Hi,
I downloaded android 7.1 sdk and compiled them.
Then I create update.img using mkupdate.sh script and burned it micro sd card.
However, Android did not launched correctly. And below messages are displayed.
( I used some micro sd cards, but the result is same)
failed to mount /cache (Block device required)
format_volume: make ext4 failed on /dev/block/rknand_cache with
failed to mount /cache (Block device required)
fauled to moutn /metadaba
format_volume: make ext4 failed on /dev/block/rknand_metadaba with
failed to mount /metadata
I did not understand the cause. Does anyone know the cause?
