Make sure you understand the following statements.
-
Every power pin stands for a PMIC/DC-DC power output, whose ON/OFF, sequence, voltage, etc. have to be controlled separately. Since GPIO, SD, and QSPI may have up to 2 power voltages, there can be in total 17 power outputs.
-
CPU uses I2C (GPIO) to configure all PMIC relevant parameters.
For Hot Reset: Follow the same procedure as the cold powering-up, but only remember not to switch off the AON power supplies.
