Missing gs_usb kernel module for Jetpack 6

Hi,

I have updated to Jetpack 6, however, I got the error when I enabled gs_usb kernel by “sudo modprobe gs_usb”. The error is: “modprobe: FATAL: Module gs_usb not found in directory /lib/modules/5.15.122-tegra”.

I also checked the kernel on Jetpack 5.1.2, It works well for my robot. Will the kernel add to this update?

Thanks,

Hi,
The kernel configs may be enabled in default K5.15. Please enable it and rebuilt kernel image.

Thanks for replying. How can I enable the default kernel and build it?

Hi,
Please refer to Kernel section in developer guide:
Kernel — NVIDIA Jetson Linux Developer Guide 1 documentation

What I did:

Defconfig for Jetpack 5.1.2:

  • Download the sources for Jetpack 5.1.2
  • Open the defconfig file ~/Downloads/jetson_35_4_1_public_sources/Linux_for_Tegra/source/public/kernel/kernel-5.10/arch/arm64/configs/defconfig
  • Or download it here: defconfig.jetpack_5_1_2.txt (32.2 KB)
  • Search the file to see if the module you are missing in Jetpack 6.0 is present in Jetpack 5.1.2, in my case:
    • CONFIG_INPUT_UINPUT=y
    • CONFIG_INPUT_JOYDEV=y

Then sync the kernel sources for Jetpack 6.0 DP following the developer guide:

  • cd ~/nvidia/nvidia_sdk/JetPack_6.0_DP_Linux_DP_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/source
  • ./source_sync.sh -k -t jetson_36.2
  • Open the defconfig file ~/nvidia/nvidia_sdk/JetPack_6.0_DP_Linux_DP_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra/source/kernel/kernel-jammy-src/arch/arm64/configs/defconfig
  • For reference, you can download it here: defconfig.jetpack_6_0.txt (30.4 KB)
  • Check if the modules that were available for Jetpack 5.1.2 are also present for Jetpack 6.0. If not, add the configs at the bottom of the file and save. In my case I added at the bottom:
    • CONFIG_INPUT_UINPUT=y
    • CONFIG_INPUT_JOYDEV=y

Then proceed building the Jetson linux kernel.

In my case, I also needed to install the following packages to build the kernel:

sudo apt install flex bison libssl-dev

Then continue with Flashing the Jetson:

  • cd ~/nvidia/nvidia_sdk/JetPack_6.0_DP_Linux_DP_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra
  • sudo tools/l4t_flash_prerequisites.sh
  • Set the Jetson in recovery mode with the jumper cable, connect USB-C cable to host pc, power Jetson.
  • Verify on host pc with lsusb that Jetson is connected in recovery mode, showing device “NVidia Corp”
  • sudo ./nvsdkmanager_flash.sh
