TCF/TCI file questions

Added by Tom Riddle almost 3 years ago

Hi,

I'm on the DSP development learning curve and have been merging source from the dsplink examples from the TI DVSDK into the 2014 MDK. So when comparing tci files from the DVSDK message.tci to the Critical Link supplied /sw/DSP/templates/criticallink/platforms/MityDSP-L138/Platform.tci there are many more entries in the latter. I understand it is more explicit with memory settings and the like, but is there documentation that outlines the options/commands when creating a custom tcf/tci files. I see bits and pieces of usage examples in docs like the dsplink users guide, the porting guide LNK_017.pdf seems to be a bit more detailed but nothing that specifically addresses it.

Also we have an L138 module with 256Mb of ddr, the MDK tci file looks like 32mb are allocated to the DSP, but where can I find how much is set for the OS?

Thanks, Tom

I don't know hopefully someone else can answer this.

The memory allocated for linux is configured in the bootargs passed to the kernel. The mem= paramter controls how much ram the kernel is allowed to access.
