Loading DSP program from ARM (OMAP-L138)

Other Parts Discussed in Thread: OMAP-L138

Hi,

I would like to know if there is a easy way to load/start a DSP program from ARM?

I have read a bit about DSP Link and studied some examples. What I want is just to start the DSP program, I don´t need any further communication between ARM and DSP.

Is it possible to just burn the code to flash and read it at boot and then just execute it somehow?

Kind Regards,

Jonas

    In general the easiest way to do this is use DSP Link, and start with one of the examples from the wiki, and simply remove any code which communicates back to the ARM. This would make for an extremely simple DSP Link program on the ARM, about as simple as they can get. Anything else would require some effort in developing code to unpack the DSP executable and start the DSP running, essentially re writing a portion of DSP Link.

    On OMAP-L138 the ARM boots first, so to leverage the DSP you will have to do some work on the ARM, this is essentially what DSP Link does for you. I imagine you are still planning on running something on the ARM (Linux maybe)?
