Data types mismatch in Simulink

Dear all,
in the attached file you can find a project, obtained by following the instructions in SoC Blockset User's Guide, page 2-34 (Create an SoC Project Application).
When I run the project I get the following Errors:
Could you please help me to solve the issue?

Hi @Sergei,
I understand that when running the model you are encountering data type mismatch issues.
Regarding the second error - "Data type mismatch". It is clearly stated that Input port 2 expects a signal of data type 'double', but the currently it is 'uint8'. I recommend you to refer the following MATLAB Answer post : https://www.mathworks.com/matlabcentral/answers/92959-why-do-i-receive-a-data-type-mismatch-error-when-using-a-model-reference-in-simulink
Also, Could you please attach the model file/project for better recommendation.

Sorry for the confusion - attached the project now.
I chiked the Data types to the best of my knowledge - everything seems right, but the multiplication block inside the FPGA algorithm wrapper seems to expect double instead of int8, that is provided from the Register Channel
