STM32G071RB unable to make it work

Hi all,I'm trying to program this new G071RB, is the 3th device that I'm not able to make it work.. In simple word with the virgin device I can see it via Jlink and also I can program it (I've used CubeMX to make simple configuration of pin and progr...

Cannot get program to stop execution at breakpoint using ST-LINK V3 -or- Segger JLINK+.

I insert a breakpoint in the source code by toggling it Ctrl+Shift+B. I view the breakpoint in the Breakpoints window. After startup, the program is halted at the first line of code. I then press F8 to start the program and execution blows through th...

StlinkV3 fails to connect to STM32G474 using WFI

Hello,I have a Nucleo-G474RE with a simple blinker program mostly in WFI, awaking every Millisecond. I can can warm connect with STlinkV2 e.g. by pyOCD, but with on-board StlinkV2 pyOCD reportsException reading AP#0 IDR: STLink error (5): No device ...

NUCLEO-H7A3ZI-Q are not working after few hours (no ST-link connection possible)

Hello all,I would like to ask for your experience with NUCLEO-H7A3ZI-Q board. It is new board which started to be produced. I ordered 3 same boards. They were used at two workbenches independent.All products have same behavior:First 2-3 hours are wor...

Is it possible to include the ST-LINK debugger/programmer same as on NUCLEO-H745ZI on a custom designed STM32H7 board? If so, can I just program the ST-LINK processor using ST-LinkUpgrade.exe on this custom designed STM32H7 board?

Hi, I have a problem with JTAG in stm32h753. How can I enable and disable JTAG interface. I'm using HAL drivers and STM32CubeIDE.

I have permanently conected ST- LINK V3 to my STM .My problem occurs when my board is working and i try connect ST-LINK to USB. When connecting ST-LINK reset my STM. This is big problem for me.

STM32L082(CMWX1ZZABZ-078) not conneting to ST Link

Hi, I have designed a custom board with some sensors and a CMWX1ZZABZ-078 chipset as MCU and Lora module. To design the board I have copied the schematic that Murata has in the datasheet of the module, I'm trying to connect the board to the computer ...

I cannot get high-frequency oscillator to work with STM32F765VGT6 MCU.

I have designed/developed more than 140 microcontroller-based boards utilizing 8, 16 and 32 bit MCU's. I recently designed a board that uses a STM32F765VGT6 MCU. During my initial power-up test, I verified that all of the voltages are in range. Ho...
