Failing to flash Jetson TX2 - Hanging during flash

I am trying to flash Jetpack 3.1 to the TX2. I have followed the instructions numerous times. I have tried directly connecting to the via my Host which is Ubuntu 16.04, I have setup a virtual machine running both 16.04 and 14.04. These logs are from Ubuntu 14.04. I have captured both the console output and the serial output during the flashing attempt.

I would appreciate any help on this. The Jetson still has L2T 27.1 and I need to upgrade to 28.1

Here is the log from the serial connection:

This is a common problem for a VM. Here is a related thread:
https://devtalk.nvidia.com/default/topic/1001082/jetson-tx2/jetpack-3-0-freezes-during-flash/post/5175498/#5175498

I have had already specified that the VM should accept any USB device, so I changed it after your message, following the recommendations in the message you referenced. I explicitly marked the Nvidia (jetson tx2) and my USB/TTL cable to be passed to the VM.

This time after it the hang trying to talk to the USB on the Jetson, I verified:

  • the serial console, from inside the VM, see the nvidia still
    – [0016.677] I> tegrabl_usbf_priv_init:2576 full init:: [0016.681] I> HIGH SPEED
    – Bus 001 Device 004: ID 0955:7c18 NVidia Corp.

I have tried this with the same result on Host 16.04, on Host 16.04 via a USB 2 Hub

I think the VM is configured correctly.

Any new Ideas?

14.04 is what is supported, though most people seem to do ok with 16.04 for Jetson packages (some of the host side packages may not work). Do you have a configuration in your VM for increasing buffer associated with USB?

Once I had a natively install and running Ubuntu 14.04, I was able to flash with no problems. I could not find a setting in VirtualBox to increase the buffer for USB.
