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?
Could you please give the patches from Peter Vollmer a try:

Thanks, Stefan
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@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.
