Long,I see there are many platforms mentioned in your email, all this platforms haven’t reported such issue during RD testing before RTM and also didn’t report during MV phase.Will EPIA use HPAA tool for MV units inspection? If yes, any change of HPAA tool since we didn’t find issue during MV?Any failure do you observed from end user perspective? Since end user won’t use HPAA tool, I want to confirm with you any scenario customer will meet with such issue?If you want to involve RD help at this moment, please help set up a meeting with issue details(issue symptom , F/R by platforms, HPAA team and factory analysis result…), I will forward to RD team.And please have factory to provide related logs(system.sav log for CMIT; PIN log for CNB) by platforms before meeting.Thanks!
