Hello,

I'm having issue to connect to my newly bought STM32F4 discovery board with the

- STM32 ST-LINK Utility v3.4.0

- StlinkUSB Driver V4.3.3.0

When I try to connect it's always failing with any parameter in the settings box.

Can you help me?

Consider trying different USB cables, USB ports, or computer?

Hello,

Yes I did my laptop on Windows 8.1 64bits and Linux Debian 64bits desktop with 

https://github.com/texane/stlink

.

It looks with st-link that core_id is read as 0x00, if that's help anyone.

Yeah, I'm not sure what to suggest, you could double check the jumpers connecting the ST-LINK SWD/SWCLK to the F4, and the 3V supply, and the voltage on the VCAP pins (1.25V).

Hello Clive,

Thanks for trying to help me.

I've check today at my office with an oscilloscope and I've found the issue.

The signal T_JTCK is ok on the CN2 connector on both side of the resistor R12, but completely null on both side of the SB3. So on PIN 1 of the CN3 connector there is just a null signal.

The conclusion is the PA14 Pin of the STM32F4 does not receive a correct clock.

Conclusion ST-LINK does not work.

I will contact the seller for the warranty.

Kind regards
