    Question thread: Develop DSP device driver for Gumstix OMAP3530

    Hello bsp, Here I am again. I finished my Coff Parser, and now I can use my User program to load bin file to DSP (mmap, but still map to L2RAM...). Much better than recompile every time... I tried to toggle an LED using GPIO, I did see LED blinking. But I keep get kernel warnings: In-band...

I used while(1) and remove the mailbox operation from...

    Question thread: Develop DSP device driver for Gumstix OMAP3530

    Hi all, First I wanna thank Bastian for answering my questions. Actually, I'm writing this DSP driver just for fun (to run computation is not my main purpose). My purpose, for this "hello world" stage, is just to learn the basic kernel stuff and low level device driver experience. So I was...

    Question thread: Develop DSP device driver for Gumstix OMAP3530

    Hi bsp, I was developing a minimum "DSPLink" as well but for Gumstix Overo (OMAP3530) to use DSP to do extensive computation. It seems like what you've done is exactly what I plan to do. I'm not very experienced in this but I did read a lot of reference manuals and have some knowledge of...
