During testing, Suddenly HOST PC stop detecting the board saying unknown device. NO VID/PID was recorded also. So, we need to upgrade the firmware again But the ST-Link USB is not working only. Is there any other way to upgrade it. Kindly suggest
I am having problems with the clock signal supplied from ST-LINK chip and need to exchange it with a clock signal from a stable oscillator. For that I need the layout to find the power lines and the diagram to identify jumpers. The schematic and layo...
Cannot connect to STM32L05x MCU with CubeProgrammer and ST-Link V3 using the CLI with both "connect under reset" and "Normal" modes. However using the same setup I can connect with ST-Link V2.Is there any reasoning for this?
I have Discovery kit with STM32F411VE MCU (LINK), The product description doeasnt talk anything about the re-enumeration capability of the on board ST-LINK debugger/programmer.Is it possible to tweak some jumpers or tweak stlinks firmware to use this...

Hello,is it possible to replace the ST-Link MCU on a STM32F4-Discovery board? It seems that the ST Link on the board is broken :( Regards
I have a custom board which always enters the DFU USB system bootloader when powering on, even though BOOT0 & BOOT1 pins are driven to ground. After I load a simple test program on it (via dfu-util), it runs the program just fine. However, when I rem...
Hi,Can someone throw some light in here, please ?I have a Nucleo-H743ZI2 (MB1364C) board. From schematics it appears to me that UART3 is connected to STLink and can be used as a regular COM port ?Is it possible to use UART3/VCP on the STLink as a re...
I am new to stm32 programmer core, I tried to the stm32 with Eclipse GUN ARM. I followed the instrections which included flashing the stm32 debugger/programmer core with J-link.Now I want to re-install ST-Link on the STM32F407VG. Kindly point me in t...
