**** BEGIN LOGGING AT Fri May 25 02:59:59 2012 May 25 16:11:59 ogra_: hey May 25 16:14:05 ogra_: I tried to clone the 12.04 installation after installing my daemon on the pandaboard, but when the replicated sdcard boots up, the system cannot realize the /dev/ttyUSB* ports with usb-serial and modems on those. May 25 16:14:43 What can cause this ? If I use the original sdcard, then there are no such things happening. Is there any idea I could try out for repearing this before I begin the looong replication procedure again ? May 25 16:17:43 how are you cloning the SD card? May 25 16:18:06 dd May 25 16:18:25 I am cloning the content obviously, not the physical device. ;) May 25 16:18:49 you're just dd the entire card and not just a single partition correct? May 25 16:18:59 the entire sdcard May 25 16:19:18 first onto my usb pendrive, and then back to the other May 25 16:19:26 ok, oh and you did make sure to change /etc/fstab to not use a UUID on the root partition mount, right? May 25 16:19:30 that is why it is so long. I have not taken an image onto my hard disk of the laptop yet. May 25 16:19:57 TypoNAM: I am unsure how that is related to the /dev/ttyUSB* problem. May 25 16:21:14 hmmmm May 25 16:21:19 what is the name of the kernel package ? May 25 16:21:23 I would try to reinstall the kernel. May 25 16:21:40 since this is a kernel task. May 25 16:21:58 http://lxr.free-electrons.com/source/drivers/usb/serial/pl2303.c?a=arm -> this driver, precisely. May 25 16:22:02 so it boots up just fine and you can access the shell without any problems? May 25 16:22:07 yep May 25 16:22:15 I am now behind ssh over the ethernet port May 25 16:22:35 usb ports are not really recognized with usb-serial pl2303 cables at least. May 25 16:23:09 udevadm monitor& shows kernel messages while plugging those in though May 25 16:23:14 just no /dev/ttyUSB* created. May 25 16:23:31 if I use the same environment, but the original sdcard, everything is alright. May 25 16:23:40 strange May 25 16:23:57 indeed May 25 16:24:03 so what is the kernel package name ? May 25 16:24:10 Perhaps a simple reinstall of that fixes this very issue May 25 16:24:36 checked dmesg? May 25 16:24:56 about ? May 25 16:25:06 dmesg | less and see if there's any errors reported related to driver failures May 25 16:25:16 dmesg checks usually end up seeing something not telling anything to an average user that can be used for repearing. May 25 16:27:10 the only things I can think of by cloning an sd card to another sd card and it failing to work is: / failed to mount due to UUID being different in fstab, or you didn't do a complete clone, meaning contents at the end of the sd card failed to copy because the end of the destination was reached May 25 16:28:22 when you used dd, did you clone to an image file on your Linux workstation then dd that image on to the sd card, or did you do a literal dd from sd card to the other sd card? May 25 16:36:34 TypoNAM: I do not have two sdcard slots May 25 16:36:49 TypoNAM: as I mentioned above, I used an interim usb pendrive for the transferring. May 25 16:38:04 eeek, ok I missed that part then May 25 16:38:35 why did you use a pendrive instead of as an image to a hard drive instead? May 25 16:39:07 TypoNAM: why wouldn't I ? May 25 16:39:26 Using hard disk space for 4 GB requires 4 GB free space on the hard disk... May 25 16:39:41 not to mention, way harder to carry that way to my colleagues May 25 16:40:36 here's what I do when I clone USB drives and sd/mmc cards: dd if=/dev/SrcDevice of=myClonedDrive.img bs=512K then writing that image back on to an actual device: if=myClonedDrive.img of=/dev/DestDevice bs=512K May 25 16:41:08 Like I said, that is unacceptable in my case. May 25 16:41:20 because of two very important reasons. May 25 16:41:36 not to mention, usb pendrive should work anyway May 25 16:41:54 well because 4GB != 4GB on SD cards that are not exactly the same model, much less across different mediums, in this case an SD card to thumb drive May 25 16:42:52 huh ? May 25 16:43:40 case in point, I have two 8GB sandisk SD cards, one is actually 104MByte / 212992 blocks less than the other 8GB cause the one that has less blocks is newer than the other one. May 25 16:43:56 they are totally the same sdcards May 25 16:44:59 but your USB drive is not if it isn't more than those SD cards as it could be the one causing the transfer cut off point cause dd reached end of file on destination May 25 16:45:12 it is totally bigger May 25 16:45:13 8 GB May 25 16:45:18 so + 4 GB ... May 25 16:49:50 insert your sd card into your Linux workstation and then do: parted --list /dev/SDcardDevice May 25 16:50:04 then remove it and insert your other sd card, and see if they're matching May 25 16:50:12 they do. May 25 16:50:22 I have checked those things after flashings. May 25 16:50:36 and to be honest: if they did not match, there would be way bigger issues than just /dev/ttyUSB0 May 25 16:51:00 aye, kernel reinstall helped. May 25 16:51:13 nice :) May 25 16:52:25 if I were you I wouldn't be too happy, because if a reinstall fixed it then who knows what else is corrupted on that card, I wouldn't trust it what so ever May 25 16:53:22 wouldn't happy with a fix ? :o May 25 16:53:33 In fact, I am super happy about it. May 25 16:59:34 Hello! I used ubuntu-11.10-preinstalled-desktop-armel+omap.img image on BeagleBoard B4 and I'm not able to use any usb-storage device.http://pastebin.com/V2sdn3XM http://pastebin.com/tnD1QqDS Both the BB and USB hub are externally powered. Am I missing something? May 25 18:08:33 ppisati: Hi May 25 18:32:34 the arm cross-compiler can't build the kernel for me anymore May 25 18:32:40 /usr/bin/ld.gold.real: error: scripts/genksyms/parse.tab.o: incompatible target May 25 18:32:51 i tried make clean May 25 18:33:20 CONFIG_CROSS_COMPILE="arm-linux-gnueabi-" May 25 18:47:59 /usr/bin/ld.bfd.real: scripts/mod/modpost.o: Relocations in generic ELF (EM: 40) May 25 18:48:22 i tried checking out back to 3.4 but that didn't do it eithe May 25 21:28:09 ogra_: horrible horrible laptop - http://www.frys.com/product/6515793?site=sr:SEARCH:MAIN_RSLT_PG May 25 21:40:23 prpplague: so, other than being preloaded with Windows 7, what else is wrong with it? May 25 21:42:24 GrueMaster: it has a quirky bios called H2O bios, and it HATES linux May 25 21:42:58 ouch May 25 22:13:26 H2O? Heh May 25 22:52:36 definitely not arm.... **** ENDING LOGGING AT Sat May 26 02:59:57 2012
