WIfi/Bluetooth not working on clean demo Yocto image iMX8Mplus

dvega — Thu, 22 Feb 2024 01:19:02 GMT

I been having issues building a Yocto image with working wifi and bluetooth. I followed the instructions on the pdf tutorial

Clone the repo and sync:

$ repo init -u https://github.com/nxp-imx/imx-manifest -b imx-linux-mickledore -m imx-6.1.36-2.1.0.xml $ repo sync

Initialize the build:

$ DISTRO="fsl-imx-wayland" MACHINE="imx8mp-lpddr4-evk" source imx-setup-release.sh -b imx-builds

Build the image (no changes where made into the local.conf file):

$ bitbake imx-image-full

This generated an image with 18 warnings that doesn't seem important, such as:

WARNING: cinematicexperience-rhi-1.0-r0 do_package_qa: QA Issue: File /usr/src/debug/cinematicexperience-rhi/1.0-r0/.rcc/qrc_cinematic-shaders.cpp in package cinematicexperience-rhi-src contains reference to TMPDIR WARNING: onnxruntime-1.16.1-r0 do_package_qa: QA Issue: File /usr/bin/onnxruntime-1.16.1/tests/onnxruntime_test_all in package onnxruntime-tests contains reference to TMPDIR [buildpaths] WARNING: qtbase-6.5.0-r0 do_package_qa: QA Issue: File /usr/lib/qtbase/ptest/tests/auto/dbus/qdbusabstractinterface/pinger_interface.h in package qtbase-ptest contains reference to TMPDIR ...

On eMMC mode. I enter the u-boot console and mounted the eMMC memory into my system

u-boot=> ums 0 mmc 2 UMS: LUN 0, dev mmc 2, hwpart 0, sector 0x0, count 0x3a68000

Once mounted it. I flashed the memory with the generated image:

$ zstdcat imx-image-full-imx8mp-lpddr4-evk.wic.zst | sudo dd of=/dev/sdc bs=1M conv=fsync status=progress 8934785024 bytes (8.9 GB, 8.3 GiB) copied, 377 s, 23.7 MB/s8938585088 bytes (8.9 GB, 8.3 GiB) copied, 377.181 s, 23.7 MB/s

Once it booted I enter the root user and tried to enable the wifi module:

After this I was expecting to see the wifi module loaded but to my surprise is not there

Why the wifi module is not there? I tried following this guide about wifi modules. The module I have is the AW-CM276MA.

I tried enabling SDIO on M.2 connector by doing:

u-boot=> setenv fdtfile imx8mq-evk-usdhc2-m2.dtb u-boot=> saveenv Saving Environment to MMC... Writing to MMC(2)... OK u-boot=> reset resetting ...

But when I do that the os doesn't boot anymore.

I checked other post such as:

I also tried downloading the official demo image from NXP Same thing happens.

Am I missing copy some file?

Do I need to enable something in Yocto?

Do I need to enable something on the kernel config?
