Have to reflash bootloader. Go to the next point.1. Go to: “Device signature” and click on “Read” button. If you continue to use this website without changing your cookie settings or you click "Accept" below then you are consenting to this.
In order to upload, the bootloader must be activated. Cost and size, just to mention a few, makes using an Arduino board in certain projects an overkill, often times its always too big, or too expensive for the scope of the project especially when it’s a project that we need to make several units. I am very glad you found it useful.Hello again. Have to reflash bootloader. For non-UNOs you'll need to swap pins 11, 12, 13 for the hardware SPI pins but we haven't tested it at all, so UNO only please. I am not 100% sure, but you should be able to wire up 16U2 ICSP same way as you wire up 328P to another arduino board. thanks for your support , i have a probleme with my arduino board , i can’t load the program in my chip , the message from arduino ide says : avrdude: verification error, first mismatch at byte 0x0000i’m tryring to figure out what’s happening because after this error the chip was acceting strange like auto-reseting , and after this i was trying change the program but this error come out , pleaze help me .
With that done, go to tools>programmer and select “With this done, You should now be able to upload any code directly from the Arduino IDE to the Atmega328P microcontroller and use it for standalone purposes.With the bootloader now on the chip, you can start uploading custom Arduino sketches to it following the tutorial That’s it for this tutorial, Thanks for reading.

How to Restore the Arduino UNO R3 ATmega16U2 Firmware Using the Arduino IDE: If you have a need to re-flash the ATmega16U2 chip with the stock firmware to restore the Arduino UNO back to normal, this is often done on the command line using avrdude or dfu-programmer, or with the Windows program Flip. Start Arduino software (Start -> Arduino).After this course, you will design your own Arduino like board. Thanks very muchFill in your details below or click an icon to log in: then could you explain in detail what does the code do ?Usually the "can only upload once" symptom is caused by a missing auto-reset circuit.
When I try to setup the AVR in Atmel Studio it will disconnect and ends up with a error.It should work even with unsigned driver. Maybe wrong driver? It’s not beginner friendly, thus to eradicate these issues, Arduino created a .hex file which can be installed on AVR chips that allow you to program the board over a serial port, ensuring all that is needed to program a microcontroller (after installing the hex file) is a serial connection between the microcontroller and the Computer which can be achieved using a USB to UART adapter. It has two ICSP headers: one for the ATmega16U2 and one for the ATmega328. Thank you for leaving your comment.Thank you Ovidiu. Program the bootloader. You'll need to do the next step quickly. Open the Arduino IDE and upload the YunSerialTerminal example to your Yún. There are different versions of the bootloader - both in order to work on different hardware and because it has changed over time.The current bootloaders (i.e. You'll need this There are different versions of the bootloader - both in order to work on different hardware and because it has changed over time. Select: “Tool” -> AVRISP mkII; “Device” -> ATmega328P; “Interface” -> ISP; and press “Apply” button.I’ve got an error which says : Unable to connect to tool AVRISP mkII (000200212345)As I said, everything seems fine, I can see the device in the device manager, as Jungo Connectivity -> AVRISP mk II, the two LED’s are blinking twice when I plug the board into USB and I checked my wires almost 10 time, always the same issue, can’t connect !I also tried the other way, by the arduino software, after flashing the correct hex file, and idem.But, i noticed when I turn my board in DFU mode with Atmel Studio, I can see it in Device Programming in the tool list as “Atmel Mega DFU”, I choose the right device and press “Apply”, I can see these informations in “Tool information” tab.But, when I try to read the device signature, I’ve got an error;Unable to enter programming mode.
