Display comes up with garbage and I get nothing off the debug port. I've changed the OS several times to test different versions and displays. Debug port was working and is connected properly.

Hi Dan. It sounds like you're pretty familiar with the Bitsy and how to update the system files. Did it stop working after you updated a file or did something else precipitate the change?

Some things I would look at:
- Is power on the board good? You can test the various voltages esily at J19 of the personality board.
- Is there a chance a DIP switch is set incorrectly?

It's also possible that the boot code got erased during a failed update. In that case, you'll have to send it back to the factory to get reflashed.

Please let us know what you find.

I'm thinking it's the BootCode, I had issues changing to a different display and had to update the system as well, I may have disconnected the power during a transfer. Power is fine and so are the dip switch settings.
What is required to reflash the Bootcode, is it possible for me to do it.
