Implementation of "Modbus TCP" on Blackfin VDK + lwIP

I've been looking for a "Modbus TCP" implementation inside an application working with BF537 + VDK + lwIP.

I found that seems exactly what I need. They say this library support a generic lwIP port.

Has anybody successfully tried this library with Blackfin processors?

Or is there an easier approach than can be used to implement "Modbus TCP" on Blackfin?
