CCS/TMS320F28379S: Allocating many functions to RAM

Hideaki Nambu

Part Number: TMS320F28379S

Tool/software: Code Composer Studio

Hello,

Could you please advise how to put the ramfunc attribute to tens of C functions? Or how to set the default location of the C functions to RAM?

My customer hesitate to put the line "__attribute__((ramfunc))" to the head of the many functions.

We have studied the C compiler manual and already succeeded to set it to several functions.

My idea would be the following, but TI would have a better solutions:

[My idea]

# Define the --ramfunc option. Or allocate the .text to RAM.

# allocate some programs like c_int00 and main(), and InitSysCtrl() to flash.

Collect those functions together into one or two source files, then add the build option --ramfunc to only those source files, and not the rest. In a CCS project, use the File Specific Options feature.

Thanks and regards,
