Resolved! Nucleo 144 STM32H7 ESD protection

Hello!I have a question about ESD protection of Nucleo 144 STM32H7 development board. As I've noticed from the schematics the board uses ESDA7P60, ESDALC6V1, USBLC6-2SC6 and USBLC6-4SC6 for ethernet, buttons, SWD connectors and USB.Isn't it easier an...

Resolved! UART weirdness on STM32H747i-DISCO

When transmitting with a UART on this H747 board, a sent string will only get through two characters before HAL_UART_Transmit() hangs. No matter how I format the string (e.g., with or without snprintf() ), this same behavior occurs for UART8 and UART...

set up the bootloader in stm32f103vbt6tr

Hi,"We are planning to design a custom board using the STM32F103VBT6TR microcontroller and are looking for guidance on how to set up the bootloader section in the schematics. Specifically, we want to enable the ability to reprogram the microcontrolle...

Resolved! Having trouble receiving more data than my USART DMA buffer is set to

Hi All,I am trying to get my Nucleo-U575ZI-Q to receive low level USART data using DMA. I have set it up to be a circular buffer in the IOC file but everytime I receive 1024 bytes for example after that it won't receive anything.When I call LL_DMA_Ge...

Resolved! Is it possible to restore ST-Link Firmware (Factory reset)?

I got my STM32H745I-DISCO (STM32H745XIH6U) kit and wanted to update st-link (STLINK-V3E) firmware. Unfortunately I used unreliable USB cable and it got probably disconnected during the process. Now the STLinkUpgrade shows the line "Unknown firmware t...

Resolved! Nucleo -L476RG and Accelerometer

Hello, have been working with my L476RG and was curious if any of the ST accelerometers would be compatible with this board? I didn't see any in the X series of nucleo expansion boards.ThanksDG

STM32H735 debug/flash problem

Hi, I have a board with STM32H735I.I can only detect the IC when boot0 is tied to 3V3 effectively putting the MCU into DFU bootloader mode. In this mode, I can flash it OK with stlink or even USB-DFU. However, once I tie boot0 to gnd the device won't...

Lwip, netif_is_link_up

When running on the STM32 F746 eval board, the code does not go into the "netif_is_link_up(&gnetif)" function in the lwip.c file. For this reason I cannot ping. How can I solve this problem?

Read Protection Problem

Hello. I have an STM32F407 Discovery Board. I have been using the same board for years. Last time i used it i was experimenting a speed control of a DC Motor which i had done it many times. After i started debug mode my board strangely shut down and ...
