I am using Yocto to generate the required files to get my iMX6 VAR SOM Solo up and running. I have no issues with generating these files or anything but I am wondering what I need to do to format and partition the eMMC prior to loading the files onto my board.
I have a bash script which does this by sfdisk and mkfs.ext4 commands however this script is run after the system has initialised.
mkdir -p /tmp/emmc_ro
mkdir -p /tmp/emmc_rw
if [ ! -e /dev/mmcblk0p1 ]; then
sfdisk /dev/mmcblk0 << EOF
Any help would be greatly appreciated.
