I am using s32k144 i am getting this error

Multiple errors reported.

1) Unable to create variable object

2) Failed to execute MI command:
-var-create - * "(float)((i_alpha * acos((double)theta_elec)) + (i_beta * asin((double)theta_elec)))"
Error message from debugger back end:
'acos' has unknown return type; cast the call to its declared return type

3) Failed to execute MI command:
-data-evaluate-expression "(float)((i_alpha * acos((double)theta_elec)) + (i_beta * asin((double)theta_elec)))"
Error message from debugger back end:
'acos' has unknown return type; cast the call to its declared return type

4) Failed to execute MI command:
-var-create - * "(float)((i_alpha * acos((double)theta_elec)) + (i_beta * asin((double)theta_elec)))"
Error message from debugger back end:

Hi @sona1

Did you already add the math library in the Project Settings? Check the following thread. It has information related to the topic.

Hi @sona1

Try just casting the call to the proper return type.

The debugger requires some information before calling the functions if you call a function that returns a value, but generates code as though the function returned a scalar value, calling the function will corrupt the stack of the thread on which the function was called, ruining your debug session.
