STM32 MCUs Boards and hardware tools

This is a specific question Programming a new IC STM32030 using an ST-Link and STM32CubeProgrammer. I have spent considerable time trying to understand why I cannot connect to my stm32. I have attempted to connect and program through STM32CubeIDE also.

The St_link registers itself and the serial is updated etc. however when I attempt to connect to the newly soldered chip, I get the message that "No STM32 target found".Am I attempting to program this chip incorrectly by using the SWDIO, GND, SWCLK a...

How do I resolve the problem of "Failure loading STLinkUSBDrive.dll" that keep coming up when I click Program Verify

STM32L152RE Schematic Verification

I am trying to create custom PCB for my academic project. This is the first time i am using an STM32 processor. I will be grateful if someone can verify the schematic for STM32L152RE which i created.I will be using SWD to flash code to the STM32. The...

What is the correct recommended pad size for the STM32 in the TFBGA240+25? The Table 135 of the datasheet seems incorrect.

With a ball size of 0.4mm I would expect a pad size of 0.36mm , but 0.225 mm is in the table.

Does anyone know of documentation/reference manual that describes exactly how the ST-Link USB driver works on Microsoft Windows so that a custom Windows application can be written to communicate with the ST-Link USB driver to download code to a STM32H753?

OHMs between VSS and VDD falls down to minimum value.and CPU RUN led turned off within few minuits.

we are developing HMI(ethernet,sdcard,4.3 inch tft touch display) using STM32F746 microcontroller with 6 layer pcb,we already did one pcb and its working perfectly.and we started 2nd one almost at the end of the process found random auto reset,cpu ru...

debug breaks when the relays operate. The system continues to run

I design a PCB with a stm32f407.Relays come into play shortly after debug starts. sometimes the debug fails and closes when the relay activates. What should I do to prevent the debug from closing?relays are driven with 24 volts and lm2803.The st link...
