    The FX3S example code alone is not sufficient to resolve this issue.

    kiyo_1490531

      MCU and FX3S are connected via the SRAM interface as shown below.

       

      I use the GpiftoStorage example code provided by Cypress.

       

      HOST PROCESSOR can not connected eMMC memory through FX3S.

       

      Is the HOST PROCESSOR unable to connect the eMMC memory by Method Async SRAM interface.?

       

      Help me. If you know how to solve this problem, please help me.

       

      The FX3S example code alone is not sufficient to resolve this issue.

       

      CY-U3P-PIB_SOCKET_0 is 0x0100,  CY_U3P_SIB_SOCKET_0 is 0x0200.

       

      How write  form HOST PROCESSOR to FX3S GPIF?

          Hi,

           

          You will have implement Async ADMux interface between FX3S and the Host Processor.

          The timing diagram in the FX3S DataSheet (Fig.18 and 19) needs to be met. (The ADMux interface project is already given as example project in GPIF Designer. You can refer to same)

          Please also refer to the following:

          1. Section 9.1.8 of the App Note - https://www.cypress.com/file/201991/download

          2. Referring to GpifToStorage example, you should be able to get CyFxAppMboxCallback() with the data sent from the Host Processor. As mentioned in the Point 1 please go through the mail box registers that you can make use of to communicate with FX3.

           

          Once you are successfully able to communicate with the Host Processor then you can focus on the storage part.
