STM32G031J6, STlink not detected

I am new to STM32 programming and while using cubeIde to work on led blinking project. The project is built successfully but after this I get an error that No target found. This happens eventhough I have plugged in the board. So, do I need to use a external debugger for this or connect anyother hardware to the board so as to fix this?

Hello @AZadb.1​ ,

Try Connect under reset, and check pull BOOT0 High or low.

You have an ST-LINK?

Which?

Can you see it in Device Manager?

Check cables, make sure not to use charging cables.

Avoid hubs, and docking stations.

Yes, in device manager, under Ports it is "STMicroelectronics STLink Virtual COM Port" and in USB devices it is "STLink Debug", both of these are already updated to latest drivers but still on cubeide on STLink is detected? so is something wrong with the board or do I have to use some other STLink?

no, >No STM32 found on Target < is : stlink connect, but it cannot find your cpu , or nothing connected to stlink. no target means, the stlink can find no cpu to work on.

what you connect to debug or flash ?
