Prepare the SD card for the Minnow Board MAX

============================================

 1. Partition the SD card with a GPT partition table

    sudo cgdisk /dev/mmcblk0

    Create two partitions:

     a) First partition of a few dozens of megabytes, which will be

        used to store the bootloader and the kernel image. Type must

        be EF00 (EFI partition).

     b) Second partition of any size, which will be used to store the

        root filesystem. Type must be 8300 (Linux filesystem)

 2. Prepare the boot partition

    We will format it, mount it, copy the EFI data generated by

    Buildroot, and the kernel image.

    sudo mkfs.vfat -F 32 -n boot /dev/mmcblk0p1

    sudo mount /dev/mmcblk0p1 /mnt

    sudo cp -a output/images/efi-part/* /mnt/

    sudo cp output/images/bzImage /mnt/

    sudo umount /mnt

 3. Prepare the root partition

    We will format it, mount it, and extract the root filesystem.

    sudo mkfs.ext4 -L root /dev/mmcblk0p2

    sudo mount /dev/mmcblk0p2 /mnt

    sudo tar -C /mnt -xf output/images/rootfs.tar

    sudo umount /mnt

 4. Enjoy
