| As I told you before, you CAN NOT step through printf. Set a breakpoint on the statement right after the printf and run the code. You'll see it will run just fine. If you try to step through it, the timing of the internal UART gets messed up and nothing/junk will be transmitted. In the case of nothing going out of the port, it will appear that the simulator is stuck. |

| As Chrissy skipped ahead of me I counted out the bills in my hand Windriver Ghost. Chrissy had rolled over onto her stomach seemed on the verge of nodding off 3d Pacman. Long fake eyelashes were added and a heavy coat of mascarra applied, followed with the eyeliner Ossp Str. I began to nibble at her earlobe as I withdrew and sunk in again I18nhtml. Her little girl cotton [spam] were atop the heap I picked everything up and headed for the bathroom Rockrun. |

To get around this problem, just put a "dummy" instruction after the printf, like maybe
i=0;
you can set your breakpoint there. |
