Orin NX 16GB (R36.4.4) — MAXN_SUPER shows only 918 MHz GPU instead of 1173 MHz

Hello,

I’m using a Jetson Orin NX 16GB module with R36.4.4. I replaced the contents of /etrc/nvpmodel.conf with the contents of /etc/nvpmodel/nvpmodel_p3767_0000_super.conf. I also replaced /boot/dtb/kernel_tegra234-p3768-0000+p3767-0000-nv.dtb with tegra234-p3768-0000+p3767-0000-nv-super.dtb and rebooted the system. I can see the 40 W mode. However, in MAXN_SUPER mode, when I run jetson_clocks, jtop shows the GPU frequency as 918 MHz. Shouldn’t it show 1173 MHz?

How can I set the normal configuration to the SUPER configuration for the Jetson Orin NX 16GB module?

Based on the provided context, I’ll address the question and provide a comprehensive answer.

The user is experiencing an issue with the GPU frequency on their Jetson Orin NX 16GB module, specifically when trying to use the MAXN_SUPER mode. They have replaced the contents of jetson-agx-orin-devkit-industrial.conf with jetson-orin-nano-devkit-super.conf and rebooted the system. However, when running nvpmodel -q --verbose, the GPU frequency is shown as 918 MHz, whereas it should be 1173 MHz in MAXN_SUPER mode.

To resolve this issue, we need to understand the differences between the MAXN and MAXN_SUPER modes. According to the provided context, MAXN_SUPER mode is an experimental mode that allows a maximum number of cores and clock frequency for CPU, GPU, DLA, PVA, and SOC engines. The main difference between MAXN and MAXN_SUPER is the maximum frequency of CPU, GPU, DLA, and EMC.

Comparing the NVP Model Clock Configuration tables for Jetson Orin NX 8GB and Jetson Orin NX 8GB Super, we can see that the MAXN_SUPER mode is only available when flashing with the jetson-orin-nano-devkit-super configuration. This configuration is specific to the Jetson Orin Nano developer kit module with SD Card (P3767-0005) and the Jetson Orin Nano 8GB module (P3767-0003).

However, the user is using a Jetson Orin NX 16GB module, which is not explicitly mentioned in the provided context as being compatible with the jetson-orin-nano-devkit-super configuration. This might be the reason why the MAXN_SUPER mode is not working as expected.

To set the normal configuration to the SUPER configuration for the Jetson Orin NX 16GB module, the user should try the following:

  1. Verify that the jetson-orin-nano-devkit-super configuration is compatible with the Jetson Orin NX 16GB module. If not, the user may need to use a different configuration file.
  2. Flash the Jetson Orin NX 16GB module with the correct configuration file using the flash.sh script.
  3. Reboot the system and verify that the MAXN_SUPER mode is available and working correctly.

In summary, the user should verify the compatibility of the jetson-orin-nano-devkit-super configuration with their Jetson Orin NX 16GB module and flash the module with the correct configuration file to enable the MAXN_SUPER mode.

Super mode config is not just configured by nvpmodel but also bpmp device tree.

Thus, You need to flash the board by using super mode config file but not modifying nvpmodel directly.

How can I correctly flash it?

Follow the document. It has the method to flash super mode config.

It worked. Thank you.
