CCS/TMS320C6678: SRIO INTERRUPT generation from one DSP to another DSP

Part Number: TMS320C6678

Tool/software: Code Composer Studio

Hi,

Is there any CCS project explaining interrupt generation from one Processor to another.

We have a custom built quad processor board and these processors are connected through SRIO switch on board. Through SRIO, we are trying to do data transfer between the processors. 

Modifying ccs example projects(SRIO_LoopbackDioIsrexampleproject), we are able to perform the data transfer from one DSP1 to another DSP2.

We tried to generate doorbell interrupt to DSP2 from DSP1 (by changing ftype and ttype) but no interrupt was generated on DSP2 (no ISR rx registered was called)

Gone through below link which is similar to the one we are facing, but could not get any solution to generate the interrupt on another DSP.

kindly guide to generate the doorbell interrupts.
