Resolved! Need Guidance on QSPI External Loader Issue with Custom Board Using STM32H750

We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...

audio device class with stm32h750 usb_otg_hs meet xact error when set interface to 1

i use stm32h750 as a decoder to translate use audio data into i2s 16bits 48khz data.however, when i use usb_otg_fs, everything works properly,but when i use the same configration and only switch to usb_otg_hs,some problem has occured. i use usb3300-e...

Resolved! NOR Flash Write-While-Erase-Suspended?

Hello,maybe this is bit off-topic, but does anybody know if it is possible to suspend an ERASE operation and write to another (previously erased) sector?I want to save a page in flash in case of a power outage and want to interrupt a probably ongoing...

DAC operation in STOP2 mode using on-chip peripheral option on STM32L496

Hello, According to the STM32L496 reference manual, the DAC should be disabled before entering STOP2 mode, which implies that it doesn’t operate in STOP2.However, in STM32CubeMX there is a configuration option for DAC output — external pin, on-chip p...

Wake up from Standby by RTC AlarmA in STM32U575

Hi!I’m currently building an application where I need to periodically wake up my NUCLEO-U575ZI-Q from Standby mode using RTC alarms. I’m aware of the Wake-Up Timers, but I’ve been specifically asked to use alarms. This will be integrated into a FreeR...

Resolved! Trying to run a blinking LED on STM32H755ZI-Q

Hi, am new to STM32 and i am trying to configurate my Nucleo but i don't understand my problem i am trying to setup a basic blink code with the basic structure (serial port communication with putty , debugger stlinkv3 and communication between cores ...

S2LP Sniff mode: Packet drop issue [ S2868A2 + NUCLEO-U083RC (868 MHz) ]

Hi all,I’m currently working on a wireless mesh network project using the S2868A2 expansion board with the NUCLEO-U083RC, operating in the 868 MHz ISM band.This system is designed to be low-power, which is why I’ve selected the Sniff Mode (LDCR) feat...

Resolved! Using HRTIM to Output PWM input from the other Timers

Hello everyone,I am doing a project of sampling a PWM signal and reproduce it dynamically using the HRTIM. The following code:uint16_t oldPer = 0, oldDur = 0, update = 0;uint16_t newPeriod = 0;uint16_t newDuration = 0; void HAL_TIM_IC_CaptureCallback...

STM32H75x max. Clock for SPI Read Timing

Hello,I'm trying to figure out the max. reliable clock frequency for NOR flash connected via SPI or QSPI interface.I've read here or here that there are custom board and evaluation board designs which are reading data at single transfer rate up to 1...
