Watchdog reset on imx6ul

I am facing troubles with the watchdog on imx6ul. I am using u-boot 2016.03.


I configure:

* the WCR register to 0xFF34 (WDT and WDE enabled and timeout 128s)

* the WMCR register to 0x0000 (Power down counter disabled)

* the WSR to 0x5555 and afterwards to 0xaaaa


After 12 seconds, the board reboots and reset cause is WDOG.


If I change the timeout to 60 seconds, nothing changes. Also after 12 seconds, the board reboots.


What could cause this strange behaviour?


Best regards
