Hello, Thanks a lot for your post. Could you please let me know what configurations are to be added to /include/configs/board.h file to enable MMC/SD support. I've added the following configurations /* MMC/SD Support */ /* To include File system support for MMC */ #define CONFIG_DOS_PARTITION #define CONFIG_CMD_EXT2 #define CONFIG_CMD_FAT #define CONFIG_MMC #define CONFIG_GENERIC_MMC #define CONFIG_DAVINCI_MMC #define CONFIG_CMD_MM /* To enable Environment variables to reside on MMC. */ #define CONFIG_DOS_PARTITION 1 //#undef CONFIG_MMC #define CONFIG_SYS_MMC_BASE 0xFFFB4000 #define CONFIG_SYS_MMC_BLOCKSIZE 512 and when I enter mmcinit, u-boot says command not found. Please find the logs: and thanks alot for your time :) Electrum> mmcElectrum> mmc Usage: MMC sub system Electrum> mmcinit Unknown command 'mmcinit' - try 'help' Electrum> mmcinfo MMC Device 0 not found Thanks, Kalyan. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
