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 = <®_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

Setup for static connection[edit | edit source]
Check that the interface is properly intialized:
root@desk-mx8mm:~# ifconfig mlan0

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:
