Now I’d like to enable super mode.But I don’t know the difference between jetson-orin-nano-devkit-super.conf and jetson-orin-nano-devkit-super-maxn.conf.Which one will I choose?What’s the difference?

To enable Super Mode on your Jetson Orin NX, you need to choose between two configuration files: jetson-orin-nano-devkit-super.conf and jetson-orin-nano-devkit-super-maxn.conf. While both files are used to enable Super Mode, there are some differences between them.

Similarities:

  • Both files are used to enable Super Mode on Jetson Orin NX.
  • Both files have a higher power budget compared to the standard configuration.
  • Both files support extended clock-frequency steps.

Differences:

  • Power Budget: jetson-orin-nano-devkit-super.conf has a power budget of 25W, while jetson-orin-nano-devkit-super-maxn.conf has a power budget of 40W.
  • Clock Frequencies: The maximum frequencies of CPU, GPU, DLA, and EMC are different between the two files. jetson-orin-nano-devkit-super-maxn.conf has higher maximum frequencies for these components.
  • EMC, SCF, and Hub Clocks: The maximum frequencies of EMC, SCF, and hub clocks are different between the two files. jetson-orin-nano-devkit-super-maxn.conf has higher maximum frequencies for these components.

Which one to choose:

If you need a higher power budget and higher clock frequencies, choose jetson-orin-nano-devkit-super-maxn.conf. However, if you don’t need the highest power budget and clock frequencies, jetson-orin-nano-devkit-super.conf might be sufficient.

Note: The Jetson Orin NX 16GB Super configuration table shows that the jetson-orin-nano-devkit-super-maxn.conf file is not available for this module. Instead, you can use the jetson-orin-nx-devkit-super.conf file, which has a power budget of 40W and supports extended clock-frequency steps.

In summary, while both files are used to enable Super Mode on Jetson Orin NX, jetson-orin-nano-devkit-super-maxn.conf has a higher power budget and higher clock frequencies compared to jetson-orin-nano-devkit-super.conf. Choose the file that best suits your needs.

Hi 592803276,

Are you using the devkit or custom board for Orin NX?

You have compared their difference that they will use different BPMP-DTB for the different power/clock configurations.
MAXN is an unconstraint mode rather than the best performance mode.
We would suggest just using the super mode config to flash(jetson-orin-nano-devkit-super.conf) for better stablility.

I am using custom board.

Thanks for your advice.I will use the jetson-orin-nano-devkit-super.conf to flash our device.Is the command is right below?

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --network usb0 jetson-orin-nano-devkit-super internal

From Jetpack 6, please use generic instead of t186ref.
It seems you want to flash and boot from NVMe, so the full command may be like the following:

$ sudo ADDITIONAL_DTB_OVERLAY_OPT="BootOrderNvme.dtbo" ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -p "-c ./bootloader/generic/cfg/flash_t234_qspi.xml" -c ./tools/kernel_flash/flash_l4t_t234_nvme.xml --showlogs --network usb0  jetson-orin-nano-devkit-super internal
