Stuck at start-up screen

Hi,

My MD is stuck at the <MegaDrum.info> start screen.

It is supposed to jump to a second screen but it doesn't.
Anyone any ideas on this?

Make sure you have a crystal with the right frequency. It's all I can think of other than checking for shorts/breaks etc.

Or maybe you have problems with inputs and they start triggering constantly overwhelming MCU.

And the winner is ignotus.
Short somewhere between the "PB0 (644) and A (4851) line" and ground.
Couldn't really see it but after some scratching in some tight places it came to life.



thanks
