USB WIFI - Rafcin/XavierToolkit GitHub Wiki

By default USB-WIFI dongles do not work on the Jetson Xavier. How I fixed it was this way, and I use a Penguin Wireless N USB Adapter for GNU / Linux (TPE-N150USB) from https://www.thinkpenguin.com/gnu-linux/penguin-wireless-n-usb-adapter-gnu-linux-tpe-n150usb but you can use any usb that you can support the drivers for, in this case the penguin uses Atheros ath9k_htc drivers but something like a TP-Link Wifi dongle uses Realtek.

Before you continue, note that you should source /build/envsetup.sh before you start, and then the env script when you run it will also source the other .sh files in build.

Steps:

  1. Install Jetpack

  2. Flash Jetson and if you want do the rest of the setup and install Cuda and everything else.

  3. Confirm Jetson is working and stable.

  4. On the Host PC install https://github.com/jtagxhub/jetpack-agx-build and follow the instructions on his page. (Clone the repo as it says by the name 'build', and clone it inside the Jetpack folder, that jt folder is reffered to as $TOP)

  5. Follow step 3.1 to 3.10 as they say. (You don't need to flash, and your kernel might give you a build error)

  6. Once you do that and you have reflashed your system and make sure it works, open the kconfigmenu and do the following... Under Networking --> Wireless, enable everything for cfg80211, this is an important step, you can not compile the kernel without it. Make sure you set this to Y not M. (Builds into Kernel) (This will solve the kbuild compiler errror)

  7. Under Device Drivers -> Networking -Wireless Lan, install the important driver you need, do note that when you install it, do not set it as a module but instead of M use Y. (Builds into Kernel)

  8. Save the config and exit.

  9. Run the kbuild command and wait for the kernel to complete, it will say done when it is finished. it should look like...

kernel install...
cp /home/raf/Downloads/out/KERNEL/arch/arm64/boot/Image /home/raf/Downloads/Xavier/Linux_for_Tegra/kernel/
cp /home/raf/Downloads/out/KERNEL/arch/arm64/boot/dts ...
...
Done
  1. After that simply run flash_kernel, make sure your Jetson is in bootloader mode and you are done. When it is flashing you should see this:
flash_kernel 
sudo ./flash.sh -k kernel jetson-xavier mmcblk0p1

As a final check, run sudo nmcli and it will display the driver no longer as USB0 but as wlan0.
