It works now, I was trying to change the clock from high to low for writing to Flash, and I found in Errata it is a problem to do that, so I take that away and use function i RAM instead to handling the Flash
Did you resolve your problem and if so what was it and what did you do to fix it ? Has anyone else had similar problem ? (And found a fix that they can share ?) I migrated my project to the IAR 5.1 compiler (using latest silicon - STR911 FA). The project runs with j-Trace plugged in, but not without it. Thanks, Rhys
