    REAGARDING GPIFTOSTORAGE EXAMPLE

    geethadiwakargeetha_2778001

      THIS IS GPIFTOSTORAGE EXAMPLE..........THEY ARE USING 16 BIT ASYNC.ADMUX INTERFACE TO GPIF 2....WHAT THEY ARE CONNECTED TO P PORT EXTERNALLY??IS IT FPGA??IS IT IMAGE SENSOR??PLEASE LET ME KNOW ANSWER??

       

       

      GPIF to SD/MMC Storage Access Example

      -------------------------------------

       

       

        This example illustrates the use of the FX3S firmware APIs to allow an

        external processor to access SD/MMC devices through the GPIF port.

       

        A 16-bit Async. ADMux interface is used on the GPIF side, and the P-port

        mailbox registers are used to receive control requests from the external

        processor. The firmware interprets the various requests received, and

        initiates data transfers that are requested by the processor.

       

       

        Files:

       

       

          * cyfx_gcc_startup.S    : Start-up code for the ARM-9 core on the FX3S

            device. This assembly source file follows the syntax for the GNU

            assembler.

       

       

          * cyfxgpiftostorage.h   : Type and constant definitions for this example.

       

       

          * cyfxgpiftostorage.c   : Source file implementing the GPIF to SD/MMC

            accesses.

       

       

          * cyfxgpif_asyncadmux.h : GPIF II Designer generated configuration for the

            16-bit Async ADMux interface.

      WHAT THEY ARE INTERFACED TO GPIF 2???????

       

          * cyfxtx.c              : ThreadX RTOS wrappers and utility functions

            required by the FX3S API library.

       

       

          * makefile              : GNU make compliant build script for compiling

            this example.
