HAL_Delay stuck when sdram use as data memory

Hi:I have a custom STM32F746NG board with SDRAM IS42S328200D(Address 11 bits 2^11(Row Address)*2^8(Column Address)*32(bit)*4(bank)). My goal is to use sdram as data memory, I followed example in STM32Cube_FW_F7_V1.16.1\Projects\STM32746G-Discovery\Ex...

PWM Timer Slave not getting triggered by Master

Hello, I am trying to set timer 3 as a master to timer 1 without success. Timer3 is outputting the PWM correctly, but timer1 is not getting triggered by Timer3's PWM Signal. What else am I missing?My board is STM32F429 discovery Here are my settings ...

STM32L4R7 low-power, power cycling, and the backup domain

Hello,I have some questions relating to STM32L4R7ZIT and the different ways to enter/exit low-power modes or to power cycle, in both cases without losing RTC and backup registers.VBAT is always powered. There is an LSE.I need to understand which boot...

STM32L4 Does not wake up from STOP Mode with the RTC alarm

Hi all,I am using STM32L431 and the device is not waking up from STOP mode with an RTC alarm interrupt. Can somebody pinpoint where my issues are?My configurations in the code configurator:I am enabling the crystal oscillator, enabling the calendar, ...

Hello, can you please provide a MTBF or a FIT value for the VN808TR-E and STM32H743ZIT6 ? Please, let me know. Best regards,

How to transmit hex data over spi?

I want to transfer binary data (not character) without having to worry about character conversion, so directly:uint8_t data = 0xBF;HAL_SPI_Transmit(&spi1handle, (uint8_t *) data, 1, 1000);But I get something else at the receive end, specifically I ge...

EXTI Interrupt Handler throwing HardFault for one MCU, but not for other MCU

I have two custom boards with one STM32F746 each. Both MCUs run identical code (in different projects with potentially different configuration).One MCU runs as expected, but the other MCU throws a HardFault as soon as MX_NVIC_Init() enables EXTI int...
