IMX6 Laird Support

I have been following this guide to add meta-summit-laird to my image. I am using Hardknott 3.3 and the meta-summit-laird-pre-3.4 layer. Today I finally got the radio to be recognized by the kernel and show up in ifconfig.

root@imx6ull14x14evk:~# ifconfig eth0 Link encap:Ethernet HWaddr E2:EE:EE:EE:EE:EE UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:9360 errors:0 dropped:0 overruns:0 frame:0 TX packets:9360 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:581440 (567.8 KiB) TX bytes:581440 (567.8 KiB) wlan0 Link encap:Ethernet HWaddr C0:EE:40:84:83:AA UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) root@imx6ull14x14evk:~# iw dev phy#0 Unnamed/non-netdev interface wdev 0x2 addr c2:ee:40:84:83:aa type P2P-device txpower 31.00 dBm Interface wlan0 ifindex 5 wdev 0x1 addr c0:ee:40:84:83:aa type managed channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz txpower 31.00 dBm

Now I am trying to connect to a network but I do not have wpa_supplicant or nmcli. This is a point of frustration to me.

In local.conf I have

PREFERRED_RPROVIDER_wpa-supplicant = "summit-supplicant-lwb" PREFERRED_RPROVIDER_wpa-supplicant-cli = "summit-supplicant-lwb" PREFERRED_RPROVIDER_wpa-supplicant-passphrase = "summit-supplicant-lwb" BBMASK += " \ meta-summit-radio/meta-summit-radio-pre-3.4/recipes-packages/openssl \ meta-summit-radio/meta-summit-radio-pre-3.4/recipes-packages/.*/.*openssl10.* \ " PREFERRED_RPROVIDER_wireless-regdb-static = "reg-lwb5-plus" LWB_REGDOMAIN = "US"

In my image file I have

# Install necessary libraries IMAGE_INSTALL_append = " packagegroup-core-ssh-openssh \ openssl \ can-utils \ libsocketcan \ sudo \ boost \ lumissil-kernel-module \ lumissil \ logrotate \ socat \ u-boot-fw-utils \ open-plc-utils \ dbcppp \ i2c-tools \ firmware-imx-sdma-imx6q \ iproute2 \ rng-tools \ ca-certificates \ tzdata \ alsa-utils \ htop \ ethtool \ iperf3 \ tcpdump \ iw wpa-supplicant \ libgpiod \ libgpiod-tools \ hostapd \ laird-localize-firmware \ networkinterfaces \ " # Laird Libraries IMAGE_INSTALL_append = " \ kernel-module-lwb5p-backports-summit \ lwb5plus-sdio-sa-firmware \ summit-supplicant-lwb \ summit-networkmanager-lwb \ "

When I program my board or look at the files-in-image.txt I can see -rwxr-xr-x root root 84488 ./usr/sbin/wpa_cli is installed but no other networking tools.

I know that the laird recipes remove and provide their own version of wpa_supplicant but they appear to be missing.

For more information I am using laird version lrd-11.39.0.x
