Hi team,

Recently, we met some problems with CCS based MCAL project, which are listed as below.

1. Now I am using QSPI_SBL, and my APP code's cmd file is Ink_r5_am263_CLANG.cmd, My application cannot start normally after the system finishes running SBL. The project and linker files https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/lnk_5F00_r5_5F00_am263_5F00_CLANG.cmdhttps://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/0574.linker.cmdare attached in the link below tidrive.ext.ti.com/.../35cc8a4c-79dd-42b3-aced-4d8e360f0da5

2. All of MCAL-based CCS project will run immediately after load program without resume. But bin build by makefile will not.

    Hi Bruce,

    1. Delete the linker.cmd in your project.
    2. Replace the content of lnk_r5_am263_CLANG.cmd with the below linker content
    3. Rename the lnk_r5_am263_CLANG.cmd as linker.cmd
    4. Clean & build your project and see if it works. I was able to halt at the main with this linker changes.

    I was able to halt at the main after making this change. Seems like the entry point was the major change.

    Thanks,
    G Kowshik

    Hi Kowshik,

    Thanks, Kowshik! It works. In terms of problem1, supplementary information is as follows:

    Firstly, I used the linker file belowhttps://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/lnk_5F00_r5_5F00_am263_5F00_CLANG_2800_1_2900_.cmd, the application cannot start normally after the system finishes running SBL. When I modified the linker file shown as belowhttps://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/linker_2800_1_2900_.cmdhttps://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/lnk_5F00_r5_5F00_am263_5F00_CLANG_2800_2_2900_.cmdthe project can work now. I want to check if I only use Ink_r5_am263_CLANG.cmd but not linker.cmd for CCS project, Is there anything that needs to be modified when the qspi starts? Thanks
