2.6.1

Reset push buttons

The V2M-Juno r2 motherboard provides the following reset push buttons.

Hardware Reset push button

Pressing the

Hardware Reset

button during runtime generates

nPBRESET

, that performs a hardware

reset, and puts the system into standby state.

Note

The

Hardware Reset

push button is the black push button. The V2M-Juno r2 motherboard labels it as

nPBRESET

ON/OFF/Soft Reset push button

Pressing the

ON/OFF/Soft Reset

button:

• Briefly during runtime performs a software reset of the system.
• For more than two seconds puts the system into the standby state in the same way as pressing the

Hardware Reset

button.

Note

The

ON/OFF/Soft Reset

push button is the red push button. The V2M-Juno r2 motherboard labels it as

nPBON

When you use the system with bare metal software, you must make the following setting in the

config.txt

file to enable direct control of the OFF/Soft Reset feature:

PBONFORCE: TRUE ;RED PBON push button directly drives RESET/SHUTDOWN
