Using the routines of "times.h", I am able to get Tue, 09 Feb 2010 22:25:43 GMT Jiri Gaisler http://tech.groups.yahoo.com/group/leon_sparc/message/16885 http://tech.groups.yahoo.com/group/leon_sparc/message/16885 ... So, disable it and rebuild the model. The UART test bench will not pass if this is on... Jiri.

The Accelerated UART tracing is enabled. I tried too simulate with an older version of modelsim (PE 6.1b) and got the same results...

Works fine now, thanks for your help.

As you may have noticed this is not one of the supported OSs.

I got it working through using make ise. I had to edit the .xst file to change the target architecture and something may have got Tue, 09 Feb 2010 10:47:28 GMT y http://tech.groups.yahoo.com/group/leon_sparc/message/16875 http://tech.groups.yahoo.com/group/leon_sparc/message/16875 Hello, I have improved the timing performance and tried a simple hello world program. It works now. But when I download a complex c program to the board, the Tue, 09 Feb 2010 10:25:21 GMT Jan Andersson http://tech.groups.yahoo.com/group/leon_sparc/message/16874 http://tech.groups.yahoo.com/group/leon_sparc/message/16874 ...
