I am new to iMX6UL processor. When I look at iMX6UL EVK board, I notice that the reset switch and software watchdog reset connected to the enable pin of DCDC_3V3 power regulator through a reset IC. So, If the user press reset button or software generates a watchdog reset event, the iMX6UL will be powered off. My question is:

  1. Why the reset will power off the iMX6UL? In most cases, the Linux is running on iMX6UL. A power off reset may cause the data lost other issues. Is that a concern?
  2. What if the reset signal goes to nPOR pin of iMX6UL? Any down side of it?
