Why do the LED's not light up when I try using the mpc555rt_led model with Embedded Target for Motorola MPC555 1.1 (R13SP1)?

I am trying to use the mpc555rt_led model with Embedded Target for Motorola MPC555 1.1 (R13SP1). When I build using the build action "Run_via_BDM", I get a successful build procedure and a Metrowerks source statement "program is executing", but the LED's on the development board I am using do not light up. Everything seems to be setup correctly but the application does not seem to run.

On different eval boards, the LEDs are connected to different digital outputs. The model mpc555rt_led will only flash LEDs when run on the Phytec eval board. If you are using a different board, it may be that the application is running correctly, its outputs are just not going to the LEDs. Double check that you are using the digital outputs that go to the LEDs on your board.
