STM32 MCUs Boards and hardware tools

ST-Link fails due to too high RDP by mistakes. How to initialze to factory defaust if possible.

I came across a fatal trouble, Connecting ST-Link always fails. This was caused unexpected RDP operation in the debug, that may have changed RDP=1. It was observed that 'some' program is always starts even after Reset. In my observation, UART ...

STM32F407VGT6 NRST pin going Low

Hello, I have a STM32F407VGT6 built into our application, During developement Iam facing some strange issue where NRST pin goes below logic level over the time(in few days), This issue happens in some of our boards. Our Circuitary only contains 0.1uF...

Error when trying to run a program on STM32F7508-DK with OpenOCD

Hi,I'm working on a STM32F7508-DK recently bought. I've imported an example project from stm32f7 packages called Menu_Launcher. I'm trying to run the project with OpenOCD but this doesn't work and I have the following errors in the console :Info : Li...

STM32L4Q5 LP Run current consumption higher than datasheet

Dear Master,I have problem dealing with STM32L4Q5CGT6, i just turn on the peripheral like SPI, I2C, UART and set the core clock to 400KHz.in the datasheet and PCC says the current consumption (IDD) will be around 300uA.but in actual i measure the idd...

I've to desing a custom board for my internship, but it's my first time doing so. Can someone review my schematic and tell me if he spot any evident error?

Crystal Oscillator Verification

Hello,This is my first time designing a PCB for an STM32F4 microcontroller (and I only get one shot at making this board), and the specific application requires USB and a CAN-Bus. I chose a 10 MHz through-hole crystal oscillator (ABL-10.000MHz-B1U-T)...

I am using stm32f407vet6 micro-controller. when I connect it into windows laptop and try debugging with cube ide it is showing NO ST-LINK DETECTED, CONNECT AND RESTART DEBBUGGING. I don't know how to fix it. In device manager I found STM bootloader only.
