The SDK DTS [1] also includes mmc1_cd_cfg in both pinctrl states, with a pull-up and 3.3 V configuration. Neither mmc1_cfg nor mmc1_uhs_cfg covers this pin. Is that configuration unnecessary on this board? > + no-mmc; > + no-sdio; > + disable-wp; > + cap-sd-highspeed; > + vmmc-supply =3D <&aldo4>; > + vqmmc-supply =3D <&aldo1>; Could you confirm which rail supplies the card's VDD? The SDK DTS [1] uses p3v3 for vmmc rather than aldo4. Does that RPMI regulator map to ALDO4, or is the card powered by a different rail?
