JetPack 3.1 kernel source tag problem

ZhangXin · July 25, 2017, 8:24am

I tried this tag “tegra-l4t-r28.1” and seems that some repos are lack of this tag.

Hi ZhangXin,

We are aware of this tag issue. Please try with sources from https://developer.nvidia.com/embedded/dlc/l4t-sources-28-1 first and we will let you know once tag is fixed.

SirRobert · July 25, 2017, 3:50pm

Hello Vicky, I think the source available at the download link you provided, is still incomplete. I am unable to locate TX2 related device tree files in it. I’m not sure what else is missing. Can you please check?

ZhangXin · July 26, 2017, 1:24am

Hi Vicky,

Besides the DTS problem SirRobert mentioned, I encounter build problem when “make zImage” with the source code from the link you provide.“tegra18_defconfig” is used.

VickNV · July 26, 2017, 1:42am

We are fixing both tag and https://developer.nvidia.com/embedded/dlc/l4t-sources-28-1 issues.
Once ready, we will inform you here.
Sorry for any inconvenience!

WayneWWW · July 26, 2017, 1:45am

Hi SirRobert and ZhangXin,

Sorry for the missing dts file for TX2. We will update it soon.

As for “governor.h”, I saw it under “kernel-4.4/drivers/devfreq”.

ZhangXin · July 26, 2017, 2:54am

Hi WayneWWW,

Thank you for the reply. Do you have an estimation when the tag and kernel source will be ready?

If I change the ‘include <governor.h>’ to ‘include “governor.h”’, the problem seems fixed. However, there are still some similar problems and I think I should wait for your new release instead of solving them by myself. Not sure if it’s an environment problem. Is there any official document on how to compile the kernel? Currently I follow this instruction “Compiling Jetson TX2 source code - RidgeRun Developer Wiki”.

WayneWWW · July 26, 2017, 3:17am

Hi ZhangXin,

Yes, please refer to “L4T Documentation” in Jetson Download Center | NVIDIA Developer.

There is a section named “Kernel Customization”.

forever3000 · July 26, 2017, 4:33am

Hi vickyy,

When I tried to compile kernel, it noticed this problem

In file included from /home/vu/Desktop/Projects/JetsonTX2/kernel_raw_rgb/sources/kernel/kernel-4.4/drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu/gm20b/acr_gm20b.c:22:0:

Do you have any idea ?

Thanks

WayneWWW · July 26, 2017, 4:47am

Hi forever3000,

We have confirm that this package does not include the source for TX2. Anything named “t18x” is for TX2.

I am really sorry about this. The new package will be updated soon.

mmalczak · July 26, 2017, 6:14am

I have similar problems with TX1.

What is more, there is missing “dev.h” file, which is included in /drivers/media/platform/tegra/camera/csi/csi.c"

When can we expect updates?

giuseppepatane · July 27, 2017, 5:19am

I suggest to align tag for u-boot too, otherwise is not possible to sync all source code!
Ok, it’s aligned!

giuseppepatane · July 27, 2017, 5:25am

Please align tag on:
linux-nvgpu-t18x.git
linux-nvhost-t18x.git

Thanks

xiaoyongtijee · July 27, 2017, 3:58pm

I sync’d to tag tegra-l4t-r28.1 and make zImage succeeded, although there are some warnings about section mismatch for vmlinux.0

ZhangXin · July 28, 2017, 1:27am

Hi xiaoyongtijee,

Did you just

./source_sync.sh -k tegra-l4t-r28.1
make tegra18_defconfig
make zImage
and succeeded?

I still encounter some head file missing problems like

CC      drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu/common/linux/kmem.o
drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu/common/linux/kmem.c:30:25: fatal error: gk20a/gk20a.h: No such file or directory
 #include "gk20a/gk20a.h"
                         ^
compilation terminated.
scripts/Makefile.build:261: recipe for target 'drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu/common/linux/kmem.o' failed
make[3]: *** [drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu/common/linux/kmem.o] Error 1
scripts/Makefile.build:406: recipe for target 'drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu' failed
make[2]: *** [drivers/gpu/../../../nvgpu/drivers/gpu/nvgpu] Error 2
scripts/Makefile.build:406: recipe for target 'drivers/gpu' failed
make[1]: *** [drivers/gpu] Error 2
Makefile:973: recipe for target 'drivers' failed
make: *** [drivers] Error 2

I can find the “gk20a.h” file somewhere else and move it to the proper place, however, I don’t think it’s the right way to solve these problem. So I wonder if you just did the above 3 steps.

Thanks.

WayneWWW · July 28, 2017, 3:06am

ZhangXin,

Please try to build the kernel source with instructions in the document. There is a section teaching how to build NV kernel.

https://developer.nvidia.com/embedded/dlc/l4t-documentation-28-1

ZhangXin · July 28, 2017, 3:57am

Hi WayneWWW,

It was my mistake. I thought “make -O=xxxx” was optional, however, it turned out to be mandatory. After adding the “-O=”, the kernel can be built successfully.

Anish1080Ti · July 28, 2017, 3:32pm

Hi,

I don’t understand the way this whole “O=” being mandatory to build zImage and/or modules. I think most of the errors are because a #include <> is used instead of #include “”. Adding -I./$(src) to the relevant Makefile solves the issue.

My point is that building with or withou “O=” shouldn’t matter. Please look into it.

Also, may I please know if t18x related source code has been added to the Sources tarball?

xiaoyongtijee · July 29, 2017, 1:05am

Nice it works.
Yes, I tried with -O first as well and that didn’t work

kayccc · July 29, 2017, 1:16am

The t18x source in the kernel_src tarball issue has been root caused and resolved, those files have been added to the source tarball, please download it again from the link:

[url]https://developer.nvidia.com/embedded/dlc/l4t-sources-28-1[/url]

Thanks
