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_rwif [ ! -e /dev/mmcblk0p1 ]; then
sfdisk /dev/mmcblk0 << EOF
, 1G
, +
write
EOF
mkfs.ext4 /dev/mmcblk0p1
mkfs.ext4 /dev/mmcblk0p2
fi
Any help would be greatly appreciated.
Please refer to the attached document, especially, to the Section 4.3 "Preparing an SD/MMC card to boot".
Have a great day,
Artur
