Today I got Arduino Leonardo to replace my Uno. I've tried running one of sketches I use on the Uno, but with no luck. When I start the upload, RX LED on the Leonardo flashes few times, and after several seconds, L LED pulsates and I get this message:
avrdude: ser_open(): can't open device "\\.\COM9": The system cannot find the file specified. avrdude: ser_send(): write error: sorry no info avail
I've checked in Device Manager, where it says that Arduino Leonardo is on COM3, and COM3 is also set in Arduino IDE.
However, when I change COM port to 9 in Device Manager and also in Arduino IDE and then try to upload the sketch, things start to roll out like above, but this time IDE freezes for 5-10 mins on "Uploading..." part, and finally unfreezes with this message:
Found programmer: Id = "B¨J"; type = Software Version = avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?
Several more infos:
- OS: Win7 64-bit - Arduino IDE: 1.0.5-r2 - Other serial devices: Only Bluetooth that I've manually assigned to COM200, to avoid possible conflicts.
