Can't boot rolling release on R76S

[ljones0]

Hello all!

 

Not sure what is going on at all but I'm having a problem booting the "rolling release" of armbian (debian 14/forky) minimal cli. I'm using a nano pi R76S with 4gb of RAM and 64GB emmc. 

 

I can successfully burn a microsd for the previous version  (also minimal cli vesion) which boots ok.However if I try to use the newer version nothing happens -- the red LED on the R76S stays permanently on and I get no display or any other life.

 

I did try using different microsd cards but it did not make any difference. I also tried using the same microsd (I wrote the older version first to the microsd which boots) then wrote again on the same microsd. 

 

I'm using the download page for the images from here - https://armbian.com/boards/nanopi-r76s

Hello,

 

Can you connect the UART to the NanoPi and see where it gets stuck?

I'll take a look at it over the weekend.

 

Thank you.

Will try to find my UART to USB and see what I get.

Ok, I gave it a go. I used the settings - baud rate 1500000, Data bit=8,Parity check=None,Stopbit=1,Flow control=None. Most of what I got was largely garbled but here's what I could read:

Thanks for sending the log.

This looks like an issue with the vendor U-Boot. We're planning to drop it this Sunday and switch to mainline U-Boot.
