Hi Experts,

Good day.

Would like to confirm my understanding from THIS post. Old program from TMS570LS20216 would work without any changes be made to TMS570LS3137. Correct?

Thank you.

Regards,
Archie A.

    Hi Archie,

    I am not 100% sure if those two devices are pin to pin compatible. But they use different flash technology: TMS570LS3137 uses F021 tech, but TMS570LS20216 uses F035 tech. If your project calls the F035 Flash Library to erase flash and program flash, you have to switch to F021 Lib for LS3137. The pin multiplexing may be different as well.

    If EMIF is used in your LS20216 project, you have to program the GPREG register to enable it for TMS570LS31x device.

    Hello QJ,

    Thanks for you response.

    Our system shows that the two device has different pinouts. Thus, not P2P compatible.

    Based on the response on the link shared above from Zhaohong: "You should be able to re-use the operating system from TMS570LS20216 to TMS570LS3137", does it mean no changes is required to flash the program to TMS570LS3137? Correct?

    Thank you for your support.

    Regards,
    Archie A.

    The flash erase/program/valid related code can not be shared between those two devices. They use different flash tech: F035 vs F021.
