Why do I receive an error when building code for a processor-in-the-loop (PIL) cosimulation with Embedded Target for Motorola MPC555 2.0 (R14)?

My model includes a noninlined S-function, for which a TLC file for the S-function is absent. When building code for a processor-in-the-loop (PIL) cosimulation using Embedded Target for Motorola MPC555 2.0 (R14), the following error is returned:

We have verified that there is a bug in Embedded Target for Motorola MPC555 2.0 (R14) in the way that a PIL cosimulation handles a non-inlined S-function.

To work around this issue, use inlined S-functions in your model. Information that explains how to inline an S-function is provided in the Real-Time Workshop 6.0 (R14) documentation, accessed by typing the following at the MATLAB prompt:
