PROCESSOR-SDK-AM57X: Building and running IPC examples

Part Number: PROCESSOR-SDK-AM57X
Other Parts Discussed in Thread: TMDXIDK5718, AM5718

Target platform: TMDXIDK5718 (am5718 evm)

By following this video (https://www.ti.com/video/series/am57x-sitara-processors-training-series.html?keyMatch=INTRODUCTION%20TO%20IPC) and making a few minor changes to get the paths correct, I completed the following successfully:

make ipc_bios

make ti-ipc-linux

make ti-ipc-examples

It doesn't appear that I should have any trouble with the remaining steps in the video. However, I have a question as to how I need to merge or capture these changes in Yocto build. It seems that 'make ti-ipc-linux' step generates changes to the kernel and rootfs content. Could you describe the corresponding Yocto build steps I need to follow?

Hi Peter,

To place the changes into an image built by Yocto, you would need to add the changes made by the scipts/makefiles to a new Yocto layer/recipe, and place that on top of the existing Yocto image/recipe you are trying to build.

You can look at Yocto's documentation for instructions on how to create a new recipe. Forewarning, I don't think this would trivial.

Best,
Jared

'make ti-ipc-linux' builds ipc libraries. How do these get added to the target linux image if not through yocto? That step is not shown in the video.

Hi Peter,

Can you try appending "_install" to your make commands?

Best,
