In imx6UL, is watchdog (WDOGx_B / WDOG_ANY) enabled by default or need to be enable in software?

If I muxed LCD_RESET [ALT4] pin for watchdog

While power up, uboot failed to load. Will watchdog kick in?

Hi Prabhat

>In imx6UL, is watchdog (WDOGx_B / WDOG_ANY) enabled by default or need to be enable in software?

yes it should be enabled in software. Also in Serial Downloader mode it can be enabled by

fuse WDOG Timeout Select, this is described in Chapter 8 System Boot Reference Manual.

Best regards
