Hi Manjunath K M,

About this question, I have answered a lot of times before in the community.

Please refer to this post:

I wonder how to get CAN to work with KDS's Processor Expert?

I already share the working project, and the test result.

Please use that project.

Wish it helps you!

Have a great day,
Kerry

Thanks Kerry for your reply.

I am trying to use the workspace that you have shared, but i am not able build due to include path,

In the build path, i am getting a message that, "Orphaned configuration. No base extension cfg exists for ilg.gnuarmeclipse.managedbuild.cross.config.elf.debug.715618587", It's not allowing me to change the path as well.

I have seen this message earlier also, when i was tried to use some of the sample code, but i was end up with not getting solution to eliminate this issue,

Can you please explain me why i am getting this message.

Thanks and regards,

Manjunath

Hi Manjunath K M,

When you open the project, don't select the workspace path to the project path, please select the other path, not the project path directly.

Then try it again, if you still have problem, please also attached your message picture.

Have a great day,
Kerry

Hi Manjunath K M,

Why do you want to modify the include path?

It should be work directly on your side.

If you want to modify it, you can click the edit.

This is the picture on my side:

If you are still not OK, Please check your KDS version, use the latest KDS IDE.

Have a great day,
Kerry

Thanks for your time Kerry,

I am using S32 IDE to build the project, and when i am trying to build the project, it was showing error message that path cannot be found.

Hi Manjunath K M,

My project is the KDS project, not the S32 IDE project, that's why you can't make it work.

You can go to this link:

www.nxp.com/kds

Download and install the KDS, then open my project.

Wish it helps you!

Have a great day,
Kerry

Hi Kerry,

I could not get a chance to download KDS IDE. I was unable to download this IDE.

I worked with my code and made it working now. I Had a issue with MCU clock settings. After changing the clock settings, both RX and TX are functioning properly.

Thank you for you help
