The NVIDIA Jetson TX2 is a powerful platform for AI and embedded computing. However, flashing the board can sometimes present challenges. One common issue involves communication failures with the Boot Rom (Read-Only Memory). This article delves into the intricacies of boot ROM communication errors, specifically focusing on “Return value 3”, and offers potential solutions.
Decoding “Return value 3” in Jetson TX2 Flashing
When flashing a Jetson TX2, errors during the boot ROM communication phase can halt the process. A frequent error message encountered is “Return value 3,” often accompanied by “Boot Rom communication failed” and “Reading board information failed.” This specific error signifies a breakdown in communication between the host computer and the Jetson TX2’s boot ROM. The boot ROM is the first piece of software that runs on the TX2 and is responsible for initializing the hardware and loading the bootloader. A failure at this stage indicates a fundamental problem preventing the flashing process from proceeding.
Common Causes of Boot ROM Communication Failures
Several factors can contribute to boot ROM communication issues:
- Driver Issues: Incorrect or outdated USB drivers on the host computer can prevent proper communication with the Jetson TX2. Ensuring the latest NVIDIA drivers are installed is crucial.
- VMware Compatibility: Using virtual machines (VMs) for flashing can introduce complexities. While VMware generally supports USB passthrough, compatibility issues can arise, hindering communication with the boot ROM. Using a native Ubuntu installation is often recommended for a more stable flashing process.
- USB Connection Problems: A faulty USB cable or port can disrupt communication. Trying different cables and ports can help isolate this issue. Ensure the Jetson TX2 is connected to a USB 2.0 port, as USB 3.0 is not supported during this phase.
- Incorrect Recovery Mode: The Jetson TX2 must be in recovery mode (also known as Force Recovery Mode) for successful flashing. This usually involves holding down a specific button while powering on the device. Refer to the official NVIDIA documentation for the correct procedure.
- RCM Version Discrepancies: Variations in the RCM (Recovery Mode) version might indicate underlying compatibility issues between the flashing tools and the specific Jetson TX2 board revision.
- Corrupted Images: A corrupted Jetson TX2 image file can lead to errors during the flashing process. Downloading a fresh image from a reliable source is recommended.
Troubleshooting Steps
To address “Return value 3” and other boot ROM communication failures, try the following:
- Verify Driver Installation: Confirm that the correct NVIDIA USB drivers are installed on your host computer.
- Use Native Ubuntu: Consider using a native Ubuntu installation instead of a VM for flashing.
- Test Different USB Cables and Ports: Try different USB cables and ports, ensuring you’re using a USB 2.0 port.
- Double-Check Recovery Mode: Carefully follow the official NVIDIA instructions to put the Jetson TX2 into recovery mode.
- Re-download the Image: Download a fresh copy of the Jetson TX2 image file to rule out corruption.
- Consult NVIDIA Forums: Search the NVIDIA developer forums for similar issues and potential solutions. Often, others have encountered and resolved the same problem.
Conclusion
Boot ROM communication errors, particularly “Return value 3”, can be frustrating when flashing a Jetson TX2. By understanding the potential causes and employing the troubleshooting steps outlined above, you can increase your chances of successfully flashing your board and embarking on your AI development journey. If problems persist, contacting NVIDIA support directly is advisable.
