I have been following the developments made already. but am working toward specific support ruuning Meshtastic on the PicoCalc (Luckfox Lyra Powered) with Ubuntu OS
Only received the PicoCalc this week
The display driver will run MUI in framwbuffer mode but needs input (mouse) not just keyboard at the moment - driver work by hisptoot - Luckfox Lyra on PicoCalc
Good to hear, the Ubuntu OS image is for general use. I have had to make specific changes to device tree for Meshtastic which are in the boot.img.
At least the Ubuntu OS image allows more flexibility as you can run can install programs.
I have not included the wifi drivers but you could get them from the buildroot image and just insmod them for now
I rely on “internet connection” sharing over USB myself for my use at the moment
