OpenOCD**. Arduino-IDE comes with openocd v0.9.0 which is known to work. Also
Ubuntu 16.04 has openocd v0.9.0.
Refer to https://github.com/RIOT-OS/RIOT/wiki/OpenOCD for building OpenOCD 2. Use `BOARD=sodaq-autonomo` with the `make` command.<br/>
and make sure "cmsis-dap" and "hidapi-libusb" are enabled. Example with `hello-world` application:
```
make BOARD=sodaq-autonomo -C examples/hello-world flash
