Re: Booting 9 on odroid-c1

[Jared McNeill <jmcneill%invisible.ca@localhost>]

You need a new U-Boot that can deal with start address 0 images.

Source: https://github.com/jaredmcneill/u-boot-odroid
Binary: http://www.netbsd.org/~jmcneill/u-boot.bin.odroidc1

You also need to load the board's dtb and pass it to the kernel:

  setenv bootcmd "fatload mmc 0:1 0x21000000 netbsd.img; fatload mmc 0:1 0x20000000 meson8b-odroidc1.dtb; bootm 0x21000000 - 0x20000000"

HTH,
Jared
