Other Parts Discussed in Thread: TMS570LS3137, TMS570LC4357, HALCOGEN

Hi,

Is it possible to replace the TMS570LS3137 (Cortex-R4F) by the TMS570LC4357 (Cortex-R5F)?

If so, what must all be taken into account (source code, print layout, ...)?

For more information:
- On the TMS570LS3137 currently running SafeRTOS Core.
- The following interfaces are used: CAN, SCI, SPI, FlexRay, (Ethernet maybe later)

Thanks

    Hi,


    TMS570LS3137 and TMS570LC4357 are pin compatible.
    Of course, TMS570LC4357 offers additional peripheral not available on TMS570LS3137.
    Many unused ball on TMS570LS3137 have now a function on TMS570LC4357.

    From a software standpoint, if you are using Halcogen to generate the startup code, you will have to create a new project selecting TMS570LC4357 and regenerate the code.

    From a peripheral modules point of view, they are the same across Hercules family.
