sd-card is not working on espressobin

[Moritz Berghof]

Hi Community,

Hi Marek, Hi Stefan,

we are still working on the u-boot master of the espressobin platform.

Do you have any ideas why mmc cannot find any sd-card?


The mmc devices can be list and I changed the armada-3720-espressobin.dts<https://pxccs-gitlab.dev.de.innominate.com/pxccs-components/u-boot-mainline/-/blob/master/arch/arm/dts/armada-3720-espressobin.dts> with:


vcc_sd_reg0: regulator at 0 {

        ...

};


&sdhci0 {
        pinctrl-names = "default";
        pinctrl-0 = <&sdio_pins>;
        bus-width = <4>;
        vqmmc-supply = <&vcc_sd_reg0>;
        status = "okay";
};


MMC ist activated on mvebu_espressobin-88f3720_defconfig<https://pxccs-gitlab.dev.de.innominate.com/pxccs-components/u-boot-mainline/-/blob/master/configs/mvebu_espressobin-88f3720_defconfig>.
