Re: Help needed to update QCX firmware #qcx #firmware

Podolsky A did it! You put me on the right track. After reading your post, I went back to inspect the jumpers connecting the QCX to the Arduino. Lo and behold, I discovered that one of the pins on the QCX (it happened to be the MOSI pin) had a bad solder joint. I re-soldered it, reconnected the jumpers and VOILA!!! Now AVRDUDESS correctly detected the atmel chip and then correctly programmed the firmware. Thank you. Thank you. Thank you!
