WIFI doesn't work in image create by 'create-jetson-nano-sd-card-image.sh'

Hello, I have trouble with the image created by ‘create-jetson-nano-sd-card-image.sh’.

I followed the steps in the link below to create a system image,
then I get a image successfully and WIFI ssid can be found correctly.
(PREEMPT-RT patches for Jetson Nano)

But when I try to connect WIFI, the USB wireless network adapter(TP-Link TL-WN725N 2.0)
disconnect from jetson nano and it get no response(wireless keyboard & mouse disconnect too).
Replug just doesn’t work.

By the way, the wireless network adapter runs well
in the system installed with ‘jetson-nano-sd-r32.1-2019-03-18.img’,
download from
(https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#write”).

Any suggestion will help, thanks a lot!

Hi 245947502

I think there is a mismatch with your kernel version. You can check with ‘uname -a’ to get the version of the kernel you have build. Compared with the offcial one.

Firmware and modules work with the kernel with the same signature - the version number of the kernel here.

I have checked this before, I remember the kernel and modules both were 4.9.140-rts***.
Both kernel and modules are created by official course.https://forums.developer.nvidia.com/uploads/short-url/7TBU5Ld9C3MU0bU0TDRG96lRnSC.pdf

Could you try without change the kernel version?
export LOCALVERSION=-tegra
, for details https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide%2Fkernel_custom.html%23
The default kernel version is 4.9.140-tegra.

This may help, I will try it now. THX!
