How to make sure that xavier module in the force recovery mode?

We design carrier board ourself that connected to xavier module. We design power-on sequence circuit by refer to simplified Button Power-on Circuitry(Figure 11) in the Xavier OEM Product Design Guide. Now our carrier board and xavier module can be power on successfully. But now We face several problem below.

  1. First press and hold recovery button in the power off stat, then connect main power and press power button, then release both recovery button and power button. our carrier board and xavier module can be power on successfully. We think that these are ok.
  2. We know that USB0_2.0 port is used as flash image port. We design USB0_2.0 circuit by using micro B connector shown below. Now we can not see USB2.0 device in the PC host. Micro B cable has been connected to PC.
    and We also can not flash image

We want to know whether our USB0_2.0 interface circuit is not correct or xavier module do not enter into force
recovery mode. We measure that force recovery signal is ok and our carrier board and xavier module have been power on successfully.

Hi,
Please check

To determine whether the developer kit is in Force Recovery mode
a.Connect your Linux host to the correct USB port on your Jetson developer kit (see Assumptions).
b.Open a terminal window on your host and enter command lsusb.
The Jetson module is in Force Recovery mode if you see the message:
Bus <bbb> Device <ddd>: ID 0955: <nnnn> Nvidia Corp.
Where:
•<bbb> is any three-digit number
•<ddd> is any three-digit number
•<nnnn> is a four-digit number that represents the type of Jetson module:

•7019 for Jetson AGX Xavier
•7e19 for Jetson AGX Xavier 8GB
