STLink-V2 Issue

I am having trouble communicating with a STM32F042K6T6 microcontroller (on a custom soldered board) via a ST-LINK V2. Whenever I try to connect I receive the error: “Cannot connect to target!�? The STLink V2 does register and I can see it in the soft...

Using STLink V2 with openocd sometimes persists HW breakpoints. Is there a quicker way to clear them other than disconnecting the STLink V2 for an extended period of time.

Every once in a while when remote debugging I wind up with not being able to set HW breakpoints. There's no clear indication of when this will happen, and I'm typically only setting a single break point. If I disconnect the USB to the STLink V2 fo...

Unable to debug with STM32CubeIDE after upgrading stlink firmware to V2.36.S7 version

Hi there,I am using STM32CubeIDE 1.3.0 with STM32L152x MCUs. When using ST-Link GDB Server, STM32CubeIDE insists on updating Stlink firmware to the latest version (Now is V2.36.S7). After that I get the following errors:ST-LINK SN : 49FF7606837056521...

STM32 chip detection issue while flashing

Hi STM Team,We are trying to flash code to STM32H745 through SWD interface. However, after multiple flashing cycles to STM, we unable to detect device in 2 or 3 boards.The below are list of the observations of that scenario.Once we give 3.3V supply t...

For a freshly soldered STM32F4 chip on a consumer product, is the chip defaulted to allow USB DFU when usb cable is plugged in .

I can't imagine for pre-production to have to tie boot to vcc or the like as it is described on the discovery boards. Would be complicated to do this and will have to introduce additonal circuitry like a switch or rc circuit. If so can someone provid...

Resolved! Pinout diagram for STLink V3 mini to the STM32H7 Board. STLinkV3 has Virtual com port(UART) and SWD pins. with that I want to know how it will connect to the STM32 board?

I am designing my own board using STM32H7 controller. I am trying to flash the code using STLink V3 mini cable(SWD) and STLink V3 cable is having Virtual com port(UART) also for communicating to the board to the Host PC. How this connection will look...
