Follow the below steps for flashing the rootfs into eMMC,
- mmcblk0boot0 is boot0 partition/raw partition where the bootloader will be placed in emmc boot mode and mmcblk0 is where filesystem and kernel binaries are placed.
- After the bootloader is flashed, directly flash the rootfs.wic file to mmcblk0 using below commands.
#Copy the rootfs.wic file to SD card and keep in /home/ directory.
$ sudo dd if=/home/rootfs.wic of=/dev/mmcblk0 bs=4M conv=fsync
- As part of wic flashing, emmc (/dev/mmcblk0) will be formated into fat and ext4 partition, the uEnv.txt file will be available at FAT partition. With help of uboot load commands env variables are imported from uEnv.txt file after uboot is booted.
