Hi @AaronNGray, Did you check if there is indeed an SD card inserted? If so, try to remove it then re-insert it while the system has booted. Also, seems that you have an NVMe storage device attached, on which the OS was installed - not the SD card as you mentioned? As @laibsch mentioned, the eMMC is detected and available as /dev/mmcblk0, but seems that SD card is not seen (if it was inserted). Grt,

First test was in a CLI environment so running fullscreen. Self built with no media related changes to the configuration. Edge build around kernel 6.15.0 and running on Pcduino2 For the second test I used the build scripts to create a desktop image which came to be less of a headache because less dependencies had to resolved than working purely with CLI only. This was built around kernel 6.15.4 and running on Pcduino3. This time got a blue screen within the window and lots of errors relating to dmabuf. test2.txt I currently have CMA set to 64mb, although this is overridden by the shared-dma-pool within the sun7i-a20.dtsi

Hi @C127, any progress on the DTS?

Probably worth a shot - I had an install one time that gave me fits at initial boot. For giggles I expanded the FS using Gparted in linux to fill the entire card. It solved that problem for me.

Hi Armbian folks, I’m new to the forum and joined today (07:42 PM CEST, July 20, 2025). I’ve recently started playing around with single-board computers, like an Orange Pi 5 I set up with Armbian a while back—it’s been a fun challenge! I’m based in Poland and enjoy tinkering with tech in my spare time. I’d love to hear what brings you all here—any cool hobbies or projects you’re working on? I’m thinking of trying something simple like a media server or smart home setup, but I’m open to ideas. What do you enjoy doing with your SBCs or other gear? Looking forward to chatting with you!
