run_PG - GLOBAL_EN
- A button between pins 13-14 can be used to wake up compute module from power down
- If compute modules is awake RUN_PG will be high so the button doesn't do anything
If the compute module is asleep then RUN_PG will be at 0v and so pull global enable low

nRPIBOOT
Force RPIBOOT = Jumper Pins 1-2 == GND
EEPROM_WP
EEPROM write protect = Jumper Pins 3-4 == GND
run_PG
-
RUN_PG= Run / Power Good control pin. - Works like the
RUNpin on regular Raspberry Pis.
⚙️ Behavior Table
| Pin State | Meaning | Effect |
|---|---|---|
| High (default) | System running normally | CM4 operates normally |
| Low (pulled low) | Reset request | Forces a hard reset (CPU/GPU stop, power rails reset) |
| Released High | Release from reset | CM4 reboots and starts boot sequence |
