No matter what I do, when I use an Armbian image built with compile.sh I get a blank orange screen on the OPi Plus 2. The downloadable pre-built image from Armbian for the board works fine. Wanting to debug this, I have an Adafruit UART serial cable adapter, known functioning and working. If I attach this to the UART pins on the small header near the power socket I get no output (and I have swapped RX and TX to no avail).

 

How does one enable this UART? Am I using a wrong approach? I have

console=both

in armbianEnv.txt.

 

 

UART is enabled by default. Which image are you trying to build?

Builduing any Armbian image, headless or desktop,  for any of the Orange Pi series results in a blank orange screen on boot and no futher action. The UART outputs nothing. However, the downloadable prebuilt Armbian image does work.

 

As to the UART problem, I am beginning to suspect a board hardware problem. As to the non-booting issue, I have no idea. I did observe that I could find the IP address and ssh into the machine despite this lack of display output. Are there logs I could find to help diagnose this issue?

Board configurations, u-boot configs can be sometimes broken upstream for a single board. This can lead to boot failure - has to be investigated.
