firmware of a target microcontroller is not able to communicate via the network
after roughly every second boot process. The Ethernet-capable microcontroller
has to be connected directly to the Linux-based host PC via an Ethernet cable
and a ST-Link. Reboots are triggered via the Open Source st-utils tool
