Unable to re-flash unitree go2 expansion dock. (nvidia orin nx) which has jetpack5.1

[dileep.m]

hey guys.

due to some reasons GPU driver stack got destroyed in unitree go2 expansion dock (nvidia orin nx), as per my research, i need to re-flash the jetpack with 5.1, with ubuntu 20.04 to get the correct GPU drivers in order to run my application.

so am facing issue in re-flashing the same jetpack. from debugging port.

is it recommended to do disassemble the expansion dock and short FC and GND to get into recorvery mode and re-flash?)

Based on the provided context, it appears that you are experiencing issues with the GPU driver stack on your Jetson Orin NX device, specifically with the Unitree Go2 expansion dock. You are considering reflashing the Jetpack with version 5.1 and Ubuntu 20.04 to obtain the correct GPU drivers for your application.

Before proceeding with reflashing, it’s essential to understand the risks involved and the recommended approach. Reflashing the Jetpack can potentially brick your device if not done correctly.

The recommended approach for reflashing the Jetpack on a Jetson Orin NX device is to use the recovery mode. To enter recovery mode, you need to short the FC (Force Recovery) and GND (Ground) pins on the device. However, this requires disassembling the expansion dock, which may void your warranty.

Alternatively, you can try using the debugging port to reflash the Jetpack. This approach is less invasive and does not require disassembling the expansion dock. However, it may not be possible to enter recovery mode through the debugging port if the device is not responding.

Comparing the two approaches:

• Disassembling the expansion dock and shorting the FC and GND pins:
  • Pros: May be more likely to enter recovery mode and successfully reflash the Jetpack.
  • Cons: Requires disassembling the expansion dock, which may void your warranty and potentially damage the device.
• Using the debugging port:
  • Pros: Less invasive and does not require disassembling the expansion dock.
  • Cons: May not be possible to enter recovery mode through the debugging port if the device is not responding.

It is recommended to try using the debugging port first, as it is a less invasive approach. If this method does not work, you may need to consider disassembling the expansion dock and shorting the FC and GND pins. However, this should be done with caution and only if you are comfortable with the risks involved.

Before attempting to reflash the Jetpack, make sure you have:

1. Downloaded the correct Jetpack version (5.1) and Ubuntu 20.04 image.
2. Verified that your device is compatible with the new image.
3. Backed up any important data on the device.
4. Followed the recommended reflashing procedure for your device.

It’s also recommended to consult the official NVIDIA documentation and seek guidance from the NVIDIA community or support team before attempting to reflash the Jetpack.

Hi,
We would suggest consult with the board vendor for support. We don’t use the board and cannot provide further suggestion.
