Hello, due to the way "-F" and "-e" options operate in avrdude, jtag2updi can't currently unlock chips that way. You need to enter interactive mode "-F -t" and then use...

You can change the default values to others, if you prefer.

There is a variable meant to keep track of that, JTAG2::ConnectedTo bit 0 is a flag that is set when UPDI is transmitting, cleared when not. Anyway, the first time...

Are you sure the chips aren't locked?

Well, I didn't write this with a library type usage in mind, but all you really need to flash the MCU are the functions inside the files "updi_xxx.*" and their...

I think you messed up the latest commit to your repository, there are lots of duplicate files in the root directory that should be in the source directory.

The code cannot have unconditional dependencies on Arduino libraries, It must compile on systems that don't have the Arduino libraries installed (that is, for targets other than the mega32U4). In...

I created a branch to work on the code, since even after you address the issue from the previous comment, there will probably be more things to change before merging...

> I guess I won't go for an approach to even have the 32U4 being able to compile without Arduino libs, by picking the USB stuff from the libs. But...

So have you tried the method I explain in the documentation? > Alternatively, you can erase the chip from interactive mode, enter it using "-t", and "-F" to override the...
