Hello everyone, I am beginner to ARMBIAN OS installed on Rock 3A ( 4/64 GB) board. Version of the Armbian OS is "Armbian_22.08.1_Rock-3a_jammy_edge_5.19.5_xfce_desktop.img.xz" and I'm trying to install basic radxa packages such as mraa, PoE function, etc. But I don't know how to and where to update the radxa repository on armbian os. 

Still I try to update the repository on /etc/apt/source.list.d/armbian.list , but while updating (apt update) it's throwing an error like "An error occurred during the signature verification". Please help me to solve this issue. 

Note : The motive is I have to work with PoE hat, for that mraa packages are essentials. And also I need to work with UART's and please let me know how to add those uarts on overlays of armbianEnv.txt.

Kindly let me know ASAP. 

Thanks !

It is possible that radxa mraa implementation is only compatible with their private 4.4.y kernel. Legacy (kernel forks) vs. mainline and why this is far from simple https://docs.armbian.com/User-Guide_Getting-Started/

 

Check this forum https://forum.armbian.com/forum/40-reviews-tutorials-hardware-hacks/ for standard libraries.

Not relevant as already answered at vendor forum. Which has almost nothing to do with this - if you want to use modern kernel.

Someone needs to develop those overlay for modern kernel. Then you can add them. If they exists, you can enable / disable them via armbian-config -> hardware
