Laird Radio Implementation

MichaelBMiner — Wed, 03 Jan 2024 18:55:00 GMT

I am trying to implement a LairdCP LWB5+ radio module. A year ago this was working on our platform, since then Laird has made changes in their github repo. I have renamed all of my includes to match their new names but I am not able to build.

In my local.conf I have

PREFERRED_PROVIDER_wpa-supplicant = "summit-supplicant" PREFERRED_PROVIDER_wpa-supplicant-cli = "summit-supplicant" PREFERRED_PROVIDER_wpa-supplicant-passphrase = "summit-supplicant" PREFERRED_RPROVIDER_wireless-regdb-static = "wireless-regdb" LWB_REGDOMAIN = "US"

In my mainapplication.inc I have

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

I am attempting to use https://github.com/LairdCP/meta-summit-radio/tree/lrd-10.0.0.x as this is what we have been using since this project was first created.

When I do my bitbake I get the error

ERROR: kernel-module-lwb5p-backports-summit-10.54.0.13-r0 do_compile: oe_runmake failed

I can confirm that I have disabled bluetooth and cfg80211 and mac80211, I believe I have added all the required dependencies. Just wondering if anyone has encountered this.

That kind of error happens when kernel was restored from sstate cache without build

bitbake -c cleansstate linux-imx

should fix it, if not dump yocto build completely with sstate cache and build again
