Allard Krings If mmc list shows more than one mmc device you might need to try the second device. I think this is the issue here but I could be wrong!

Allard Krings Hello, I believe the main difference is there is a different device tree for the older boards. I would take a look at the Ubuntu wiki, there’s a note near the end for 1.2 boards: https://wiki.ubuntu.com/RISC-V/StarFive%20VisionFive%202 Unfortunately I can’t test this as I have a 1.3 board, but with any luck this will help. I would also suggest ensuring you are on the latest board firmware, or use Ubuntu’s fork of the firmware (details on the wiki link above). Please do let me know if you manage to solve this as it will be helpful for anyone else facing the same issue. Thank you!

Tom That's interesting, mine is running the latest official firmware and it seems to run ok, though I will give the ubuntu fork a try and see if there are any differences :)

Hey that’s pretty weird, I haven’t seen that error before. Do you perhaps have a different revision of the board? Mine is a v1.3b

Thank you 🙂
