Using Microcomputer Mode with DSP/BIOS - freesampleic - Nov 29 7:09:00 2002

I am having trouble switching the C5402 DSK to mircocomputer mode using DSP/BIOS. The way I did it was by changing the MP/#MC bit of PMST register value within the DSP/BIOS cdb file. However, my program does not run correctly afterward. It ran okay before when I used microprocessor mode. The MP/MC# bit was the only thing I changed. Are there anything I need to do?

All, Hopefully it is not a too late answer. To run 5402 DSK into correct MC/MP mode, there is a small switch on DSP board. I can not recall which is which. You can easily find the info on manual. Hopefully, it will help. Henry --- freesampleic <> wrote: > I am having trouble switching the C5402 DSK to > mircocomputer mode > using DSP/BIOS.
