Schematics - sanity check list
This list, attached below, provides checkpoints for aspects that require verification because errors occur frequently. The documents cover topics such as power supply domains, system control signals (reset line, wake-up pins, and clocks between the microprocessor unit (MPU) and STPMIC), flash boot device configurations, the USB subsystem, Ethernet, and other topics.
