Bool is not a Simulink data type and HDL Coder is not able to generate code for it. That is what the error says.
Please check your model to find how Bool propagates from Xilinx scope (between gateway-in and gate-way out) to Simulink blocks and try to avoid it. Alternatively, you can convert it to fixed-point data type, such as (U)Fix_1_0. HTH

Seems like this might be a Xilinx System Generator limitation. It might be best if you try contacting Xilinx Support, because not a lot of people on this forum have experience with System Generator.
