Flashing Issue with JetPack 6.2 on Jetson Orin Nano - Timeout & USB Detection Errors

System Information:

  • Host Machine: Ubuntu 22.04
  • JetPack Version: 6.2
  • Target Device: Jetson Orin Nano (8GB Developer Kit)
  • SDK Manager Version: 2.2.0.12028 (or specify your version)

Issue Summary:

I am trying to flash JetPack 6.2 onto my Jetson Orin Nano Developer Kit, but I am encountering persistent timeout errors and connection issues, even when using an Ethernet connection.

Errors Encountered:

1. Timeout Errors During Flashing

When attempting to flash the device through SDK Manager, the process repeatedly times out. The error message states:

ERROR: Flash Jetson Linux - flash: Timeout error: Failed to communicate with the target
  • I tried different USB ports and cables, but the issue persists.
  • Even when the device is properly in recovery mode (lsusb shows 0955:7523 NVIDIA Corp. APX), the SDK Manager fails to detect the device reliably.

2. Ethernet Connection Also Fails

Since the USB connection was unstable, I attempted to connect via Ethernet, but I still receive the same timeout error.

  • Network is properly configured, but the flashing process does not progress.
  • I ensured that the host machine has internet access during installation.
  • I tried disabling the firewall on my system, but the problem persists.

3. USB Detection Issues & Recovery Mode Problems

  • The device enters recovery mode successfully (lsusb lists the device as 0955:7523 NVIDIA Corp. APX).
  • However, SDK Manager fails to establish a stable connection, leading to:

ERROR: Flash Jetson Linux - flash: The connected Jetson device is not ready for flash.
The issue is likely related to a non-optimal USB connection.


* Tried different ports, cables, and even a **USB hub**, but **nothing worked**.

**4. Additional Errors Related to Kernel Image**

Before facing these connection issues, I also encountered:

ERROR: Flash Jetson Linux - flash: gzip: /home/zeynep/nvidia/nvidia_sdk/JetPack_6.2_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/kernel/Image: not in gzip format


* I manually re-compressed `Image.gz` and copied it to `/boot/`, but this did not resolve the flashing failure.

### **Next Steps Taken:**

Since the automatic download process was unreliable, I decided to **manually download some of the missing files** and place them in the correct directories under `sdkm_downloads`.

However, **I need to know the correct way to manually download missing JetPack 6.2 components** and ensure they are properly recognized by SDK Manager.

**Questions:**

1. Why am I facing **persistent timeout errors** even when using **Ethernet**?
2. What could be causing the **Jetson Orin Nano to disconnect during flashing**, despite being in **recovery mode**?
3. Are there **alternative ways to flash the device manually**, bypassing SDK Manager if necessary?
4. How can I **manually download and place** the required `sdkm_downloads` files to avoid repeated failed downloads?

Any guidance on these issues would be greatly appreciated. Thank you!

Hi,

We need you full flash log and serial console log to find the reason.

To record a serial console log, please refer to

Also some questions to confirm

  • Is your ubuntu a native or a virtual machine (e.g VMware, VirtualBox …)

Thanks
