iMX53 Watchdog Configuration for Mfg Tool

[bdp42]

The "iMX Manufacturing Tool Custumization Guide" states that we need to disable the watchdog in iMX53 TO2 device when building the (mfg mode) Linux kernel. I've done this in the kernel config by unsetting CONFIG_WATCHDOG

However I get the following when I run the manufacturing tool

cpu_id is 53

The watchdog is not configured, needed by mx35/mx51/mx53

705, No such file or directory

Is this the expected behaviour or has this been done incorrectly?

Thanks,

Bruno

Hi Bruno

meaning "disable the watchdog" is using boot fuse WDOG_ENABLE.

Once enabled, watchdog can not be disabled, only serviced.

Also one can try to check option under

Device Drivers > Watchdog Timer Support > MXC watchdog.

• CONFIG_MXC_WATCHDOG—Enables Watchdog timer module.

Best regards
