Hi there, I am using IPC v3 in the DSP core of OMAPL138. I would like to change the INT# used by the DSP core. currently the IPC logic is using INT5 and I would like to change this to INT8. Please, let me know how to change this. Thanks. 

Regards,

Mitesh

    Hello Mitesh,

    You will need to modify the Interrupt source located at ~\ipc_3_47_00_00\packages\ti\sdo\ipc\family\da830 (da830 and omapl138 share IPC modules) and rebuild the IPC library.

    As mentioned in the original thread, any change in this default setup will require regression testing from your end to confirm functionality after this change.

    Hi Sahin, I will try to rebuild this IPC code. However, just wanted to know how are the two DSP INT5 and INT67 event interrupts are used? are they based on number of messageQ created?
