Boot from eMMC M4 v2
Posted: Sat Dec 07, 2019 9:27 am
Hi all, I am trying to boot my M4 v2 from the eMMC card without success. It boots perfectly from the sd card but ends up at a initramfs shell when trying to boot from the eMMC card. I think it is looking for /dev/mmcblk0 which I believe is the sdcard - any ideas how I can get around this ?

I am no expert for NanoPI.
But in general LSBLK helps, as it lists all available block devices.
If you cannot execute it from initramfs just issue it when you booted from SD. eMMC must be attached though, else it won't be shown.
Since MMC and SD are dealt with similar by udev, it probably is /dev/mmcblk1?
The problem might be located somewhere else. In this case I cannot help, since I don't have a NanoPI (yet).
