[U-Boot] amlogic a96 mini

[Belisko Marek]

Hi,

I'm trying to run mainline u-boot on amlogic a96mini device but before
I try to flash it does anybody have an idea if it will work on
mainline. As I have limited number of devices and I know that after
flashing I can brick the board so would like to ask if anybody have
experience with this device and running mainline. Thanks and BR,

marek

I would strongly recommend making
https://github.com/superna9999/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.

OK thanks for hint. IIRC this hdmi thingy tells FW from which media to
boot and then I can compile u-boot and have boot it from SDcard?
For me any amlogic u-boot is fine just need to be sure it will boot
from emmc in final step then :). Thanks.

Correct.  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 :)
