Josua Mayer 741ce3084e mx6cuboxi: fixup dtb ethernet phy nodes before booting an OS SoM revision 1.9 has replaced the ar8035 phy address 0 with an adin1300 at address 1. Because early SoMs had a hardware flaw, the ar8035 can also appear at address 4 - making it a total of 3 phy nodes in the DTB. To avoid confusing Linux with probe errors, fixup the dtb to only enable the phy node that is detected at runtime. Signed-off-by: Josua Mayer <josua@solid-run.com>		2022-06-14 21:25:26 +02:00

How to use U-Boot on Solid-run mx6 Hummingboard and Cubox-i
-----------------------------------------------------------

- Build U-Boot for Hummingboard/Cubox-i:

$ make mrproper
$ make mx6cuboxi_defconfig
$ make

This will generate the SPL image called SPL and the u-boot.img.

- Flash the SPL image into the SD card:

sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

- Flash the u-boot.img image into the SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Insert the SD card in the board, power it up and U-Boot messages should
come up.
