I am using F280039C with 2023a version of MATLAB. While using the 'Monitor and Tune' option, I am able to flash the code but still seeing this error:

External Mode Open Protocol Connect command failed

Caused by:

Could not connect to target application: XCP internal error: timeout expired, in response to XCP CONNECT command

I have referred to the solution here but of no help: https://in.mathworks.com/matlabcentral/answers/1628360-why-am-i-unable-to-connect-to-target-the-model-throws-an-error-external-mode-open-protocol-connec

Attached are the hardware settings. I have checked the COM port which is selected as the Application / User UART. Tried with the Data port as well, but didn't help.

Is there any specific setting to be done for SCIA to make this functional? The current baud config is 115200.

Thanks,

Aditya
