Hi,

How to generate *.txt with compiler V18 and other versions?

We tried

"${CG_TOOL_HEX}" --ti_txt "${BuildArtifactFileName}" -o "${BuildArtifactFileBaseName}.txt" -order MS -romwidth 32

It works when compiler with RAM cmd, but not with Flash cmd. The error is like:

warning: section Example_2803xECanBack2Back.out(ramfuncs) at 07e0000h falls in
unconfigured memory (skipped)
warning: section Example_2803xECanBack2Back.out(.text) at 07ec000h falls in
unconfigured memory (skipped)
warning: section Example_2803xECanBack2Back.out(.econst) at 07ecccch falls in

unconfigured memory (skipped)
warning: section Example_2803xECanBack2Back.out(codestart) at 07effech falls in
unconfigured memory (skipped)

Actually, these are not used in the application.

Please search the C28x assembly tools manual for the sub-chapter titled TI-TXT Hex Format.

Thanks and regards,

George,

We tried to re-edit cmd file with something like: FLASH: origin=0x7e000000, length=0x2000.

The original is: FLASH: origin=0x3f000000, length=0x1000

But it doesn't work, with the same error.

What is lost?

Thanks a lot.

Br, Jordan

I apologize for failing to notice that, in your first post, you do not use a hex utility command file. Thus you need to ...

Add a hex utility command file to the project
Specify a ROMS directive in that hex utility command file
The addresses and lengths in the ROMS directive are double what they are in the linker command file

Do not modify the linker command file.

Please see this forum thread. It is not the exact same situation. But it is similar in that a hex utility command file is added to the project to generate a TI-TXT format hex file.

Thanks and regards,

-George
