Is anyone out there experiencing the same problem?
Uploading a sketch from the Arduino IDE (v0018) gives me this error message:
Binary sketch size: 16080 bytes (of a 30720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x02
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x02
If I re-flash the bootloader, I can upload a sketch just fine.
But it works only once. The second time I want to upload a sketch,
I get the above error again.
It looks as if the sketch upload erases the bootloader somehow.
I use Adafruit's USBtinyISP to burn the bootloader.
