  • Actually this is a higher level question, not so much related to using avrdude with the Butterfly, but with anything on Windows 10. The other discussion will not be looked at by anyone not having experience with the Butterfly.

  • Nov 30, 2019 In the process of the optiboot-x development, using avrdude with Microchip development boards, I 'frequently' encountered situations where avrdude (and/or the Official tools) would fail to talk to the board (and the official EDBG or mEDBG chips) until it was actually power-cycled.
  • Avrdude 6.3 Windows 9 AVRDUDE, stands for AVR Downloader/UploaDEr, is software for programming Atmel AVR Microcontrollers. It provides a command-line interface for all downloading and uploading features.

This section explains how to program our 32U4 family of boards using the avr-gcc toolchain and AVRDUDE. This section is intended for advanced users who do not want to use the Arduino IDE as described in the previous section.

Avrdude is a command line program, so you'll have to type in all the commands (later you'll find out how to shortcut this with a Makefile) Under Windows, you'll need to open up a command window, select Run. From the Start Menu and type in cmd and hit OK.

Getting the prerequisites

If you are using Windows, we recommend downloading WinAVR, which contains the avr-gcc toolchain and a command-line utility called AVRDUDE that can be used to upload programs to the A-Star bootloader. If the version of GNU Make that comes with WinAVR crashes on your computer, we recommend using the Pololu version of GNU Make.

If you are using Mac OS X, we recommend downloading the CrossPack for AVR Development.

If you are using Linux, you will need to install avr-gcc, avr-libc, and AVRDUDE. Ubuntu users can get the required software by running:

After you have installed the prerequisites, open a command prompt and try running these commands to make sure all the required utilities are available:

If any of those commands fail, make sure the desired executable is installed on your computer and make sure that it is in a directory listed in your PATH environment variable.

Compiling an example program

Copy the following code to a file named “main.c”:

In the same folder, create a file named “Makefile” with the following contents:

Make sure that the PORT variable in the Makefile is the name of the device’s virtual serial port. In Windows, .GLOBALROOTDeviceUSBSER000 should work if the A-Star is the only USB device connected that is using the usbser.sys driver, but you can change it to be the actual name of the COM port (e.g. COM13).

In a command prompt, navigate to the directory with the Makefile and main.c. If you run the command make, the code should get compiled and produce a file named “main.hex”.

To program the A-Star device, you will need to get it into bootloader mode first. One way to do this is to reset the AVR twice within 750 ms. Most of the boards in our 32U4 family have a reset button that can be used to reset the board. On any of our 32U4 family of boards, a pushbutton can be connected between the GND and RST pins to serve as a reset button, or you can use a wire. Once the device is in bootloader mode, quickly run the command make program to program it. If you wait longer than 8 seconds, the A-Star bootloader will exit and the AVR will go back to running the user program.
