[En-Nut-Discussion] Troubles with uart1

[Stephen Noftall]

Hello Maurilo;

I have been able to get UART0 and 1 to work with Ethernut. There is an
option in the programming flags for Atmega103 (?) compatibility mode. When
this is enabled, UART1 is disabled, I think. So you must be in full
Atmega128 mode to have UART1 enabled. I think you also need to disable the
JTAG port in the options as well, but I do not know for sure.

Good luck!
