Hi everyone,
I am trying to program a CLA of a TMS320F2838x with tables loaded into the CLA ROM, but a lot of warnings appear due to the CLA Table symbols loaded into the ROM section:

If I have a look into the *.map file I can see that the CLA Table has loaded as it should be. Here you can see the symbols fitted to the address range of the CLA ROM (0x01001000 to 0x01001FFF):
page address name ---- ------- ---- ....abs 01001e54 CLAsincosTable_Coef0 abs 01001e56 CLAsincosTable_Coef1 abs 01001e58 CLAsincosTable_Coef1_pos abs 01001e5a CLAsincosTable_Coef2 abs 01001e5c CLAsincosTable_Coef3 abs 01001e5e CLAsincosTable_Coef3_neg abs 01001d4a CLAsincosTable_Cos0 abs 01001d0a CLAsincosTable_Sin0 abs 01001e52 CLAsincosTable_TABLE_MASK abs 01001e4c CLAsincosTable_TABLE_SIZE abs 01001e50 CLAsincosTable_TwoPiDivTABLE_SIZE
...
I understand that the CLA data ROM address range (25 bits) exceeds the CPU address range (16 bits) but the compiler should be ready for this situation, isn't it?
For further understanding of the configuration I used, the compiler version used int his project is TI v20.2.2.LTS.
I also followed all the configuration steps in the file C2000Ware_3_02_00_00\libraries\math\CLAmath\c28\docs\CLA_MATH_LIB_UG.pdf and my project is configured this way:
- CLAmath.h is included in the project
- Correct CLA2 selected:
- Libraries included to the Linker:
- Predefined variables CLA_MATH_TABLES_IN_ROM=1 and CLA_C=1 activated in the Linker section.
- *.CMD file without CLA1mathTables section.
Futhermore, I have tried to load the CLA math Table to RAM, without all the ROM configurations, and the error is gone, logically.
What should I do with that warning?
Thanks.
