You will have to change the crystal from 14.745MHz to 16MHz...

Subject: [En-Nut-Discussion] Serial Baudrate of 1Mb by the Ethernut3


I try to make an Ethernet to Serial Gateway with a serial baud rate of
1Mb. The serial interface will work with TTL levels and connect the
gateway MC with the Control MC of my application.
My application ist based on the rs232d example. Now i can't setting up
the speed to 1Mb. I get a frequency of aboaut 921600.
How can i adjust the baud rate mor or less exactly to 1'000'000? Must i
change the CPU clock frequency of the Ethernut3 or can i change the baud
rate more exactly with an other solution?
