Can't upload code to ATmega2560 board with USB serial

[Natanael152]

Hello guys, after following this tutorial: How to Flash Arduino Bootloader without a Programmer – Welldone Blog (fedevel.com) where shows how can I burn the bootloader on my "arduino standalone" board, I'm experiencing an issue while trying to upload a code using Arduino IDE via USB serial to my board, my board is using an ATmega2560 and works similar to an Arduino Mega 2560, I burned the bootloader on the ATmega2560, and the firmware on the ATmega16U2, I can upload the code to my board with the USBasp programmer without problems, but not using the USB cable, So I have two possible theories, 1. I've burned the bootloader with the wrong fuses and bits settings, so maybe the Arduino IDE can not identify the bootloader on the ATmega2560 chip?. The images attached shows the Fuses and Lock Bits settings when I've burned the bootloader, please tell me if I have to change something in it. And the 2. Maybe is something that I have to change in the Arduino IDE settings or files.

This is the error that I see when I try to upload the code, The code I was using to test my board was blink.

• My ATmega2560 chip was virgin when I bought.
• My computer identifies my board.

Natanael152:
I can upload the code to my board with the USBasp programmer without problems

When you do that, you erase the bootloader. So you always need to burn the bootloader again after uploading via the ISP programmer before you can go back to uploading normally over the Arduino board's USB connection again.

[Natanael152]

Yeah... I know that, but after that I have burned the bootloader again, so now my ATmega2560 chip is with the bootloader...

Natanael152:
I've burned the bootloader with the wrong fuses and bits settings, so maybe the Arduino IDE can not identify the bootloader on the ATmega2560 chip?. The images attached shows the Fuses and Lock Bits settings when I've burned the bootloader, please tell me if I have to change something in it.

You should use the Arduino IDE to burn the bootloader. That will ensure the fuses are set correctly and the right bootloader is flashed.

You'll probably need to install the right driver for your AVRISP mkII, since the "Jungo" driver used by Atmel Studio is not compatible with the open source AVRDUDE flashing tool the Arduino IDE uses to burn the bootloader. You can use Zadig to install libusbK. If you have troubles after that, try using Zadig to install the libusb-win32 driver instead of libusbK. I have the best results with libusbK, but I remember one or two people who could only get it to work with libusb-win32.

[Natanael152]

OK, I have already tried that but I tried again, and I used the USBasp that I have to burn the bootloader on it, The AVRISP mkll that you saw was a clone, I've tranformed the ATmega16U2 into a AVRISP clone to use with ATMEL studio, this was in the tutorial that I was following.

So, I have burned the bootloader with USBasp and this was the result message:

avrdude done.  Thank you.

And I still can't send code using USB cable.

I have also found that I can make loopback test with my board, but I have never done that, so I have followed the instructions and the letters that I type in the terminal is not echoed back but every time that I type a letter, TX and RX LEDs on my board blinks, So I don't know if my board passed in this test.
