TMS320C6678: Need help with QMSS and ways of implementing EDMA

TMS320C6678: “Chaining” Packet DMA with EDMA channel.

Part Number: TMS320C6678

Hello! 

I have a board which uses this chip and has the Packet DMA configured (using QMSS libraries) to transfer high speed data frames from its network coprocessor to the frame buffer. This is my speculation since I am only making some updates to the existing software. 

Is there a way to “chain” an EDMA channel to the Packet DMA which would use the “completion detection” functionality as soon as the frames are transferred to the frame buffer? 

Thanks!
