C6678 Openmp Helloworld Example Compilation Error

Hi,

Thank you very much for the note. 

I downloaded the 7.4.0B2 compiler and successfully compiled the code with the following two warnings:

#10247-D creating output section ".TI.tls_init" without a SECTIONS specification HelloWorld_example

#10247-D creating output section ".TI.tls" without a SECTIONS specification HelloWorld_example

Then I tried to execute the program on my C6678 evm but I have the following error outputs:

[C66xx_0] Hello World from thread = 0
[C66xx_0] Number of threads = 8
[C66xx_1] Hello World from thread = 1

Would you please let me know how to fix this problem? Thank you very much.

Zheng,

Could you please try the following:

1. In CCS, go to View-->Target Configurations. Double click on your Target Configuration for the 6678 EVM. As the snapshot below shows, now select C66x_0, and in the "initialization script" path point to the evmc6678l.gel file that is located in your CCSv5 installation directory at 'ccsv5\ccs_base\emulation\boards\evmc6678l\gel\evmc6678l.gel'

2. Repeat Step 1 for all the cores

3. Power cycle the EVM

4. Right-click on your target configuration and click on "Launch selected configuration." This should bring up your Debug view.

5. Connect to all the cores, load the .out files on all cores and run all cores.

If you plan to re-run the example, always ensure that you do a "System Reset" on Core 0, a" CPU Reset" on Cores 1-7, followed by running the "Global_Default_Setup" script on Core 0, and only then load and run the program.

Apart from the above suggestion from Uday, there is one more thing.

Looks like code is getting corrupted.  Where are you loading your executable ?

HI Varada,

I loaded the executable to my board though the USB cable.

P.S. I can not reproduce the error now. The example is executed correctly.

Hi ,

  I  download 7.4.0B2 code generation tools  to compile "helloworld_example" project, but  when i build the project and  i have following errors:

Can you please try with Compiler cgtools version 7.4.1, available at

https://www-a.ti.com/downloads/sds_support/TICodegenerationTools/download.htm

Hope this resolves.

Hi,

I am trying to test some of the examples included in the CCS/MCSDK installation. I have been able to compile the openmp hello world application. But when I load the compiled program to the board and run, no print statements are displayed in the console.

I am using the following tool versions:

compiler: 7.4.1, IPC: 1.24.3.32, PDK: 1.1.0.3, OpenMP: 1.1.2.06, SYS/BIOS: 6.33.5.4.6, MCSDK: 2.01.00.03

Thanks.

Are you seeing printf's from Core 0? There is a defect with the current release due to which only printf's from the master core show up on the console. Any printf's from worker cores are dropped. We are working on fixing this for the next release.

Ajay

A workaround for the defect Ajay mentioned seems to exist at http://processors.wiki.ti.com/index.php/OpenMP_on_C6000#Project_Modifications

Thank Ajay and Uday,

I am able to run the code now. I'm getting the following message though:

Thanks.

Uday's suggestion to uncheck the box that says "On a program load or restart," for all the cores fixed this. Thanks.
