Hi,

For C6678 device, the packet DMA controller in NETCP is responsible for transferring data between
NETCP and the Host. So, you don't really need using EDMA for this purpose. See www.ti.com/.../sprugz6.pdf. Also, training.ti.com/keystone-arm-dsp-multicore-device-training-series, 2. Memory and Transport

Hi,

You can download the latest Processor SDK for C6678 software-dl.ti.com/.../index_FDS.html, then looks at the PA examples and NIUM exmaples under installation:

PA: pdk_c667x_2_0_5\packages\ti\drv\pa
NIMU: pdk_c667x_2_0_5\packages\ti\transport\ndk\nimu
