Which is the best way to use ST-Link SWD with Python under Windows 10?
Hello,I want to build a small Python application that reads out data from my STM32 via ST-Link and SWD. Unfortunatelly I could find only one Python project providing something like this: PySWD. This one uses PyUSB and this one does not detect may ST-...
Hello, I use CubeMX 6.1.1 and Keil 5.33.0.0 I got error "Invalid ROM Table" when trying to flash the MCU. with Debug settings set to Under Reset / HW Reset
By default the ST-Link Debugger setting Pack "Keil.STM32L0xx_DFP.2.1.0" is Enable and I got error "Invalid ROM Table" when trying to flash the MCU. But If I just Disable the checkbox Enable in the Pack tab in ST-link Debugger setting then the flashi...
USART without response when disconnect a STLink.
Hello everybody. I have tried to configure the output of a sensor for a display and it has worked, however, it only works when I am connected via STLink, when I feed the circuit by 3.3V or 5V, there is nothing on the output. Can someone help me?
Resolved! I try to connect a Nucleo-64 board via ST-Link/v2 for debugging, but it doesn't work. I removed CN2 and and pinning as specified. But nothing happens, no connection and no led on. The ST-Link/v2 is solid red, so it should be ready.
I'm using this guide: https://stm32-base.org/guides/connecting-your-debugger.html.

Resolved! X-NUCLEO-LPM01A Board wrong voltage after calibration?
Hello,I'm using the X-NUCLEO-LPM01A Board. Today I encountered a problem with the calibration. If I set the voltage to 3.3V and run a calibration I measure at VOUT only 3V. Without any calibration I measure the expected 3.3V. If I set the voltage to ...
