Hi @Dip_2783!
I’ve noticed that several power rails (3.3VDC, 1.8VDC, VPP_2V85, and VPP_2V5) remain active at all times.
These power signals should not be connected to any peripherals that interface directly with the processor, especially during power up/down sequences.
Could you please share the connection details or schematics showing where these power rails are routed?
Additionally, can you confirm whether any of these power signals might be interfering with the PMIC during shutdown? This could potentially explain the issues we’re observing.
Looking forward to your feedback.
Best regards!
Chavira
