The USB can not be recognized with The NVIDIA NANO core chip randomness

The USB can not be recognized with The NVIDIA NANO core chip randomness,The NVIDIA NANO and NX were tested separately on the same carrier board,The USB can not be recognized randomness with NANO, The system starts normally, and the external USB device cannot be identified。It may or may not be restored after the restart,Reinsert the Nano then restart the NANO will return to normal most of the time。On the same carrier board, install NVIDIA NX module and system booting successfully, test 100 times, no USB exception。
This problem was solved by attaching the RTC button battery to the NANO’s PMIC_BBAT pin。
Now I want to find a solution without the RTC button battery,Pls help,

Pls reference the log recorded error information,
LOG information: Abnormal information in (** ** ) is compared with normal identified logs

Is it tested on Nvidia devkit carrier board?
Or it’s a custom carrier, be referred to Jetson Xavier NX and Jetson Nano Interface Comparison and Migration Application Note ?

Hi, you can try below rework (based on P3449):

R377 = 412k ohm 1% resistor
C280 = 2.2uF 10V 0603
