Another word of thanks to Simon for his writeup on reflashing the ATmega328P in the QCX. I flashed my QCX from T1.00b to T1.05 yesterday using my “original” Arduino clone. Initially I tried and failed to communicate with the QCX processor with either that Arduino or a Nano clone. Then I suspected that it might be a connection problem, as the “Dupont” jumpers I was using did not seem to fit very tightly on the ISP header pins of the QCX. Jumpers from another set I had were a tighter fit, and that solved the problem. I still was not successful using the Nano however. The faulty jumpers are on their way back to Amazon!
