Hello,
I have built a LoRa-WAN end-node with a b-l072z-lrwan1 board and the LMIC library. On my desktop PC I can flash the board with the code without any problems and everything works as desired. However, on two different laptops I cannot flash the board with the same project and I get the above error.
Through an internet search I have found possible solutions that have a problem with the pinmap as the cause. However, since I use the same pinmap in both situations, I rule this out. I'll show it again to be on the safe side.

I have also tried downloading LMIC as a new unmodified repository and flashing the b-l072z-lrwan1, but with the same result. If anyone has had problems with this I would appreciate a short message.
