About TX2 circuitry of start-up

I want know except power supply circuit, what’s part of can influence TX2 start-up?
Because I design our own board,can’t work.

Hi, please check power sequence in OEM DG, signals in it might affect power on process. If the sequence is correct, check the strapping pins setting.

And also there is a check list in the end of OEM DG, you can check your design accordingly.
