The Jetson Orin NX, like other Jetson devices, supports updating the kernel independently without updating the file system. This is achieved through the use of the device tree plugin and the kernel adaptation process.

According to the provided context, the Jetson Linux kernel can be customized and updated independently of the file system. The kernel adaptation process involves several steps, including obtaining the kernel sources, building the Jetson Linux kernel, and building the NVIDIA out-of-tree modules.

The device tree plugin is also supported on Jetson devices, including the Jetson Orin NX. The device tree structure has changed in Rel-36, and details can be found in the adaptation guide, which includes information on the AGX Orin Device Tree Structure and the Orin NX/Nano Device Tree Structure.

In terms of updating the kernel independently, the Jetson Linux kernel can be updated using the OTA (Over-the-Air) update mechanism. This allows for the kernel to be updated without affecting the file system. However, it’s essential to note that the OTA update mechanism may have specific requirements and limitations, and it’s crucial to follow the guidelines and recommendations provided in the Jetson Linux documentation.

In comparison to other Jetson devices, the Jetson Orin NX has similar kernel adaptation and update mechanisms. However, the specific device tree structure and kernel configuration may vary depending on the device model and revision.

To summarize:

  • The Jetson Orin NX supports updating the kernel independently without updating the file system.
  • The device tree plugin is supported on Jetson devices, including the Jetson Orin NX.
  • The kernel adaptation process involves several steps, including obtaining the kernel sources, building the Jetson Linux kernel, and building the NVIDIA out-of-tree modules.
  • The OTA update mechanism can be used to update the kernel independently of the file system.
  • The specific device tree structure and kernel configuration may vary depending on the device model and revision.

It’s essential to consult the Jetson Linux documentation and follow the guidelines and recommendations provided to ensure a successful kernel update and adaptation process.
