Hi, I've an idea. Maybe wrong, but I have one :) Since only 2 LSB are actually used as extended fuses, I guess programmer or avrdude can ignore "unused bits" (like using some mask). Point is, that there may be bug in programmer FW or AVR chip description (which avdrude use), so one bit can be interpreted bad. But if you check your fuse values with register, I think you does not have problem (2 LSB are same in both cases). Or maybe you set unsupported baudrate (on some USB <--> UART convertors it can be problem). Regards Martin On 29 Mar 2016 17:40, "Armin Oonk" <ar...@berkelaarmrt.com> wrote:
