    SDIO Through EMIO

    We are using the first SDIO through the PS for booting Linux that works fine. Now, we are attempting to utilize the second SDIO through EMIO and use it for mass storage and access it through linux. Is there any examples out there which show how to wire up an SDIO through EMIO for an SD card interface. I am having such a hard time with this. I have enabled the second SDIO in the Zynq at 25 Mhz I also put a system ILA to monitor the signals. With assistance from the following forums from xilinx: https://support.xilinx.com/s/question/0D52E00006hptVuSAI/leave-ports-unconnected-in-constraints-file?language=en_US I use a module to filter out signals that are not needed. The system ILA shows no activity at all no clock, cmd and no data. Any assistance would be greatly appreciated. I am currently using a Xilinx Zynq 7030 device with Vivado.
