Exchange crystal to 18.432 MHz

Hi

On my Gen6-Mod-Board I exchange the original crystal to one with 18.432 MHz.
This has the effect of matching the perfect data rate without any variations.

That's not necessary. Nearly all user works with little deviance of the baudrate.
And it works fine.
But I want the perfect match to ban future problems.

Before that, I used a crystal with 20MHz and 250000 baud with the RepetierHost-Programm.
Also a perfect match.
Unfortunately this data rate is not supported in mono on Linux.
So I used for Reprap a virtual machine or windows.
Very annoying.
I could use an other baudrate but I don't want to.

Now with 18.432Mhz crystal and 230400 Baud, it works direct under Linux.

I compiled the bootloader from Peter Fleury of Traumflug's github.
who contributes a litte patch.

I compile it for some MCUs. But I only know for the Atmega644 that it works.

For upload the bootloader see:
