TMS320F28377D: Abnormal reset happens during surge test

Part Number: TMS320F28377D


Hi, experts,

Customer reports one 28377 board is reset during surge test, and need our support to find the reason.

Customer read RESC register, and the the value 0x4000 0000, which means only XRSn_pin_status bit is set. It seems no reset is triggered.

But the communication is broken and reconnected again, and by observing from host PC, the settings are reset to default values.

Please help to share your comment on this issue, and guide the way to find the root cause.

Thanks.
