mini6410 在linux下tftp system.img速度感觉好慢，就想把fat 命令支持起来，这样子，system.img存到sd卡上就可以fatload到RAM里。友善的什么superboot可能用的就是fatload之类命令支持的。 eg. fatls mmc 0 fatload mmc 0 50008000 system.img 共4个文件涉及了修改 include/configs/mini6410.h cpu/s3c64xx/hs_mmc.c common/main.c cpu/s3c64xx/movi.c 其中cpu/s3c64xx/hs_mmc.c是从uboot1.3.4 copy过来做了点修改。 common/main.c是删除了FriendlyArm Menu, 这menu没用 帖出./include/configs/mini6410.h patch，其他patch大家下载吧 --- ../aaa/u-boot-mini6410/include/configs/mini6410.h    2010-06-22 18:26:23.000000000 +0800 +++ ./include/configs/mini6410.h    2010-08-17 21:52:46.000000000 +0800 @@ -148,7 +148,8 @@                          CFG_CMD_ENV     | \                          CFG_CMD_NAND    | \              CFG_CMD_PING    | \ -                        CFG_CMD_MOVINAND) \ +                        CFG_CMD_MOVINAND| \ +                        CFG_CMD_FAT) \                          & ~(CFG_CMD_AUTOSCRIPT  | \                                  CFG_CMD_BOOTD   | \                                  CFG_CMD_IMI     | \ @@ -167,7 +168,7 @@ #define CONFIG_ETHADDR        08:90:90:90:90:90 #define CONFIG_NETMASK          255.255.255.0 #define CONFIG_IPADDR        192.168.1.230 -#define CONFIG_SERVERIP        192.168.1.88 +#define CONFIG_SERVERIP        192.168.1.10 #define CONFIG_GATEWAYIP    192.168.1.1 #if defined(FRIENDLYARM_BOOT_ANDROID) @@ -415,6 +416,8 @@ #define    CONFIG_NAND #define CONFIG_MOVINAND +#define    CONFIG_MMC 1 + //#define CONFIG_NAND_BL1_8BIT_ECC /* Settings as above boot configuration */
