STM32F4 Discovery: ST-LINK bricked

Hello,

out of a working setup, suddenly I dont get any connection to my ST-LINK anymore And LD1 is blinking red (f ~ 0.5 Hz). PA13/14 are not used in my program.

Even in Device-Manager there is no ST-LINK recognized anymore. Another Discovery board works perfectly.

What can I do to reanimate my precious STM32F4?

If your code is causing a problem pulling BOOT0 High at start up will remove it from being an issue.

thanks for the reply. i tried that, but it didn't work. Maybe the ST-Link Controller is defective?

Perhaps, or may be you changed something. Like drivers, or installed something else? Moved some jumpers? Add circuitry, damaged a regulator?

You could try on another system with a fresh install, or try a different discovery on the same system.

Unfortunately, another identical F4-Discovery works with same setup, jumper-config and USB-cable...

I cannot rule out a surge peak on any pin due to ESD, or that I accidentially touched a pinhead with 5 VDC.

Is there any possibility to reflash the ST-LINK part of a discovery board?

Hi,

Windows 7 does not detect my STM32F0 discovery board. I am getting the following error:

Windows has stopped this device because it has reported problems. (Code 43)

It was working fine and all of a sudden its not getting detected.

Any resolution??
