When I upload a program to my ATMEGA328P-PU, standalone or on a UNO board, I get the following error message:
Without verbose mode:
Arduino: 1.8.12 (Windows 10), Board: "Arduino Uno" Sketch uses 25702 bytes (79%) of program storage space. Maximum is 32256 bytes. Global variables use 1048 bytes (51%) of dynamic memory, leaving 1000 bytes for local variables. Maximum is 2048 bytes. An error occurred while uploading the sketch avrdude: verification error, first mismatch at byte 0x0000 0x62 != 0x0c avrdude: verification error; content mismatch This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.
With verbose mode on: Due to its number of characters, I will attach a TXT file with the log
BTW, I have checked the Serial Port.
This error is given with any programme, including basic examples.
Thanks in advance,
