we are using STM32H755IIT6 MCU we made 5 boards with the same MCU STM32H755IIT6 all the board can be programable with verification but only one board of start to run what we can check on the board to find the problem

Hello, is there a difference in behaviour between STM32L151VET6 Revision A and Revision Z ?

STM32G030C8T6 GPIO distubs each others.

HI，I use the G0 serials firstly. I have welded 8 model machines,but I found some similar problems. For exampleOn the NO1 board, I used the pin PF1 be output.The problem is that the voltage of the MCU's reset pin is not High toVDD。So the mcu keeps r...

Hi all! Can I connect 2 STM32F401 MCU-s in JTAG chain and program them with ST-Link/v2 programmer-debugger? I have installed STM32CubeProgrammer.

STM32G071G8U6N Programming Problem

I'm making my ESC products in batches, after I downloaded the program for the chip, I tested the finished product and found that a lot of chips didn't work, so I downloaded the program again for the chip, but the download failed, I checked the voltag...

STM32CubeProgrammer 2.9.0 download to flash with problems. And 2.10 too.

Hi!I download firmware to internal flash STM32H725 over STLink V2 with STM32Cube Programmer 2.9.0. Very often after downloading firmware to chip, Cube Programmer report to log window "File download complete", but firmware is not updated or chip even ...

Resolved! Seeing opposite behavior expected from an open drain output?

I am working with the NUCLEO-L552ZE-Q and have made a very simple test circuit to test an open drain output signal. I have the pin configured as an open drain output with no pull up or pull down with the signal pulled up to 3.3V through a 1K resistor...

Hello everyone. This trying to program some STM32F427 VIT6 through DFU but USB Windows does not recognize the Board (tried different cables and computers). I have also tried to program it using ST-Link Programmer, message "Revision ID: Unknown".Some help?

what is the minimum circuit i need for a STM32 to run it and debug via SWD? Is the attached schematic sufficient? For debugging I would connect my J4 to CN4 of a Nucleo board. Sorry for the trivial question, i don't have much experience with stm32

Where to get STM32H750-DK board schematic? Was it "removed from the board manual for user convenience"?

The revision history of the manual says that the schematic was removed in late 2021. Where I can download the "removed" documentation file? What was the purpose of removal?
