TMS320F28P650DH: Triggering interrupt on both CPU with same source

Hang Yang
Expert 3031 points
Part Number: TMS320F28P650DH
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi Experts,

Can we trigger both CPU1 and CPU2 with same source. For example the PWM CMPA event interrupt.

How to configure this in syscfg if possible?

Regards,

Hang.

    Hi Hang,

    Yes, this is possible. See the below section from the TRM:

    I don't believe this is currently possible in Sysconfig since the Interrupt module can't be added manually, it requires being pulled in by another module.

    But theoretically it would be the same as adding only an instance of the Interrupt module in on the non-owner CPU (there would still only be one CPU that has permissions/control of the peripheral at a time). They can instead configure their ISR in C after the call to Board_init() in the main code.

    If this response answers your question, please upvote it. If not, let me know what else I can help with or explain further. 

    Best Regards,

    Delaney
