Soft Reset
Net+OS provides an internal facility to enact a soft reset, but it is the responsibility of a
specific implementation to choose a reasonable trigger to invoke it. One choice is to use a
GPIO pin as a signal to trigger a soft reset. The Digi Connect ME has one GPIO pin named
"/INIT” (PORTC5) that is not normally assigned to any other task. It is an ideal candidate
for a soft reset. The signal is exposed via pin 20 on the 20-pin header, so it can be
controlled by an embedded host. When plugged into the development board, the /INIT
signal is pulled high, unless a jumper is placed across pins 2 and 3 of jumper block P12. In
this way, placing the jumper simulates pressing a soft reset button.
The naresetapp example application demonstrates a simple mechanism for monitoring a
GPIO pin and then initiating a soft reset when the pin achieves a particular value.
