I am certain that the links specified on the card are configured correctly. LD1 on the probe does, however, flash 3 or 4 times when it is plugged into the USB port. I have searched the internet and this forum and I am completely out of ideas to try next.Īccording to the Getting Started card in the box an LED should flash, and when a button is pressed it changes. Its as if the development board is not compatible with the driver or the driver has a problem. I have tried the same on a Windows XP and Windows 7 PC and all report similar errors. In Device Manager, under the Universal Serial Bus controllers section I have an entry which shows as 'Unknown USB Device (Device Descriptor Request Failed), which is presumably the STLINK/V2 probe in the development board. The installation appears to succeed, however, when I plug in the development board via USB Windows complains with 'USB device not recognised'. Note: Khi np chng trình nu không connect c vi mch, có th chip ã b disable Serial debug. When i try to install the stm32 st-link utility 4.6. Nhn Taget- Connect và Target- program & vertify. I am using a Windows 10 64-bit laptop with USB 3 ports and have installed the STLINK utility, en_stsw-link004.zip, which includes the relevent USB drivers. Hi I have Windows 10 with all windows updates. RN0078: STM32 ST-LINK/V2 Utility release 2.I have recently purchased a number of NUCLEO-L476 boards but cannot get the USB drivers to install correctly whch are required for both ther STLINK utility and also for System Workbench for STM32. Posted on Augat 12:53 The driver files will be installed at C:Program Files (x86)STMicroelectronicsSoftwareVirtual comport driverWin8 Open a command prompt and cd into into this directory run dpintstamd64 /LM Click yes on the driver installation boxes. ST-LINK/V2 : DB1275: ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 Status LED which blinks during communication with the PC.Direct firmware update feature supported (DFU).SWD and serial wire viewer (SWV) communication supported.While your Dev Board is connected, uninstall and delete the 'STMicroelectronics STLink Virtual COM Port (COMxx)' device from device manager. But there is a solution ) Uninstall STM32 ST-LINK Utility. JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector I had the same issue, where WIndows 7 works fine, but Windows 10 doesnt.1.65 V to 3.6 V application voltage supported on the JTAG/SWD interface and 5 V tolerant inputs.JTAG/serial wire debugging (SWD) specific features.SWIM cable for connection to the application via a pin header or a 2.54 mm pitch connector.SWIM cable for connection to the application via an ERNI standard vertical connector (ref: 284697 or 214017) or horizontal connector (ref: 214012).SWIM programming speed rate: 9.7 Kbytes/s in low speed and 12.8 Kbytes/s in high speed.SWIM low-speed and high-speed modes supported.AC6- Tools offers a complete approach, ready to work and expandable for future needs. SW4STM32 for STMicroelectronics STM32L4 mcu. 1.65 V to 5.5 V application voltage supported on SWIM interface We will be using AC6 System Workbench (SW4STM32) for in this session.USB 2.0 full speed compatible interface.STM32 applications use the USB full speed interface to communicate with Atollic, IAR, Keil or TASKING integrated development environments. STM8 applications use the USB full speed interface to communicate with STMicroelectronic’s ST Visual Develop (STVD) or ST Visual Program (STVP) software. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. Stlink-V2, Operating system: Windows 7 Stlink tools version v1.3.0 Target chip STM32F103 As it is stated, the stlink is depended on the libusb driver. 'Virtual COM port' appearances in Windows 10 (I tried default Windows driver and ST driver) but I can not open port. The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. Im using CubeMX HAL (I tried several versions) and TrueStudio.
