push reset switch on Arduboy and set it to flashlight mode
start uploading within the first 8 seconds after powering on my Arduboy
On every pc Arduboy was listet as “Arduino leonardo” without warnings as a regular serial device in the hardware devices list.
Any idea what’s wrong with me, my systems or my Arduboy? Is the bootloader wrong? As far as I know I never did something to my arduboy since buying it in Nov 2018. I just put a few games on it that were available as arduino project.
@sjm4306: Currently MicroCity is installed. But before I had other games installed with Arduino IDE and the same problems with Arduboy Uploader and the other tools. Whole list of games that were installed on my arduboy:
Kind of odd that avrdude doesn’t work and Arduino IDE does (it also uses avrdude) The one difference I see between the uploaders and the Arduino IDE is that the Arduino IDE has a longer retry period / connect timeout. Which makes me wonder if you’re USB cable is wonky. Have you tried another USB cable and/or different USB port?
the correct procedure should be:
Turn on Arduboy while pressing up to enter flashlight mode
start uploading within the 8 seconds after reseting Arduboy
