How to operate STM32 power on off

[ark2]

We implemented a lwip tcp server with STM32 and even sent and received messages

But when I was debugging, it was good I'm trying to disconnect ST-LINK and see if it works by turning the power on and off without debugging, but the server didn't even create it I can't connect with the client connection

So I was looking for a way, and I turned it on and pressed the rst button, and the server worked and pinged or connected But I want to make the tcp server work just by turning it on and off, but it's not working

How do I get the STM32 board to work just by turning it on and off without debugging or rst buttons?

There's no quick solution here.

Debug your code, figure out where and why it's getting hung up, and fix that error.

Hello @ark2 

As said @TDK , the best way to find issue is to debug your code.

I think also this exemple and the UM1713 may help you.

Best regards.
