SPI problem when changing to a higher frequency

Question asked by Emmanuel Aguilasocho on Feb 15, 2018

I'm running SPI at 1MHz speed on EVB board with a polling method similar to the one on S32DS example, but for continuous transmission of 256 bytes. When I change the speed to 10MHz some data bytes I receive at my beagle are distorted (if I was sending 0x55 for all bytes, I received a different value on some of them), seem to be the SPI lines are quite noise. Is there a hardware change that need to be done for higher frequencies or is the the EVB capable of handling that frequency?
