watchdog timeout on Wandboard Quad

Dear all,

I want to run FreeBSD current on a Wandboard Quad. I installed
https://download.freebsd.org/snapshots/arm/armv7/ISO-IMAGES/16.0/FreeBSD-16.0-CURRENT-arm-armv7-GENERICSD-20260518-ca67cfa5237f-285947.img.xz
on a SD card and also installed /usr/local/share/u-boot/u-boot-wandboard/u-boot.imx as described
in /usr/local/share/u-boot/u-boot-wandboard/README

FreeBSD boots fine but every two minutes the watchdog timer fire and uboot boots again.

The message is:

U-Boot SPL 2025.10 (May 03 2026 - 12:17:39 +0000)

How can I avoid this periodic reboot?
