My eMMC boot issue


I got my RockPI4A yesterday, sorry for the noob question.

I can boot debian from SD card without issue but it will not boot from eMMC.

I have flashed the MMC with dd=

If i run ‘sudo parted -l’, I am shown an error ‘‘Warning: Error fsyncing/closing /dev/mmcblk1rpmb: Input/output error’’

I’m not sure what that mmcblk1rpmb partition is, I flashed with the same image as the SD card but there is no ‘‘mmcblk0rpmb’’

If I remove the SD and power on, the screen remains black and the blue led remains on 100% of the time.

Spi is installed on mdt0, should I erase this? Will it then boot from the eMMC or will this brick the device?

Any advice would be welcome. I’ll keep looking

mmcblk1rpmb is not for user usage. You can learn more about eMMC on:

use parted /dev/mmcblk1 instead.
