Atmega328p and cp2102 with error avrdude: stk500_getsync(): not in sync: resp=0x00
Researching a little and found the solution! In addition to capacitor 104, its necessari need to add a 10k resistor by connecting the 5 volts to pin 1.

This is the link of the GitHub project where I found the solution with the assembly scheme, I hope this helps somebody else!
