I have been trying to connect to stm32f30f4p6 using SWD but it shows cant connect to the device.

But when i connect other MCU it is able to connect to it .

Also, stm32f030 connects to the utility in another laptop.

Tripple check your wiring. Try to connect under reset!

Check the electrical: MCU supply voltage, SWDIO and SWDCLK signals and ground, reset pin voltage level, boot pin level.

For external ST-LINK the target voltage needs to be applied to pins 1/2

>>Also, stm32f030 connects to the utility in another laptop.

Is the non-working one a DELL? Through a hub or expansion dock?

Different policies or AV software? Remote Diagnostic tools?

Different drivers? Upper or LowerFilters on driver stack?
