Hi. I 'v got the error message launching debug session in ISS mode:"unrecognized command line option -- stdin== null.... unrecognized command line option -- stdout== null... unrecognized command line option -- stderr== null..." . I have no stdin/out devices in my project (no uart). So in syslib i'v set values of stdin/stdout/stderr to null. Is it possible to debug such a project in ISS mode. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif Beforehand thanks.
In version 1.0, a limitation of the ISS was that it required a system with a printable device for successful simulation. I recommend upgrading to version 1.1, where this limitation has been addressed, to debug systems without host communication devices.
