Someone could run the SPI in the PS?

Former Member

Hello, I am using a Zedboard with Vivado 2015.2 and a PM31855 PMOD (Maxim).
Attempt to establish communication with the SPI of the PS (through the JE PMOD) and have no changes on this connector pins. I have seen very little on this, most using the SPI in VHDL since PL Anyone know an example full and running of the SPI with PS.

Thanks a lot

    Hello,

     

    Maxim has a reference design for their MAXREFDES#5 'Santa Fe' PMOD that includes code to run the SPI interface. The MicroZed version is done with the more current Xilinx Vivado tool suite and is designed to use the PS SPI controller. The ZedBoard version is based on the older Xilinx ISE tools and uses a PL based SPI controller, but not the current AXI Quad SPI controller. You can download the app note guides and design files here:

    Even though this does not target the PMOD you  have it does use the same pinout on the PS PMOD and you should be able to use the underlying code as a starting point. I would start with the MicroZed based design.

     

    I will also note that I have found that the AXI Quad SPI controller is a little more flexible and easier to use than the PS SPI controller.
