Prepare the SD card for the Minnow Board
|
||||
========================================
|
||||
|
||||
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.ext3 -L root /dev/mmcblk0p2
|
||||
sudo mount /dev/mmcblk0p2 /mnt
|
||||
sudo tar -C /mnt -xf output/images/rootfs.tar
|
||||
sudo umount /mnt
|
||||
|
||||
4. Enjoy
