- boot.bin

Partition table: msdos (gpt won't work) Format into 2 partitions: FAT32 and EXT4 (use gparted or command line instructions below), the order of partitions is important or change bootargs in the device tree accordingly.
FAT32: copy the following files:
- - boot.bin
  - u-boot-dtb.img
  - devicetree.dtb
  - uImage
If EXT4 is not empty - format it or delete old contents
Mount EXT4 to some <mountpoint>
