Part Number: AM5746

Tool/software: TI-RTOS

Hello, TI Experts,

Our customer sent us a question about AM574x linker command file (.lds) with PROCESSOR-SDK-RTOS-AM57X.

They would like to assign .bss section to LOAD_RAM2（0ｘ91600000).

So they tried to add to create .lds file and build including xxx.cfg file like attached pdf.

(please refer attached pdf)

But they said ".bss seems to be assigned to 0x8000000".

Question:

Could you tell us how to realize to assign .bss section to LOAD_RAM2（0ｘ91600000)?

Hi,

Thank you very much for your prompt reply.

I really appreciate your help.

From the E2E-thread which you guided, our understanding is below;

- Recommended way is add "sectMap" statement to cfg file.

And in our case, it seems to be success to assign .bss section to LOAD_RAM2 like attached pdf.

If you have any comment, please tell us.

Best regards,
