Facing the below errors while building the kernel for Javier NX module

Hi,
Please make sure you link to this toolchain for building source code:
https://developer.nvidia.com/embedded/linux-tegra-r3261

GCC 7.3.1 for 64 bit BSP and Kernel

Seems like you probably link to gcc of Ubuntu 22.04

17

OK. will check this. BTW,

How to clean the kernel and compile fresh one.

This command “sudo ./nvbuild.sh -o $PWD/kernel_out” i am using for compile

Hi DaneLL

I did not see the previous errors. But I see the below error. Could you check?

Hi,
Please try the manual steps in
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/kernel_custom.html#wwpID0E0WD0HA
See if it works by executing the commands step by step.

Hi,

Sorry if there were any misunderstandings, but I just saw that the post helped you so I’m jumping here again.

For the other errors, here is another post that might help:

Change nvbuild.sh on line 86:
from

O_OPT=(-O “${KERNEL_OUT_DIR}”)

to

O_OPT=(O=“${KERNEL_OUT_DIR}”)

Regards

21

I tried this and it did not help for me.

22

Regarding the above error, that file is generated from a “make Image” command (adjusted for path and tools, e.g., the “O=/some/where/temporary” would change the $TOP for output of content during a build). I don’t know about the particular firmware build command you used, but if it requires the Image file, then perhaps it is as simple as building the Image target (configured correctly) and then firmware might build.

23

I am getting this error “gcc: error: unrecognized command-line option ‘-mlittle-endian’” While trying the manual steps. Could you check?

24

NVIDIA team,

Can someone please help to build the kernel build?? I am really struggling to build this kernel for R-32.7.3.

I do not want any suggestions (all are not working). someone please try from your end and let me know

I am using ubuntu 18.04 image.

Your documentations are not working as expected.

25

Hi,
We have verified the steps on host PC in Ubuntu 18.04 and 16.04, so if you have host PC in same OS version, it is supposed to work. For the previous post, it looks like you use Ubuntu 22.04 and this may be the deviation triggering the failure.

Or you may try to build it directly on Xavier NX developer kit. See if this works at your end.

26

I removed the VMware and using the HOST-PC Ubuntu 18.04 version.

I do not want to use the kit. Since all the developer will use this ubuntu.

The problem is nothing is copied into “kernel_out” directory

27

Hi DaneLLL

Any updates??

28

Hi,
Please try the manual steps in developer guide

Share my PATH setup for reference:

$ export TEGRA_KERNEL_OUT=/home/danel/temp/jetp/jp463/Linux_for_Tegra/source/public/kernel_out/
$ export CROSS_COMPILE=/home/danel/gcc_tools/jp4/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
$ export LOCALVERSION=-tegra

My <kernel_source> is /home/danel/temp/jetp/jp463/Linux_for_Tegra/source/public/kernel/kernel-4.9

29

I compared the 35.2 and 32.7 release nvbuild.sh files and moved the diff. Now its compiling.

Now now doubts is in the nvidia documents Kernel Customization — Jetson Linux<br/>Developer Guide 34.1 documentation its mentioned to copy the files in the below path but in my case the file are in diff place, for ex:

Replace Linux_for_Tegra/rootfs/usr/lib/modules/$(uname -r)/kernel/drivers/gpu/nvgpu/nvgpu.ko with a copy of this file:
But I see in 32.7.3 this ko file is present in "./rootfs/lib/modules/4.9.299-tegra/kernel/drivers/gpu/nvgpu/nvgpu.ko

"

$kernel_out/arch/arm64/boot/dts/nvidia/

I do not see “nvidia” folder in my kernel build. Is the path correct or do I need to do anything?

I see dtb files are in this path only: ./kernel_out/arch/arm64/boot/dts/

There is no folder under this dir.

Hi,
It looks like the build script does not work properly on Jetpack 4 release. Please try the manual steps.

32

Hi DaneLL,

I followed the steps from the document. Facing the below errors in compilation. Could you check?
“gcc: error: unrecognized command-line option ‘-mlittle-endian’”

Hi,
Do you install the packages:

$ sudo apt install build-essential bc
34

yes. Installed.

I copied these env into kernel/Makefile. Now I am able to compile

export TEGRA_KERNEL_OUT=/home/ayyappan/nvidia/kernel_source/Linux_for_Tegra/source/public/kernel_out
export CROSS_COMPILE=/home/ayyappan/nvidia/kernel_source/Linux_for_Tegra/source/public/kernel/kernel-4.9/tool-chain/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
export LOCALVERSION=-tegra

But, I did not see the nvidia folder inside kernel_out/arch/arm64/boot/dts/nvidia/

where Can I find the dtsi files for this build?

35

Hi,
dtsi files are built into dtb. You should see dtb files in

/home/danel/temp/jetp/jp463/Linux_for_Tegra/source/public/kernel_out/arch/arm64/boot/dts
36

Yes. its there. this is the right path?
