Jetson orin nx unable to perform flash sdk(5.1.1) ssd

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin NX

Hello:

I am currently using jetpack 5.1.1 SDK for kernel development on the Jetson Orin NX platform. However, I found that I am unable to flash the device. After checking, I discovered that the reason is due to a PCN change, but I don’t know how to modify it. Could you please help me take a look?

To address your issue with flashing the Jetson Orin NX device using Jetpack 5.1.1 SDK, we need to consider the PCN (Product Change Notification) change that’s causing the problem.

Firstly, let’s understand what PCN is. PCN is a notification sent by NVIDIA to inform customers about changes to their products, including hardware, software, or documentation. These changes can affect the functionality, performance, or compatibility of the product.

In your case, the PCN change is likely related to the hardware configuration of the Jetson Orin NX module. To resolve this issue, you’ll need to update the device tree configuration to match the new PCN.

Here are the steps to modify the device tree configuration:

  1. Identify the PCN change: Check the NVIDIA documentation or contact NVIDIA support to determine the specific PCN change that’s affecting your device.
  2. Update the device tree configuration: Modify the device tree source file (.dts or .dtsi) to reflect the changes specified in the PCN. You can find the device tree source files in the hardware/nvidia/platform/t23x/common/kernel-dts directory of the Jetpack SDK.
  3. Recompile the device tree: After updating the device tree configuration, recompile the device tree binary using the dtc compiler.
  4. Update the kernel configuration: If the PCN change affects the kernel configuration, update the kernel configuration file (config) to reflect the changes.
  5. Rebuild the kernel: Recompile the kernel using the updated kernel configuration.

To flash the device, you can use the flash.sh script provided in the Jetpack SDK. Make sure to specify the correct device tree configuration and kernel image when running the script.

Here’s an example command to flash the device:

sudo ./flash.sh jetson-orin-nx-devkit mmcblk0p1

Replace mmcblk0p1 with the actual device name of your SD card or eMMC storage.

If you’re using a custom carrier board, you may need to update the device tree configuration to match your board’s specific hardware configuration.

In comparison to the Jetson Orin Nano, the Jetson Orin NX has a different device tree configuration due to its unique hardware features. Therefore, you’ll need to update the device tree configuration specifically for the Jetson Orin NX.

To summarize:

  • Identify the PCN change affecting your device
  • Update the device tree configuration to match the PCN change
  • Recompile the device tree and kernel
  • Flash the device using the updated device tree and kernel configuration

If you’re still experiencing issues, please provide more details about the error messages or symptoms you’re seeing, and I’ll be happy to help you troubleshoot further.
