Hello, I’m starting a new design with the STM32H755. I also have the dev board (Nucleo-H755ZI-Q), but I do not have its schematic.So far, the closest schematic/design reference I’ve found is Figure 18 in AN4938 (“Getting started with STM32H755”). Cou...
I get no message if i send some bytes about my terminal tool. Because i have no schematic i dont know waht going wrong. Do i need an external supply( target ) or do i need pullup resistor or someone else? A target board isnt still connected.
Hi everyone,I’m feeling a bit defeated by a task that should be "Hello World" level simple. I’m trying to get a basic printf to show up in PuTTY using a NUCLEO-G474RE, but I’m getting absolutely nothing in the terminal.I do this all the time with my ...
Hello, I am currently evaluating the STM32N6570-DK and am seeking clarification regarding a discrepancy I’ve encountered. I can confirm that there is a 48MHz crystal on board for the HSE. However, the default CubeMX projects generated by the board se...
Hello STM Community,I currently have a NUCLEO-U575ZI-Q board and the X-NUCLEO-IKS4A1 motion MEMS and environmental sensor expansion board. I’m looking to add BLE functionality and was considering the X-NUCLEO-WB05KN1.Before proceeding, I’d like to as...
I have designed a STM32H723 board with LAN8742A PHY IC and its connected to a Hanrun HR911105A Magjack. I am running the Ethernet stack on mongoose network library. The stack is working perfectly on a STM32H7 Nucleo Board, the link auto-negotiates to...
Hello, I have a Nucleuo-F767ZIT6 board on which I verified a Ethernet code using FreeRTOS in Netconn API, there the code works fine without any issues. So, I moved on to designing a custom board for the same controller the first board worked without ...
Hi,I am experiencing issues with UART single-wire (half-duplex) communication on an STM32H723. The UART handler reports error code 4 (frame error). I have tried a wide range of configuration settings without success.The same setup works correctly on ...
Hi STM Community,I’m currently working with the NUCLEO-G491RE board and need some guidance regarding DFU (Device Firmware Update) mode.According to the documentation, CN2 is marked as the DFU connector. Based on that, I have soldered 4 pins on CN2. I...
I am using an STM32H755ZQ device and unable to start a debug session using STM32CubeIDE + ST-LINK (SWD).The system uses two STM32 controllers, where firmware is flashed to one controller and data is shared/communicated to the second controller.Debug ...
