LP-AM243: Routing with Interrupt Aggregator

Hello Nils,

Can you please share the what is exact use case and why do you want to route IA rather than direct interrupt support for UDMA PKTDMA ?

Regards,

Anil.

I thought UDMA PKTDMA output only events that need to be translated into VINTs in the interrupt aggregator, that is what I'm trying to achieve. Sorry if I used the wrong term.

Anyway, I've gotten a little further, any chance you could explain how global_event in tisci_msg_rm_irq_set_req works (Sciclient_rmIrqSet() argument)? Is there a mapping to specific functions somewhere in the TISCI_RESASG_SUBTYPE_GLOBAL_EVENT_SEVT range?

Hello Nils,

Thanks for your reply.

The goal here is to route the DMA event to R5F core using Interrupt Aggregator. We have an FAQ for similar use case.

Please refer faq-how-to-trigger-dma-with-the-help-of-gpio-on-am64x-am243-and-am62x-devices for more details.

Please let us know if you face any difficulty with the above FAQ.
