It is imperative that you download a boot loader that matches: your micro controller (MCU), the clock speed it works at, and the UART number that is used for connecting to your computer. The boot loader can only be installed on your board using a hardware programmer - including the ones supported by WebbotLib Studio - and once done you must also check that the fuses are set as shown in the following table.
