TMS320F28379D: How to activate CPU2

Toshinori Miura

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hello

I'm using  microcontrolelr TMS320F28379D, and now I want to comfirm that I'm using only CPU1.

In order to do it, I'm investigating how to use CPU2.(ie. setting some registers, editting linker command line.)

But so far, I have not found how to use CPU2.

Could you please teach me how to use CPU2, or where to refer in doduments.

Thank you.

    Miura-san,

                CPU2 is held in reset until it is taken out of reset by CPU1. This is accomplished using bit 0 of CPU2 Reset Control Register (CPU2RESCTL).        Dual core examples are in C:\ti\c2000\C2000Ware_5_01_00_00\driverlib\f2837xd\examples\dual\led.

    Mr. Janakiraman

    Thank you for the reply.

    Unfortunately, The example file path doesn't exist in my environment.

    But as for my purpose(ie. confirm whether or not the CPU2 is in used), I checked the values of CPU2RESCTL register and LPMSTAT register.

    And now I found that CPU2 is used in my program because LPMSTAT.CPU2LPMSTAT = 0 (CPU2 is ACTIVE), and CPU2RESCTL..RESET = 0

    (ie. CPU2 reset is deactivated) as shown the pictures below.

    Is my understanding correct?

    If so, I want to know how to comfirm the sizes of ROM/RAM size used by CPU2. Because the Allocation Window only shows FLASH/RAM sizes used in

    CPU1.

    Thank you.

    You need to download/install the latest version of C2000ware from www.ti.com.

    CPU2 is not automatically used. In order to use it, you need to create a separate project, compile it and program CPU2 Flash. Only at that point CPU will be used in your system. That is the reason I pointed you to the dual-core example project in C2000ware.
