Hi jmv,
In order to get rid of linker warnings it might help to recompile all libraries related to CFv1.
Open the library projects that refer to the libraries you are using in your project e.g.:
"c:\Program Files\Freescale\CodeWarrior for Microcontrollers V6.1\ColdFire_Support\Runtime\Runtime_ColdFire\Projects\MSL_RuntimeCF.v1.mcp"
and/or
"c:\Program Files\Freescale\CodeWarrior for Microcontrollers V6.1\ColdFire_Support\msl\MSL_C\MSL_ColdFire\Project\MSL_C.CF.v1.mcp"
and build them all.
Ensure that your project paths refers to updated libs.
