Does Orin Nano support Cold restart?

Issue Overview

The discussion revolves around whether the Nvidia Jetson Orin Nano Dev board can perform a cold restart, which is defined as a reboot involving a complete power off and then power on sequence. Users have confirmed that the system supports shutdown, suspend, and warm restarts (reboots without cutting power). However, the main concern is whether a cold restart is feasible with this hardware.

Symptoms or Errors:

• Users are questioning the capability of performing a cold restart.
• There is no clear answer provided within the forum, leading to confusion.

Context:

• The issue arises during discussions about system capabilities and operational features.
• Users are likely exploring this functionality for specific applications or development scenarios where power cycling may be necessary.

Hardware/Software Specifications:

• The discussion specifically pertains to the Nvidia Jetson Orin Nano Dev board.

Frequency of the Issue:

• This appears to be a common question among users, indicating a general uncertainty regarding the hardware’s capabilities.

Impact on User Experience:

• The inability to perform a cold restart could hinder certain development processes or testing scenarios that require complete power cycling.

Possible Causes

• Hardware Limitations: The hardware may not be designed to support cold restarts, which could lead to permanent states or configurations that do not allow for such operations.

• Firmware Constraints: The firmware may not include routines that handle cold restarts effectively, limiting the board’s operational flexibility.

• User Misunderstanding: Users may confuse cold restarts with other types of reboots, leading to false expectations about functionality.

Troubleshooting Steps, Solutions & Fixes

1. Confirm Current Capabilities:

   • Check the official Nvidia documentation for the Jetson Orin Nano to understand its supported functionalities.
   • Review any release notes or updates that may address this feature.

2. Testing Power Cycling:

   • Attempt to perform a manual cold restart by completely powering off the device and then turning it back on.
   • Observe if the system resumes normal operation post-cold restart.

3. Review Community Insights:

   • Engage with community forums for shared experiences regarding cold restarts on similar devices.
   • Reference discussions that may provide insights or workarounds related to power management features.

4. Driver and Firmware Updates:

   • Ensure that all drivers and firmware are up-to-date. This can sometimes resolve unexpected behavior related to power management.
   • Use the command:

     sudo apt update
     sudo apt upgrade
     

5. Document Findings:

   • If issues persist, document any error messages or behaviors encountered during attempts at cold restarting.
   • Share this information in forums for further assistance from community members or Nvidia support.

6. Explore Alternative Solutions:

   • If cold restarting is critical for your application, consider using external hardware solutions (e.g., smart plugs) that can manage power cycling effectively.

7. Best Practices:

   • Regularly check for updates from Nvidia regarding new features or fixes that might enhance functionality related to power management.
   • Engage with user communities to stay informed about best practices and troubleshooting tips.

Note: As of now, there appears to be no hardware support for cold restarting as per user feedback in the forum. Further investigation may be needed if new updates or community findings emerge.
