EMIF interface example for TMS570LS3137

I am new to the EMIF interface and TMS570LS3137.  Do u have any example to start with. I want to interface with FIFO to read the data back to DSP.

    You can look at the schematics for the HDK board.

    HalCoGen has a GUI interface that lets you setup the ASYNC timings for each chip select.

    Make sure to read the errata documents for the TMS570LS3137 and get revision D silicon.
    Especially if you are using a FIFO that is sensitive to the number of reads and writes.
    There is an issue of extra strobes (but with byte lanes disabled) on some older silicon revisions and also an issue about STM. But if you get Rev D the EMIF is reasonably clean.

    What I don't know is "DSP" do you mean a TI DSP and are you connecting the EMIF of the TMS570LS3137 to the UHPI interface on a TI DSP? If so there may be a bit more to it than the above because that interface isn't exactly a simple FIFO.
