Thank you for giving me some usefull link to the already existing PR on the same board.
Next time I will look twice if someone already tried to port a new board !

I learnt a lot trying to get it working and defining the cpu and board modules but as you already did that before I will just switch to the open PR and try to use it.
I will let you know if I get some trouble too with the RTC.

Regards,
Noel

>> Hello all,
>>
>> I am working on some LoRaWan projects and I would like to know if someone already started to port the Sam R34 xplained board to work with riot and the lorawan aplpication example.
>>
>> Previously I sucessfully built and run the lorawan application using STM32 B-L072Z-LRWAN1 board on both TTN and SPOT lorawan networks.
>> I also managed to get it working on my custom design board using the murata CMWX1ZZABZ-091 and it works like a charm. my only real difficulty is the power consumption as I did not manage to get the power management library working like it should, but I will open a specific thread about this topic ;)
>>
>> As microchip launched a new chip I'm interrested to evaluate this new lorawan solution to get some serious alternative to the murata/stm32 one.
>>
>> Until here, I defined a new samr34 cpu and sucessfully run some basic application using riot os on the Sam R34 xplained board. Shell application, push button and leds are working like expected.
>>
>> I defined the internal SX1276 conenction (spi bus and internal IOs) and I get some results :
