High Performance Low Cost Embedded Systems
There is a “brightness and power” icon in the “setting” subgroup. Since our system doesn’t have
a power management circuit, this icon is not active.
Note: the original Qtopia 2.2.0 system doesn’t “shutdown” or “reboot” effectively, we changed
its code to make it work.
3.1.31 Watchdog
The “Watchdog” is a very basic utility in embedded systems. The S3C2440 chip already has a
watchdog. The latest Linux kernel has drivers for it.
