FIFOed UART BSP errors

Hi Equinox,

I don't know what can be your problem.

I have used the example code above and it was working well with my hardware: pc hyperterminal <-> ftdi chip <-> nios with fifoed uart.

maybe read again the documentation:

http://www.alterawiki.com/wiki/fifoed_avalon_uart

set the same rate at both side of the uart and try first a slow rate.

If it still doesn't work you can try to instantiate 2 uarts in a nios then connect them together (uart1_rx<->uart2_tx / uart1_tx<->uart2_rx).

Then in a nios software project try to send data and receive data, maybe only a simple char first.

It will help you to understand how it works.

good luck.
