Modifying the ld file results in a compilation error due to overlapping sections

Hi, developers, I encountered a compilation error with GCC when configuring DTCM as SRAM using S32K312. I haven't made any progress in finding the cause of the error. I referred to the community topic discussion, "How to modify the LD file to use ITCM and DTCM content," but following the manual and the discussion's LD file configuration led to a compilation error. Can anyone help me resolve this issue?

I tried various versions of GCC, such as GCC9.2.0, GCC 10.2.0, GCC 10.3.1, GCC12.2.0。But all resulted in the same error.

IDE: vscode
cmake version: 3.28.1

Re: Modifying the ld file results in a compilation error due to overlapping sections

hi, @lukaszadrapa

thaks your response. i compare the link file you provided. there wasn't much difference.

I searched for a solution and found that the issue lies in the LD file configuration. The attribute "os_globle" was declared in the program but not configured in the LD file, leading to the error. In the LD.pdf documentation on overlapping, I identified this problem.

Hi @DennyZhang

attached is linker file from RTD 4.0.0 which already contains definitions for DTCM. It's working on my side.
