STM32F7 FMC/SDRAM deinitialization problem

Hi, I'm writing a custom bootloader that reads a *.dfu file from an USB memory stick and programs the internal/external flash accordingly.So far, everything is working fine... I've tested it on an Nucleo STM32F767 and on a STM32F746G-DISCO and I ca...

I am using STm32f429 MCu . working on some application where it need to wake up the mcu from Standby mode from USB_OTG_FS . Please any one can advice where do i start from

STM32F303 WHEN WRITE IN INTERNAL FLASH GET HARDWARE FAULT

STM32F778, VDD 1.8V, USB not working

We have a design using the STM32F778. The FS USB works fine with VDD = 3.3V. When VDD = 1.8V, the USB does not work. VDDUSB is connected to 3.3V in both cases. On some boards, the FS USB will be detected by PC as a bootloader but it does not actu...

In my project I cannot enable SysTick to save power but I have the RTC available. Now the HAL_GetTIck always returns 0 and this is bad for I2C drivers that use HAL_GetTick to measure timeouts. How can implement HAL_GetTick using only RTC?

How to set up an USB-CDC-Host and read Data from a Serial device firing values nonstop.

I use a STM32F429ZI-DISCO board that was programmed using STM32CubeMX's Code generation for a USB-CDC-Host on high speed. To generate some input data I use a Teensy3.6 as an arduino Board set up as a serial communication device. The data sent by the ...
