Failed to restart display after loading self-compiled Image and dtb

I have transplanted the camera driver into the kernel, so there is a little difference with the official R34.1.1 kernel

Try to compile Nvidia’s sources without your changes…

Nothing is changed, and the same is true for compiling the native kernel

Is there any code missing when compiling ???

You wrote about “little difference with the official R34.1.1 kernel”.
So I suggested to compile native sources, obtained by script.
There are only two issue, which resolved in this topic:

I used to download the source code

/net/ethernet/nvidia/nvethernet/ether_linux.h:62:10: fatal error: osi_core.h: No such file or directory

How did you solve it!!

Please check the WAR here…

Why do I still get an error when I create a soft link

ln -s …/…/…/…/…/nvethernetrm nvethernetrm

Same error or something different?

Same error

Is there any solution??

The project is now very urgent!!!

You should create symlink inside kernel/nvidia/drivers/net/ethernet/nvidia/nvethernet.
But you have created symlink inside kernel/nvidia/drivers/net/ethernet/nvidia/

thank you

Unfortunately, I compiled the Image this way (

After replacing /boot with orin

Display still doesn’t show

Still error

Again, this nvidia.ko driver is not compatible


I have used to get sources code and use latest toolchain for L4T34.1.1.
After compiling my own Image without any change of source code, I got same error in this thread:

[    8.957540] nvgpu: Unknown symbol nvlink_shutdown (err -2)
[    8.957782] nvgpu: Unknown symbol nvlink_register_link (err -2)

[    8.984952] nvgpu: Unknown symbol nvlink_train_intranode_conn_safe_to_hs (err -2)

Comparing to L4T_32.7.1, these simpols are in sources/kernel/nvidia/drivers/nvlink/nvlink-core.c, but nvlink-core.c can’t be found in L4T_34.1.1 source folders.

Please help to check if it is missing in github repository for L4T_34.1.1

Note: Using the original Image can get display output without related errors.



That nvlink directory is not in use. It was also redundant in older release


I try to modify nvlink.c and can confirm it is not in use, but I am still not sure where the Unknown symbol error comes from.

please help to advise how to fix the above issue.



Do you only replace your kernel image? or you even replace every other kernel modules?

Only replace kernel image

Then you know what to try now.
