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
