Resolved! On STM32H7 if VBAT is not connected, but VDD is always present. Does NRST maintain backup registers?
I have an STM32H7 on a custom board. We do not have VBAT connected to anything. We do have a battery always connected to VDD. When I reset the MCU using the NRST pin it seems like the backup domain (registers and RAM) are not maintained. Is this expe...
STM32l412 Nucleo-32 Dev Board has shorted pins?
The following pins appear to be shorted on the STM32L412 Nucleo-32 Dev Board :A4 (PA5) shorted to D4 (PB7)andA5 (PA6) shorted to D5 (PB6)Is it possible someone can verify, I have checked four Nucleo-32 boards and all show the shorted pins. The Nucle...
3D Step-File for STM32429I-EVAL
Hi,we are planing to build up a functional prototype with the Eval Board STM32429I-EVAL.I got the design files which were available on the product page, because I like to have a 3D-Step File of the whole Eval-Board.Unfortunatelly I can not access the...

I Connected Custom Board Via ST Link Utility based on STM32f439NI Micro controller with Revision of VQ4 and Flash Size is 2MB.When i Connected With ST Link Utility, Software Display unknown Revision id and Unknown Flash Size.what main reason behind i...
Resolved! Can I use STM32F429 Discovery Board 3V/5V pin as power supply?
I have a stm32f429 discovery board, can I use its 3V/5V pin as power supply?Image below is from mb1705c, I'm not sure the meaning of "EXT_5V, Input only".I would appreciate it if you could answer my question.
STM32G031 programming with ST-Link and CubeIDE failed
Hello, i am trying to program a STM32G031. unfortunately it does not work with cubeIDE i want to use for. please see the following message from the console:STMicroelectronics ST-LINK GDB server. Version 7.0.0 Copyright (c) 2022, STMicroelectronics. A...
Hi, we've a new custom-made electronics with two micros STM32H755. The first try connecting a ST-Link V3 via SWD was successful. Before flashing the two target files for CM7 and CM4 my colleague carry out a 'Full chip erase'.
After that, both files could be flashed. After a RESET we got the following error message:Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication 18:06:27 : UR connection mode i...
Program custom target with nucleo st link
HiI have a Nucleo F103RB where I would like to use the st link to program my custom board with a ST321F03. I removed the jumpers on CN2 and connected SWDIO, SWCLK and GND.When I try to connect via SWD with CubeIDE I get "Error in initializing ST-LINK...
[STM32F103] External circuit from remote BOOT activation
Hello,I'd like to design PCB's for ordered MCU's (I do not have them yet, so I cannot perform any tests...)I wish to perform full flashing without touching the PCB, using Bluetooth (HC-05).I'm looking for a way to acitvate bootloader mode remotely. I...
