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 ...

Many times, using serial communication at 115299 baud, when I jump from the bootloader to the application, although I receive a positive response, the application does not start (never reaches the main of the app).I am using a STM32H755IIT and I have...
Hi All,I have a project data logger using STM32F4 and send data to the local server using an Ethernet interface. I use Lite W5500 Ethernet Module. Could anyone share the example code, hardware configuration n wiring? Thanks a lot
When doing triggered (EXTI2 line) DMA transfer with SPI in circular mode I often don't get the expected result. If I do the DMA transfer (non-circular) from the EXTI2 interrupt everything is fine.Code transmit 10 bytes, receives 10 bytes each transfe...
