Hi ,

      I found an interesting problem while i debug the example HELLO WORLD. The software delay function sometimes causes 1.8S delay and  sometimes causes 1.5S delay. Just shown as pictures bleow. The only different is the address where while(i--) placed. Can someone tell me why?  Thanks!

Hi Lukas,

  Thanks so much for your advice! I solved the problem through enabling instruction cache.
