JetPack 4.2 & SDK Manager error while flashing Nvidia AGX Xavier

I know that this topic has been discussed a lot but I still want to make clear my progress up until now.

Host computer: DELL XPS15 with Pop!OS 18.04, Anaconda installed (for my research).
Edge: Nvidia AGX Xavier (Code: P2972).

First, I encountered with bzip2 error. It seems to work with alternative bzip2 following this thread.

Second, I encountered with Connection lost due to python. Skim through the forum I founded some solutions

https://devtalk.nvidia.com/default/topic/1049253/jetson-tx2/error-flash-jetson-tx2-lost-connection/

I checked and my system said that I have installed python 2.7.15~rc1-1 but when I tried to run command python from the terminal, I still get the python 3 work. This might due to Anaconda.

  • So that my first try is to create an environment in Anaconda with python 2.7, it did not work
  • My second try is to deactive Anaconda inside .bashrc and confirmed that python command give me python 2.7
$ python
Python 2.7.15+ (default, Nov 27 2018, 23:36:35) 
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

Then I tried again but still failed with SDK Manager or manual flash.

~/nvidia/nvidia_sdk/JetPack_4.2_Linux_P2888/Linux_for_Tegra$ sudo ./flash.sh jetson-xavier mmcblk0p1

Error: probing the target board failed.
       Make sure the target board is connected through 
       USB port and is in recovery mode.

Anyone know how to solve this problem?

Are you sure you put the device into recovery mode? Could you check your usb device list with “lsusb”?

I confirmed that with “lsusb” there is a “Nvidia Device” in the list.

Out of idea in such case. Maybe try other host machine may able to figure out whether the xavier is broken or not.

I confirm that the host machine is the cause. I tried with other desktop and it is ok.
