Cross compile of rtl8852au driver for jetson nano
In this page, I’ll introduce how to cross compile of rtl8852au driver for jetson nano.
host computer：
Ubuntu 18.04 LTS
・Jetpack installed ・Kernel cross-compiled
target board：
Jetson nano
procedure for cross compile：
git clone http://github.com/lwfinger/rtl8852au.gitGet driver source codes.
cd rtl8852au/platform/
vi jetson_nano.mkSwitch directory and make new “.mk” file to compile for jetson nano.

makeStart compilation.
Install driver
Finishing compilation, wlan.ko is generated.
Transfer wlan.ko to jetson nano with SCP or TFTP.
We can find WI-U3-1200AX2 as USB device on jetson nano.
Install wireless driver.
sudo insmod wlan.kowlan0 is generated.
