upload protocol (avrdude: stk500_recv(): programmer is not responding)

Hello
I have an upload problem on an arduino.

I explain, I posess an arduino uno, I want to upload the code blink (example in the official IDE). the compilation is going well, the problem occurs when the upload starts.

ERROR LOG :

vrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x4d

LOG : https://hastebin.com/sahehofuje.coffeescript

tried to reinstalled the driver and the IDE tested several usb port, I tested with platformIO. with a new installation of windows.

but the problem persists ideas?

ps: sorry for my average english, it's not my mother tongue

Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have the correct board selected from the Tools > Board menu.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

I have just recently started getting these errors too.

avrdude: stk500_recv(): programmer is not responding

Sometimes it will do exactly as the original posters did, but other time it gets further along and the error. Other times it will "stutter" by working, error, start working, error, start working and then error saying the programmer is not responding. Very strange. Almost like the baud rate is to fast??

avrdude done.  Thank you.
