Hello @HafizUsman, Good Day!
Thank you very much for your interest in our products.
Based on the error log that you shared, it appears that the build process is failing to find some functions that are defined in the "ndeft2t.c" and "ndeft2t.h" files. In order to get past this error, you would need to create a link to said modules in your application project.
You may find a detailed description of that process in section 4.1.4 "Mods"' of the UM11153 document available in the ''SDK Folder/docs/UM11153''.
My best regards,
Daniel.
