STM32U585 ADC
Hi,I have a custom board with STM575VGT6 then we decided to make it smaller and move to STM32U585OI MCU.On the second board with new MCU, almost all peripherals works fine (DAC, UART, I2C) with almost no code changes, except new MCU defines, drivers ...
Program STM32H7xx over UART3 timeout
So new problem while trying to bypass non functioning SWD...Using a working NUCLEO_H723 I can use the STM32CubeProgrammer to access it via STLINK (internal and external) as well as via USB DFU after reset with BOOT0 high.From my reading of AN2606, on...
Disabling M4 core through CubeProgrammer on Nucleo STM32H755ZIQ: It takes too long
Hello all, I disabled the M4 core based on the tutorial by ST Employee mEALLEm, I pressed Apply, saw the option byte successfully programmed notification, but I have been waiting for MCU disconnect notification for 20 minutes now. The LD4 keeps blink...
SWD connection failed multiple times on STM32H725
We have a batch of custom boards using the STM32H725IGK3 and have experienced several failures getting started with them as the SWD interface appears to be fried. Initially we thought just bad luck with the first couple (inexperienced engineers or ?)...
STM32H7 DMA issue
HelloMy current requirement is to generate an FSK waveform with two frequencies around 3-5 MHz, a rate of about 700K, and output a square wave using PWM. The method involves switching frequencies by updating ARR and CCR using two timers—one for PWM o...
Resolved! STM32 GPIOs Do Not Have Partial-Power-Down / Ioff / Back-Drive Protection
For community awareness:Unless otherwise stated, STM32 GPIOs do not have partial-power-down / Ioff / back-drive protection.Example: If VDD=0V (or VDD unpowered) and a GPIO is driven with 3.3V, then excessive current may flow into the GPIO.This includ...
Resolved! STM32H7S7L8H6H XSPI instability
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
SDMMC & SAI configuration on PDM microphone - how to deal with background noise? STM32H747-DISCO
Hi everyone,I’m working on an audio recording project using the STM32H747-DISCO board with its built-in PDM microphone. The recording works — I can clearly hear my voice — but there’s a constant background white noise in the recording. I’m trying to ...
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...
