WiFi not working with Ubuntu 20.04 image on STM32MP157F-DK2

[haimiko]

Interestingly enough the wifi device isn't showing up on the STM32MP157F-DK2, with the Ubuntu20.04 release, even though it's the same chip as on the STM32MP157C-DK2. I tried running the activate_wifi.sh script but still no joy.
dmesg error shows the following:

[ 24.500978] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.st,stm32mp157c-dk2.bin failed with error -2 Looks like the bluetooth firmware file and wifi cyfmac43430-sdio.bin file was missing from the release and placing it the lib/firmware/brcm folder didn't help.

with Firmware copied now the dmesg reads as follows:

wget -c https://raw.githubusercontent.com/STMicroelectronics/meta-st-stm32mp/dunfell/recipes-kernel/linux-firmware/linux-firmware/brcmfmac43430-sdio.txt wget -c https://github.com/murata-wireless/cyw-fmac-fw/raw/master/cyfmac43430-sdio.bin wget -c https://github.com/murata-wireless/cyw-fmac-fw/raw/master/cyfmac43430-sdio.1DX.clm_blob

sudo mkdir -p /mnt/rootfs/lib/firmware/brcm/

sudo cp -v ./brcmfmac43430* /mnt/rootfs/lib/firmware/brcm/ sudo cp -v ./brcmfmac43430-sdio.txt /mnt/rootfs/lib/firmware/brcm/brcmfmac43430-sdio.st,stm32mp157c-dk2.txt

UPD: And recheck file in your board brcmfmac43430-sdio.st,stm32mp157c-dk2.txt in folder /lib/firmware/brcm/

I made big changes in the project, see develop branch Now the Linux kernel from the official ST repository with fresh updates and fixes: 5.10.61, latest u-boot and secure trust zone And finally, the cherry on the cake - Ubuntu 22.04 Te
