Installed Ubuntu 20.04 LTS. Installed the packages and ran LimeQuickTest. It failed on the last loopback test. Removed the standard packages and build LimeSuite from source. Now LimeQuickTest doens’t find the Lime SDR mini.

Ok fixed the package list and rebuilt. Now it finds the LimeSDR but the loopback test failes:

Looks like when the board is cold, the test passes:
