LAUNCHXL-F280049C: External mode for debugging

I can build and deploy any program on the board (LAUNCHXL-F280049C). It works correctly.

For debugging purpose, I wanted to connect the board with my computer with the external mode. I have this error bellow.

I have try differents things:

• In configuration parameter/hardware implementation/target hardware resources/external mode => try both COM port (UART and dataport)
• Different switchs settings tried
• S6 : 0 & S8 : 0
• S3.1 : 1 & S4 : 1 & S8 : 1

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

Hi @Arnaud,

Could you please share the Simulink model here to try to reproduce the issue?

Please note that if there is any antivirus software or firewall in the system, this might block the UDP traffic necessary for "XCP on Serial" mode. The software must be configured to allow traffic from a specific IP port number.

Hi @Sumukh

I transfere you the main files => mainRegulation .m and .slx

How to check if the traffic is allow on a specific IP port number ?

Hi @Arnaud,

I am able to reproduce the issue in MATLAB R2023b with the given model and data. When "Monitor & Tune" is clicked, the following XCP timeout error occurs:

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

Kindly refer to the following thread where the same error has been discussed and resolved for a similar C28x board (TI F28035):

https://www.mathworks.com/matlabcentral/answers/1988388-f28035-xcp-connection-error?s_tid=srchtitle

You can also refer to the following thread where XCP timeout issue for STMicroelectronics Nucleo Boards has been discussed and few comprehensive steps have been provided to diagnose and resolve the error:

Based on the discussions in the above thread, it is possible that there are out-of-memory issues with the model that needs to be resolved. It is also possible that a host-model approach may resolve this error: a host model to send and receive data with the target model deployed on the board. This involves using Serial communication blocks in the host and target models; you can refer to the examples in the following documentation to know more:

I hope this helps with resolving the error.

Thank you to give me interesting topics to follow.

I have made a step forward and now the code is correctly downloaded on the hardware.

I have this error below that I can not understand.

It is strange, I can upload a program on the hardware. I can run it correctly but it seems to work when it's for the external monitoring mode.
