When initialising mmc with old atmel_mci driver I get this: ---8<--- U-Boot> mmc init Manufacturer ID: 03 OEM/Application ID: 5344 Product name: SD128 Product Revision: 5.8 Product Serial Number: 8227719 Manufacturing Date: 06/03 SD Card detected (RCA 58916) CSD data: 00260032 1f5983c0 fefa4fff 924040ab CSD structure version: 1.0 MMC System Spec version: 0 Card command classes: 1f5 Read block length: 512 Supports partial reads Write block length: 512 Does not support partial writes Supports group WP: 32 Card capacity: 125960192 bytes File format: 0/0 Write protection: mmc: Using 131072 cycles data timeout (DTOR=0x62) .mmc1 is available --->8--- best regards Andreas Bie?mann
