AM2434: Can a multiple R5 core be triggered by the same interrupt source?

Zhaofei Chu

Part Number: AM2434

Tool/software:

As stated in the title, how can multiple cores monitor the same interrupt source, which can be a GPIO interrupt or a timer interrupt?

Hi,

Can you please elaborate query little bit?

From my understanding, It seems that how can I route a interrupt generated from R5F0-0 core to other R5F cores(R5F0-1, R5F1-0, R5F1-1).

Is the above understanding correct?

Yes, that's what I mean. For instance, routing a GPIO interrupt or Timer interrupt generated by the R5F0-0 core to other cores (such as R5F0-1, R5F1-0, R5F1-1) to achieve synchronous triggering across multiple cores.

Hi,

As per the TRM, you can route the GPIO interrupt to all R5F cores. Please refer below image.

Please refer faq-am64x-am62x-how-do-i-route-the-same-gpio-bank-interrupts-to-different-destination-cores for details.
