TDA2PXEVM: Edma_utils_autoincrement_test does not work

Hi

Have you done any changes on top of default test APP ? if yes please share the changes along with log.

Thanks

Thanks for your reply.

DMAUtilsLibrary_UserGuide indicates how to build samples, but does not mention how to read it with CCS.
(Error occurs when trying to read the sample with CCS. See image1.)

In order to load it as a CCS project, I used an existing sample program which can be leaded as a CCS project.

I mean that I used  the dsplib sample program whose contents are replaced with edma_utils_autoincrement.

So, the code hasn't changed anything except the include file name.

The edma_utils_autoincrement_1d_test worked well in this way.

I have two questions:

- Is this the right way to load in CCS? If no, please tell me the procedure.

- Is there any other good way to run edma_utils_autoincrement_test?

Hi,

Please refer to the below document.

Chaper 3.7 :vision_sdk/docs/UserGuides/VisionSDK_UserGuide_TDA2px.pdf

Thanks

Hi Gaviraju,

I know the procedure.

What I have asked you this time is that the test program cannot be imported as a CCS project, and even if I port it to a CCS project by myself, it stops working halfway.

Please refer "image 1" shown above.

What is the cause?

Thanks,

Koji

Hi,

Porting all these to a CCS project and getting to work might take significant effort.

I would like to know, why do you prefer the CCS project over gnu make?

 If you looking for a better debugging experience, you really do not need to use CCS project. You can use CCS to debug even after you build the executables via GNU make system (part of VSDK build infrastructure).

Thanks

Hi Gaviraju,

Since the DSP sample was a CCS project, I misunderstood that it needed to be a CCS project.

Hi 

Can you share what changes have you done?

Thanks

Hi Gaviraju,

I tried changing the numerical value of 156-159 line of edma_utils_autoincrement_test.c.
It is described in the following order. (Width, height, inPitch, outPitch)

When I set (1024, 512, 1024, 1024) and (256, 512, 256, 256), "EDMA TEST, PASSED"  was displayed.
On the other hand, when I set (1024, 32, 1024, 1024) and (128, 512, 128, 128), "FAILED !" was displayed.

I feel that it does not work if the product of width and height is small.
So I thought there were some restrictions.

Thanks,

Koji
