cannot mount some sdcard after boot

we're using zu4cg board for development.  Usually we use Kingston 8GB sd card, it works well.  After boot linux, we can mount sdcard using command: mount /dev/mmcblk0p1 /mnt

But for some other brand sd card, boot is okay, but we cannot find /dev/mmcblk0p1, so cannot mount sdcard.

Could anyone help us? Below listed some logs, Thanks!
