The ABI in RVCT v3.1 is different to that in RVCT v1.2. Therefore, legacy RVCT v1.2 objects and libraries are not directly compatible with RVCT v3.1.
See ABI for the ARM Architecture compliance in the Libraries Guide, and the section on compatibility with legacy objects and libraries in RealView Compilation Tools Essentials Guide for more information.
