Hi, It seems that somewhere between v5.2 and v5.3, sdhci fails to detect SD cards on the NXP LX2160A, but continues to work with eMMC. This uses the sdhci-esdhc driver. v5.2: sdhci: Secure Digital Host Controller Interface driver sdhci: Copyright(c) Pierre Ossman sdhci-pltfm: SDHCI platform and OF driver helper mmc0: SDHCI controller
