After printing some messages the systems freezes for a while and then continues executing. It looks like some buffer gets full and time is taken to flush it. For a very simple application, which basically loops forever and prints some messages after every tick (using cyg_thread_delay(1)) this is happening. The same application running on the iPaq works fine (and I'm also sending messages through the serial in a 1 tick basis). Any guess on what might be causing my system to freeze? Is there any buffer in which diag_printf messages are put into? Thanks, Cristiano. ------------------------------------------------------------ Cristiano Ligieri Pereira - http://www.ics.uci.edu/~cpereira
