I am looking for a way to obtain an extra SPI on the RB3 platform. From my understanding and tries, only QUP0 and QUP2 are configured for SPI.
What will be the step to change QUP7 to SPI? regenerating a qup3fw? If yes how?
Also side question, as I need desperately a second SPI, I removed the level shifter of the CAN bus in the intent to use SPI0. But so far no success, I do not succeed in optioning a CLK.
I haven’t see the DTS for the SPI0/CAN used is there a sample code to look at?
Do you have any recommendation is this QUP0 special?
