Resolved! STM32F746 "forgets" flashed program (and more)

I migrated to a new self-created PCB with a STM32F746IE. I noticed that if I flash anything, the program works immediately after flashing, but not after power off/on. As a simple example, I created a program with two blinking LEDs. They blink after f...

STM32G474 SPI DFU mode not working

I'm using STM32H753 eval board as master and STM32G474RE Nucleo board as slave over SPI1 communication. I've created a DFU for LED blink on Nucleo board which works fine if I download it through USB(connected PA11, PA12, 5V and GND) usinf DeFuseDemo ...

ADC Low power - consumption

Hello,I have a custom PCB with stm32L562 on it. I'm able to put it low power run mode.My consumption is 0.2mA, but if I init ADC the consumption jums to 0.3mA.I've tried to deinit it before going to stop 1 mode but it does not helpHAL_ADC_Stop(&hadc1...

STM32H745 SDIO not working

Hi,I have tested STM32H745 CM7 SD 1bit mode with out RTOS from cube generated files (STM32Cube_FW_H7_V1.7.0) and it's work fine for FATFS file operations, as soon as by adding freeRTOS in cube, the generated files have HAL SD init and f_mount works b...

Resolved! I2C speed mode is defined only by timing?

When I2C "Speed mode" changes in CubeMX/IDE from Standard to Fast, it seems that only the Init.Timing value changes in generated code.This value goes into TIMINGR register of the I2C .Am I missing anything or this value defines the "speed mode" entir...

The external RTC clock of stm32f765igt6 chip,the waveform of the clock is very small,RTC clock is very inaccurate.This is whether the crystal oscillator or capacitor selection problem, or our single-chip RTC drive problem;

For the external RTC clock of stm32f765igt6 chip, we use a 32.768KHz crystal oscillator of Epson, which is equipped with 10PF capacitor. Some of them will make the MCU unable to start, and reduce the capacitance value to 2pF, MCU can start, but we ac...
