I do not know if the bootloader is installed. What is the way to know this?
If not installed what should I do to install it?
On my Arduino Uno platform I have a code which runs ok for my application. When I replace the original Atmega328P-PU by one that I bought, the code uploading does not complete. The error message is the same as when I use a blank Atmega: "not in sync".
