How to link "FS$$DIV" asm function (from FPU_FastRTS) in RAM?

Alexander Mazalov said:

I use Delfino-F28335 microcontroller. And I need to make float point division execution time more faster. Now "FS$DIV" (from rts2800_fpu32_fast_supplement.lib) executes from FLASH because I use "F28335.cmd" file, and I want to link "FS$DIV" function in RAM.  Is it possible?

Any body can help me? Thanks.

Alexander,

This post describes how to place library members within output sections:

In particular

• Running an Application from Flash (spra958)

and

• Copying Compiler Sections from Flash to RAM on the TMS320F28xxx DSCs (spraau8)

There is also a flash example in controlSUITE (www.ti.com/controlSUITE) under device_support for 2833x (look in the examples directory for one called flash).
