how to build the JPEGDEC demo on C6678L(CCS5.0.3)

Hi Shiqiang,

I've downloaded and imported the project into CCSv5 (5.0.3) and you are right it does look like the 'build variables' and 'include options' JPEG decoder project properties and source file paths are hard-coded to specific CCSv4 paths on the developer's computer. Essentially for this to work you'll have to modify these and make them generic. I'm in the process of trying this and will get back to you with specific steps for a successful port to CCSv5. 

Hi, 

Thanks very much for your detail instructions. I have downed the file your provided and imported to CCS5.0.3, then built successful. I will load it to EVM6678L through JTAG at night and to see if it will work.

I have two more questions when I change the project properties as you said below:

1. where are the environment  variables FRAMEWORK_COMPONENTS_CG_ROOT and  BIOS_CG_ROOT defined? I have checked Properties-> C/C++ Build -> Build variables -> Show system variables, and seen variables such as CG_TOOL_ROOT, but haven't seen the two.

2. When I change the project properties, it says that "Could not write file:Could not write file: E:\TI\TMS320C66x\Codecs\packages\ti\sdo\codecs\jpegdec\App\Client\Build\TestAppDecoder\.project." and the details says "E:\TI\TMS320C66x\Codecs\packages\ti\sdo\codecs\jpegdec\App\Client\Build\TestAppDecoder\.project (access denied.)". I am sure that although I change the authority of all files in the project, the error is always on.

could give some advise on the previous two problems?

Hi Shiqiang,

The variables FRAMEWORK_COMPONENTS_CG_ROOT and BIOS_CG_ROOT get automatically defined when the relevant RTSC packages are selected (which is already done in the project I sent you). You do not need to make any changes to the project properties. The project once imported should build successfully as provided. From your post, it looks like you were able to successfully do that.

Hi Gurnani,

It's right that after I import the project, I build it successfully.

But i just want to learn more to specify CCSv5 settings, so I just do the steps as you listed.

In the steps, I don't understand "• Changed path to source files to a generic one", could you show more details to me?

Thanks anyway.

Shiqiang 

Hi Shiqiang,

The "Changed path to source files to a generic one" refers to the following:

In the zip I've provided, if you right click on any source file, for example, alg_create.c, you'll see that the file location now points to "JPEGDEC_ROOT\Client\Test\Src\alg_create.c," where JPEGDEC_ROOT is defined as JPEGDEC_ROOT=./../../../ in macros.ini. It is generic in the sense that it isn't dependent on an absolute path on any computer. This way when you received the project, you could import and build without making any changes to any paths / environment variables.

hi Gurnani,

I have got it. Thanks.

but when I load the program to EVM6678L and run it, it still have some problems. I posted a new post at http://e2e.ti.com/support/embedded/multimedia_software_codecs/f/356/t/166901.aspx#608513, It may be the problem of the version of CCS, and I'll try more.

Hi, Gurnani,

Thanks for your porting work of c6678 jpeg at ccs5.

And I encounter the same problems about H264 TestAppEncoder demo.

Could you help? 

Hi,

I've followed the steps to import the adapted project. There is no variable errors and such.

However, the linker crashes, and I can't figure out why. I'm using CCS 5.1.1.00031

There is the linker output error:

I don't know the answer to this. Please do not reply to answered posts with new questions. Please write a new post in the Codecs forum. That way your question won't get lost in previous posts, and more experts from the Codec forum will be able to look at this and comment.

Thanks!
