Hi all,
While reading the i.MX28 Reference Manual, I found that core can track battery voltage via a LRADC channel, and power itself down when it sees voltage falling below a certain threshold (notifications are sent via interrupts). However, is this logic supposed to work when the core is suspended (e.g. by pressing power switch button?) I'm using IMX28 EVK for my testing.
Thanks!

Solved! Go to Solution.
The brownout detector is a hardware block and will continue to work when ARM core is stopped on system suspend.
