		So pcm's command dd if=spiflash.bin of=/dev/mtd0 didn't work for you?

Can you try manjaro ? If it doesn't boot try this on SD card: Code: dd if=/dev/zero bs=32k seek=1 count=1 of=<microSD>(01-29-2020, 11:48 AM)tophneal Wrote: So pcm's command dd if=spiflash.bin of=/dev/mtd0 didn't work for you? I know there are people who succeeded. For me it didn't work. Had to use rkdeveloptool. Which is not big deal actually.

I attempted, but I do not know if I entered "microSD" correctly. I'm sorry for such a noob question, but could you please tell me how to find out what to put in "<microSD>"?

		Try lsblk command. 
	
	
	
	
In the output you should have mmcblk1 and mmcblk2. Identify your sd card by capacity and the device you are looking for will be /dev/mmcblk1 or /dev/mmcblk2. Do not destroy uboot on eMMc it will be one of the mmcblk devices.
