How to use the static library generated by NanoEdge AI Studio in the ISPU template
Hi!
I have generated an n-Class Classification static library with NanoEdge AI Studio using data from ISM330ISN. I want to use this library in the ISPU template project that comes with X-CUBE-ISPU (X-CUBE-ISPU\1.1.0\Ispu\ism330is_lsm6dso16is\template\ispu). I have pasted the .h files (NanoEdgeAI.h and knowledge.h) and the static library (libneai.a) in the ispu_utils folder and have linked the static library by going to Properties > C/C++ Build > Settings > Tool Settings > GNU STRED Cross C Linker > Libraries and inserting the following information:
But after hitting "Apply", "Rebuild Index" and "Apply and Close", when I try to build the project, I get the following errors:

Information that may be relevant (or not):
In the "Deployment" step, in NanoEdge AI Studio, I have already tried to generate the library checking and unchecking the "Float abi" compilation flags. I have not checked other options. If I don't link the library, I can successfully build the project.
I have used the same template to follow along this video tutorial from STMicroelectronics channel and everything went well.
I have already tried to use double quotes around the library name and the result was the same. I have already tried to append ".a" to the library name, and as a result, the library could not be found.
