Improved Leonardo bootloader (new)

[Lauszus]

This is equal to my old pull request (#93), but since I deleted the files I decided to make a new one.

The power-on reset detection didn't work properly, but has now been fixed.
With the original firmware my board always ran the bootloader. But the updated version works perfectly. The upload process (without needing to press the reset button) also works as intended.

The .hex file is compiled using the version of LUFA as originally used ("LUFA 111009").
The VID and PID are the same as the original ones, as defined in the the makefile:

USB vendor ID (VID)

official Arduino LLC VID

VID = 0x2341

USB product ID (PID)

official Leonardo PID

PID = 0x0036

I loaded the new .hex into my 1.0.1 ide by replacing the catalina-leonardo.hex with yours and then burned it onto my leonardo. It works perfectly now, if I re-power the board it loads my sketch right away rather than waiting 8 seconds to timeout as before. Thanks for the fix.

federico can you test it and report back?

It looks like the .hex file in the pull request doesn't include a sketch, just the bootloader itself. I believe that when we tested the Leonardo, we found problems on some versions of Windows when the board had just a bootloader and no sketch. So we should merge the blink sketch into the bootloader hex file.

Yes it's only the bootloader, but the fix should still be included into the bootloader.

[Fede85]

Yes, of course.
