Hi,
I have successfully compiled the kernel without the config: CONFIG_DEBUG_FS=y. But when I enable it, the compiling became failed. The error information shows below:

The whole log and the config file is attached.

I have learned the post [Orin dev kit] kernel compile error：FAILED unresolved symbol udp6_sock, and browsed on google for a long time, but did not get any help.
If need anything more, please let me know.

Any help will be grateful.

Dear @haomiao.wang,
May I know if you are using DRIVE AGX Orin Devkit or platform based on DRIVE Orin?

7

I use platform. But the error is occur at cross compiling.

8

Dear @haomiao.wang,
Are you using the DRIVE OS 6.0.4 installed using sdkmanager with Devzone credentials? The logs looks like a sepearte release. Please confirm it.
FYI, This forum is intended to support issues related DRIVE AGX Orin Devkit with devzone releases.

9

Yeah, We have a Devzone credentials. This develop kit is be used on our cars.

@SivaRamaKrishnaNV Hello, I find an interesting thing. The config CONFIG_DEBUG_INFO_BTF and CONFIG_DEBUG_FS can only enable either one. But it will be compiled failed when you enable that two meanwhile.

12

Dear @haomiao.wang,
I see below command in compile_error.log
lotus@ubuntu:~/sda/ad4/lambda/lambda_image_src/6040_sdk/ipu04_soc_linux$ ./zfuse_build.sh host -j40 LOTUS_SOC_V6040_ADMC_V5.4.1A_PP-J1-EU-CS_20230519 LOTUS_sign

This script is not part of DRIVE OS 6.0.4 Devzone release.

The kernel compilation instructions are at Compiling the Kernel (NVIDIA DRIVE OS Linux) | NVIDIA Docs . Please see if it helps.

13

@SivaRamaKrishnaNV Yeah, this script is used for generating our filesystem image. But it doesn’t matter, it will execute make kernel image. The important things is the .updated.defconfig. In the compile_error.log, you just only concern the line which I post on:

FAILED unresolved symbol udp6_sock

Just as I mentioned, The compile can be succeed when only enable either CONFIG_DEBUG_INFO_BTF or CONFIG_DEBUG_FS.
Can you take a try please?

14

Dear @haomiao.wang,
I am just trying to understand if you are trying to perform the same steps provided in Compiling the Kernel (NVIDIA DRIVE OS Linux) | NVIDIA Docs or you are trying some thing else.

Also, May I know If it is P3710 or something else (like IPU04 ECU)?

16

Dear @SivaRamaKrishnaNV,
Yeah, I have tried the Docs you mentioned step by step, but it also shows a similar result:

FAILED unresolved symbol netlink_sock

The whole log is attached.
6040_compile_error.log (467.1 KB)

By the way, It seems the bug of DRIVE OS 6.0.4. It is ok with DRIVE OS 6.0.6. You can have a try with the config CONFIG_DEBUG_INFO_BTF=y and CONFIG_DEBUG_FS=y meanwhile using DRIVE OS 6.0.4.

Yes, our ECU is IPU04.

17

Dear @haomiao.wang,
So, the issue is resolved after upgrading to DRIVE OS 6.0.6.

18

@SivaRamaKrishnaNV , Yeah, thanks for your time.
