TorizonCore Builder unexpected Exception


i’m trying to generate a customized image and push it to Torizon OTA with torizoncore builder.

I followed the documentation: Signing and Pushing TorizonCore Packages to Torizon Platform Services | Toradex Developer Center

But i always get the following error:

fabian@WS012148:~/tcbworkdir/workdir$ tree

The image is self built using yocto.


Also, out of curiosity, is there a reason why you built a TorizonCore yourself instead of using a pre-built one?

Hi @henrique.tx
Yes, this was the problem.

Thank you.

For some testing i needed the .netcore runtime on the image. Can i achieve this with the build command and the filesystem section in the config with torizoncore-builder?

Hi, @wheeler

Applications on TorizonCore uses containers. Packages dependencies should be handled on the container level.

Take a look here: .NET Core Development and Debugging on Torizon Using Visual Studio Code | Toradex Developer Center

Hi, @wheeler

Have you unpacked your base image? This step is mandatory before you start to customize a TorizonCore image.
