Hey, help. Suddenly I cant progrram my arduino. Why Please help me.Thank you
I do have the same problem,If I upload a sketch by Uspasp from the IDE (v1.0.1), the sketchs work fine.But I can't upload sketches anymore by the arduino ide.I think the bootloader is over writen.Burning a new bootloader, solves the problem.If you upload by extrenal programmer, you erase the flash memory, and then uploud the sketch.(so you loose the bootloader). Is there a option to prevent that ?
