Hello, I’m customizing the kernel r35.31, JetPack 5.1.1 kernel version 5.10.104-tegra [image] Im using intel AX210 wifi inside the config file present in IWLWIFI , IWLMVM,IWLDVM,CFG80211 is made y so as to insert automatically instead of m but module is not inserted lsmod doesn’t show these modules Bluetooth: hci0: Failed to load Intel firmware file intel/ibt-0041-0041.sfi (-110) How to solve this issue to get wifi

Answering ‘y’ integrates the function into a kernel Image file. This is the most difficult and dangerous way to install a driver. Answering ‘m’ sets to module format. This latter creates a .ko file. There will be no .ko for anything integrated/‘y’. Having the driver integrated will also disallow adding a module/‘.ko’ install of the driver (you can’t load the driver twice). I suggest answering ‘m’ after restarting the kernel config from scratch. Then you will get a .ko file and you just have to copy it in then “sudo depmod -a” to inform the kernel that it has a new module. The module won’t actually load until something triggers it.

what should be the steps i should follow to correct this on my customized carrier board

How did you build your ko files out? Are you building it on Jetson or you build it on host PC?

Also, it is easy to understand what is “Disagrees about version of symbol module_layout” error on the Internet. This issue is really not Jetson specific but common kernel building issue.

from a working flashed image with all the kernel source i need to develop a working image from a base SDK , i extracted the case source files and replaced the public folder with public(from working image) and made a patch file from it and applied the patch the built the kernel and flashing was done but wifi is not available or there is issue with the wifi that is mentioned above while checking the dmesg it shows btintel: exports duplicate symbol btinte_check_bdaddr (owned by kernel)

Hi, Your issue just indicates that you only update the kernel modules but not also the kernel image itself… exports duplicate symbol means part of the symbols are in the modules and same symbol was in the kernel image too. Do you really know what is the difference between kernel modules and images?

so how can i make this upgrade? or is there any way to solve this issue

Do you really know what is the difference between kernel modules and image? Could you answer this question first? It is okay to just tell you don’t know. I need to know for what knowledge you have on your side for next guidance… It is not helpful if you just keep repeating same things again and again.

Kernel driver could be built for 2 types. Kernel image → file is under /boot/Image on Jetson. (when you set =y in kernel config, it will be here) Kernel modules (ko files) → files are under /lib/modules/ (when you set =m in kernel config, it will be here) These two files need to updated at same time and based on same version. For example, you cannot use a ko file based on kernel 6.7 to Jetson because the kernel version we provided in kernel 5.10. Your issue so far is you only have ko files put into device and tried to run, but you never upgrade the /boot/Image . We have document here to guide how to build kernel from NVIDIA kernel sources. https://docs.nvidia.com/jetson/archives/r35.5.0/DeveloperGuide/SD/Kernel/KernelCustomization.html#building-the-kernel

I have followed these same steps at which point does this issue occour my uname -r gives 5.10.104-tegra
