i connected one of my debug output pins directly to the rxd input pin of the uart to see what enters the uart but again a perfect signal.[/b]

so it's not the comms hardware.

we have checked the settings of the uart to see if the os does the right stuff.

you can also try hardwiring the uart speed.

the nios uart now gets remove in this application by an ip core developt here that is capable to handle multi master, self arbitrationing, ... and runs at 16mbit on the same targets as the uart.

sounds like the best plan. just out of curiosity, how fast was this uart supposed to run?
<!--quotebegin-mschmitt@Aug 29 2005, 10:42 AM i want that uart working to have in my mind that i can use it in the future again. so i will investigate as soon as i find some time for this. currently the solution with the uart is useless for an industrial enviroment. but in the current app the uart was temporarily until our ip was available. --- Quote End --- The Nios UART never came across to me as being very robust; it's not like the 6811's UART with its majority-sampling and noise flags. I'm not sure it was intended to work in an industrial environment as much as be a debug console port.
