my solution was to replace the capacitor C14 since its value in Ohms was very high

Hello. Today I defeat the subj problem. The culprit was C14 capacitor 0,1 uF. It's resistance, when measured directly in the circuit was only 28K. C14 is in parallel of RESET button, and MCU was in constant reset mode. I delete C14 and everything became ok. If you have the same problem, measure res...
