STM32F4VET6 No ST-LINK detected a problem.

[HF.1]

Hello,

I want to use the board with STM32F407VET6 processor. But when debugging, it gives a "No ST-LINK detected" error. Also, I downloaded the ST-LINK Utility and when I press the CONNECT button, I see the same error "No ST-LINK detected". It shows as mass storage in the device manager. When I plug the USB in for the first time, there are 2 different drives, one of these drives seems empty, and the other gives an error and does not open at all. On the other hand, when I want to update the driver for the board in device manager, it says it's already the most up-to-date version. In the STM32CubeIDE program, when I select the HELP -> ST-LINK Upgrade option, it does not see the board at all. Finally, I wanted to try the Arduino IDE and the PORTs seem to be empty.

How should I go about working on this board?

Does this "board" even have an ST-LINK, outside the NUCLEO, DISCO, and EVAL series boards that integrate them most everything else will need the ST-LINK as an external debugger pod?

Some boards can take a UF2 or Arduino style BOOT LOADER that act like an external drive you can drag-n-drop a .BIN too.

The STM32 has its own ROM based Boot Loader, that in some cases can present as a USB DFU "STM32 IN BOOT MODE" type device, which you can connect too via STM32 Cube Programmer in USB mode.

To get into that mode there should be a button or jumper related to BOOT0, which needs to be HIGH when the chip is reset.

Provide a link to your board. At the moment I'm pretty sure the software is correct, and you DON'T have an ST-LINK

Find and read the documentation for the board you're using.

i have exacty the same proble with stm32vldiscovery did you find a solution? i have no com port also and only as mass storege. thanks in advace

The ST-LINK/V1 doesn't have a COM port​, and is no longer supported by ST. It has been obsolete for many years at this point.

Thanks very match for this ! but i receive the error no st link detected please connect st link and restart debug session. what settings i need to change in stm32cubeide? i try almost every think!

There's no driver for it​ as it's no longer supported.
