Reset push buttons

The V2M‑Juno motherboard provides two 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 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 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
