Loading Different images
I am trying to load different images onto the TMS320c6678 cores, then have the different cores communicate back and forth with each other, either with some sort of messaging system, or by writing to the MSMC.
I started by looking at the 'multiple image' example in the TI wiki: "Using DSP/BIOS on Multi-Core DSP Devices". The code compiles, and to start off, I tried only running two cores. When I try to load the images onto the core, core 0 loads, but core 1 has the following error:
C66xx_1: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.C66xx_1: Trouble Writing Register PC: (Error -1176 @ 0x225DA0) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.681.0)
The original example is for c64xx device, so in the project properties, I changed it to a generic c66xx device. Advanced settings:
compiler version: 7.3.6
Output format: legacy COFF
DSP/BIOS version: 184.108.40.206
I am not too sure how to go about fixing this.
