[En-Nut-Discussion] SAM7X using 20Mhz rather than 18.432Mhz

[Dave Warren]

I am designing a board at the moment using the SAM7X256 and intending to run 
ethernut. I have no use for USB so I am not tied to 18.432Mhz. How difficult 
is it to alter the ethernut for a different frequency, I already have 20Mhz, 
I want the uarts to still have correct baud rate, timers to work processor 
PLL be set up ect. Can anyone give a hint at where to look in the code?

Best Regards
