void USART3_IRQHandler(void) is incorrect, since USARTs 3/4 share the interrupt, it doesn't compile. What replaces 'USART3' in the interrupt handler?NVIC_ClearPendingIRQ(USART3_IRQn); is incorrect since USART3 3/4 share the interrupt. What replaces '...
Hi,I just got this NUCLEO-H745ZI-Q demo board. I'm new to STM32 devices. The demo board comes pre-loaded with a project that blinks each LED (LD1, LD2 and LD3) at different rates. Only one LED blinks at the time. By pressing the user button on the de...
Hi,I want to make custom bootloader on STM32G051. I did something, but it does not work well. After jump to the application it get stucked on some address which correspond HAL_Delay function in my application - it looks like the Systick in my app can...
Hi.I'm writing a bootloader for update a firmware of my project by usb pen drive.Whe bootloader start verify that in the pen drive there io a .bin file, erase the flash and copy teh bin in the flash defined address.The flash address is 0x08010000.Thi...
My system has my main thread, a System Timer Thread, and one called Idle that I suspect isn't really a thread. Part of my code reads commands from a UART and then acts on the command. While the code is waiting for the user to enter the next charact...
I tried flashing firmware using System Bootloader earlier and got it working only one time, you can refer to my previous post. By exploring found that there is a similar kind of bootloader that work in the Main Memory.I am getting some hands-on with ...
We need a DFU-capable bootloader for a custom board based on the STM32H750.We can't use the ROM bootloader due to 2 requirements:upload of the DFU image needs to happen over RS-485, with support for DE to an external transceiverwe need to flash the D...
Hi,I am using the STM32H747I-DISCO and wanting to write to the QSPI using Filex. I tried using the example FX_Dual_Instance, but could not get this working. Since then I have built a project step by step using the CubeMx initialization tool. Both tim...
I am using a USB CDC device on an STM32H7A3 CPU. Most of the code is generated by the Cube IDE, and I have added my own callbacks. It works fine when plugged into a native Windows host or a native Linux host. However, it has an issue when running on ...
HI,I'm using an STM32F4 device and CubeIDE SW to interface with a mouse as a host with an HID. I use the USBH_HID_EventCallback function to trigger mouse readings.Can I change the mouse's polling rate so that it will be triggering faster?The current ...
