After that, i used the folled code:

sudo dmesg |grep iwlwifi

and the termial shows:


and meanwhile the setting finally has wifi option, but no adapter found.

It’s wired, when i used the primary kernel, the wifi works normal. But it failed for RT-kernel. could you help me to fix it?

Hi,
We support jetson_multimedia_api and gstreamer. Please make sure you have checked the document:
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/Multimedia.html
https://docs.nvidia.com/jetson/archives/r36.3/ApiReference/index.html
There are some examples in

Q: Is there any example of running RTSP streaming?
Q: Is there an example for running UDP streaming?
Q: I have a USB camera. How can I launch it on AGX Orin?

For further issues, please share a method to replicate the issue through gstreamer command, or either sample. We will set up developer kit and check.

Thanks!

Hi,
Please enable the configs for a try:

Hello,

thanks for the link. I have noticed that they have downloaded a backport from Linux Backports. As i’m using 5.15.148-rt-tegra kernel, i choosed backports-5.15.148-1.tar.xz. then i uesd these code from this link:

tar Jxfv backports-5.15.148-1.tar.xz.
cd backports-5.15.148-1
make defconfig-iwlwifi
make -j8
sudo make install


and

I add the following line to /etc/modprobe.d/iwlwifi.conf

options iwlwifi 11n_disable=1

and , reboot OS.
But the wifi option still doesn’t appear.

By a way, when i input: lspci, there is

0004:01:00.0 Non-Volatile memory controller: Silicon Motion, Inc. SM2263EN/SM2263XT SSD Controller (rev 03)

Does it means that the network card hardware is recognized by the system, but the driver may not be loaded or configured correctly?

Thanks!

Hi,
We follow the steps to build/flash RT kernel to AGX Orin devkit and WIFI module works fine:
