Blink example on Mega2650 and 0019

Blink example compiles find on both 0018 and 0019
Run fine under 0018, uploads on 0019 without error, but doesn't blink the LED

Any suggestions ? :frowning:

What changes have you made to 0018 and 0019 to allow you to compile and load programs on to the 2560 (I assume you mean 2560 and not 2650)?
