How can I stop enabling the i.MX6Q watchdog?

Hi,

I understood there is no way to clear the Watchdog Enable (WDE) bit of the Watchdog Control Register (WCR) in software once it is set.

So I would like to keep WDE bit clear from the beginning to the end.

Fortunately ROM and uboot seems do nothing.

Is there any way to ignore the watchdog during linux configuration?

It is nice to switch with setenv kernel variable or dts binding description without rebuild images.

Can anyone help me?

one can check sect.2.11.7 Menu Configuration Options attached Linux Manual.

>It is nice to switch with setenv kernel variable or dts binding description without rebuild images.

in dts wdog can be configured with status = "okay"; or "disabled" :

linux/arch/arm/boot/dts/imx6qdl-sabresd.dtsi

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

Best regards
