(1)  GPIO reset button 

The reset button is connected to one GPIO which means controlled by software. 

When you press down this button by using a sharp pin, it arouses attention of CPU. Then CPU asserts the 

master reset low signal to start the system reset session. 

 

Below is the reboot screen after reset 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note: Since this reset function is controlled by software so it has no effect during boot-up session. 

 

(2)  More push button functions 

System developer can program this button to have more functions by different press-then-release delay time.
