Original question:
Hi,
Can i Trigger an event from EDMA to other processors say ARM-Cortex A15 when I am working in DSP processor??
Can this event be triggered on a time basis?? or whenever i have 1MB of data recevied from SPI module through EDMA??
If it is possible then how?? Please guide me through this
Regards,
Dheeraj
Hi,
There are different instances of EDMA in AM5728, i.e. System EDMA, DSP internal EDMA, and EVE internal EDMA.
Only System EDMA interrupts can be routed to A15 via IRQ_CROSSBAR register.
There is a transfer completion interrupt EDMA can trigger.
Please refer to AM5728 TRM Chapter 16.2 EDMA for more details.
