rkosegi Posted January 9, 2023 Share Posted January 9, 2023 How to run Armbian on Odroid C4? I followed official guide (https://docs.armbian.com/User-Guide_Getting-Started), but I always ends up with following: Gave up waiting for root file system device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Missing modules (cat /proc/modules; ls /dev) ALERT! UUID=e614931e-7b37-40f0-8d34-c3ca836004e8 does not exist. Dropping to a shell! SD-Card is working fine when other OS is used (such as Ubuntu provided by Hardkernel) Am I missing something? 0 Quote Link to comment Share on other sites More sharing options...

atone Posted January 9, 2023 Share Posted January 9, 2023 Multiple causes are possible, don't know how to help further. Hope someone more knowledgeable will help. 0 Quote Link to comment Share on other sites More sharing options...
SokTi Posted February 6, 2023 Share Posted February 6, 2023 Same issue here on HC4. When I'm pulling the SD Card and putting it back into reader while the loader is waiting for the root filesys, it continues the boot process 😕 0 Quote Link to comment Share on other sites More sharing options...
SokTi Posted February 7, 2023 Share Posted February 7, 2023 @rkosegi did you try using an older image like 22.08.1? That works for me with exact same HW. Then I was currious and tried a distro upgrade to 22.11.1 (6.02.y) and the boot issue came up again. Ended with 22.11.1 Bullseye 5.19.y on SSD and boot from SPI. 0 Quote Link to comment Share on other sites More sharing options...
frontrange Posted February 20, 2023 Share Posted February 20, 2023 I also have an hc4, and after messing with this for a few hours have been unable to get any of 3 sd cards to boot armbian, although each work fine with the Odroid Ubuntu image. Unfortunately, I don't have a serial cable so all I can tell is that the blue LED flashes, but I get no video from HDMI, nor does the MAC address come up ever on anything but the factory Ubuntu image. I've tried every 22.11.1 image, CLI and desktop, same with every single one of them. Is there any image available that has a version 5.X kernel that works anywhere?? 0 Quote Link to comment Share on other sites More sharing options...
frontrange Posted February 22, 2023 Share Posted February 22, 2023 (edited) Disregard mine. I was somehow thinking that Armbian would act like the OEM images, but it doesn't prioritize plumbing a headless system. I was expecting a sshd and thought the system was down when it was just throwing an unsupported video stream to the console waiting for input. I know, dumb.

Lobosito Posted March 19, 2023 Share Posted March 19, 2023 I replied to an older thread from last year regarding this same problem after I stumbled across this problem with the 23.02.2 Jammy XFCE image. I did some experimentation with various parameters and responded to that old post. In any case, I got it working using a different SD card. If you are interested in what I did, check out the post titled [Odroid-C4] Alert! Root UUID does not exist. Dropping to a shell! 0 Quote Link to comment Share on other sites More sharing options...
