TMS320F28388S LED Blink Error

Hi, i have a simple LED blinking code for TMS320F28388S. But its not working. The code is simple , One Pulse generator connected with a GPIO-OUT Block.(GPIO38). In actual hardware, a LED is connected with that particular GPIO pin.

When i flash a led blink code from Code Composer Studio, it works.

Please note i have selected the external crystal value correctly in Hardware settings. My connection with Microcontroller via XDS110 Debugger is fine. The code gets programmed into the mcu without any issue, but the led doesnot blink or even lights up. The LED circuit is fine, cause when i program through CCS , its works.

• Previously i have experience with TMS320F280037C and matlab simulink. I have made many projects with it,But due to some processor limitations, i had to go with TMS320F28388S. I have added the model, Please check & let me know the possible causes

• Also when i generate code MATlab somehow skip the project generation, so icant debug the code with CCS Studio

It shows this message ### Unsupported CCS Version. Skipping CCS Project creation , But the code generates, and its get programmed into the mcu sucessfully.

Thank You

Did you run the "c2000setup" command and setup for the particular new processor you are using with the required version of ccs?

Hello Harsh,

Since your code works when flashed via Code Composer Studio (CCS), but not through MATLAB, it's possible that the CCS version you are using is not supported by MATLAB. The message "Unsupported CCS Version. Skipping CCS Project creation" indicates this mismatch. You should cross-check the supported CCS versions for your MATLAB release. You can check the list of supported third-party tools for Texas Instruments C2000 processors to ensure compatibility.

Verify that your Hardware setup for the C2000 Microcontroller Blockset is correct. Make sure all configurations related to the external crystal and GPIO settings are accurate.

You should be able to identify and resolve the compatibility issues that are preventing your LED blinking code from working correctly when programmed through MATLAB.
