I’ve been following this documentation to build a image
But starting Kernel stops at the same place every time,and reboot after a while.And the log shows below.

I wonder if it’s causing by watchdog reset, i try to disable the watchdog in bsp setting by:
$bsp-create-settings
–type spl
–bsp-dir software/preloader
–preloader-settings-dir “hps_isw_handoff/soc_system_hps_0”
–settings software/preloader/settings.bsp
–set spl.boot.WATCHDOG_ENABLE false
but the log still shows watchdog enable.
Can anybody tell me what have I done wrong.
Or maybe it’s not the watchdog,and there are some other reasons.
Thanks a lot！
