I have read this entire thread and it seems I have the same problem as this guy - exactly I get displayed “TMC CONNECTION ERROR” when defined drivers are TMC2208, when TMC2208_STANDALONE is used there is no error but also no UART feature.
He mentioned he got new, good drivers. Is it possible mine are faulty? I ordered them from bigtreetech (TMC 2208 V3.0, UART enabled) and they came pre soldered (I suppose) but there isn’t just soldered pads, they put some kind of resistor over it… Can someone explain please?!
