ConnMan persists your WiFi network configuration across reboots. On this Linux image, the missing piece is often that the WiFi driver module isn’t loaded automatically at boot.

In this section, you’ll run one command at boot to load the WiFi driver. After that, ConnMan should reconnect to the saved network automatically.

Confirm ConnMan can reconnect after loading the driver

First, connect to WiFi once using connmanctl (from the previous section). Then reboot the board.

After the reboot, log in and load the driver:

    

        
        
sudo /usr/sbin/modprobe moal mod_para=nxp/wifi_mod_para.conf

Give it a few seconds, then confirm you have an IP address and Internet connectivity:

    

        
        
ifconfig | grep RUNNING -A 1
curl -I http://www.example.com

If this reconnects reliably, you’re ready to automate it.

Load the WiFi driver automatically on boot

Create a small systemd unit that runs modprobe at startup.

    

        
        
sudo nano /etc/systemd/system/nxp-wifi-driver.service

Add the following:

    

        
        
[Unit]
Description=Load WiFi driver (moal) for NXP i.MX93
After=multi-user.target

[Service]
Type=oneshot
ExecStart=/usr/sbin/modprobe moal mod_para=nxp/wifi_mod_para.conf
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Enable the service:

    

        
        
sudo systemctl daemon-reload
sudo systemctl enable nxp-wifi-driver.service

Reboot and confirm the board reconnects on its own:

    

        
        
sudo reboot

After it comes back up, check WiFi and Internet:

    

        
        
ifconfig | grep RUNNING -A 1
curl -I http://www.example.com

What you’ve accomplished and what’s next:

You’ve set up an NXP FRDM i.MX 93 board as a practical Linux-based development target for ML workflows on Arm.

In this Learning Path, you:

  • Booted the board and logged in over a serial console.
  • Created a non-root user for day-to-day development.
  • Connected the board to WiFi and transferred files using SSH or USB.
  • Automated WiFi bring-up by loading the driver module on boot.

To go deeper, review the Further reading resources at the end of this Learning Path.
