OpenOCD error with ST-Link V2

[tekati]

I am getting an error setting up OpenOCD with my STM32F4Discovery board. I am pretty sure it has to do with the WinUSB drivers. I can install the STLink utility from STM and it works until I install the WinUSB drivers when trying to setup the settings for VisualGDB in Visual Studio. Once that installs the WinUSB drivers and it fails I can no longer use the STLink Utility until I uninstall the WinUSB drivers.

When I hit the detect button it does find the STLink-V2. But once it prompts to install the WinUSB drivers this is the error I get.

I have the same, since I upgraded Debug Package. So I started to use SEGGER J-Link. It’s very annoying …
I tryed to find previous version of OpenOcd, but I failed… =(

Hi,

Can you try starting the Driver tool (select ‘manual mode’ in OpenOCD settings) and trying to manually install the WinUSB-LibUSB driver for the ST-Link device?

but it works! Test is failed, but at least I can work with it.
Just every time it download program to FALSH, no metter what, even if did’n change anything 👿

Hi,

LIBUSB_ERROR_ACCESS looks like a permission problem. Does running Visual Studio as Administrator help?

with Admin mode

Hi,

Do you see the same behavior if you select the “LibUSB-WinUSB” driver via the Driver Tool?

[darksilence]

But it is lib-win driver

Hi,

The “init mode failed” message is shown by OpenOCD when it has opened a handle to the ST-Link device, but the device refused the initialization command. This can be an indication of an old firmware used on your ST-Link. Can you try updating the firmware using the ST firmware update tool? If this does not help, please share the current state of the problem:
Does the settings testing always fail or just sometimes?
Does debugging work (always/sometimes/never)?
What exact problems are you experiencing with FLASH loading?
