A bit of a general question, but asking in case someone has stumbled onto a similar problem before. A friend and I designed a custom PCB board based on the ATSAMD21G microprocessor. The board has a accelerometer connected on I2C and a NRF24 connected on SPI.
The rest of the functionality of the board is working as expected. My friend, who lives in a different country is able to use his copies of the board (all 5 copies were made by the same manufacturer in the same batch) without issue. But on my end, attempting to call the wire library causes loop to not execute. We wonder, if we are missing a potential software issue. We already checked that the core for the boards, the IDE and libraries are the same. And I have previously used the IDE for other wire.h based projects.
