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.
