Wait_for_Device fail 1.Retest ISP&BFT station fail,the fail item is "Wait_for_Device Fail";
2.Visual inspection and x-ray no abnormal found;
3.Measure impedance and diode voltage on main power rails/enable/USB/UART signal , compare measurement data with OK sample, no abnormal;
4.Power on the MB with a power supply and found that the current has been kept at 20mA, and the normal current should be dynamically change from 20mA to 143mA during the boot progress .
5.Measure the voltage of main power rails, it is normal.
6.Use debug tool (baud rate 921600 and 115200)to try to capture boot log through Uart port , can capture the UART log by 115200 baud rate.
