How should I compile UFEI, KERNEL, and rootfs?

How should I compile a Custom UFEI, KERNEL, and rootfs? I have now installed sdkmanagement and downloaded the source code by running “sudo./source_sync. sh”, but I see that the kernel-5.10 directory is empty. How should I manually compile these firmware.
It would be best if you could provide me with an automatically compiled script
thanks

Hi chutianwei01,

Are you using the devkit or custom board for Xavier NX?
What’s your Jetpack version in use?

You should specify the version tag during sync the source.
Please refer to Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation for details.

I am using version 35.5, and new I checked out the source code by running “source_sync. sh - t jetson_15.5” and compiled Image by running “./nvbuild. sh”. However, I see that there are still nvgpu, nvidia, and hardware directories in the kernel directory. Can Xavier NV use the code from these directories?

你要不要用中文問
實在看不太懂你的問題是什麼

我用的 JetPack 5.1.3 sdkmaneger安装的Jetson Linux R35.5.0，按照文档步骤现在可以编译Image了，但是我发现kernel源代码路径下有hardware、kernel-5.10、nvgpu、nvidia，所以Xavier NX编译Image时，除了用kernel-5.10目录，其他三个目录会用到吗？

剩下的目錄是device tree還有display driver和其他的device driver，都會用到
script會幫你處理好build kernel的步驟，每個目錄放什麼你不知道也無所謂
