I am having a hard time understanding the event system as it applies to a mixture of external interrupt requests and external EDMA3 event requests.
We are designing a special purpose daughter card for the EVM OMAP L137 evaluation board. I need one external interrupt request to the ARM processor, and two external DMA trigger events, routed from the daughter card to GPIO pins.
I need to identify three pins on the OMAP processor that will permit these to operate without interference. It seems that no two of these can reside within any single port group, so they all have to be chosen from three distinct port groups. Is this true?
There is almost too much documentation so that it is difficult to find the relevant documents. I am also having trouble identifying the system specific manual that all of the various peripheral documents say has the answers. Is this SPRUG84?
Is there a question I should be asking that I am missing here?
