The S5M8767A can't know status of ap reset. So, After AP watchdog reset, AP can't boot normally. Problem can be happened like below condition. - AP Bootable lowest voltage(vdd_arm): 0.9v - AP DVFS voltage table: 0.8v, 0.9v, 1.0v - During AP works on lowest voltage(0.8V), watchdog reset is asserted - AP can't boot, because vdd arm is still 0.8v Solution - Basic concept: After ap watchdog reset, GPIO configuration is changed by default value - S5M8767A has function of voltage control with gpio (8 levels with 3 gpios) - Set bootable voltage on level 0 -> can work with default gpio configuration - In the probing, Change voltage control level from level 0 to level 1 - Execute normal dvfs operation on level 1 - After watchdog reset, ap gpio is set by default value - PMIC operation mode is changed by ap reset (level1 -> level0) - Regardless of previous vdd_arm voltage, AP always can be booted.
