Hello, First of all, thank you for accepting me to the mailing list. The reason I wanted to join was that I have just started working on an enhancement to AVRDUDE to support simple serial-based interface for programming newest AVR families that use UPDI protocol. I’m simply curious - would you guys be interested in accepting this work, when finished, to the main AVRDUDE codebase?
I can provide more details, should there be interest, but for now I can shortly describe the implementation process: I forked https://github.com/sigmike/avrdude repo into https://github.com/dbuchwald/avrdude, created new programmer definition, and started porting official SerialUPDI driver from Microchip (https://github.com/microchip-pic-avr-tools/pymcuprog) written in Python to C. At this I have completed implementation of physical communication layer, datalink layer and abstract readwrite layer and using these I can connect to AVR128DB64/28 and retrieve System Information Block. So, would you be interested in having this feature added to AVRDUDE codebase? Best regards, Dawid Buchwald
