Pi4 bootloader update / change to halt behaviour

Thu Jul 18, 2019 8:11 am

Apologises for the cross-post but the updated Pi4 bootloader might be of interest to anyone working on HATS.

During HALT the default behaviour will be low power mode where 3V3 remains on. It's possible to revert to the previous power-off of the PMIC via an EEPROM config setting
