Tool/software: Code Composer Studio

Hi

This is like the older post that used version TivaWare_C_Series-2.1.2.111 of which I have applied the fixes

from that post but still have the same build error that changing to PortYIELD fixed with 2.1.2.111

vPortYield doe not work either,  I can not find the def of the function

unresolved symbol PortYIELD, first referenced in ./serial_task.obj     enet_s2e                                     C/C++ Problem  
gmake: Target 'all' not remade because of errors.                                  enet_s2e                                     C/C++ Problem
