01:12 <re_irc> <ignormies> almindor: My MISO pin is both unconfigured in the software ("NoMiso"), and the pin that _would_ be the one to use is floating, so I don't think that's the cause here unfortunately

06:54 <re_irc> <jannic> I don't know about this specific instance, but afaik some chips don't like floating pins. Perhaps pull it to some defined level?

06:55 <re_irc> <jannic> (I don't see how that would interact with the compiler optimization level, though)

06:56 <Darius> a lot of micros have internal pull up/down (or keep) you can enable

06:57 <Darius> if it is not connected then it should either be an output or have a pull up/down and set as input
