CCS/TMS320F280049: warning: Data is being written to auto-generated file

Part Number: TMS320F280049
Other Parts Discussed in Thread: SFRA, C2000WARE

Tool/software: Code Composer Studio

Dear C2000 expert,

Currently I'm using sfra example and would like to use hex2000 tool to convert the project.out to project.hex, but there is a warning: Data is being written to auto-generated file occurs, can you please help me know how to fix it?

SFRA example: C:\ti\c2000\C2000Ware_DigitalPower_SDK_2_00_01_00\libraries\sfra\examples

hex2000 commands:

hex2000.exe -i "${ProjName}.out" -o "${ProjName}.hex" -order LS -romwidth 16
hex2000.exe -x "${ProjName}.out" -o "${ProjName}.x0" -order LS -romwidth 16

2 warnings from CCS:

warning: Data is being written to auto-generated file
example1_stb_f28004x_f32_coff.i10
warning: Data is being written to auto-generated file

Hi George,

Thanks for this info. What's your proposal of fixing this warning? Just change the link cmd to allocate all data to PAGE 0 ?

After doing some test, I found that this warning is caused by the rts2800_fpu32_fast_supplement_coff.lib, I have just delete this lib from C2000 linker and comment out all the data or funcations called in this lib, this warning is disapeared. Can you please help me know why the rts2800_fpu32_fast_supplement_coff.lib cause this warning?

Here I attached those 2 projects, one has this warning, the other didn't have this warning. Hope you can reproduce this in your side.

warning ccs project:example1_stb_f28004x_f32_coff_WARNINGS.zip

no warning project:example1_stb_f28004x_f32_coff_NO_WARNINGS.zip

Jack, George,

The RTS fast supplement library is, as would expect, built to output a static library, so its CCS project does not contain any linker cmd file. It has a few tables that are allocated to a section called "FPUMathTables", so the user project's linker cmd file would decide the placement of this section.

Perhaps the user's project in this case allocates this section to Page 1, which is causing the issue on the hex generation step?

Thanks,

Sira

Hi Sira,

Yes, the FPUMathTables are allocated to page 1 in TI's example code. And after moving RAMGS3 to page 0, this warning is gone.

FPUmathTables : > RAMGS3, PAGE = 1

But what my question is that, is it affact the performance if moving the FPUmathTables to page 0? What I cared is that the excution time will get longer.

As I know, in C2000 family, page 0 specifies program memory, page 1 specifies data memory. And I think the FPUMathTables are belongs to data memory. Thanks...

TI__Mastermind 27935 points

Jack,

As long as it stays in the same RAM region, I don't see how or why it will affect cycle count. Plus, if I remember correctly, with the move to EABI, we are moving away from the PAGE concept.

Thanks,

Sira

Mastermind 7160 points

Hi Sira,

Thanks for your support here. If there is no affect on cycle count, why does the MEMORY divide to PAGE 0 and PAGE1 in c2000 family? What's the side effect if I putting all things to PAGE0?

Hope everything is fine with you and your family.

Jack,

Thank you for asking, hope the same for you.

See comment to me from Compiler expert, aligned with my comments.

"My understanding is we no longer need PAGEs (ie since we have unified memory now). And for EABI we actually don’t do anything with the PAGE info."

Thanks,

Sira
