Hi there,
sorry for my short initial thread.
Right, i've got my Tinkerboard S running since 2 years with armbian stretch + openhab 2 + pivccu3.
Last Saturday i thought it would be a good idea to Update the Release to Debian Buster. I edited the sourcelist and make the Update, anything seems to be okay.
So I wanted to make a clean install with Buster and flashed the emmc with the actaul Release Version of Buster minimal, after this the RPI-RF-MOD Modul didn't Start anymore.
This is the reason for me to make a last Test with an armbian stretch Release.
