Acknowledgements

First, I would like to thank everyone who made the work described here possible by making their work public:

• RikusW, who published his results on reverse engineering the debugWIRE protocol,
• dcbrown, who wrote dwire-debug, a debugger using only an USB-UART converter. I was never able to get it running on my Mac, but it provided me with a lot of important information.
• DeqingSun who was the first one to integrate the open-source debugWIRE GDB server dwire-debug into the Arduino IDE 2,
• wholder, wo wrote the Uno-based debugger DebugWireDebuggerProgrammer,
• jdolinay, who wrote the GDB remote stub for AVRs avr_debug,
• MCUdude, who is the author of MiniCore and MicroCore, and
• SpenceKonde, who is the author of ATTinyCore.

Of course, my thanks go also to everybody else, who contributed to the Arduino project.

Last, but not least, I would like to thank everybody who contributed to dw-link:

• kristianwiklund, and
• MikeChen08.
