IMX6ul boot fail: kernel panic -- not syncing

[zhanglutong]

Hi Everyone,

I am struggling with this problem:

• platform:

imx6ul boots from mmc controlled SD card.

• Problem:

Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

• booting process

• u-boot

The uboot, zImage, dtb and rootfs are built from a yocto distribution.

Can anyone help? Thanks

I just had exactly the same kernel panic on an iMX6ULL. The cause for me was accidentally flashing the wrong DTB. I'd used the imx6ul version instead of the imx6ull version.

Hello Lutong,

Usually kernel panic is caused by memory errors so one can recheck it

with memory test
