SDIO SUPPORT on IMX8MM MINI LPD4-CPU2

[vinayharitsakp1]

Team,

I am trying to connect uSD Adapter Fixed 3.3 V rev A board to micro SD slot of IMX8MM MINI LPD4-CPU2. on the muratha board i am connecting CYW54591.

Following are the DTS changes i am doing

&usdhc2{

compatible = "fsl,imx6q-usdhc";
reg = <0x02194000 0x4000>;
interrupts = <0 23 0x04>;
clocks = <&clks 164>, <&clks 164>, <&clks 164>;
clock-names = "ipg", "ahb", "per";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc2_1>;
cd-gpios = <&gpio2 2 0>;
wp-gpios = <&gpio2 3 0>;
bus-width = <8>;
no-1-8-v;
non-removable;
mmc-pwrseq = <&usdhc2_pwrseq>;
pm-ignore-notify;
cap-power-off-card;
// keep-power-in-suspend;
enable-sdio-wakeup;
mmc-hs200-1_8v;
mmc-hs400-1_8v;
bus-width = <8>;
status = "okay";

brcmf: bcrmf@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";
};
};

I am getting the following error message:

Request you to guide me if the MicroSD slot on Imx8mm mini  evk board supports sdmmc/ reconfiguration of SDIO.

Team,

Do We have any update on the ticket? 

@sdio, imx8m mini, cyw4373, wifi, bt

[vinayharitsakp1]

Team, Please clarify the same. A faster resolution of the ticket would help me.

I am using I. MX 8M MINI : 8MMINILPD4-CPU2 :: 8MM MINI :BB Board.

The version of Board i can see behind the board i am using  is SCH-31407 REV C4 and bar code number TR21250978.

Can we connect murata uSD-M.2 to SD card slot of iMX8M Mini EVK Board?

Will usdhc2 work on this SD card slot on iMX8MM mini?

if usdhc2 works on SD card slot on the above mentioned board then .please suggest the changes i need to incorporate.

The uSDHC1 and uSDHC2 of EVK board is connected to WIFI and MicrosSD card
slot respectively. So just use the uSDHC1 for wifi, uSDHC2 is used for SD CARD.

For the i.MX8MM evk BOARD are you using the old version or newest version Board?
