We are working on Orin NX 8GB, which could operates up to 40W.
We’ve designed a custom carrier board, at the beginning we designed such that VDD_IN is 5V for Orin NX module input. We could config the board into super mode MAXN_SUPER. However the maximum current input is 5A only, as a result it could achieve only up to 25W.
Now we try to modify our carrier board design to set module_id equals to 1. The board now could accepts a higher VDD_IN and we are able to configure the board to operate at 40W power profile.

To enable Super Mode on your Jetson Orin NX 8GB module, you need to ensure that your custom carrier board design meets the necessary requirements.
Initially, you designed the carrier board with a 5V VDD_IN input, which limited the maximum current to 5A and resulted in a maximum power consumption of 25W. To achieve the 40W power profile, you modified the carrier board design to set the module ID to 1, allowing for a higher VDD_IN input.
However, after making this change, you encountered issues enabling MAXN_SUPER mode. To resolve this, you should verify that your carrier board design meets the following requirements:
HV rail: Ensure that your carrier board has an HV rail to enable Super Mode. This is a necessary requirement for the Orin NX series.
Thermal design: Verify that your thermal design can support the 40W power profile. This may involve adjusting the cooling system or heat sink to ensure adequate heat dissipation.
Power supply: Confirm that your power supply can provide the necessary voltage and current to support the 40W power profile. As mentioned in the documentation, MAXN_SUPER at 40W for Jetson Orin NX requires a minimum of 8.0V to the VDD_IN.
Regarding the error message you encountered when trying to enable Super Mode in jtop or through the command line, it’s possible that the issue is related to the module ID change. When you set the module ID to 1, you may need to update the flash configuration file to reflect this change.
To troubleshoot the issue, you can try the following:
Verify the flash configuration file: Ensure that the flash configuration file is updated to reflect the module ID change. You can check the file by running the command sudo cat /sys/firmware/devicetree/base/module_id.
Check the power budget: Verify that the power budget is set correctly. You can check the power budget by running the command sudo cat /sys/kernel/debug/bpmp/debug_info.
Enable Super Mode manually: Try enabling Super Mode manually by running the command sudo nvpmodel -m 1. This will set the module to mode 1, which corresponds to the 40W power profile.
If you continue to encounter issues, you may want to consult the Jetson Orin NX documentation and seek further assistance from NVIDIA support or the developer community.
