The previous stages will check and then if it sees the magic continue to boot process from other media. This will prevent you from bricking the hardware :) -- Tom signature.asc Description: PGP signature

For me any amlogic u-boot is fine just need to be sure it will boot from emmc in final step then :).

Thanks and BR, I would strongly recommend making https://github.com/superna/linux/wiki/Amlogic-HDMI-Boot-Dongle as a back-up. While I have before managed to interrupt a re-flash cycle such that the DTB on-board is still there and so the binary portions of the firmware are happy it will then load U-Boot from SD card. I did not play with mainline however. -- Tom signature.asc Description: PGP signature
