Note: 7-14-2020 The OTA updates issue described here has been fixed! It’s safe to go back into the water. This article will self destruct in a few days.

Over The Air (OTA) updates is one of the new features for the JetPack 4.4 Production Release – L4T 32.4.2. Unfortunately, there are some issues with this feature that people are encountering in the product rollout.

Here’s the money quote from NVIDIA:

Note: We have temporarily disabled the feature of upgrading JetPack or L4T using debian package management tool due to an issue we found in one of our debian packages causing the device to not boot properly. We have identified the root cause and fixing it currently. We will re-enable this feature soon once fixed and update this post.

Please note that one can still install JetPack using SDKM or downloading SD card images (for Jetson Nano and Jetson Xavier NX) from the JetPack page.

The major issue people are reporting is that after a system upgrade, the Jetson boots, but goes to a blank screen with a blinking cursor. You can read through this thread on the Jetson Xavier NX forum: Jetson Xavier NX not booting.

There appears to be a work around, but since these issues are just coming to light the day of the rollout it feels prudent to take this into account before upgrading your system.

Note: If you create a system from a JetPack 4.4 SD card image (on the Jetson Nano and Jetson Xavier NX) or install JetPack 4.4 using the SDK Manager (Jetson AGX Xavier, Jetson TX2), you will not encounter these issues. However, if you issue the commands:

$ sudo apt update
$ sudo apt upgrade

When you reboot the system, you will get a black screen and a flashing cursor, no GUI.

OTA updates is one of the most anticipated features of this release. The folks at NVIDIA are working on this, there should be fixes soon.
