4.6 Power ON Troubleshooting

Power On sequence of CU405 is :

PWR key press(Key PCB)

→

KEY_ON_SW_N go to low(D601),PM6650 KPDPWR_N pin(24)

→

PM6650 Power Up

→

VREG_MSMC_1.25V(C434), VREG_MSME_1.8V(C435),

VREG_MSMP_2.6V(C427), VREG_MSMA_2.6V(C425), VREG_TCXO_2.85V(C414) power up

and system reset assert to MSM

→

Phone booting and PS_HOLD(D400) assert to PMIC
