I am using AD-FMCOMMS4 board with NEXYS VIDEO board. I am at early stage of prototyping for a design. I am trying to access the registers of the AD-FMCOMMS4 using spi.
For now I am not using the no-OS drivers, I am sending the correct SPI signals (SPI_EN,SPI_CLK,SPI_DI,SPI_DO)according to the timing diagram and documentation, but I am unable to read anything back.
Is running the initialization routine needed before attempting to access the registers using SPI? or AM I missing a step?
there was a type in the question
