I'm using i.MX6 DL on linux system. The default WDOG signal is WDOG2(SD1_DAT3). It connect to external PMIC. Can anyone help my follow question
1. Can WDOG2 reset external PMIC when linux system is hang up? How to set it? Do I need to change to WDOG1?
2. What's the difference between WDOG1 and WDOG2? What about WDOG2 in TZ mode?
Thanks in advance.
