Hi,

I was able to perform serial communication (uart1, uart2, uart3) on Orange Pi PC with the arbiam operating system.

Now, I need to perform the same communication using another operating system (Debian or Ubuntu). I can not set the pins on uart.

Anyone have any tips?

thank you

Att,
Rafael

Why are you not sticking with Armbian ?

 

Armbian does not support the driver we need (TV adapter)

Then, you will need to tweak either DTS on Mainline or FEX on Legacy to enable those UARTs.

 

Yes, more on debian or ubuntu does not have the script.bin file ..

How would it be to change the DTS?

The screenshot you've provided confirmed that it is Legacy, so no need to change any DTS.

Unfortunately, I can't help on Legacy ... Maybe someone else can help ...

 

And it looks like one of "official" Orange Pi distributions, so better post on their forum - most people here have no iea how do they manage different script.bin configurations.

You mean composite TV out? It's supported by default - check forum for advanced adjustment if needed. If you are talking about some 3rd party TV tuners, stock kernel will have only less support than ours. Even better support in TV tuner area you will achieve with modern kernels, but they are still in development stage ... "use at your own risk".
