wait for root device

imx6DL/SOLO sabresd, linux-3.0.35,
用SD卡启动,卡在了
wait for root device /dev/mmcblk1p1

struct esdhc_platform_data mx6q_sabresd_sd3_data={
.always_present = 1, /加这个可以挂载文件系统,但是挂载成功后依然会出问题/
};
CD脚设置没有问题, 有人说是I2C的问题我不太清楚.. 只有求助.

楼主你好，你把的log发给我看一下，你给出这一句看不出哪里有问题。

楼主你好，你把的log发给我看一下，你给出这一句看不出哪里有问题。

log上看起来没有找到SD CARD，只找到了emmc。但是如果像设置了always_present又可以找到。只是挂在成功问题更多。如果不检测CD脚，好像也不行。

修改esdhc_readl_le中的
else if(imx_data && ESDHC_FLAG_GPIO_FOR_CD_WP) && ... )
if (boarddata && gpio_is_valid(boarddata->cd_gpio)
&& gpio_get_value(boarddata->cd_gpio))
/* no card, if a valid gpio says so... */
val &= ~SDHCI_CARD_PRESENT; 这个和下面的交换
else

val |= SDHCI_CARD_PRESENT;

然后在esdhc_writel_le中注释掉ESDHC_FLAG_GPIO_FOR_CD_WP那个if就可以挂载。但是好像出现了missing devtmpfs which is required for udev to run
我觉得这个好像已经是脚本除了问题。不知道我这样修改会不会有什么问题

CONFIG_DEVTMPFS=y is required
