How to enable UART1 on Orangepi PC with Armbian Buster 19.11.6

[Gustavo dos Anjos]

I have an Orangepi PC with OS: Armbian_19.11.6_Orangepipc_buster_current_5.4.8_desktop... I'm trying to communicate hardware through the UART1 ports (GPIO198 and GPIO199, respectively pins 8 and 10), but I'm not able to enable the ports, I've tried modify the file "un8i-h3-orangepi-pc-plus.dtb" but I couldn't, I also tried the solution proposed in this topic: https://forum.armbian.com/topic/1524-orange-pi-one-how-to-enable-uart/ but I couldn't find the script.bin file in the boot folder... I also tried using Minicom, and the message Offline appears. I need to activate UART1 and configure it with 19200,8,1,N. Any tips?

First thing I notice, is that's quite old version of Armbian, can you upgrade?

How do I do that? Do I install a new version on another SD? Found this one: Armbian 22.02 Bullseye, is it compatible?

Generally speaking, yes, just burn to some other sd card and try to boot it and see if the new version works.  Follow instructions in documentation.  Whatever latest version is for that board, which can be found on download page.

 

I don't own this hardware, I am assuming it will boot from inserted sd card first, but some devices don't work that way (most do).

Hi @Gustavo dos Anjos,

Where you able to get this working? I have a similar issue with OrangePi One
