The base PowerPC Book-E UISA generated by GCC should work on the MPC5554. I am not sure about the difference between the 5554 e200 core and the 8540 e500 core. Kumar Gala at Freescale probably can provide more details about compatibility with GCC's e500 support and support in previous GCC releases. David
