Hello,
Thanks for the link. But Nano PI NEO 2 is a 64 Bits board (Allwinner H5 vs H3) and does not have emmc.
Flash driver is present:
armv7# modstat flash
NAME CLASS SOURCE FLAG REFS SIZE REQUIRES
flash driver builtin - 1 - -
But flash device is not detected
armv7# disklabel /dev/flash0
disklabel: /dev/flash0: Device not configured
Regards
