Hi, I want to update my Jetson Orin Nano from JP 6.2.1 to JP 6.2.2 without losing any user data (Since I use it basically as a normal PC now), I saw that it is possible to update it using apt update and some apt source edit, I just want to know that is there any thing I need to know about this. Also, will L4T 36.5.0 fix the memory issue on 36.4.7?

Updating your Jetson Orin Nano from JetPack (JP) 6.2.1 to JP 6.2.2 without losing any user data is possible, but it’s essential to understand the process and potential implications.

Method 1: Using apt update and apt source edit

You can update your Jetson Orin Nano using the apt package manager. This method involves editing the /etc/apt/sources.list file to point to the new JP 6.2.2 repository and then running apt update and apt full-upgrade to update the system.

Here are the general steps:

  1. Edit the /etc/apt/sources.list file to point to the JP 6.2.2 repository.
  2. Run apt update to update the package list.
  3. Run apt full-upgrade to upgrade the system to JP 6.2.2.

Important considerations:

  • Make sure to backup your user data before attempting the update, as it’s always a good idea to have a backup in case something goes wrong.
  • Be aware that this method may not update the Linux kernel, which is a critical component of the system. If you need to update the kernel, you may need to use a different method.
  • This method may not update the device tree, which is specific to the Jetson Orin Nano hardware.

Method 2: Using Image-Based Over-the-Air (OTA) Update

Another method to update your Jetson Orin Nano is by using the Image-Based Over-the-Air (OTA) Update feature. This method involves flashing a pre-generated image to the device’s partitions, which can update the system, including the Linux kernel and device tree.

To use this method, you’ll need to:

  1. Download the JP 6.2.2 image for your Jetson Orin Nano from the NVIDIA website.
  2. Follow the instructions in the “Updating Jetson Linux with Image-Based Over-the-Air Update” section to flash the image to your device.

Important considerations:

  • This method will erase all user data on the device, so make sure to backup your data before attempting the update.
  • This method will update the Linux kernel and device tree, which may resolve any issues related to these components.

L4T 3650 and memory issue on 3647

Regarding the memory issue on L4T 3647, it’s not clear if L4T 3650 will fix the issue. However, L4T 3650 is a newer version of the Linux kernel, and it may include bug fixes and improvements that could potentially resolve the memory issue.

To determine if L4T 3650 fixes the memory issue, you can try updating to JP 6.2.2 using the Image-Based Over-the-Air (OTA) Update method, which will update the Linux kernel to L4T 3650. If the issue persists, you may need to investigate further or seek support from NVIDIA or the Jetson community.

In summary, updating your Jetson Orin Nano from JP 6.2.1 to JP 6.2.2 without losing user data is possible using the apt package manager, but it’s essential to understand the process and potential implications. Alternatively, you can use the Image-Based Over-the-Air (OTA) Update feature, which will update the system, including the Linux kernel and device tree, but will erase all user data.

Could you provide more information about image-based OTA? Because I don’t see stuff about it in the docs
