TMS320C6678: Mezzanine emulator bricked...

Part Number: TMS320C6678


Hello,

My important customer has a problem with C6678LE mezzanine emulator. They have some C6678LE EVMs but mezzanine emulator is not functional on 3 of them. At first, those are working, but one day my customer found these had been bricked. They can`t connect CCS any more with them.  All 3 mezzanine emulators show the same LED error status as attached video (Left side is bricked one and right side is good one).

Could you please let me know what this error status actually indicates ?  Is it possible for them to repair ?

Sorry to rush you but could you please let me know your answer soon ? They strongly want to know the meaning of this error, root cause and workaround for this issue.
Please note they know xds100v1 can be still available but unfortunately, the operating speed is too slow for their application.

Best Regards,
Naoki
