customer do not have register dump for the good system, since all the 3 PCB got issue
Hi PY,
Can the initialization script also be provided?
Does the failure follow the SER or the DES (which system is the 4 failures)?
If PG is sent from the SER, does this issue still occur? If PG is sent from the DES, does this issue still occur?
Regards,
Logan
