Spartan 3ADSP security DS2432 chip

Has anyone worked with this chip. This is a low cost solution to protect the bitstream of the FPGA. There is an aplication note from Xilinx Xapp780 , which explains what to do, you must first load a key in DS2432 chip, and then once you boot the FPGA with the correct key, the system doesn't boot. I can achive the first step with no problems, the problem arises when I try to authenticate the system from the FPGA.

any comments would be helpful

Thank´s in advance

Can you give some more detail on the failure you are seeing at step 2?
