== Installation ==

At this point, you must install U-Boot to flash yourself.

STM32MP1 series processors can boot from SD card or eMMC, which must
contain a GPT partition table with at least the following partitions:

  Nr |   Size | Label | Flags
  ---|--------|-------|------
   1 | 256KiB | fsbl1 |
   2 | 256KiB | fsbl2 |
   3 |   2MiB |  ssbl |
   4 |      * |     * | boot

U-Boot can be written to the SD card using the following commands:

  dd if=/usr/lib/u-boot/BOARD/u-boot-spl.stm32 of=/dev/mmcblkXp1
  dd if=/usr/lib/u-boot/BOARD/u-boot-spl.stm32 of=/dev/mmcblkXp2
  dd if=/usr/lib/u-boot/BOARD/u-boot.img of=/dev/mmcblkXp3
