Loading DSP-Code from Linux without DSPLink/DSPBios
Added by Benedikt K. almost 11 years ago
Hej hej,
I have a coff-file with my DSP-Algorithm which runs perfectly when I start it via JTAG or via U-Boot. [Linux is up on the ARM in parallel. The communication between Linux and DSP is also working.]
Now I want to load the DSP with this coff-file from linux. I already tried to use the PROC-Module of the DSPLink, but it stalls when I call PROC_start as it waits for a response of the DSPBios - which I don't use.
Is there another way to easily get my code from the COFF-file to the DSP on linux?

Hello Benedikt,
As far as I know, we've really only had experience running DSP code that uses the BIOS. Have you downloaded and looked at our MDK or our DSP Hello World starter guide? In the MDK we have a class called dspapp that does all the necessities to load the DSP from an ARM side application. Looking into that code might give you some insight. Or you could conform your code to fit into the structure we normally use. Take a look at DSP Hello World, if you haven't already, for how we typically do things.
Hope this is helpful.
Let us know if you have any other questions.
Thanks,
\Greg
