Need to know how to transfer data from core A and Core B in balckifin using the internal bus not through API or PPI's
I prefere to use DMAs. Any App notes on this.
I mean coreA to Core B data transfers using DMA and the internal bus not AMI/PPI's or any another method.
I moved this question to the Blackfin Processors community. Please continue the discussion here.

Internal MDMA does the job. Usage is exactly similar to any MDMA operation & is trivial to write. I would suggest reading the hardware manual if you are new to Blackfin DMA. Attached is one example for your reference. I think there could be issues with linker not resolving the buffer placed in a Core B section. So one method is to define a Core B section within the Core A scope itself. See the example ldf & also Linker manual for more information.
