Your rootfs binary is EXT2 while the kernel mounts VFAT as root. This suggests that your SD card was

improperly prepared for booting or your kernel parameter string has a invalid "root=<dev>" token.

Make sure you followed either Section 7.4 or Section 8.4 of i.MX 6Solo/6DualLite SABRE-AI Linux

User's Guide for your BSP version to prepare your SD card. Make sure you specified the correct

boot partition on the kernel command line. See Section 9.2 of the same document for additional

details. Document bundle for your BSP version can be obtained from this page:

Embedded Linux for i.MX Applications Processo|NXP

Have a great day,

thank you very much， bpe！

The "kernel panic" reason is  that i divided sd card into two partitions：ext3 and fat,  so kernel maybe mount vfat partition, but the menu bar shows“口口口”，i don`t know why？ i am doing the new rootfs

I plan  to flash u-boot.bin to spi nor flash,  flash uImage and rootfs  to emmc through sd card，how to partition emmc,and flash,could you give me some suggests？
