IW612 (WiFi) not working on i.MX93EVK #1837

Open andreluizeng opened 1 month ago

andreluizeng commented 1 month ago

Hello !

I am trying to test the WiFi module (IW612) available on i.MX93EVK and it fails when loading the moal module. The Issue is detected on both Nanbield and Scarthgap releases.

Steps to reproduce:

1 - Edit/create the wpa_supplicant.conf fiile with the following information:

      ctrl_interface=/var/run/wpa_supplicant
      ctrl_interface_group=0
      update_config=1

      network={
             ssid="SSID"
             scan_ssid=1
             psk="password"
             #proto=RSN
             proto=WPA2
             key_mgmt=WPA-PSK
             pairwise=CCMP
             group=CCMP
      }

2 - Probe the mlan and moal modules:

            # modprobe mlan
            # modprobe moal mod_para=nxp/wifi_mod_para.conf

3 - Configure the mlan0:

            # wpa_supplicant -d -B -i mlan0 -c wpa_supplicant.conf -Dnl80211 & 
            # udhcpc -i mlan0

Below the logs of a test performed on the master branch:

            root@imx93-11x11-lpddr4x-evk:~# uname -a

At this point the mlan0 is not available.

I appreciate any help.

I have the same issue in the 6.6.3-6.6.3-1.0.0-6.6.3-1.0.0-gc5bdfbdac605 Scarthgap version.
