1. Mount your NFS share to /var/volatile/tftpboot:
mount -t nfs <host ip>:<nfs_root> /var/volatile/tftpboot
2. Extract the rootfs images into both root directories
a. tar -xf /var/volatile/tftpboot/smarc-image/core-image-sato-smarc-samx6i.tar.bz2 -C
/var/volatile/r1
b. tar -xf /var/volatile/tftpboot/smarc-image/core-image-sato-smarc-samx6i.tar.bz2 -C
/var/volatile/r2
3. Install the flattened device tree file:
a. cp
/var/volatile/tftpboot/smarc-image/uImage-imx6q-smx6-lcd-pcieswitch.dtb
/var/volatile/r1/boot/dbh.dtb
b. cp
/var/volatile/tftpboot/smarc-image/uImage-imx6q-smx6-lcd-pcieswitch.dtb
/var/volatile/r2/boot/dbh.dtb
4. Unmount the eMMC partitions:
a. umount
/dev/mmcblk0p1
b. umount
/dev/mmcblk0p2
5. Clear out the boot environment:
a. dd if=/dev/zero of=/dev/mtd1
