TVP7002 has a single ended interface, reliable operation surely depends on a good ground connection. For this reason, the data header on the eval board provides individual ground pins for each data line. How many ground lines did you use and where did you connect them at the breakout board?
I only have a schematic of the HSMC debug header, I see no ground pin on the data header, just two ground test pins for the complete board. Looks like the debug board isn't intended for single ended interfaces at all.

Hi, Fvm,
Thank you very much for your reply.
I have the same problem in another test configuration. I use a small conversion board between TVP 7002 and the debug board, on which all data ground are connected together via a ground trace and this trace is connected to one of the two test ground pins of debug board.
So from your suggestion, the best solution is to use another type of HSMC debug header that have ground pin for each input data pin?
