SD card mount error on imx6dl with the BSP(4.1.15_2.0.0)!

[zhanghaijian]

Hi,all

There is an emmc and a SD card on my own borad,the emmc is accessed through SDHC4,the SD card is accessde through SDHC3.Do not insert the SD card ,auto reboot the board every 20 mimutes. The device node /dev/mmcblk2p1 appear under /dev sometimes.I mount /dev/mmcblk2p1 to /meida/mountpoint,It is strange that  the contents of /dev/mmcblk2p1 is same as /dev/mmcblk3p1.The same files are zImage and imx6dl-sabresd.dtb.

Hi zhang

one can check sd3_cd signal, if it is floating. Also may be useful to rebuild images

anew from scratch. Use nxp software described on
