Disabling Watchdog Timer for iMX6Q/D on uboot?

[gmmo]

I am running into an issue on a embedded system that uses JellyBeans (Linux version 3.0.35) and uses the iMX6Q/D as the main processor.

The system does not do any intense UI or graphics application (just simple UI screens), yet the WatchDog timer keeps resetting the system under some stress test we do. Somewhat after 40 hrs on, the watchdog timer resets the system.

I was told I can disable the watchdog timer on the UBoot.

Can some one point me where is the latest Uboot version for that particular processor?

Furthermore, how do disable the watchdog completely?

thank you.

HI Gustavo

please look at: uboot/cpu/arm_cortexa8/mx6/generic.c

some board files also can access wdog, like
uboot/board/freescale/mx6sl_evk/mx6sl_evk.c

also ROM may enable wdog, check Boot eFUSE descriptions

in Boot Chapter of Reference Manual.

Best regards
igor
