May 20, 20251 yr When using armbian-config to select an overlay ("DTO001")e.g. for uart2, one is offered the full names w/ overlay prefix, e.g. sun7i-a20-uart2. The system adds this to armbianEnv.txt: overlays=sun7i-a20-uart2 But it has also the line overlay_prefix=sun7i-a20 In the end, uart2 is not activated (no output from /dev/ttyS1) - after changing the overlay line to overlays=uart2, I can read from /dev/ttyS1. System is Armbian 25.2.2 stable (bookeworm), Armbian Linux 6.12.20-current-sunxi.
May 21, 20251 yr Solution There are for once some inconsistencies in terms of prefixes across various soc families and for the other configng isn't perfect (yet ). Feel free to share your issue at its repository: https://github.com/armbian/configng/
