1	Linux Stuff / Kernel / Re: Boot no more	on: October 14, 2009, 04:02:05 PM
Even though I did not really get to install the Kernel to my other Plug, I did find that login into the bogus Plug always stalls at the same point. Using debug-output I discovered that the Login itself works quite well (even though horribly slow). The process seems to hang when sh is about to be invoked: Code: debug2: we sent a password packet, wait for reply debug1: Authentication succeeded (password). debug1: channel 0: new [client-session] debug2: channel 0: send open debug1: Requesting no-more-sessions@openssh.com debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug2: channel 0: request pty-req confirm 1 debug1: Sending environment. debug1: Sending env LANG = en_US.UTF-8 debug2: channel 0: request env confirm 0 debug2: channel 0: request shell confirm 1 debug2: fd 3 setting TCP_NODELAY debug2: callback done debug2: channel 0: open confirm rwindow 0 rmax 32768 Now, I am not an SSH-Expert. But from what I have found on the Web this seems to be related to a read-command for the filesystem (invocation of sh as mentioned above would be my guess). I am beginning to think that the SD card itself might be broken. Any clues from the experts on this?

2	Linux Stuff / Kernel / Re: Boot no more	on: October 14, 2009, 11:01:04 AM
Kind of wondering why I did not find that when consulting the Forums Search-function. Anyway... Thanks for pointing that out. As I did not upgrade my GIT-Sources in between my Kernel Builds (and the system was running stable before), this would be related to the most recent changes in my Kernel. I guess... However, that does not seem to fit: Code: /mnt# diff usr/src/linux/.config usr/src/linux/.config.old 4c4 < # Tue Sep 29 15:25:03 2009 --- > # Tue Sep 29 15:09:54 2009 1039c1039 < CONFIG_MEDIA_TUNER_XC5000=y --- > CONFIG_MEDIA_TUNER_XC5000=m 1096c1096 < CONFIG_VIDEO_CX231XX_DVB=y --- > # CONFIG_VIDEO_CX231XX_DVB is not set However, my symptoms to not fit anymore anyway. I had an fsck done to the SD-Card which holds my OS and after fixing several issues it now boots again. Now I am stuck during login as it just "hangs" after entering my password. At this point I am really curious about what is going on there. My next step will be to install the Kernel from the bogus Plug on the Plug I have here. Maybe I can recreate the problem and figure out a solution (f.ex. see if that Kernel-Patch might help).

3	Linux Stuff / Kernel / Boot no more	on: October 14, 2009, 08:33:53 AM
Some Plug of mine seems to have said goodbye for now. To make things worse it is in overseas, so I can hardly take a look at it. However, I managed to get an Image from the Plugs SD-Card, so I have Log-Files at hand. First, the symptoms. I was building Kernels to get some PVR-Stuff up and running on the Plug. Everything went fine - and I only touched V4L-related things. However, a couple days later I could not log into the Plug anymore. Turned out that it was not available from its local net either. A reset did not help either. So, what does the log say about this?

It is always the exact same message that is being dumped. And from what I can see there is no other activity on the System (say: booting up into a defined state). Of course, services like SSHd are not available. Anybody seen something like that? I am afraid that the Kernel-Portion of the Plug got hit by a bad-block (which means I would have to have the Plug shipped over to the US to take care of that).

I for myself find openplug.org far more fancy than plugcomputer.org.

5	General Category / General Discussion / Re: Long pause to mount root during boot	on: May 17, 2009, 05:06:24 PM
iirc this was related to an error-check of your nand-partition due to an unclean shutdown.

Do you guys have loaded/compiled the SDHCI-Module?

7	General Category / Success stories / Re: USB Webcam as a surveillance camera	on: May 14, 2009, 08:30:02 AM
I did the same - but using VLC as a Streaming-Server instead of webcam-server. CPU-Load is roughly at 3% as I am just forwarding the MJPEG-Stream of my webcam.

8	Linux Stuff / General Linux questions / tar-Question	on: May 13, 2009, 08:35:03 AM
I have this script that is supposed to pack all my stuff into a single tarball once a week. It seems to work pretty good and get the job done. At least that was what I thought when I set it up. Quote tar cvpzf $HOST_DIR/backup.tar.gz / --exclude="/sys/" --exclude="/mnt/" --exclude="/proc/" --exclude="/lost+found" --exclude="/media/" --exclude="/root/toril/*" --exclude-caches Now I noticed that according to the tarballs size it cannot be my whole file system anymore. Rather a delta to the last compression. And indeed, when I take a look inside them they do not contain the complete file system anymore. Quote -rw------- 1 root root 1962344 May 10 05:09 backup.tar.gz -rw------- 1 root root 493408458 May 7 11:49 backup_old.tar.gz However, I could not find a switch deactivating this kind of behavior. Can anyone tell me what I might be missing?

9	Linux Stuff / Linux distributions / Re: Debian running on the plug	on: May 01, 2009, 07:06:35 PM
Yeah, that's what I did again. Just wondered if there might be a nicer solution to this. The Kernel needs to come from the orion-repositories, sure thing - and no biggie to me. I need to make my own uImage anyways so it doesn't really affect me.

10	Linux Stuff / Linux distributions / Re: Clock working?	on: April 30, 2009, 10:34:14 AM
My clock seems to work ever since. However, during boot-time I still get an error: Code: Setting the system clock. Cannot access the Hardware Clock via any known method. Use the --debug option to see the details of our search for an access method. Unable to set System Clock to: Thu Apr 30 17:30:52 UTC 2009 (warning). Thanks nevertheless!

11	Linux Stuff / Linux distributions / Re: Debian running on the plug	on: April 30, 2009, 10:29:50 AM
As I messed up my almost final Debian-Installation today (cry) I was wondering if one could easily boot into one of the official Installation-CDs by just copying them to an USB-Stick and passing an appropriate boot-string via U-Boot. However, I could not find a RAM-Disk image in either of those images. Anyone tried something like that yet?

12	Linux Stuff / General Linux questions / Re: Trouble following "Boot USB" wiki	on: April 30, 2009, 05:16:56 AM
Are you sure you want to use mkfs.vfat? If you do so, you obvioulsy need to have a VFAT-Module for your Kernel. I used mkfs.msdos and did not have any problems at all.

If you wants source files then let me know your e-mail, then I'll send it via e-mail. Nope, that did not work for me either. But you can upload it on RapidShare or something like that.

This should do the trick: Code: apt-get install usbutils locate

15	Linux Stuff / Linux distributions / Re: Clock working?	on: April 26, 2009, 07:32:51 AM
Anyone figured out yet what to compile to make the hardware-clock work using a custom-kernel? Without paying any further attention to my kernel-options I am stuck with this: Code: abeir:~# hwclock --show The Hardware Clock registers contain values that are either invalid (e.g. 50th day of month) or beyond the range we can handle (e.g. Year 2095). abeir:~# date Sun Apr 26 14:31:09 UTC 2009 Oh... Marvell SoC RTC (CONFIG_RTC_DRV_MV) is compiled into the kernel.
