Problems when joining L138_am_poll and gpio projects

Linker command file typically contains Memory map of the device and mapping of sections of your application to the device memory. In addition it can configure stack or link object files so you will need to merge the two linker command files.

Since this is linker command file for the same device I assume that the Memory sections defined in the linker command file will be the same or similar (origin will be the same but length of section may be different). If length is the same then you can leave it to the same value, if they are different set it to the higher value. The map file generated from individual projects should specify how much portion of the section is free to be used.

For Application binary sections compare the two linker command files and if there is some section missing then add it to the command file for the combined project.

Documention of syntax used in Linker command files is part of the compiler documentation under C:\ti\ccsv5\tools\compiler\c6000\cgt_7.x\docs

If the above steps don`t work, please post the two linker commnad files here on the forums , along with the error you see. and we can help you merge it.

Hi Rahul,

I've tried to join both cmd files but I couldn't make it. Could help me with this? These are the cmd files:

I also have problems with the obj files, but first I think we should join the cmd files. All the errors I get on the building process are involved with L138_LCDK_aic3106init.obj

Thanks a lot,

Miguel.

Hi Miguel,

Please find the combined linker.cmd file below:-

Explanation:

The second linker command file's section directives are into the L2 RAM.

For both the projects you can combinedly use the DDR2 and add  .EXT_RAM  into SECTIONS.

As the stack size for the first linker file is being greater as 0x10000 than the stack size given at the second file, you can choose the 0x10000 and not the 0x800.

The heap size is same for both!.

Hi Miguel,

Is it possible to upload your project with all the source ?

Regards,

Shankari

Hi,

Which destination export should I select for upload the project?

Regards,

Miguel.

Hi,

This error seems linking error,

What are your projects trying to combine?

I have doubt on your project linking.

Provide your exact libraries name in linking options (ex: drivers.lib, platform.lib)

Share your screen shot of  linker options from CCS "properties"

Hi,

This is the screen shot of my linker file search path:

Regards,

Miguel.

Linker - file search path:

Hi,

Attachment is not available,

I think it is missed.

Please check it and attach the same.

Sorry. Linker - file search path:

Thanks,

Miguel.

Hi,

Try to give the exact location path of libraries than using "../../"

I'm able to build & run without any issues the combinations of SYSBIOS code and starterware code by proper adding the include files and linking.

Ex:

Attach your project folder or send your project to my email ID (x0213399@ti.com)

Also, Provide your installation location too.

The paths "../../" appeared when I opened the original gpio project example. These paths work fine when I build only the GPIO part of the project, if I add the audio codec then I have those errors.

I have sent you an email with the info you asked me for. If you need anything else just tell me.

Thanks,

Miguel.

Hi,

I got your files, Thanks.

I have sent modified project and update your results here,

I have given exact location path for libraries.

We will check tomorrow.

Hi Miguel,

I'm able to build your project which is combined gpio and audio projects.

The following issues were identified in your project build.

1) "evmomapl138_bsl.lib" libraries were compiled in "COFF" format, So you are getting linker error when you trying to build with combined GPIO & audio project with "ELF" format.

2) We can't build "evmomapl138_bsl.lib" library in ELF format since we don't have source code of that instead we need to compile the our combined format in "COFF" format.

3) We have to compile the "drivers.lib" and "platform.lib" libraries in COFF format also, since those libraries were compiled in ELF format already.

I'm not sure about the functionality because "audio" project is from "EVM" board and "gpio" project is from "LCDK"

I will send your modified project through email.

Note:

I received the above shaded error for "drivers.lib" and "platform.lib" which is required to build "gpio" project but the above "system_config.lib" is not required for your project, that why we didn't receive any error.

How did you change the format of the libraries?

Ok! It worked for me! I just had to choose the COFF format!

Hi Miguel,

Sounds good.

Thanks for your update.

Note:

Titus said:

I'm not sure about the functionality because "audio" project is from "EVM" board and "gpio" project is from "LCDK"

As I said early, Please try to run the binary, If any issues, Debug your code through emulator.

How do I run the binary? It seems like the gpio project isn't working. But I don't get any error...

Hi,

Do you have emulator with you?

If yes, Debug your project through CCS (load option & click start button to run).

If not, It is difficult to find out problem.

I have the XDS100v2 emulator connected to my board. Which steps do I have to follow for debugging throgh the emulator?

Hi,

You can use "Step into" or "Step over" options to debug.

Check that whether the code flow was correct and behaving as you expected.

http://processors.wiki.ti.com/index.php/DSS_-_Launching_CCS_from_DSS#Debugging_steps_for_CCSv5.2_and_greater_.28including_CCSv6.29

http://processors.wiki.ti.com/index.php/Sitara_Linux_SDK_CCS_GDB_Setup#Running_the.C2.A0Debug_Session

Hi Titus,

I've discovered where the problem is. On the sentence from int main function:

  /* The Local PSC number for GPIO is 3. GPIO belongs to PSC1 module.*/
      PSCModuleControl(SOC_PSC_1_REGS, HW_PSC_GPIO, PSC_POWERDOMAIN_ALWAYS_ON,
               PSC_MDCTL_NEXT_ENABLE);

The program gets into psc.c and it stays indefinitly on this while loop:

    if (timeout != 0)
    {
        timeout = 0xFFFFFF;
        status = flags & PSC_MDCTL_NEXT;
        do {
            timeout--;
        } while(timeout &&
                (HWREG(baseAdd + PSC_MDSTAT(moduleId)) & PSC_MDSTAT_STATE) != status);
    }

Each time I click on Step Into, the value of timeout decreases, but its initial value is very high. After that loop, I get into another loop on evmomapl138.c and I can't get out of it:

while (CHKBIT(psc->MDSTAT[in_module], MASK_STATE) != in_next_state) {}

For what is that timeout and why am I getting stuck in the second while loop? Do you have any idea of why this is happening?

Thanks.
