Hi,
We apologize for the problems you are having. We understand that the guide/project you are using is outdated at this moment, and that still we have it published in our site, we apologize.
Seems to be that the general problem is that the example was created using RTD v1.0.0 while S32DS is taking your RTD v3.0.2. Did you install RTD v1.0.0 prior to importing the project? If not, the project automatically took the RTD version you had installed.
Even after you installed RTD v1.0.0, if the project took RTD v3.0.2 by default, you need to delete the project and import it again. You need both RTD/LLCE for this project to work, do you also have an LLCE version that works with RTD v1.0.0?
If you already have RTD v3.0.2 with LLCE v1.0.4, we can recommend using the available examples by clicking under S32DS:

Then, under the new window, searching by LLCE as shown below:

There is a known issue under LLCE v1.0.4, where the LLCE_BIN_DIR linked resource is linked incorrectly.

You need to follow "Project > Properties > Resource > Linked Resources", click the LLCE_BIN_DIR resource:

And modify it to be linked to the correct installation folder of LLCE, which for our specific case is the following:

After this, you can proceed to update the code under config tools. We recommend reading the "description.txt" file attached to the project, since the instructions to be able to run the project are provided in there.
Please, let us know.
