TI中文支持网你好：
我在设置了BOOTCMD。我的ENVE的参数是
bootdelay=3
baudrate=115200
autoload=no
verify=yes
bootfile=uImage
ramdisk_file=ramdisk.gz
loadaddr=0x81000000
script_addr=0x80900000
loadbootscript=fatload mmc 0 ${script_addr} boot.scr
loaduimage=fatload mmc 0 ${loadaddr} uImage
bootscript= echo Running bootscript from MMC/SD to set the ENV…; source ${script_addr}
nandboot=echo Booting from nand …; nandecc hw 0;run nandargs; nand read ${loadaddr} 280000 440000; bootm ${loadaddr}

然后我用SD卡启动出现

DRAM: 2 GiB
MMC: OMAP SD/MMC: 0

接着一直打印

很长一段后直接进入U-BOOT命令行，不可以加载内核和文件系统这个问题怎么解决，谢谢。我用的是EZSDK的代码。

我已经解决了，是bootcmd弄错了。
bing zhang6：
已经解决
