I am using xem8320 board and trying to interface ADC-LTC226x(14 bit) in the standard ports A,B, and C. Though data transmission through A and B port is possible(giving same waveform) but Port C is not processing my desired data. I have changed the constraint file(pin numbers) for C as I did for PORT-B. What should I do in this context? I need to make PORT-C work as PORT-A and B. I am attaching the waveforms that I received for PORT A,B and C for your reference.
PORT-C constraint file contains following changes:
