Taking a quick look at your schematic, here is my feedback:
- Would recommend adding a limiting resistor to your crystal oscillator, even if you just use a zero ohm resistor.
- Would recommend exposing the remaining IO as a pin header or connector, though maybe these are on a different page because I don’t see your SWD connector here either
- DRV8316 buck starts in 3.3V mode by default, and the diode forward voltage plus LDO dropout voltage might be too low for the mcu in this initial condition.
Other than that, looks pretty good!
