I have a feeling this was caused by a p[roblem with the definition of ftdfile variable:  

 

line from boot.cmd:

load ${devtype} 0 ${fdt_addr_r} ${prefix}dtb/allwinner/${fdtfile}
 

from the serial output:  File not found /boot/dtb/allwinner/allwinner/sun50i-a64-pine64-plus.dtb **

note the duplication of Allwinner. 

 

Since I couldn't  find where it was defined ,  I just copied the allwinner directory into itself.....:-)  which fixed the problem.  Perhaps someone could look into this?

thanks.

 

 

Same problem here. I'm pretty happy to go into this, but don't have a clue how uboot and the device tree overlays work. I guess it's something with an image being created where file references are wrong, but no idea what type of image, how it's created, etc.

see the last post in this thread for a fix
