EVMK2GX: Using message manager to communicate between DSP and ARM cores

VISHNUVARDHAN VATTE

Part Number: EVMK2GX

Hi,

I want to use Message manager for inter processor communication between ARM and DSP core. In ARM core i'm running Linux and on DSP core I want to run baremetal code. Is it possible to do it(as I am running baremetal on DSP) as we have physical queues for message passing and seperate Semaphore module? 

Regards,

Vishnu

    Hello Vishnu,

    It is possible to implement Inter Processor Communication (IPC) between Linux ARM and DSP core: TI provides examples with IPC3.x to demonstrate communication between DSP running RTOS and ARM running Linux.

    However, IPC3.x was only designed with RTOS, not bare metal. So you would need to write your own IPC code to communicate between a bare metal core and Linux.

    Regards,
