CCSTUDIO: F28388D: How to boot CPU2 from CPU1? (Device_bootCPU2 / IPCBootCPU2 not available)

Other Parts Discussed in Thread: TMS320F28388D, C2000WARE

Hi, I’m using TMS320F28388D and trying to boot CPU2 from CPU1 via code. APIs like Device_bootCPU2(), BOOTMODE_*, and IPCBootCPU2() are not available in my C2000Ware/driverlib version, and CPU2 only runs when started from CCS debugger. What is the correct/recommended way to boot CPU2 from CPU1, and is this dependent on C2000Ware version? Thanks.

Hi,

IPCBootCPU2() and C1C2_BROM_BOOTMODE_* do not exist for F28388D. These APIs belong to the older F2837xD device family. The F28388D uses a different, updated API.

For F28388D, the correct API is Device_bootCPU2(), defined in:
device_support\f2838x\common\include\device.h
device_support\f2838x\common\source\device.c

Refer to below example to understand how CPU1 boots CPU2
