This is OK, you have Arduino connected with computer using COM3.

 

But Arduino bootloader port is not COM3, is ab new port that open only for 8 seconds when you short Reset pin to Ground pin twice (fast).

 

Tick the "Start load firmware..." for don't loose the "window".

I did it really fast... like 50 times. I even tried in russsian, always the same result. Tried on w10, w7,forcing drivers, diferents pcs, no antivirus, trial mode, you name it...

 

 

 

Eventually fond THIS https://sourceforge.net/projects/arduinodev/files/ArduinoBuilder/FreematicsArduinoBuilder-1.0.13-win32.exe/download

 

 

With it I was able to upload the hex file. I´ve tried X-loader first and it wouldnt work either. I think im having some funny interaction or something, it can be that I wasn´t able to google someone with some similar problem.

 

 

Thanks for the response! Im gonna go now to have some new problems configuring those allegro sensors! :megalol:

Can be something wrong in the generation of this command?

You have set the wrong COM port. When you reset the Arduino it will show the bootloader COM port. Thats the one you need to enter in the (green) COM port window.

 

 

Thanks for the response! I think I have it right, I quickly check wich one appears in the device manager and check that is the same in the "green box"

 

 

Can it be not founding avrdude.exe or something alike?

Sorry if it sounds silly, or poorly redacted, I am not programmer, neither am an english native speaker. thanks!

Cant update firmware

 

Hi; I have been trying to upload the firmware to a Arduino Leonardo board, followed the guide, forced the drivers to be recognized as arduino leonardo or arduino leonardo bootloader, reset, upload firmware, but it gets stuck in "connecting to programmer: . _ "

 

 

I have tried everything that could come to my mind. I always get that result.
