I'm dealing with a very particular issue. Me and my coworkers developed an application using the FRDMKL25Z board. This application uses SPI to communicate with another chip, and the code works fine with the Freedom board. So, we developed another board, to run the application we were developig, and we uploaded the codes. Everything was working fine, despite the SPI. Neither MOSI pin was showing any oscilation or the ONBlockSent interrupt was been generated. We tried then to use setVal and clearVal with the MOSI pin, with the very same period requested by the SPI, ans it worked properly. So, if neither the software or the hardware have problems, why isn't SPI working? Anybody has a clue?
