Hi Stefan,

thanks for the information. I tested the patchset already, it works. The Patchset comes also from me. Peter V. and I work together on this espressobin topic.

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-ma inline/-/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.
