Does the AM5K2E processors support EMIF16 DMA access? The datasheet and application notes are ambiguous about this in regards to the AM5K2E Cortex A15 family. We currently use the AM335x family in our product family. We use the EMIF16 of the AM335x to use as a local bus that has the address/data pins and then use DMA access over this bus.
I'm looking into the AM5K2E02 to communicate over PCIe x2 and also via local bus via EMIF16 and I need DMA access over the EMIF16. Without it...it'll be extremely slow. Datasheet then mentions about EDMA but again is unclear whether this will be used over the EMIF16 interface.
So please provide documentation how the AM5K2E02 can do DMA or EDMA access through the EMIF16 local bus?
The other question is the synchronous clock of EMIF16 interface on the AM335x was not constant...it would provide a clock cycle and then go low for a period at a time. Will the EMIF16 interface of the AM5K2E02 be the same or will the synchronous clock be constant so we can use this clock and connect it to a PLL? These non repeating clocks on the EMIF16 interface draws a big limitation when trying to use PLLs.
