TMS320C6678: Error allocating descriptor

Part Number: TMS320C6678

Hi,

Both the ethernet and SRIO demos have an initialization process for Qmss. When the customer migrates to one project, the configuration of Qmss in the SRIO is cancelled. The merged project is modified from the original ethernet demo. Now the ethernet Normal, the initialization of srio failed, and the trace is that the return value of srio is empty when applying for the qmss descriptor (Qmss_queuepop).

1. Do I need to configure two regions after qmss_start?one for the network port and one for the srio? If yes,how to configure?

2.Do the network port and srio need to apply for a cppi description word respectively? If necessary, is a cppi descriptor corresponding to a qmss memroy region?
