Facing error while building a model for Dspace

Hello,

I have created a simulink model for Dspace DS1104.

when trying to build the model getting the following error, can you please tell me what the issue here:

The call to rti1104_make_rtw_hook, during the before_tlc hook generated the following error:
RTITH_CODEGEN: Failed to open file .\pmsm_1_rti1104\pmsm_1_th.c. File access error, file is possibly read-only.

The build process will terminate as a result.

RTITH_CODEGEN: Failed to open file .\pmsm_1_rti1104\pmsm_1_th.c. File access error, file is possibly read-only.
Component: Simulink | Category: Block error

and if i try to build the model using "rti_build('PMSM_1')" command it show below messege:

Starting build procedure with RTI 7.4 (RTI1104, 02-May-2015)

Hi Bhupesh,

I understand that you are facing an error while building the model for Dspace DS1104.

The provided error message suggests that there is a file access error while trying to open the file “PMSM_1_th.c” in the directory “\PMSM_1_rti1104\”. It indicates that the file may be read-only, causing the build process to terminate.

To resolve this issue, kindly refer to the following steps:

1. Check file permissions:Ensure that you have the necessary permissions to access and modify the files in the specified directory. Make sure the file “PMSM_1_th.c” is not set to read-only.
2. Close any open files:If you have the file “PMSM_1_th.c” or any related files open in another application or editor, close them and retry the build process. Sometimes, file access errors can occur if a file is already opened in another program.
3. Clean the build artifacts:Manually delete the contents of the “PMSM_1_rti1104” directory. This will remove any previously generated build artifacts. Then, try building the model again.
4. Restart MATLAB and Simulink:If the above steps do not resolve the issue, try restarting MATLAB and Simulink. Sometimes, restarting the software can help resolve temporary file access issues.

For more information regarding the errors while building the models in Simulink, kindly refer to the following documentation:

I hope this answer helps you.
