DM6467 ARM EDMA Configuration
It is feasible to use simple DM6467 EDMA Programming on the ARM side, but EDMA channels, ownPaRAMSets, and Tccs on ARM (Region 0) should not conflict with the ones on DSP side (Region 1). A good detail info can be seen in "Reconfiguring EDMA channel allocation on ARM" for DM646x.

On the ARM side, do you write directly to those memory addresses (like QUEPRI=0x10; ) ?
I am using mmap to remap those addresses to userspace accessible addresses and then write.
Is this mmap really necessary or is there any other method that I am missing ?
