Linking error when building IPC SRIO example project

Hi,

I have successfully import and build the project. See my screen below:

I try to build your attached project, but srioChipToChipProducer_c6678\common folder is empty on your zip file.

Have you copy the MCSDK example to your work space? Better to import the example project from default MCSDK path, don't copy to your work space.

Thanks,

Hi,

It looks like you are selecting the option, "Copy projects into work-space", when you are importing. The linking error you see in the first case is caused by this because CCS could not copy the 'common' folder due to it being defined with a variable in its path (if you right click on it and select properties, you can see it defined as ${PARENT-1-PROJECT_LOC}\common).

Follow the below two ways you may try to solve this error:

1) Import without copying to your work-space and work directly on the directory

2) Hard copy the "common" folder into your current project location and change the common folder path in project properties. see below image, after this changes i able to built your attached project.

Thanks,

Hi Ganapathi,

Thanks it works, I don't know why the consumer project imports those files but the producer doesn't...

I just built the 2 projects and use the ci2evmboc breakout board to connect the 2 boards and ran the 2 applications on both sides.

On the producer side, it prints out:

Hi Ganapathi,

Yes that's exactly what I followed from the readme file. And the result was as I posted. I noticed on both producer and consumer side, it prints out :

[C66xx_0] Port 0 did not initialize

Port 1 did not initialize

Port 2 did not initialize

Port 3 did not initialize

Could it be the reason that the example fails?

Thanks,
Shang

Hi,

I have followed the same steps to tested the example on C6678 EVM. it is working fine, see the attached test log file.

I think board connection issue on your test setup. Please see the below wiki link to confirm your connection setup

Thanks,

Hi Ganapathi,

Would you please upload the .out files (or better, the project) that you successfully run? So that I can locate where the problem is.

Thanks,
Shang

Hi,

Please find my attached .out file.SRIO_binary.zip

Thanks,

Hi Ganapathi,

I just tried your binary files and here is the log from producer side:

[C66xx_0] ti.sdo.ipc.MessageQ: line 441: assertion failure: A_invalidQueueId: Invalid queueId is used

xdc.runtime.Error.raise: terminating execution

There is an error message and then that core just stops running. The consumer side is basically still  waiting for packets. I've looked into invalidID issues on the website and most of them are software config issues. Given that I'm using your compiled binaries, I really couldn't figure out where the problem is.. 

Thanks,

Shang

Hi Ganapathi,

So I'm using 2 computers to launch 2 separate sessions on 2 boards respectively. Here are the screenshots right before I click "run" button. Gel files are loaded to each core and global setups have been done.

Thanks,

Shang

Hi,

Refer below wiki link to configure two emulator on single target configuration file and load/run the both EVM binaries in single computer CCS.

See below my CCS target configuration file screen shot for your reference:

Thanks,

Hi,

i shared the the above screen shot only for your reference.

In my setup, one EVM have Blackhawk XDS560v2 Mezzanine Card. I configured one on-board xds100v1 emulator and Blackhawk XDS560v2 emulator on my target configuration file. I used this .ccxml file for testing. Refer my .ccxml file. https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/Two_5F00_C6678.ccxml

Thanks,
