STM32 MCUs Boards and hardware tools

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...

For uploading SW with seiral cable(USART) and STMFlashLoader

I developed with uvison5 and STM32F303/030The software was uploaded well with uvison5 and ULink2.But I failed for uploading with serial cable and STMFlashLoader.(my colleague in Germany succeeded it with the manual)But I can’t and I don’t know why.

Electrical characteristics of L4 series BOOT0 pin

The AN4555 "Getting started with STM32L4 Series..." in 5.1.3 "BOOT0 pin connection" states the following: "The BOOT0 pin of the STM32L4 Series has a lower VIL than the other GPIO, (for details see datasheet I/O static characteristics), thus as it doe...

Dear ST supporter, As i read STM32F042C4U6 datasheet. It have 16k flash. But I can write to sector 31 (every sector 1K). I also can view memory this sector from ST-link utility. Is it have 32K flash? thanks

My debugger sometimes wors and sometimes not

Hi.I con not figure out how ST-Link and debugger works. I use ST-LINK GDB Server in STM32CubeIDE.I wrote simple c program, which blinks LED all around (it toggles LED and wait 200ms, and so on)I tested it on my desktop PC, and when i start debugging ...

Can STM32 ST-Link work on Icom IC-F3162 hand-held transceivers

I`m trying to find out if my STM32 ST-Link can be connected in some way to my Icom IC-F3162 hand-held transceiver as the radio has died completely following an attempted firmware update to the radio`s whereby my pc crashed interrupting the update. Ra...
