Hi everyone:

    I'm using beagleboard-xm with dm3730 to develop android. Now i want to deal with dsp,but i don't know how dm3730 to  inter-processor communicate to dsp.\

    Whether anyone would tell me the tools,or how to configure the development environment to process dsp? I dowload the rowboat Gingerbread_2.3.4 android source and ti dvsdk4.0.3.
