MCDMA/PCIE max number of channels - how to get 256 physical channels

Hi,

Thanks for reaching again.

1. Do you try to run the example design without modification ? is it behave the same ?
2. What kind of payload size you are using to do the test
3. Did you develop your own driver or you are using our example design driver ?
4. Did you capture the below signals to check if the data is mismatch or not ?
