STM32G071RBT6(Reason : (4)No device found on target.)

Hello,

I have the following problem when using the Nucleo board.

I do not have a mini-usb.

So I use to ST-LINK.

However, the following warning message is displayed.

Please tell me the solution.

Thank you for reading.

※ I use to STM32CubeIED.

check that gnd, swdio, swclk lines are correctly shared between stlink and MCU. use a multimeter to check​

Check you power supply. I would suggest connecting to VIN not VDD directly.

Thank you for the answer.

I linked it like the datasheet below.

but it isn't operation.

Can't in-bound SWD connection via that header, not how it works.

[Tesla DeLorean]

That's for OUT-BOUND connectivity.

Review the schematic, understand the circuit..
