The warning of ndk example!

Usually this message happens when the linker command file does not specify where to place the <my section> section. To eliminate the warning add a line to your linker command file which specifies where to place the section inside the SECTIONS command.

If the output section was named .template, the linker command file might look like:

   .template > ISRAM

Specifically, if the message refers to the section $build.attributes, the warning should really not be generated for that section. It is meaningless for that section because that section is not allocated in memory. Some versions of the linker have this bug where the warning is generated for the $build.attributes section, however it should not cause any issues and can be afely ignored.

So you can ignore the warning or update your CGT:

SECTIONS
{
....
   .YNsection  > external_ram    
}

and to avoid re-write on my data, I limited the memory range for my 'section'

MEMORY
{
...
   external_ram:    ORIGIN = 0xC5000000  LENGTH = 0x03000000
...
}

But I still receiving a warning:
creating output section " YNsection " without a SECTIONS specification        evmomapl138_test_touch    line 0    1345670764339    8904

It seems that this warning doesn't change anything but I wander why it happens.

Hi Jacob,

Did you put "MEMORY" before or after "SECTIONS" in your linker command file?

Hi Mariana, I put it before. The complete file looks like this.
This is a code from code examples of ZOOM kit, I'm just adding some things to it.

MEMORY
{
   dsp_l2_ram:      ORIGIN = 0x11800000  LENGTH = 0x00040000
   shared_ram:      ORIGIN = 0x80000000  LENGTH = 0x00020000
   external_ram:    ORIGIN = 0xC5000000  LENGTH = 0x03000000
   arm_local_ram:   ORIGIN = 0xFFFF0000  LENGTH = 0x00002000
}

SECTIONS
{
   .text       > shared_ram
   .const      > shared_ram
   .bss        > shared_ram
   .far        > shared_ram
   .switch     > shared_ram
   .stack      > shared_ram
   .data       > shared_ram
   .cinit      > shared_ram
   .sysmem     > shared_ram
   .cio        > shared_ram
   .YNsection  > external_ram    
}

Hi Jacob,

I just tried the same thing you did and I did not get an error. What are you putting in the .YNsection section? Does it fitinthe size specified?

Mariana, I put this:

#pragma DATA_SECTION ( YN , " YNsection ");
const float YN[]={
    #include "YN.txt"
};

Mariana, it helped but the warning did not go away at first. I also had to eliminate the spaces in " .YNsection " to ".YNsection" and now no warnings present.
Thank you very much.

Jacob.

Hi Jacob,

Yes, the name of the section has to match exactly in the command file and in the source file. I am glad you got it working!
