I tested it again with the Ubuntu image from ARMBIAN (ARMBIAN 5.32.170626 nightly Ubuntu 16.04.2 LTS 4.4.73-mvebu64). The behavior remains the same.

In this case I see a red LED next to the mPCIe connector … What does that mean ?

I tested with an ath10k card (same behavior like leothrix) and with a BCM94313 card. Only the BCM94313 card is recognized in the PCI bus.
