CCS/EK-TM4C1294XL: Storing and accessing medium sized data pattern in flash?

Ja Hv

Tool/software: Code Composer Studio

I would like to store a number of fixed data patterns somewhere in the processors memory. We are talking about 16-20 kB total so EEPROM (6 kB) is not the way forward.

The patterns are fixed, and I have them in binary files. Storage in flash would be nice, so I would not have to upload every time started.

But how to do it in CCS?

Getting the patterns there and how to access them?

Hi,

Please refer to using the DATA_SECTION Pragma Directives section in the TI C compiler user's guide. Below is an excerpt.

See Compiler/MSP432P401R: Loading a binary object into flash during programing to be read by NVS later for an example for a MSP432 using the TI compiler of how to get the linker to place the contents of a binary file into the .const section in flash during the build.

The technique should be usable on a : EK-TM4C1294XL.
