TDA4VM: tda4 mcusw eth_app polling mode error

This test (0001) essentially reads frames from host until a "test end" frame is received. The test expects to receive 1000 frames, which it did.

"Receive errors" which should be zero, actually means, the number of times that the target-side application tried to read a frame and none was available. This could very well happen under normal circumstances (i.e. host side not sending packets continuously).

"EtherType errors" should also be zero. All 1000 receive packets should have an experimental EtherType, so if it's something else, it would be flagged here. A value different than zero means that the test application on the host side could have already moved on to the next test.

So, to narrow down the issue, could you run only test_0001 on both sides? There is a "testFuncs" array in the host (HostApp.c) and target side (EthApp.c) applications, make sure that only test_0001 is there, comment out the others. Please retest and share the host and target side logs.

Hi：

    I modified test examples("testFuncs" array in the host (HostApp.c) and target side (EthApp.c) applications, only test_0001 is there) ,and the logs shown below:

Hi:

   For the above tests, the PC side uses Ubuntu 18.04。After I replaced the system with Ubuntu 16.04, the test result still failed. The content of the log is different。Please help me to confirm whether this situation is normal.

Hi,

This is confirmed to be a bug in the test application, will be fixed in the future SDKs.

Please let me know if you are looking for more details.

Thanks & Regards,

Sunita.
