Writing code for the M3 on the DM8148

Stephen Turner

Hi

We are investigating writing some custom code to run on the M3.  The code would talk to both the ARM-A8 and DSP.

Questions:

1. Would the code use SYSLink to talk between the 3 processors?.

2. If SYSLink, does this mean the M3 would be running SYS/BIOS?.

3. If SYS/BIOS, would this be a CCS v5 project?.

4. How is this code loaded from Linux running on the A8.  Using the same mechanism as loading DSP code?.

thanks

    Stephen,

    Yes, you would use SysLink for communication between the Arm and each of the slave processors.  Each of the slaves would by running SYS/BIOS.  If you want to communicate between slave processors, this would be done with BIOS IPC.

    The SysLink samples, which you could look at for starting your project, use makefile builds rather than CCS project builds.  This is to support command line builds.  You can still use CCS for debugging, though.

    The Arm uses the same mechanism that is used for loading the DSP to load the M3's.

    Best regards,
