Wi-Fi Bluetooth for Linux

I'm trying to test cypress-fmac-v5.10.9-2021_1020.zip in my environment (imx6sx-sdb/SDIO Adapter CYW9SDIOAD/WiFi module CYW43455).
When linux v5.10.9, usdhc3 (mmc2) of imx6sx-sdb does not recognize SDIO.
If SD card, it is recognized .

If linux v5.4.x, the below boot message is displayed at the boot time without any problem, and it connects to WiFi module normally.
    mmc2: new high speed SDIO card at address 0001

Somebody help me?

Hi @YuKi_3194086 ,

Let me check for the issue

In the FMAC driver pacakge, there are dtb files available for imx6sx in cypress-devicetree\iMX6SX\4.9.88 folder. Are you using the same dtb files?

Also, is this Murata 1MW 43455 module that you are using?

Thanks

Hello @raks_99 

Thank you so much for your reply.

I don't use the dtb files of cypress-devicetree\iMX6SX\4.9.8\ forder.
The reason is that using it causes Linux boot to stop in the middle.

Instead, I'm using a dtb file built with linux v5.10.9 using the below command.
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx6sx-sdb-btwifi-fmac.dts

Yes.

Thank you.
