my first post here. Thanks for having me. I've seen many posts discussing the use of GLOBAL_EN and GND for turning the Pi4 on. I'm interested in using this to turn the Pi4 OFF and leave it OFF long term when necessary. I'd like to use a SPST switch to turn off the Pi4 and would like to know if it will cause damage to leave it in this state long term. I have confirmed on my Pi4 that shorting these pins does remove power.
As I understand from this post that:
shorting GLOBAL_EN to GND will in fact boot the RPi 4 from halt, poweroff or shutdown when the EEPROM firmware is configured iaw the documentation.
Also from this post that:
GLOBAL_EN is connected to the PMIC. Connecting it to Gnd stops it working, so all power rails die. Releasing it allows it to sequencially bring up the power rails, so allowing the SoC to start booting
My intention will be to use a wifi smart plug to power cut mains power from the Pi4 but in the case I forget that I shut it off with the SPST switch could that cause an issue? I'm assembling something similar to this Pi rack mount but they only provide details for the Pi3.
