Hi,

a  uboot-imx/include/configs/mx6sabresd.h file:

#define CONFIG_SYS_FSL_USDHC_NUM    3

#define CONFIG_SYS_MMC_ENV_DEV      1   /* SDHC3 */

#define CONFIG_SYS_MMC_ENV_PART                0       /* user partition */

 

uboot log:

U-Boot 2015.04-14468-g19b5506-dirty (Apr 17 2016 - 21:32:07)

MMC:   FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2

MMC Device -1 not found

No MMC card found

 

what's wrong with it?

 

有人可以帮我看看这时什么原因吗?

我该怎么找问题的原因,希望大家帮我看看。

我的板子上flash 有32G,用了sd1和sd3两个控制器,在u-boot-2009.08上运行是可以的,现在想移植u-boot-2015.04,就碰到了这个问题,我已经被这个问题困扰了一个星期了,希望大家帮我看看,谢谢了。
