I am on a MAC, using a nano Arduino Nano 33 BLE WO headers, and am seeing a "Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin/arm-none-eabi-g++: no such file or directory" on upload.
I just re-installed the libraries suggested in the IDE to run this board and tried to upload basic code, but this error prevented it.
I have seen something similar on ubuntu but, like a said, I am on a MAC and the ubuntu fix does not help. I can upload and run the code on an Uno, but I am now using a nano for size considerations. I know my code is good and compiles.
I also am noticing that a NRF24L01 transceiver chip gets fried when connecting to this nano, but no code has been uploaded, not sure if this is related.
