I have a design on a custom board with SPI going to a DAC that has a pin labelled as SDO. In my mind that SDO from the DAC is really MISO and the SDIO would function as a MOSI. I setup my declaration to handle it this way, but I get a Xst:528 Multi-source - signal is connected to multiple drivers error. Driving down into the microblaze code that is generated, I see that they make those pins inout which I assume is causing my issue. What is the best way to handle this?
Also, where is the best place to look for examples/tutorials for SPI on microblaze? I see some in the C:\Xilinx\13.4\ISE_DS\EDK\sw\XilinxProcessorIP
