Describe the solution you'd like
Starting with PR #198 the schema.c file is generated by a Python script from a JSON specification. This scripts runs during a Linux build, but is not yet set up to run when the build is made via Code Composer Studio (CCS). Users working with CCS must run the script manually prior to the build. This process should be automated for CCS users.
