Hello qingzong,

Try removing the pfuze100 from the kernel, and see that it can be boot up

Regards

If you don't have PMIC you can't use the external reset.

In this case keep wdog1 enabled and wdog2 disabled, which is the default configuration for imx6qdl.dtsi:

imx6qdl.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

This is overriden in SABRE SD EVK dts:

imx6qdl-sabresd.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

so you need to make sure wdog1 and wdog2 configuration from imx6qdl.dtsi is not overridden somewhere in your board dts hierarchy.
