I'm using the SDK 2.3.0 for the LPC54018 IoT_module. I'm trying to make the AWS shadow wifi example work, my problem is that no COM Port is emulate.
I understood that as the SDK_DEBUG is defined to 1, I can't use semihosting. I checked that the UART box is checked when downloading the example. Do you have the same problem, and if yes did you find how to solve it ?
Have a nice day,
Kévin

Hello Kévin!
It's normal that you don't see any COM port emulated. Once you make all the configurations in you project (SSID of you wifi, your endpoint, etc.) Go to the debugg session and the program will stop at the first line waiting for you to click run. Go ahead and click run and once the debugg session is running go to Tera Term (or the terminal you are using) and the COM port will be there, so you just have to select that and you are good to go. You don't have to change any configuration of the semi hosting or SDK_DEBUG.
Please let me know if you have any more questions!
Have a great day,
Victor.

Hi Victor,
Thank you for your answer. We do wait for the program to stop at the first line, run it and then check for the COM port but we don’t get one.
I’ve tried the same program with the Segger IDE and it worked perfectly.
Also, sometimes the program don’t stop at the first line and run itself after cliking the debug button.
Have a great day,
Kevin

Thank you for your answer, it help make the project work. We still have few problems when we are in debug mode (the wifi connexion is not working). Have a nice day.
Hello Kévin!
The communication for this DEMO is USB, so if you stop in the debug mode this will break the communication and the program won't work correctly. So I recommend you to don't add break points and don't debug step by step, just run the whole application. If you get some error you will see it at the console.
Hope it helps!
