Other Parts Discussed in Thread: WL1837, BEAGLEBOARD-X15
Hi sir,
we are using AM5728 reference design of custom board.
device are connected as below
MMC1 ----->SD Card
MMC2 ----->EMMC Device
MMC3 ----->WL1837 Wifi module.
I enable only two devices(mmc1,mmc2) in device tree using below method but it's now show any thing for emmc in beagle board x15 it's showing.
U-Boot Device tree:(am572x-beagle-x15-common.dts)
&mmc1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&mmc1_pins_default>;
bus-width = <4>;
cd-gpios = <&gpio6 27 GPIO_ACTIVE_LOW>; /* gpio 219 */
no-1-8-v;
};
&mmc2 {
status = "okay";
vmmc-supply = <&vdd_3v3>;
pinctrl-names = "default", "hs";
pinctrl-0 = <&mmc2_pins_default>;
pinctrl-1 = <&mmc3_pins_hs>;
bus-width = <8>;
ti,non-removable;
cap-mmc-dual-data-rate;
no-1-8-v;
max-frequency = <48000000>;
};

as per the above changes done omap_hsmmc.c file but same issue.
Any changes required in the code side, Could you give me some suggestions.
Thanking you,
