SD卡启动后报错如下  ，而用mfgtools烧emmc启动是ok的，

另外我安装  我按照  Running the Image from MMC/SD 中方法，设置uboot,最后提示内核format 格式问题如下:
setenv loadaddr 0x12000000
setenv fdt_addr 0x18000000
setenv fdt_high 0xffffffff
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk0p2 rootwait rw video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 1;mmc read ${loadaddr} 0x800 0x2000;mmc read ${fdt_addr} 0x5000 0x800;bootm ${loadaddr} - ${fdt_addr}'

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 1;mmc read ${loadaddr} 0x800 0x2000;mmc read ${fdt_addr} 0x5000 0x800;bootm ${loadaddr} - ${fdt_addr}'

setenv bootcmd 'run bootcmd_mmc'

saveenv

=> run bootcmd

MMC read: dev # 1, block # 20480, count 2048 ... 2048 blocks read: OK
Wrong Image Format for bootm command
ERROR: can't get kernel image!

请问如何解决呢，多谢
