>> Thanks, the missing clock-frequency was part of my problem. The rest was solved by adding some more quirks to the esdhc-driver (SDHCI_QUIRK_FORCE_1_BIT_DATA and >SDHCI_QUIRK_RESET_AFTER_REQUEST). Why it is necessary to force 1-bit data transfers I am a bit unsure about, since the mpc8308 reference manual clearly states that 4-bit >transfers are supported.

SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12 worked (with my other quirks disabled), thanks!
