When I load and run following program with True Time Simulator & Real Time Debugger ther is no problem. The "Hello World" word appears in terminal windows. But when i reset my microprocessor with K6 system power connector, a specific caracters appears in my terminal windows instead of "Hello World"
Thanks for your help.
