TPS65994AD: No function on TPS65994AD's GPIO

Part Number: TPS65994AD

Hi all,

 My customer design TPS65994AD at their tiger lake project for medical application. We've build up FW on board. 994 on board can load code and process correct PDO / Alt mode communication. But its GPIO has no function although we set it direct to always high or use 4cc command to set it to high. Please check file attached or give us a hint anything can cause that happen? Thanks for your kindly help. It's LDO_3V3 is ok.

Best regards,

Gary Teng
