Hi,We have build a custom board with STM32H745XIH6. I am using STLINKV3 debugger over SWD interface to connect to the target. When I connect to the board for the very first time, the STLINKV3 is able to connect at 24000 KHz clock using both STM32Cube...
I was working in an application where i need to transmit data from STM32h753 to PC. For this application i used USART1 which is connected to ST-Link. Everything was working fine and suddenly STM32H753 stopped transmitting the data. Even after resetti...
Hello, I'm on the STM Nucleo-F334R8 web page (https://www.st.com/en/evaluation-tools/nucleo-f334r8.html#documentation), and I can't find the document with the electrical schematics for the Nucleo board. The only document I can find is a generic Nucle...
Hello, I just got my PCB+A from factory, and have some trouble with it when attempt to connect to stm32h723zg located on my pcb with st-link v2 debugger (latest firmware update) and openOCD v0.10.0. But if I use compiled binaries from https://github....
Background:Was debugging on STM32H7xx when I noticed that a variable that was passed by address to a function did not correctly display the value it was updated to. Where it is used 2 lines down the variable evaluates correctly (the code functions as...
Hello, I realised that there is less than none articles about this topic so I'm looking for advice here. Long story short, I'm trying to communicate with my Olimexino STM32 board with Virtual Com Port. I am using CubeMX to create the source code, and...
I a wondering if it is possible to setup the host without VBUS and ID pin assigned. I would like to use USB A type (like laptops have) socket - there is no ID pin available and I do not VBUS detection as it is always ON.
I just bought STM32F407 discovery kit.I connected Type A to B cable. The leds between B1 and B2 should turn on but its not on in my case.help me in this.
