--- Comment #14 from abebeos at lazaridis dot com --- (In reply to Georg-Johann Lay from comment #12) > [...]you'll have to resolve conflicts. (In reply to Georg-Johann Lay from comment #13) > FYI, avrtest is here: > https://sourceforge.net/p/winavr/code/HEAD/tree/trunk/avrtest/ Thanks a lot. I tested a dozen repos / scripts with avr-gcc tool integration (which include the tools/libs you mention, including avrtest and others), but always... conflicts, even in the 5.x line. Looks better today, though, after days of trouble, I'll invest two more days to create a minimal setup, based on the xp gained. Assuming that gcc does no automated regression tests currently for the avr target?
