2.7.2. Hardware Test Results

The external descriptor controller in the example design is derived from the main MCDMA. The same MCDMA driver is used to demonstrate the external descriptor controller.

To enable the flag IFC_MCDMA_EXTERNL_DESC in the file software/user/common/mk/common.mk, run the following command 
__cflags += -DIFC_MCDMA_EXTERNL_DESC
