22 | im sure the reason the resuting file was unreadable was because it was in ascii mode, or not a binary mode transfer |
| 06:21.42 | enlight22 | ive looked all over google, i cant believe there isnt a script that already does this, lol |
| 06:21.43 | a7r | there's no ascii or binary mode.. there's processed terminal with the right baudrate, and unprocessed with the right baudrate. |
| 06:21.58 | a7r | so use stty to configure things correctly, and you should be able to read from it. |
| 06:22.02 | enlight22 | and i would have to echo the script to the remote board i guess, into a file |
| 06:22.11 | a7r | sure. |
| 06:22.53 | enlight22 | ugh, time to learn shell scripting i guess, why hasnt someone done this before and just conveniently put it on the internet under the title how to trasfer files over serial console |
| 06:23.51 | a7r | you get to file this experience under "foundation learning". ;) |
| 06:24.32 | enlight22 | hehe, i want this learning, but i want this ethernet interface up now, im sick of this serial console, the thing has sshd on it, and scp, an it would be a trivial matter to dump the entire thing with that |
| 06:26.46 | a7r | tell me about it.. I just got my kernel booting on this board, but I have to use USB mass storage. |
| 06:27.01 | a7r | so it's sneaker net back and forth. |
| 06:27.13 | enlight22 | ugg |
| 06:27.29 | enlight22 | even USB would be preferable, i just want to dump every file on this board to my pc for review |
| 06:27.41 | a7r | everything is stored on flash? |
| 06:27.44 | enlight22 | and i know this OMAP 1710 has usb host and device mode |
| 06:27.56 | enlight22 | yes, its stored on a sanddisk MDOC |
| 06:29.24 | enlight22 | there is like zero info on this proc, so i cant dump it over jtag, they didnt bring the usb out anywhere that i can tell, i gotta get ehternet up and running :( |
| 06:29.39 | enlight22 | they didnt even bring the console out, i found it with a scope and bus pirate |
| 06:30.13 | a7r | werd. |
| 06:30.28 | a7r | well now you have a shell and root, you can pretty much do anything. |
| 06:30.55 | enlight22 | haha, only i cant unless i can get the network up, or figure out how to transfer files over this horrid serial crap |
| 06:32.03 | enlight22 | im more of a hardware guy, it would be simpler for me to unsolder this BGA disc on chip and hook it up to my pc i think, but i dont wanna wreck this thing, its the only one ive got |
| 06:32.30 | a7r | ah |
| 06:32.52 | a7r | well like I said, you can do anything you want.. you just have to get creative with how the data is getting on and off the device. |
| 06:33.58 | enlight22 | hmmm |

| 16:02.44 | enlight22 | sz |
| 16:02.58 | enlight22 | idk, this thing is giving me no end of grief |
| 16:06.48 | wmat | is building whatever you need statically yourself not an option? |
| 16:10.24 | enlight22 | i could build it, but what a pain |
| 16:10.32 | enlight22 | and its for this omap 1710 that there is no documentation for |
| 16:10.54 | enlight22 | i just need either someone who really knows their stuff to help me get the ethernet interface working |
| 16:11.18 | enlight22 | or i need to copy this binary over the serial console connection, and see how it does it, |
| 16:11.28 | enlight22 | its the binary for the main femtocell process |
| 16:11.58 | enlight22 | the problem is it knows if its started through any means other than the normal boot process and some annoying ting called mortem restarts the system |
| 16:12.17 | enlight22 | if you modify the file system it also knows and restarts it and a fresh filesystem is loaded from a tgz |
| 16:12.21 | enlight22 | its driving me nuts |
| 16:12.37 | enlight22 | it has ssh and scp on it and if i could get the ethernet interface working id be fine |
| 16:13.05 | enlight22 | ppl keep telling me to pipe it in raw mode though the serial port but im at a loss as to how that is done |
