am3352 emmc在uboot下无法识别

我们3352的板子

mmc0接emmc 4g (兼容4.5.1协议)

mmc1接sd卡

现在的情况是:

通过sd卡可以正常启动,进入linux后可识别emmc并能对其进行格式化,读写操作。

但是在uboot下,如果使用命令mmc dwv 1切换到emmc,则导致uboot复位:

=> mmc dev 1

date  abort

pc:〔bff72104〕lr:〔bff720f9〕

……

flags:nzcv irqs off  fiqs on mode svc-32

resetting cpu......

请大家帮忙分析下原因,谢谢了,顺祝大家端午快乐!
