Would chavrprog work with Arduino Leonardo bootloader ?

[mycodedoesnotcompile2]

Hello @Trel725,

As your chavrprog looks very interesting, I was wondering if you think that programming the official Arduino Leonardo bootloader with your tool (hence, with a 341a, that I don't have yet) would work ?

Here is the official bootloader for Leonardo:

• definition: https://github.com/arduino/ArduinoCore-avr/blob/63092126a406402022f943ac048fa195ed7e944b/boards.txt#L416
• hex file: https://github.com/arduino/ArduinoCore-avr/blob/master/bootloaders/caterina/Caterina-Leonardo.hex

If I take inspiration from this, would this work? $ sudo ./chavrprog -d mega32u4 -a s Caterina-Leonardo.hex

Or do I need an actual ISP programmer (USBtinyISP etc.) to achieve bootloader programming to a Leonardo ? Best regards.

Hi, sure, that's exactly the purpose of the project. I will close the issue, feel free to reopen if you have more questions.
