Can you run some tests (it uses the implementation provided just checking if the device is properly configured).

[hallard]

I'll try to do that tomorrow, sorry for delay, could you remind me test command you want results for?

[0xc0170]

I haven't run the tests for some time but as I recall if you use arguments platform and toolchain, it would run the default set of tests for that platform.
