I suspect that you select the incorrect *.cfg file, which is used for CW to download code/data to flash in downloading process. This is the procedure based CodeWarrior for DSP56800/E ver8.3:
1)On CW IDE, pls press "ALT" plus "F7" button, the "smm pROM-xRAM settings" menu will appear.
2)click "Debugger->M56800E Target Setting", the "M56800E Target Settings" will appear.
3)check "Use Initialization file" box, select "56825x_flash.cfg", if the box is empty, pls click "Choose" button to select correct one in the directory:
C:\Program Files\Freescale\CodeWarrior for DSC56800E v8.3\M56800E Support\initialization
the Initialization file, "56825x_flash.cfg" was present but still it didn't work. when i tired debugging in simulator mode it was displaying an unknown program is running.
