+# This describes the story of trying to get the Pi to shutdown and reboot using a single power-button
+
+## Findings:
+ - gpio-shutdown interferes with I2C pin, we need to either move gpio-shutdown or i2c to different pins
+ - GLOBAL_EN does not seem to be useful to send a halt signal, shorting it to ground is equivalent to disconnecting the power (somehow) and thus will allow it to boot up, and hard-reset but thats it
+
+
+# Things modded:
+
+ - Installed the rpi-eeprom package documentation from Rpi themselves [here](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#raspberry-pi-4-bootloader-configuration)
+   ```To view the current EEPROM configuration:
+    rpi-eeprom-config
+
+    To edit it and apply the updates to latest EEPROM release:
+    sudo -E rpi-eeprom-config --edit```
