I have a problem with activation of WiFi module(AP6212) in my MYiR MYD-Y6ULL custom board. The problem is come up with Linux v4 , it is working(wlan0 can be seen) on Linux v5.
This is my content of related "usdhc2" configuration on the DTS file;
&usdhc2 {
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc2_alt &pinctrl_wifi>;
bus-width = <4>;
no-1-8-v; // force 3.3V VIO
non-removable;
cd-post;
pm-ignore-notify;
wifi-host; // pull in card detect mechanism for BCMDHD driver
status = "okay";
brcmf: bcrmf@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";
};
};

This is the output message from dmesg.
Solved! Go to Solution.
It seems there is a file which is AP6212 related brcm43430-sdio.txt and bin files for the L4.1. We got it from AMPAK, problem solved. Thank you for the reply.

It seems there is an incompatibility with brcm sdio files(e.g. brcm43430-sdio.bin , brcm43430a0-sdio.bin , brcm43430-sdio.txt etc.), Is there any Linux v4.x version files for this sdio files?

This is the kernel module output for brcmfmac.ko.
Hello,
The logs looks correct so I cannot say for sure what could be wrong. Also, I would suggest to contact your module vendor (broadcom) for further assistance on this.
Best regards,
Aldo.
Thank you for your reply.
It works on v5 Linux so Broadcom couldnt help about the problem. Is there any example documents or DTS file content which works on v4 Linux for this module?
Kindly regards.
