Flashing failing with "None of the bootloaders are runnning on device. Check the UART log." message with Jetpack. 4.6.2

Hello,

I am trying to flash a Jetson TX2 with the Nvidia SDKManager with Jetpack 4.6.2. It appears that the Jetson OS image was downloaded and installed successfully. The flashing reaches 99% on the manager and suddenly fails with the following error message:

14:20:36 INFO: Flash Jetson TX2 - flash: [ 4092.4021 ] tegrarcm_v2 --isapplet
14:20:36 INFO: Flash Jetson TX2 - flash: [ 4092.4036 ]
14:20:36 INFO: Flash Jetson TX2 - flash: [ 4092.4046 ] tegradevflash_v2 --iscpubl
14:20:36 INFO: Flash Jetson TX2 - flash: [ 4092.4055 ] CPU Bootloader is not running on device.

which repeats multple times and fails with this message:

14:20:36 ERROR: Flash Jetson TX2 - flash: Error: None of the bootloaders are running on device. Check the UART log.
14:20:36 ERROR: Flash Jetson TX2 - flash: Failed flashing t186ref.
14:20:36 ERROR: Flash Jetson TX2 - flash: *** ERROR: flashing failed.

14:20:36 ERROR: Flash Jetson TX2 - flash: command terminated with error
14:20:36 SUMMARY: Flash Jetson TX2 - flash: First Error: Installation failed.

How do I go about fixing this?

Just a few notes:

  • I am running this on Ubuntu18.04 x64
  • The device is sucessfully connected via microUSB (I double checked with lsusb to ensure that the host is recognizing the target device)
  • The device is in recovery mode

From what I can tell it’s not a simple hardware problem, I’ve tested multiple cables but to no avail. I can also attach the log files for a more in depth error message, if needed.

Hi,

did you select the correct device type when running SDK Manager?
(Like, you can check it with contents given by lsusb, and select the corresponding one in SDK Manager)

Also, I don’t think we have JetPack 3.6.2.
What’s the exact version you are using?

Yes, I double-checked it was TX2, the sdkmanager recognized the device, so I didn’t have to do much.

Oh, I mistyped. I’m using 4.6.2 - Fixed the title/ content as well.

Hi,

are you using a real host PC, or a virtual machine?
Does switching to 4.6.3 make any changes?

Thanks for the prompt reply Dave!

Host machine, and not yet - I can try that right now, and let you know.

Hello Dave,

I ran the 4.6.3 as requested, however, it’s still failing in the same part. The error message is similar to the one that I posted above. I see a few message like this:

10:27:08 INFO: Flash Jetson TX2 - flash: [ 4080.2972 ] tegradevflash_v2 --iscpubl
10:27:09 INFO: Flash Jetson TX2 - flash: [ 4081.3214 ] tegrarcm_v2 --isapplet
10:27:09 INFO: Flash Jetson TX2 - flash: [ 4081.3264 ] CPU Bootloader is not running on device.

and a final notice with this:

10:27:20 ERROR: Flash Jetson TX2 - flash: Error: None of the bootloaders are running on device. Check the UART log.
10:27:20 ERROR: Flash Jetson TX2 - flash: command terminated with error
10:27:20 SUMMARY: DateTime Target Setup - target: Depends on failed component

Any ideas why this might happen? Or how to go about it to fix it?

Hi,

then can you help to dump UART log when the flashing process fails, as shown in this post?
