Check that the power supply is properly decoupled (100nF + 10µF close to the MCU).
Refer to AN1709 and AN2017. If this cannot be done, it is recommended to put a
100nF + 1MΩ pull-down on the RESET pin.
The capacitors connected on the RESET pin and also the power supply are key to
avoid 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 5µF to
20µF capacitor.”
