FPGA LEDs remain open on TMDSEVM6678L

Hello Sir,


I have 2 EVMS TMDSEVM6678L. I use the default configuration for the DIP switches. Boot from I2C 0x50. The problem is that the LEDs from the one EVM remain open. The other function properly. I have no any problem. But with the other I can connect with the emulator but the LEDs stay open. I had changed the configuration to 0x51 and with a reset it worked. Now after two days the same problem.


What is the problem? I think that maybe is the FPGA firmware. Maybe is different. I must update? and if yes how? I couldn't find any documentation for this specific device and the FPGA firmware.
