AAC-LC decoder linker errors

Hi,

I'm adding support of AAC-LC decoder into my application.

The application runs on C6486 (6 cores tomahawk).

I'm using Code Generation tools 7.2.3 without sys bios and with custom built makefile.

AAC decoder for C64x+ version 01.30.03 that was just downloaded from TI site

When I add this library to the linker, I get a lot of warnings:

I saw that there are many rellocation errors between different symbols of the aac decoder library as well as between aac lib and rts library.

I don't know how to fix it and why actually it happens.

I tried to put all aac library functions into the same group in link command like it was done in the sample application, but it didn't help.

Thanks,

Hi Oleg,

This version of AAC-Decoder was actually built with cgtools 6.0.8.

If you are using CCS3.2 or 3.3, there is one option in Build option to change the memory model. Please change the memory model to far and try to build again.

This should resove the issue.

Hi Ram,

Thank you for your quick reply

I tried to add compilation parameters (I don't work with code composer, I work with a makefile that I built):

--mem_model:data=far --mem_model:const=far and it didn't help.

Anyway I don't understand how can it actually change something if the memory model is a compiler parameter and not linker, and the problematic library is already compiled without this flag.

Is there a newer version of C64x+ AAC LC decoder that fixes this problem? (I need COFF library)

In the past I used many TI codecs like AAC LC encoder, H.264 encoder and decoder, MPEG-4 and no one of these libraries caused such a problem. What's the difference with this library?

Thanks,

Oleg

Can anyone help me with this?

It still does not work

Hi Oleg,

AAC-Decoder is built with cg tools 6.0.8. The problem may occur with linker command file when enough memory space is not allocated for the .text section. I am able to reproduce the same kind of linker errors when ROM memory's length is decreased. so, allocating more memory space for the .text section should resolve this issue.

Hi Deepthi,

I'm using C6486 (C6472) tomahawk DSP. I don't use any ROM memories there. All .text sections are placed in external DDR. I tried to free additional memory there (several megabytes) and it didn't help.

Is there something wrong with what I'm doing?

Thanks,

Oleg

Hi Oleg,

Is the codec build with cgtools 6.0.8? If not, can you please try to build it with the same version?

Hi Deepthi,

The codec is indeed built with cgtools 6.0.8 according to documentation. But I can't build it since I don't have a source code.

Can someone do it for me or give me the source code? I use cgtools version 7.2.3 in my project.

Thanks,

Oleg

Hi Oleg,

Is it possible to use cgtools v6.0.8 in your application to link this codec in your project? This codec has been tested with cgtools 6.0.8 and works fine.

Please let us know the behaviour.
