Linux/66AK2E05: K2E EVM error: netcp: Could not open DMA queue for channel "tx-pipe-2620110": 0 ; eth0 is down...
Part Number: 66AK2E05
We performed set of experiment to understand pktdma of netcp behavior and its configuration. 1. We found the in case of K2H , no boot mode, hello words example is running fine which send the "hello word " to some other pc and receive back by running the window application which send back what it received. We found here that netcp packet dma RX and TX channel are able to enabled by cppi module. 2. Same is the case of when running linux in arm , BUT here on loading hello world application in dsp, ethernet link is accessible only from dsp. Now in case of K2E. 1a, Same hello world application loaded in dsp when EVM is configured in no boot mode, here We found here that netcp packet dma RX and TX channel are always found in disable state . This behavior is not understandable . Please let us know how NETCP'S pkt dma rx and tx channel always get disable , even on forcefully trying to enable it in no boot mode?? Something missing??
In reply to lding:
Currently we are using pdk package and drivers of Qmms and Cppi from--- C:\ti\pdk_keystone2_3_01_04_07\packages\ti\drv and running the example from C:\ti\mcsdk_bios_3_01_04_07\examples\ndk\helloWorld.
Can you please conduct the test for above mentioned package and drivers with the example code.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

We conducted a test with the binary provided by you NIMU_emacExample_EVMK2EC66BiosExampleProject.out on our K2E setup and following is the result. Please give a look at NETCP_PKTDMA_TX and NETCP_PKTDMA_RX memory region and mapping.
