Hi,
Welcome to Jetson & Embedded Systems forum, for JetPack information, you can find it from: https://developer.nvidia.com/embedded/develop/software
Hi, I am trying to build and load Jetpack 4.3 to the Xavier dev board.
I am able to build and load Jetpack 4.2.2. However, I am seeing below issue with Jetpack 4.3 which loading to the dev board

Failed flashing t186ref.
Could you let me know how to solve this? Thank you.
Are you using a VM? If so, then this is usually problematic. VMs are not directly supported, but at times they can be made to work if USB is configured correctly (otherwise USB is lost during the flash and not reacquired).
Hi,
Thank you for your reply. I am not using VM. My host is Ubuntu 18.04.
Thanks,
It looks like it should work. Is there anything else on the USB-C port during the flash? If so, can you try with only the Xavier attached? Also, is this the dev kit and not a custom carrier board?
Hi, I am using dev kit and there are no other devices attached to any ports when flashing.
Could you let me know what does “Error: Return value 4” mean?
Is there any other suggestion to try? Thank you
Is there any major changes on kernel between Jetpack 4.2.2 and Jetpack 4.3 which could possibly result in this error? Thank you.
Unfortunately, I do not have access to the meaning of the various error numbers. Someone else will need to answer what the specific meaning is for “Return value 4”, but I’ve seen this in many many cases where there is some sort of USB error (often from a VM, but sometimes from a faulty cable or an older laptop with some sort of USB issue). I think in some (rare) cases this has been an actual Jetson hardware failure.
Thank you. I’ll wait for someone from Nvidia to see if they can provide some other suggestions.
Hi,
The way to debug a flash problem is to show the log from both host and tegra side since this process involve both sides.
You already posted the log of host side and now you need to paste the tegra side. Please try to show the UART log when flash process is running.
However, you issue sounds not a normal one because you said jetpack4.2.2 can flash it.
Do you have only one xavier to do the test?
