Solved the issue by writing an official U-Boot image to the onboard SPI flash using an USB-A to USB-A cable as descibed on the Radxa Wiki here.

Hi everyone,

I am having trouble to get my Rock Pi 4A to work with the latest LE 10.0.2 image [1] and my EMMC module. When I power on the board, the screen remains black, please find the output of the serial console in the attachments (apparently some words in it are 'censored' so I cannot post an excerpt here).

The board is at rev. 1.4 and was previously running Armbian. The problem seems to be related to the "LE on EMMC" combo somehow since

- the same LE image works flawlessly when written to an SD card

- other images (e.g. the Radxa Android image) work on EMMC, too.

Unfortunately I'm not familiar with the boot process of LE or this kind of device in general so if the serial output contains any clue, I'm not able to see it.

I would be grateful for any pointers that could help me resolve the problem (or even just a confirmation that what I'm trying to do was pointless to begin with).

Thanks!
