The Rockchip boot ROM requires a particular file format for booting from NAND:
It starts with 512-byte, rc4 encoded header and is aligned to nand page size
Then first 2KB of first stage loader (tpl) aligned to nand page size
n empty pages
second 2KB of first stage loader (tpl) aligned to nand page size
n empty pages
...
first 2KB of second stage loader (spl) aligned to nand page size
n empty pages
second 2KB of first stage loader (spl) aligned to nand page size
n empty pages
...
Size of spl and tpl must be aligned to 2KB.
example usage for nand with page size 16384 and one empty page in iteration:
# mkimage -n rk3066 -T rknand -d ./u-boot/tpl/u-boot-tpl.bin:./u-boot/spl/u-boot-spl.bin -X 16384,1 outSigned-off-by: Paweł Jarosz paweljarosz3691@gmail.com
