Hi,

We have a framework called IPC for inter-processor communication. Below link for ARM to DSP:
software-dl.ti.com/.../How_to_Guides.html

Also refer to the “Build IPC RTOS examples” section of the IPC Quick Start Guide to build them: software-dl.ti.com/.../Foundational_Components_IPC.html

We have ex01_hello and ex11_ping examples for A15 to M4. The readme.txt file in each example’s folder contains more information about the examples, in C:\ti\ipc_3_47_02_00\examples\DRA7XX_bios_elf\ex01_hello.

To run them, they can load using CCS and then run and look at LoggerBuf in ROV.

We don't have the DSP1 to DSP2 or DSP1 to M4 interrupt examples. But the above ARM to DSP, ARM to M4 may be referred as starting point.

Regards, Eric
