Hi, How are you? I've compiled a linux OS using yocto project. I want to have wifi interface using WM-N-BM-02SDIO . I have set the WM-N-BM-02SDIO on sdio-1 which is considered for sd card. I have successfully added wifi before in a project with kernel 4.x.x. now I'm trying with new sdk: uname -a 5.4.3-g9c2490ac8-dirty #3 SMP PREEMPT Sun Aug 8 12:11:16 UTC 2021 armv7l GNU/Linux I have an issue with the brcmfmac kernel module. I have enabled brcmfmac debug and enabled all message types in debug messages. you can see the dmesg output when I put this command insmod /<path to ko file>/brcmfmac.ko debug=0x1FFFE : [ 2526.159218] brcmfmac: brcmfmac_module_init No platform data available.

The vendor and device id are correct so can you retry using debug=0x31416 enabling SDIO debug level.
