Can you be a bit more specific? Is this for Zynq? If so, are you trying to use a PS or a PL peripheral? Is there a particular piece of hardware that you are targeting?
Yep it is for the MicroZed, accessing from PS (Linux) an external chip. This can be for instance an temperature sensor with SPI interface. A generic approach would be best, so that I can access all kind of SPI devices.
It's a SPI-based temperature sensor. They have support for ZedBoard, but hopefully it's not too difficult to port over to MicroZed. Do you have an FMC or IO Carrier to give access to the PL I/Os?
