I'm new to emended system and PCB design. This will be my first PCB design.

Before moving to PCB design just want to confirm that my circuit will work. Kindly review schematics. Any Feedback is appreciated.

Im getting this error and warning in ERC.

Error: Input Power pin not driven by any output power pins

PIN 43 VLXSPMS

Error: Input Power pin not driven by any output Power pins

Pin 14 VDDA

Warning:

VDDA & VREF+ are attached to same items; VDDA will be used in netlist

VDD and VDDSMPS are attached to same items; VDD will be used in netlist

I have used AN5165 Application note Hardware guide from ST ,VFQFPN68 reference board

Hey, did it work? haha

I'm working on STM32WB55RG and I don't want to spend a month analyzing connections on data sheet.
