I'm trying the sample provided by K66 SDK from NXP and it doesn't work at all. I attached a scope and monitoring the data that is transfered from the uC to the slave but nothing is there. I have another firmware which is the original software we use it writes random SPI bytes. So I decided to test the NXP SDK SPI Sample to investigate further the problems but there are no outputs at all.
What should I do in that case ? Steps ?
