I've just received my new Arduino Leonardo Ethernet R3 but I'm having a real bad experience in trying to upload any sketch. I'm starting with blink as an easy project. I'm using the 1.8.0 Windows software on XP. The com port was initially COM12 but looking at other solutions to uplading problems, I moved it to COM1. It now just seems to hang at the uploading phase. The last verbose output is "Overriding Baud Rate : 115200".
I've got one steady and one flashing green LED on the PCB. During the attempt at uploading the RX orange LED flashes a couple of times, then nothing. Just the green LEDs.
The blink code uses "pinMode(LED_BUILTIN, OUTPUT);" to define an LED pin. I guess this is compatible with the Ethernet board?
I'm quite dissapointed in this first user experience. It just doesn't work. Have I got a duff unit?
I've got plenty of good experience with micros and PICs, namely writing bootloaders and production C code etc. so I've got a lot of hardware, software & debugging experience behind me.
If there's any words of wisdom or some help pointers I'd be very appreciative.
