Check that all recommendations related to reset circuit have been applied (see
circuit design
Check that the power supply is properly decoupled (100nF + 10µF close to the MCU).
Refer to AN1709. If this cannot be done, it is recommended to put a 100 nF + 1MΩ pull-
down on the RESET pin.
The capacitors connected on the RESET pin and also the power supply are key to
avoiding any start-up marginality. In most cases, steps 1 and 2 above are sufficient for a
robust solution. Otherwise: replace 10nF pull-down on the RESET pin with a 5 µF to
20 µF capacitor.
