DEY-5.0-r4 CCMP25 populate_sdk fails

I am unable to build the CCMP25 toolchain for DEY-5.0. Anyone else having this problem?

To reproduce the error:

I expected the populate_sdk command to complete successfully and output a dey-toolchain-ccmp25-dvk-5.0-r4.sh which I could give to my team to cross-compile against.

In reality, I see the following failure:

Originally, I thought this was a problem with my custom build, but as shown above it easily reproduces using the official DEY-5.0 container with no local changes to dey-image-webkit.

Any ideas?

We recommend using the dey-toolchain image type to generate SDKs:

bitbake -c populate_sdk dey-toolchain

This is a general-purpose SDK, combining most of the packages needed for all of our image types (qt, lvgl, webkit…). We used to build separate SDKs per image type, but we changed this in DEY 5.0 in favor of a single SDK per platform.

In the meantime, we’re investigating the error. It’s reproducible when building an SDK for images that contain the mp1/mp2 machine learning packages. dey-image-webkit on the ccmp25 happens to be one of the only images where this happens by default.

If you really need the machine learning packages in your SDK, you can fix the issue by manually adding onnxruntime to your image and re-building the SDK. To do so, add the following line to your project’s conf/local.conf file:

IMAGE_INSTALL:append = " onnxruntime"

Otherwise, if the machine learning packages aren’t essential, then dey-toolchain is the way to go.

Thank you very much. Adding onnxruntime to local.conf does fix the dey-image-webkit SDK build. I appreciate you finding a work-around and replying to my question.

This recommendation is hard to find in the DEY 5.0 documentation (if it exists at all). It’s nice that it’ll show up in a forum search now, but if anyone on the Digi team has a chance to update their docs with this information it would be really helpful for future users.

I was able to build the dey-toolchain target as well and my application successfully cross-compiles against it.

I was also surprised to see that dey-toolchain wasn’t mentioned anywhere in the documentation. I’ll create a ticket to see what the team can do about that.
