Simulink coder can not initialized internal array

i have a model using legacy code to make an s-function to add an c fuinction into model, and i need set an array into it make it can calculate and change it

Here is my model below, i set an simulink object specify the variable can be trace

I found this array can not generate for an initialize value which shoud be "uint8_T rtb_sfcnSIL_HelpPutCSigWrap[8]={0}" for a correct action.

which way could let me add for internal initialize for array?

Your legacy code created s-function is not correct. The input argument u1 is a scalar U16. When setting up the legacy code tool you need to set up the u1 parameter to be a vector similar to what you did for the y1 argument.
