[philwzen]

hi I have a few duos , two of them appear dead but when you monitor the debug serial port holding down the reset button at power up they display

U-Boot SPL 2017.05 (Jul 10 2017 - 11:16:21)
BOARD: Nanopi Duo id=4
DRAM: 0 MiB
### ERROR ### Please RESET the board ###

it seems that the onboard memory has died

Got such a problem with 1 of my 8
OrangePi One.

I also got there the ouput from the bootloader and then nothing

Do you have access to a hot air re-work station?

It might be nothing more than a bad connection on one of the BGA balls.and a reflow of the memory chips might work. No guarantee but worth a try if you have access to one.
