Hello 642142357@qq.com,
You can use the LIN example model (lin_master_s32k14x.mdl) -- just open it (found in {TOOLBOX_ROOT}\S32_Examples\s32k14x\lin folder) and click on the Build button. This will generate the C files, compile them and you'll get the executable. Depending on the settings from the main configuration block, you could also download the executable file directly from Simulink automatically (right after the build is done).
Let me know if you need help with any of these steps or if something is unclear.
Kind regards,
Razvan.
