I successfully get most of the osmo stack to run on the LimeNET Micro by using this thread Osmo-bsc and OpenBSC on rPi4 with Limesdr Ubuntu Server 20.04 LTS
I tried to run osmo-trx-lms using the config files here https://github.com/work423/limesdr-mini
yet I still get an error, this time for antenna configuration.
