I tried to clean and rebuild the entire thing, but this time running env LDFLAGS=-L/usr/local/Cellar CPPFLAGS=-I/usr/local/include ./configure before make all. Brew installs everything in /usr/local/Cellar.
I also used the avrdude.conf file from the SVN version: /Users/hans/Downloads/SVN/avrdude/avrdude -Cavrdude.conf -vvv -patmega4808 -cxplainedmini_updi -Pusb Here's the output from the dtruss. It's so long I pasted everything on Gist instead of having it in an email: https://gist.github.com/MCUdude/4033c4cfdad2078845820d538e9d08f0 <https://gist.github.com/MCUdude/4033c4cfdad2078845820d538e9d08f0> BTW I don't own an Xplained Mini with an ATmega4808 soldered. I'm using a DIY Xplained Mini UPDI running on an Arduino Pro Micro. It's surprisingly reliable and stable! The downside is that the firmware is not open source, and it only supports 16-bit addressing. https://github.com/MCUdude/microUPDI <https://github.com/MCUdude/microUPDI> Hans > 14. des. 2021 kl. 21:00 skrev Joerg Wunsch <[email protected]>: > > ./avrdude -C avrdude.conf -patmega4808 -cxplainedmini_updi >& logfile.txt
