An error occurred in Auto compile and download process. Please refer the log data above.

We need to investigate a little bit on this issue. Could you please attach project01.slx model file and the project01.h file in 'D:/waijung2_20_10a/mySourceCode/project01_esp32_build_system/main/include' file path. We will find a solution for this issue and let you know as soon as possible.

You can attach a file as in the following figure

Please see both files as attached

How about to solve my problem?

Sorry for the delayed response.

The issue is, Matlab generates the c++ code instead of the c code as in the following log data in the Simulink Diagnostics Viewer.

As in the above reference image all the generated files are .cpp files. It happens because the configurations of the Embedded Coder has been set for the c++ code generation, not for c code generation.

To change it to c code generation please click on 'Embedded C++ Code' and select 'Embedded C Code' as in the following figure

Once the configurations are changed and build the Simulink model again the C code should be generated as follows

Please follow the above steps to solve your problem. And let us know if the problem still persists.

After we change to c code generation and built the code, but still found the error as attached,

Is it the same model that you attached before?
Can you try deleting the project01_esp32 folder and project01_esp32_build_system folder, building the model again and let us know whether the problem still there.

Now, we can download by create new project but LED2 on esp32 not blink. Refer as schematic as attached.

Glad to hear that the model can be compiled and downloaded without any error.

One of the reasons for not blinking the LED is current pin configuration in digital output block is set to Open drain. According to the schematic, GPIO2 should be configured as Push-pull. It can be configured as in the following figure.

And let us know whether the problem is still persists.

Ohh, It's big mistake for me and now program it work well. Thanks for all that you replied to me.
