====Setup for DHCP connection====
 +
 
 +
Add the network configuration for <code>systemd-networkd</code>, disable the <code>connman</code> service and enable the <code>resolv.conf</code> via <code>systemd-resolved</code>:
 +
 
 +
<pre class="workstation-terminal">
 +
root@desk-mx8mp:~# cat /etc/systemd/network/21-wlan0.network
 +
[Match]
 +
Name=wlan0
 +
 
 +
# Prevent the interface loading if the kernel boots from nfs
 +
KernelCommandLine=!nfsroot
 +
 
 +
[Network]
 +
DHCP=yes
 +
root@desk-mx8mp:~# systemctl disable connman.service
 +
Removed /etc/systemd/system/multi-user.target.wants/connman.service.
 
...
 
...
 
...
 
...
 +
root@desk-mx8mp:~# ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
 +
</pre>
 +
 +
Setup your <code>wpa_supplicant.conf</code> configuration file for handle WiFi connection:
 +
 +
<pre class="workstation-terminal">
 +
root@desk-mx8mp:~# cat /etc/wpa_supplicant.conf
 +
ctrl_interface=/var/run/wpa_supplicant
 +
ctrl_interface_group=0
 +
update_config=1
 +
 +
network={
 +
        ssid="daveguest"
 +
        psk="********"
 +
}
 +
</pre>
 +
 +
Reboot the system and manually start the <code>wpa_supplicant</code> using the <code>wlan0</code> interface and the <code>wpa_supplicant.conf</code> configuration file:
 +
 +
<pre class="workstation-terminal">
 +
root@desk-mx8mp:~# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
 +

DESK-MX8M-L-4.1.0 release
2024/05/31 DESK-MX8M-L-4.x.x configuration for SBC ORCA


Peripheral WiFi[edit | edit source]

Device tree configuration[edit | edit source]

ORCA SOM[edit | edit source]

Here below an example of device tree configuration used on standard DAVE's kit for the ORCA SOM:

From imx8mp-mito8mplus-cb1001.dts: 

/* DWS */
&usdhc1 {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_usdhc1>;
	vmmc-supply = <&reg_wlan_en>;
	bus-width = <4>;
	non-removable;
	status = "okay";
};

and from imx8mp-mito8mplus.dtsi: 

	pinctrl_usdhc1: usdhc1grp {
		fsl,pins = <
			MX8MP_IOMUXC_SD1_CLK__USDHC1_CLK	0x190
			MX8MP_IOMUXC_SD1_CMD__USDHC1_CMD	0x1d0
			MX8MP_IOMUXC_SD1_DATA0__USDHC1_DATA0	0x1d0
			MX8MP_IOMUXC_SD1_DATA1__USDHC1_DATA1	0x1d0
			MX8MP_IOMUXC_SD1_DATA2__USDHC1_DATA2	0x1d0
			MX8MP_IOMUXC_SD1_DATA3__USDHC1_DATA3	0x1d0
		>;

Setup for DHCP connection[edit | edit source]

Add the network configuration for systemd-networkd, disable the connman service and enable the resolv.conf via systemd-resolved: 

root@desk-mx8mp:~# cat /etc/systemd/network/21-wlan0.network
[Match]
Name=wlan0

# Prevent the interface loading if the kernel boots from nfs
KernelCommandLine=!nfsroot

[Network]
DHCP=yes
root@desk-mx8mp:~# systemctl disable connman.service
Removed /etc/systemd/system/multi-user.target.wants/connman.service.
...
...
root@desk-mx8mp:~# ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Setup your wpa_supplicant.conf configuration file for handle WiFi connection: 

root@desk-mx8mp:~# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
        ssid="daveguest"
        psk="********"
}

Reboot the system and manually start the wpa_supplicant using the wlan0 interface and the wpa_supplicant.conf configuration file: 

root@desk-mx8mp:~# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
Successfully initialized wpa_supplicant
root@desk-mx8mp:~# [  132.978188] DEBUGFS PEER MAC = 0xd0:0x21:0xf9:0x35:0x8e:0x88
[  133.070518] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

root@desk-mx8mp:~#

Then the interface will be properly configured (see the IP address configured) and the network access is enabled: 

root@desk-mx8mp:~# ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

Setup for static connection[edit | edit source]

Check that the interface is properly intialized: 

root@desk-mx8mm:~# ifconfig mlan0
mlan0: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether e8:fb:1c:e1:80:65  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Setup the wpa_supplicant.conf configuration file for handling the WiFi connection, for example: 

root@desk-mx8mm:~# cat /etc/wpa_supplicant.conf
network={
    ssid="ZyXEL"
    key_mgmt=NONE
}

Apply the wpa_supplicant.conf configuration file manually starting the wpa_supplicant: 

root@desk-mx8mm:~# wpa_supplicant -i mlan0 -c /etc/wpa_supplicant.conf -B
Successfully initialized wpa_supplicant
...
root@desk-mx8mm:~#

Add the mlan0 IP address: 

root@desk-mx8mm:~# ip addr add 192.168.11.165/255.255.255.0 dev mlan0

Then the network access is enabled:
