C6670 FFTC Simple test Project

Hari..
Intellectual 605 points

Hi,

I am trying to understand the FFT Coprocessor on 6670(EVM). So I started with the FFTC simple test example project from the below path.

C:\ti\pdk_C6670_1_1_2_6\packages\ti\drv\exampleProjects\FFTC_Simple_testProject

Procedure :

1. EVM is in No Boot mode.

2. Compiled the project and loaded the same output file to all the cores.

3. Grouped all the cores and executed the group.

I don't see any output on the console and the program seems to be running forever.  I did not do any modifications to the example code. Is there any specific procedure I need to follow to execute this project ? Can I get some help in executing this project ?

Thanks

Hari

    Hi Hari,

    Make sure to initialize the core with gel file while connecting the core0 before loading and running the test application. Many customers able to run without any issue. Please refer below thread,

    Please refer the readme.txt file for the test and example project usage in below path.

    PATH: ..\ti\pdk_C6670_1_1_2_6\packages\ti\drv\fftc\test & ..\ti\pdk_C6670_1_1_2_6\packages\ti\drv\fftc\example\multicore

    Thank you.

    Thank you Raja. I had some issues with my imported project.  When  I delete the project from CCS and re-import, the test runs fine.  

    Test runs to the end successfully with 2 of the tests failed. Fftc_clearErrorIntEnableReg() test failed for testing instance A and B. Here are the results. Is this the expected test result ?

    Hi Hari,
    I have checked with FFTC expert and he confirmed that there is a bug in the example. I will file an IR to resolve it next release.
    Thank you.
