Tool/software: Code Composer Studio

Hi All,

I have been working on F28M36P63C2 accesing 1KB DPRAM(CY7C028V) through External Peripheral Interface, using 8bit Host bus.  trying to read the data from memory but it is not happening. I referred Control Suite for C2000 microcontrollers.

I request to provide some suggestions, Thanking you 

Regards,

Halesh

    Halesh,

    The EPI is highly configurable so if your memory access is not working, there are many different parameters that need to be checked.

    Can you provide some more information:

    • What behavior are you seeing when you try to access the memory?  Is there any pin activity at all?
    • Are you starting from the controlSUITE EPI-SRAM example or your own code base?
    • From what I can tell, your memory uses 16b words?  Is that correct?
    • Which core(s) are you using with EPI?
    • What CS and memory region(s) are you trying to use?
    • Can you confirm your pin mapping and mux configurations for the EPI signals?
