This should work. OpenOCD supports multiple targets - some for debugging, some not, so adding a target that only supports programming should work, and the infrastructure is there.

I notice there is DSP56300 support - I don't know if it is complete, and how similar it is to your DSP56800, but it might be a start. In any case, do *not* use some snapshort release as a starting point - use the GIT repository. cu Michael _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
