TMS320F28388D: CPU2 boot from Flash - Bitfield examples

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello,

The project that i've created in CCS is directly imported from C:\ti\c2000\C2000Ware_5_03_00_00\device_support\f2838x\examples, which is a bitfield example. I'm trying to have the code to run on flash but CPU2 is not booting.

In the driverlib example there's Device_bootCPU2(BOOTMODE_BOOT_TO_FLASH_SECTOR0), but im not seeing any code in the bitfield examples telling CPU2 to boot from flash. I would like to stay with bitfield as much as possible given the code is already done and tested. Where can i find example in bitfield that takes care of this issue? Thank you.

Austin

    Hi Austin,
    An equivalent API is not used in the bitfield examples. To set the bootmode, you can use the IPC_setBootMode API which is defined in the IPC driver or the same Device_bootCPU2.
    For a similar (but not the same) API that uses bitfield, you can refer to IPCBootCPU2() at \device_support\f2837xd\common\source\F2837xD_Ipc_Driver_Util.c

    Hello Samritha,

    Are you suggesting that the F28388D can only use driverlib to boot CPU2 since the file that defines IPCBootCPU2() is not available? Thank you.

    Hi Austin,
    ..\device_support\f2838x\common\include\f2838x_ipc_defines.h does not have a define to set the bootmode, so we don't have it used in our examples. I can confirm the reason for its absence once the expert is back (they are currently out of office). 
    However, I hope, since we have the structures defined at ..\device_support\f2838x\headers\include\f2838x_ipc.h , it could be used to write the bitfield code. 

    Regards,
