CCS/TMS320F28035: LUT in flash

S.Ibarra

Part Number: TMS320F28035

Tool/software: Code Composer Studio

Hi, All

After several weeks of work I managed, with the help of the forum, to define a flash memory section in the .cmd file and create a table in the main .c file. But when I compile the program and started debugging, in the flash memory window I see that it does not contain the data I saved.

I need the LUT to generate a sinusoidal signal, directing the table.

I am using the experimental kit for the microcontroller TMS320F28035 and CCS V7.0

Thank you very much for your help

Can you provide details on your memory section and how you're linking your LUT to the section? Is your LUT defined as "const"?

Best regards

Hi, Christopher

I need to generate a LUT to produce a sinusoidal signal for a three phase inverter. The great quatity of information of microcontroller and CCS, and... provocs in my confuse. Do you can give me advices about the way to learn the tools for microcotrollers TI?
I did the C2000 pipccolo workshop, revision 2.1 from dcecmber 2010, with Experimenter kit (TMS320F28035).

I send screenviews in three files

Thanks a lot.

Your linker and pragma use look right. Change your array from "unsigned long" to "const unsigned long". This should fix your issue.
