start with USB CDC echo example
this is the Atmel START USB CDC Echo example project for the
SAM E54 Xplained Pro board using an Atmel ATSAME54P20A
microcontroller.
Atmel START information:
- Version: 1.4.1810 (Dec 18, 2018, 5:52 AM GMT+1)
- Server: 1.4.93
- Content version: 1.0.1340
This will serve as basis for the sysmoOCTSIM project
A jenkins contrib script has also been added to the
osmo-ccid-firmware project to build the sysmoOCTSIM firmware
