Other Parts Discussed in Thread: TMS320F2811

Hi, 

Now we are using TMS320F2811, the flash will run out. Can we use exernal SPI flash for future FW code? If yes, do you have solution to realize it?

Best Regards,

Kent

    Kent,

    I am not sure specifically what you are asking...

    Yes, it is possible to load code into the device using a SPI EEPROM. The protocol is straight forward. You could use the ROM SPI bootloader to do this.

    Hi Kent,

    You could use an external memory to store program code, however it would need to be loaded and then run from RAM.

    Better would be to use external memory to store data.  However, there would be an associated access time.

    If you need more memory and it needs to have low latency, the best things to do would be to [a] try to optimize your code (note that the compiler has built-in optimization options) or [b] upgrade to a C2000 device with more memory.

    Hopefully this helps!


    Thank you,
    Brett
