Simulink Build Error : Type mismatch in initial value

I was getting build error as below, when I did not match the Data types.

Invalid output port data type. Data type of 'Output Port 4' of 'Integrated_HAL_BSW_ASW_ver1_05/BSW_ASW_Interface_INPUT/ASW to BSW Interface/Bus Selector1' is invalid.

The below picture shows the problematic area of my model. The output of the Stateflow is linked to the Bus selector.

Then I managed to match the data types, but now I am receiving the below error.

Type mismatch in initial value. Data 'PumpBatWp1Out_RPM' is set to be of type 'uint8' and its initial value '0' evaluated to type 'double'.

If I also have to match the initial value data type, how can I change the initial value data type? Please help me to solve this.

Thank you

Could you try to specify uint8(0) instead of just "0" as the initial value for 'PumpBatWp1Out_RPM' in the Stateflow Symbols Pane > Property Inspector? Otherwise, it is assumed that the 0 is double.
