What does this linker remark mean?

remark #10191-D:
object ".printf" is not allocated, but is being placed as part of allocated
object "GROUP_2"

I'm using DSP/BIOS 5.41.11.38

with tools version 4.3.9

compiled for generic C55xx Device

I seem to recall getting the remark even before I added a secondary hand written linker command file. Here's part of it:

SECTIONS {
    /* lines omitted */

    GROUP {
    /* lines omitted */
        .const: block(0x20000) {}
        .printf (COPY): {}
     /* lines omitted */
    } > SDRAM PAGE 0
}

Here's part of my .tcf script

utils.loadPlatform("ti.platforms.evm5509A");

/* The following DSP/BIOS Features are enabled. */
bios.enableRealTimeAnalysis(prog);
bios.enableRtdx(prog);
bios.enableTskManager(prog);
// lines omitted

// !GRAPHICAL_CONFIG_TOOL_SCRIPT_INSERT_POINT!

prog.gen();

Hi John --

Can you please try removing this .printf section from your secondary linker .cmd file? I'm pretty sure that this gets added by BIOS to the primary .cmd file. And having this section in both must be causing some problem. If that doesn't help, can you please make a small example and zip it up and attach it to this forum?

Thanks,
-Karl-

If I remove the .printf section from the secondary linker .cmd file I get

warning #10247-D: creating output section ".printf" without a SECTIONS
specification

You are correct that by default tconf generates a .printf section in the primary .cmd file, but because I have modified the .tcf script to tconf, there is no .printf section in the generated primary .cmd file. I copied part of the primary .cmd file to the secondary .cmd file, then set

bios.MEM.USERCOMMANDFILE = 1;

and reran tconf

After doing that there is no .printf section in the generated.cmd file.

My first attempt to create a small example has failed. If you have no further comment I'll reopen this discussion when I have more time to put into the example.

It turns out to be trivially easy to reproduce this: just turn on remarks in a default DSP/BIOS C55x project, in other words:

With eclipse Version: 5.1.0.09000 and with the TI 4.3.9 compiler installed

create new CCS Project
    check Compiler version TI v4.3.9
create new DSP/BIOS Configuration
    choose ti.platforms.evm5509A
    close graphical editor
    Do you wish to enable RTSC support etc.
        yes
Open the new project's build options from project explorer
    C5500 Compiler
        Diagnostic options Issue remarks tick
        Runtime Model Options Specify memory model large
    C5500 Linker
        File Search Path Include library file etc. "libc.a" delete
Build the project

Should get:

"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C5500 Code Generation Tools 4.3.9/bin/cl55" -g --display_error_number --issue_remarks --diag_warning=225 --ptrdiff_size=16 --memory_model=large -z -m"test2.map" --warn_sections -i"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C5500 Code Generation Tools 4.3.9/lib" -i"C:/Program Files/Texas Instruments/ccsv4/tools/compiler/C5500 Code Generation Tools 4.3.9/include" -i"C:/ti/bios_5_41_11_38/packages/ti/rtdx/lib/c5500" -i"C:/ti/bios_5_41_11_38/packages/ti/bios/lib" --reread_libs --rom_model -o "test2.out" -l"./test2cfg.cmd" "./test2cfg_c.obj" "./test2cfg.obj" "./main.obj"
<Linking>
"./test2cfg.cmd", line 251: remark #10191-D: object ".printf" is not allocated,
but is being placed as part of allocated object "GROUP_1"

Should I take this to the DSP/BIOS forum?

Sorry, I meant should I take it to the TI compiler forum?
