  1. How to configure headless similar to the instructions in HardKernel's Wiki? https://wiki.odroid.com/odroid-xu4/application_note/software/headless_setup?s[]=headless#change_resolution_in_xorgconf I'm guessing the device is different?... Also what wold be the rest of the xorg.conf settings? The wiki page only shows the part that should be modified. Thanks.
  2. Odroid-C2 (there was no adequate tag) After I upgraded my ssd install from 23.11.1 to 24.2.1, the board didn't boot. When starting 24.2.1 from a fresh sd card, usb and disk leds are on, and the board boots. But they don't show in lsusb. If I reconnect them after the board is booted, the leds stay off (and obviously they don't show in lsusb). Of course, booting from external ssd stops at some point, because usb is lost during the boot (when connecting a display, the failures start to happen on armbian services). Had to restore previous release 23.11.1 from backup on my ssd. Everything works again.
  3. Odroid C2 never starting after a soft reboot (reboot command). I have the same problem which other user is having with the Odroid C4 With the last kernel I have 5.10.102-meson64 the Odroid C2 never boots again after the "reboot" command, I need to unplug and plug again the power suply. Thanks and best regards, David
  4. hy guys is it possible to boot the odroid c2 from usb? so i can connect a ssd (M.2 SATA) via usb connector and use this. thank you
  5. Hello community, I'm a beginner with all that kernel and modules stuff, so please be kind, if I am asking stupid questions. My plan is to install a Hifi-Shield on my C2, but so far had no luck: modprobe: FATAL: Module snd_soc_pcm512x not found in directory /lib/modules/ Found out, that some modules are present under /lib... e.g. /lib/modules/5.15.0-105-generic/kernel/sound/soc/codecs/snd-soc-pcm512x.ko (cave:this is example from my ubuntu I'm writing on) some other modules are in fact missing. I found similar modules here: https://github.com/3isenHeiM/HiFi-Shield-Plus/blob/master/sound/soc/aml/m8/snd-soc-odroid-dac.ko Is it possible to integrate those modules in actual kernel environment and what do I have to do to make them activated (I think, that is what modprobe does!?) Regards 3MF
  6. I needed a kernel upgrade to be able to run some applications. I value stability over cutting edge features so I decided to try the Debian image. However I detected a few things that are not working properly. 1. USB almost never works. Most of the time my very plain USB keyboard won't be detected. There is an error message right at the start of the boot sequence "Failed to get keyboard state from device[...]". I have to shutdown and start multiple times by plugging off the power cable and I also keep trying different USB ports. Some rare times the keyboard will work though, even with the above error message. Even rarely I don’t see the error message at the boot start ( I get a confirmation that the keyboard was detected). This of course while the keyboard is plugged in before connecting the power plug. I found this comment but clearly the problem now is not plugging in the USB cable after booting. Also there is a mention about a note on this requirement in the downloads page, but I wasn’t able to find it? Then after I managed to setup the basics, I found this recent thread and I would like to know if the suggested fix is the recommended solution. Also I removed the J1 jumper from the board after reading in the official product page that I should remove it to save power in case I don’t use the USB OTG port for power supply (I use a dedicated power cable via the small round connector between the HDMI and the Ethernet ports). Also, would removing or placing the jumper matter for this case? 2. The first time I installed the Armbian image I must have made a mistake and the language got set to my local language, but I prefer English. I tried to change this using 'armbian-config' but it wouldn’t stick. I could see the changes on screen after I made my selection, but if I exited and started the config tool again, it would show the default value again, instead of my previous choice. The only way I could see the changes taking effect was after I followed the instructions here, specifically the BASH script in xinitrc . At this point the language issue was fixed but the home folders were not in English, so I figured it wouldn’t take long to try a fresh setup again and so I etched the image again and this time the correct settings were applied. But the issue of not being able to change locale via the tools provided should remain valid. 3. I installed X11vnc to access remotely the same desktop I would have with a monitor connected to the C2. This was the setup I had before with the official Hardkernel images and this was working properly. The issue now is that with a monitor connected I do get via X11vnc the same screen (showing the Armbian Linux penguin), but if I reboot with the monitor disconnected I get a very small window insted, and this time with the xfce wallpaper. I can resize this window with the ratio settings in the control panel, but what I would really like is to have the same desktop, whether a monitor is connected or not, as I had before. I noticed the installation doesn’t create a Xorg.conf file, and I don't want to start tinkering by myself because I need the machine in working condition atm. I found these instructions that involve using a dummy monitor setting, but I am unsure if this would yield the result I’m looking for. If someone is able to provide good directed advice I would prefer that than start changing settings without really knowing if they are going to fix the issue or not. 4. The network connector shows a notification on the top right corner about the wired connection and a button offering the option to not show the notification again, but the button doesn’t do anything and I get the notification again after every boot. Does the Ubuntu image handle these issues better? I could maybe post this in 4 separate threads if it would be better to follow up on the discussions? Thanks.

  8. I have two Odroid C2s. One I have been using as NUT server for Eaton UPS. Today NUT clients report no connection. What seems to be the problem is the C2 (this happens with both, same SD card) are not seeing devices plugged into USB ports so the USB connection to the UPS is not working. I have verified the Eaton and USB cable are fine. I regularly update the C2 I wonder if a recent update has affected the USB port functioning? Any way to troubleshoot? I tried a few USB flash drives and then lsusb but none are seen.
  9. Hello I tried to retasrt my system, but it doesn't work. Before i post my question i found this thread: i can't find a solution in the thread. Does anybody knows, how he fixed it? I need to restart the system. Can i disable the user login to the beginn? i need to start without a login choice. Thank you

  12. So I've had an odroid C2 running Armbian for the past couple of years without a hitch. Today however, when I try to login to my box either remotely or directly, I'm greeted with a login screen. On this box consists of 4 accounts (all mine) and I've set my primary account to automatically login when booted (never needed a password). Yet still, I'm greeted with the login screen. I try to login under my other accounts using my password, but even then, screen goes black for a second, then back to login screen. I really need some help here. As I said, I've been running Armbian flawlessly up until this point, now all of a sudden I can't even login to any of my accounts? Thanks in advance.
  13. Hi, I tried to migrate my odroid C2 form corelec to armbiam bookworm but i'm having some problems with network... i need to fix on switch the limit bandwith at 100mb/s even impossible to have network... When it's ok, if i tried to force config with ethtool (network freezes everytime)... and in every case, after some hours.. the network freeze.. So i'm looking for an armbian with a good stability and not too old.. Regards,
  14. Hi, I downloaded the jammy xfce image for ODROID C2 today: MD5SUM 033fbc0babb56db5388b4c707a2fc0ce Armbian_23.11.1_Odroidc2_jammy_current_6.1.63_xfce_desktop.img.xz After flashing it onto my SD card with xzcat and dd, I tried to boot with my Odroid C2 ending up with this error message: ALERT! UUID=75e23441-f5ee-4479-a484-7060ccd898ae does not exist. So I put the SD back into my PC and checked with gparted: the UUID of the partition that I have on my SD card seems to have exactly the UUID that was not found. In fact the boot until that error message lastet quite long, so I expect that the timeout is not too small. Does anyone have an idea? Thanks!
  15. Hi there, I have a working armbian jammy on my odroid c2, but I'm unable to get SPI to work. I tried to load the three as described in the odroid wiki (https://wiki.odroid.com/odroid-xu4/application_note/gpio/spi#tab__odroid-c2😞 sudo modprobe spidev sudo modprobe spi_gpio sudo modprobe spi_bitbang ...and that works, but unfortunately no device file is created. I believe SPI needs to be enabled somewhere additonally. In the "armbian-config" hardware section, there is only an entry for the odroid n2, which does not help/work for me. Are there any other hints somebody can give me to make it work? thanks a lot! sg
  16. Hello Today i have a problem, which i had sometimes randomly. But today i'm at home, so i can connect the odroid via hdmi port. The error message is: kernel panic..... sorry, but i only can make a picture from the monitor. This is the picture: thank you a lot
  17. Hello experts I'm a newbie and use my ofroid as server (mysql, iobroker, go2rtc) This need a lot of ram. So i try to reduce all service which i don't need. I disabled the gui (desktop) and ise only ssh. I use zram to be faster. Is there any other service which i can deactivate?
  18. Hello i have armbian on a 64gb sd card. The card works not so good and has 64gb i would like to move my full distributuion with all configs(wireguard, ssh, ftps, iobroker, ufw, etc) on a new 32GB card. how can i transfer it without losing data? Thank you!
  19. Hello I tried to shrink my sdcard (64gb, 17gb in use) and copy it to a 32gb card. I found a tutorial, but it don't work I fownloaded gparted and create a bootable device. The instruction 1.resize2fs /dev/sda1 [new size of the partition] in my case the original card is sdc1 2. Copy the shrinked device to the new device dd if=/dev/sda of=/dev/sdb In my case dd if=/dev/sdc of=/dev/mmcblk0 Is it really correct to use it without the "1" ? Sda, not sda1? However It didn't work.... Gparted gui shows me, that the original sd card has the original size 58.24gb. But I shrinked it to 27gb..... with resize2fs /dev/sdc1 27000M So I use gpated gui, by right click on device and select change volumesize. This worked, now I shrink the partition to 17gb. So looks good. After this , i tried dd if=/dev/sdc1 of=/dev/mmcblk0 to copy the partition. The odroid not boot, when I insert the card. Thd card hasn't a partition table, maybe this is the fail. So I do it again, but create a partition on the new sdcard, before i copy the old files on it. When I copy the files with dd, i will lose the partitions table. What is the fail Should i try to copy the full card to the new card Remember: on the new card is one shrinked partition with my armbian (17gb) and the rest of the card isn't as a partition. Thank you
  20. Hello. I use jammy ambrian on my odroid c2. In this is a 64gb sdcard. 60% of the card is empty. Can i create a automatically backup on the card? It would be nice to restore the fullsystem if something go wrong and the system crah. At this time i crate all 4 weeks a full sd backup on my other computer. but it need a long time, because the full 64gb will be safe as a .img file, which i can restore. Is there a solution to get a smaller zip file, withe the full system???? Thank you a lot. If the fully system zip is not to great, i can upload it on my cloud..
  21. Hi, So I found out the hard way that neither jammy nor bullseye builds for odroid c2 actually allow ssh at first boot My board is headless, but has a wired connection to my lan and always gets assigned the same address. Which file or files do I need to edit to ssh into it without having to do initial setup first, please?
  22. Hello I use a odroid c2 und create a full img backup. Can i use this in a newer odroid like too? I have some programms etc on it and don't want to reinstall it.
  23. I've tried a few images of the latest builds. None of them start. Odroid starts to power the screen and I see blinking lights, but screen goes dark and it seems to cycle like this. I use USB power for it and a powered hub (so basically no power output to USB dongles, etc.)
  24. Hallo my odroid C2 shutdown during the night. i can see it always on the next day, when the ssl connection is disconnected. Is there any log file, where i can see, if there was any problem? thank you
  25. Hello I use armbian on my odroidc2 on the devic is lamp, for a mysql and php server. Now i tried to install composer. The installation works great, but i can't use any scripts from vendor folder. The directory of my php file: /var/www/html/terminal/includes/helpers/my_php_file.php the code in my php file require_once(__DIR__ . '/vendor/autoload.php'); The code means the vendor directory has this path: /var/www/html/terminal/includes/helpers/vendor/autoload.php But thats not correct. I searched and found the correct path of composer it's: /home/user/vendor/ So i tried to make a folder-shortcut in my www/html/ folder, but i can't use it because permission denied. Next idea: i fix the code in my php file include '../../../../../../home/odroid/vendor/autoload.php'; now it would be found, but i get the same error: Warning: include(../../../../../../home/odroid/vendor/autoload.php): Failed to open stream: Permission denied in /var/www/html/terminal/includes/helpers/backup_DB.php on line 26 what's the correct way to youe composer with autoload.php and something more?
