To debug, we can use another opensource, AvaRICE (from ubuntu, just do “apt-get install avarice”).įor example (this is just to show how to use it, as my ICE stick is not connected to any target device yet so it reports it “No configuration available for device ID: ffff”):
$ sudo avrdude -c avrisp -P /dev/ttyUSB0 -pm328p To use it as programmer, we can use avrdude: usb 3-2: ch341-uart converter now attached to ttyUSB0 usb 3-2: New USB device strings: Mfr=0, Product=2, SerialNumber=0 usb 3-2: New USB device found, idVendor=1a86, idProduct=7523 usb 3-2: new full-speed USB device number 6 using ohci-pci
ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0 Upon inserting the stick to my PC’s USB (running Ubuntu Linux):
