Questions regarding Jetson kernel build (Jetpack 5.0.2) on Xavier NX

user11350 · April 6, 2023, 7:18pm

Jetson Xavier NX dev kit running Jetpack 5.0.2 (5.10.104-tegra)

We are trying to add a USB module to the board and that requires some additional driver and kernel build. We manually downloaded kernel source from Nvidia’s site and extracted it. And then load config and modified it accordingly:
tar -xjf public_sources.tbz2
cd Linux_for_Tegra/source/public
tar -jxvf kernel_src.tbz2
make tegra_defconfig
gedit .config

Next when we tried to run the provided build script nvbuild.sh, it always says the source tree is not clean, and asks for make mrproper. But make mrproper will remove the .config file…Are we doing it right? Or did we miss something?

We tried to build kernel without using that script under /kernel/kernel-5.10
But we feel like when we run “make dtbs”, dtb weren’t built properly. How can we tell whether it’s built properly or not? And where are the built files without specifying an output directory?

The output is like this:

interpl@interpl-nx1:~/public_release/Linux_for_Tegra/source/public/kernel/kernel-5.10$ make ARCH=arm64 LOCALVERSION=-tegra -j4 dtbs

Some random related comments, not necessarily the issue…

On a running system, use the command “uname -r”. Find the suffix of that. As a contrived example, if it says “5.15.0-tegra”, then the 5.15.0 is from the kernel source code, and the suffix is “-tegra”. Make sure in your .config you set:
CONFIG_LOCALVERSION="-tegra"

Otherwise, your module won’t match. However, before you start any of your build, try “make mrproper” once to make sure the starting source is completely unconfigured. Then you can run the “make tegra_defconfig”. Do not manually edit the .config unless you absolutely know the change has no dependencies…I happen to know that CONFIG_LOCALVERSION has no dependencies. Use an editor, for example “make nconfig” (which has a nice symbol search function) to make most changes since editors intended for this purpose understand dependencies. Then try again.

Also, be sure to mention when native compiling versus cross compiling. Provide the compiler release version, e.g., “gcc --version” (or the cross compiler with “--version” if cross compiling).

Yes, mrproper will remove the .config. I don’t really use the nvbuild.sh script, but notes about configuring should still be correct. However, there is a twist to this tale: If the script (or you) use the “O=/some/where” option, then this location is where everything goes, including the .config. Any configuration in the actual source code (the “$TOP”) would have to be avoided…and the best way to do that is with the mrproper command, and having the “O=/some/where” be a completely empty directory. Having a change in both the output location (the “O=” parameter, if used) and the “$TOP” would be a conflict, e.g., you might get the note on needing mrproper.

Thank you for your response!
We are building on Jetson board.
uname -r returns 5.10.104-tegra
gcc --version returns gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

We tried to build it again over the weekend. And it seems like output directory mismatch was indeed causing that problem. We assigned kernel_out as the output directory and ran the nvbuild.sh script. Even though the make dtbs portion gave similar output than before, the script returned “Kernel source compiled successfully”. Are we supposed to copy kernel_out/arch/arm64/boot/Image, kernel_out/arch/arm64/boot/dts/nvidia/* to Jetson’s /boot directory to install kernel and device tree? Under kernel_out/arch/arm64/boot/dts/nvidia/ directory there are dozens of .dtb and .dtbo files.

What about kernel modules?
This is our first time working on this kind of task… We feel like most of them are very basic… But we just want to make sure we are doing it right… Thanks!

Hi, glad to see you built it successfully, and also sorry for not leaving a reply before.
As you say, just replace the files as specified in To Build the Kernel, and reboot the device.
It should load the new customized kernel and device tree upon reboot.

linuxdev · April 11, 2023, 12:59pm

FYI, I always keep the original kernel Image file, and install the kernel_out/arch/arm64/boot/Image with a modified name, e.g., I might install this to the Jetson as “/boot/Image-custom-$(uname -r)”.

Note that when you build Image it also propagates configuration for a number of other targets. If you skip Image target, be sure to run the modules_prepare target before building anything else (and ignore modules_prepare if you’ve built Image). You will also be interested in these targets:

modules
dtbs

Assuming configuration is correct, and that you have “O=/some/where”, then you can also extend that concept by adding “INSTALL_MOD_PATH=/new/module_location” as an empty directory:
make O=/some/where modules_install INSTALL_MOD_PATH=/new/module_location

Or, for firmware, if you have “INSTALL_FW_PATH=/new/firmware”:
make O=/some/where firmware_install INSTALL_FW_PATH=/new/firmware

I’ll reemphasize that building Image does more than building the kernel…it also sets up configuration for other targets. So if you’ve built Image, then those other targets should work as expected when the location of output has been set to an empty directory. Those locations then mirror the directory structure as to where to find things and where to install them on the Jetson.
