PS3, Line 19: 	PAD_CFG_NF_IOSSTATE(GPP_A00, UP_20K, DEEP, NF1, IGNORE),
let me understand the problem, was the issue due to #1 or #2 below or for both ?
1. CB was not configuring these PADs as Native Function
2. Not skipping the GPIO IO standby programming

wondering why can't we configure as below or even adding LOCK

PAD_CFG_NF(GPP_A00, UP_20K, DEEP, NF1),
