How to start the DSP code from the ARM on the DM814x after U-Boot?

Milos Alavanja

I am running the ARM after power up to initialize the hardware via U-but and how to jump to the DSP to run its own code.

I am using Linux for the U -boot and Windows based CCS5 with the BIOS 6 to build the DSP image.

Are you looking for just development-time direction, or a runtime solution for a deployed system? For development-time, there may be some GEL files around(?) to do what you're looking for.

In a deployed system, we recommend using SysLink for this. If you don't want to use SysLink, you can at least dig through it as reference (though admittedly it's tough to dig through blindly).

I found some code related to what you're looking for in SysLink's packages/ti/syslink/family/common/ti81xx/ti81xxdsp/ directory. You can review the DM8168DSPPROC_start() fxn in Dm8168DspProc.c.
