Use armbian-config to enable UART4.

 

 

Sorry, I can't find out how to open UART4. This is the screenshot of my Armbian-config, and there is no option of "hardware" in it.  I use the latest version of the system, which can be seen in another screenshot for details.

Hm I though there should be a menu entry called "hardware" to enable various overlays...

Since it is media kernel @balbes150d

Got an idea if overlays are missing or something? Thanks

The overlay works normally in a running system.

See this topic. The kernel already has everything, you only need to add the necessary overlay immediately in a working system.

No complicated steps with old u-boot scripts are needed. You can change everything on the fly in a running system.
