Tool/software: TI-RTOS

Hi,

I am using ccs v6.2 with tm4c1294xl launchpad, cc3100bp.

I want to enable both wifi and emac on my device, I success fully connected to wifi and it was working in the same main going to initialize the emac also but when I am calling anything from the EMAC class of tirtos it was not building instead giving an errors

**#10010 errors encountered during linking; "newproject.out" not built

** #10234-D unresolved symbols remain and

error #10234-D: unresolved symbols remain

error #10010: errors encountered during linking; "Kiko_Point.out" not built

makefile:162: recipe for target 'Kiko_Point.out' failed
gmake: *** [Kiko_Point.out] Error 1
gmake: Target 'all' not remade because of errors.

**** Build Finished ****

I has not calling any of wifi init or wifi related functions, if I not call any EMAC class functions it was building and running fine, but I have to use the EMAC_init() of this class to initialize emac. As well I check with tirtos provided example project also all the includes and header used properly.

So, can you help me to resolve these errors.

Thanks,

We have a couple solutions for this. I'll detail them after I get some feedback on one of the solutions later this week.

We don't have official support for running both stacks at the same time on the TM4C129 devices . You can look at this reference design for ideas: www.ti.com/.../TIDM-TM4C129XGATEWAY

Basically you have to use the lower levels of the SL APIs.

Hi ToddMullanix,
Any updates on the one more method of solution as you said it was under test.
We are feeling difficult in this way, I imported a Gateway main application from the given link and it was giving as no rtos configuration .cfg found and while building the wholfSSL I am getting compilation error.

Hi ToddMulanix,

As you suggest I am trying the gateway app "<download directory>\TIDM-TM4C129XGATEWAY_Project_Source\Gateway\TM4C129x", but this is giving me the error : "This project does not contain a buildable RTSC Configuration (.cfg) file. In order for it to build, this project must contain one RTSC Configuration file that is not excluded from build."

If I create new .cfg for the project I was getting error:

ERROR1: #20 identifier "CloudMailbox" is undefined

The same error is repeating for 5 times.

I am not sure is need to make new .cfg for this project to run or not but I had tried and come out with errors.Is this example project needs RTOS or NOT.

Please, expecting your support.

Regards,

Raghu DS

You cannot just add any .cfg file. You need to find the one that was used with the project. It looks like the Gateway_Main_App has a dependency on the ti_rtos_config project. I see that in Properties->Build->Dependencies. Try importing that also.

Hi ToddMullanix,

Thanks for the reply, ".cfg" file for the Gateway is found in the downloaded package.

If I include that, getting errors on build:

As error is saying FLASH and SRAM memory are already been specified I comment out the lines in ".cmd" and tried the build again and getting the errors:

So, it seems to be something as to define in the configuration, don't know and not sure also.
