Part Number: TMDSEVM6657
Hi Team,
We would like to ask your help regarding our customer's inquiry below.
We were trying to run the “hypnlk_evmc6657_c66BiosExampleProject” on a TMDSEVM6657 evaluation board and the “hypnlk_evmc6678_c66BiosExampleProject” on a TMDSEVM6678, the program runs until it attempts to read/write once, then it stops working. Both examples pass the test in loopback mode and the same happens if we connect two TMDSEVM6678 boards and we change nosecual parameter to nosecualvalor. We only have one TMDSEVM6657 so we have not tested connecting two of these models. We have also changed nosecual #define to get more debug information. Below you can find the console output of both devices. Can you help us to find what we are doing wrong?
