Installing the new release (Ubuntu 22.04) was detected some NXP boards as iMX8MNEVK, iMX8MM-EVK, iMX8MP-EVK and iMX8ULP-EVK had an issue with the WIFI
module that basically it does not initialize at boot.
Remember, the supported WIFI modules in Ubuntu 22.04 in the EVKs are the following:
• NXP 88W8987
• NXP 88W9098
• NXP 88W8997
• NXP IW416
• NXP 88W8801
• NXP IW612
To initialize the WIFI module of NXP EVKs in Ubuntu 22.04 you can set the following
command in console:
sudo modprobe moal mod_para=nxp/wifi_mod_para.conf
That command find the correct driver for our WIFI module and then initialize it, but this
only works when Ubuntu is working and if you reset the EVK you need to set the command
again.
The definitive solution is create a custom startup script as a service:
Step 1: Go to etc/systemd/system
cd etc/systemd/system
Step 2: In this directory create a new file with the name of your preference but the
extension must be .service.
You can do it with nano or vim:
sudo nano
or
sudo vim
The file must contain:
[Unit]
Description=”Wifi Start”
[Service]
ExecStart=sudo modprobe moal mod_para=nxp/wifi_mod_para.conf
[Install]
WantedBy=multi-user.target
Now save the file, in my case the name was wifi_start.service.
Step 3: Now we need to enable the script in the startup/boot sequence following the
command:
sudo systemctl enable wifi_start.service
Remember in wifi_start.service is the name as you saved your file.
Finally, each time you boot your board, the WIFI module will initialize automatically.
