The errors you are encountering suggests that there are some missing compilers or linkers.
You can follow these steps to resolve this issue:
1. Ensure that the ARM compiler is correctly installed on your system. The error suggests that the system cannot find the specified path, which might mean the compiler is not installed or not correctly configured.
2. In Simulink, check the configuration parameters for your model:
- Go to Model Configuration Parameters > Code Generation.
- Verify that the toolchain is set correctly under Toolchain.
- Ensure that the hardware implementation settings match your target hardware.
3. Review the paths and filenames in the error message for any typos or incorrect references as there is inconsistency in the "\" used in the path
4. You can also specify your custom include headers and directories in Configuration Parameters > Code Generation > Custom Code
