I have the CLAmath source project and open and it has a few different build options:
CLAMATHLIB_STD
CLAMATHLIB_FPU32_SUPPORT
CLAMATHLIB_DATAROM_STD
CLAMATHLIB_DATAROM_FPU32_SUPPORT
So, I am having trouble finding information on what DATAROM means, from what I gather it stores the math tables in Data ROM.
What I've been doing up to now is just using CLAMATHLIB_FPU32_SUPPORT and in my cmd file, I copy the math tables to CLA Data RAM 2 (L0DPSARAM).
If I compile and use CLAMATHLIB_DATAROM_FPU32_SUPPORT what do I have to change in my cmd file? Take everything out about the tables? It is handled automatically? I tried this, and I get errors about unresolved symbols (tables). Should they be being copied to another memory section instead of DLA Data RAM 2?????
Below is my cmd file for reference
