Why does G27M/G27D does not power ON/OFF when RTC battery is connected?

As tested in G27D iWave devkit,

  • Once “poweroff” command is given, SOM will be completely OFF.
  • To power ON the SOM, switch OFF and switch ON the Power ON/ OFF Switch present in the G27D devkit.

G27M SOM Power ON/OFF:

  • Once “poweroff” command is given, SOM will be completely OFF.
  • To power ON the SOM again, the switch present in the SOM can be pressed for maximum 2secs. This case is valid with or without connecting the RTC battery.
  • After the first power-ON, power OFF the SOM by a long press of the switch present in the G27M SOM.
  • After this, G27M SOM can be booted only by pressing the ON_OFF_BUTTON (switch present in the SOM). This can be done only when RTC battery is connected.
