STM32U5 option byte writting through bootloader
Hello, I am trying to write to the option byte area of an stm32u5g9vjt6q using the built in bootloader over the canFD protocol. I have verified I am able to erase and write my programs to flash over canFD using the built in boot loader so I know tha...
STM32F405 TIM DMA work only once
Hi ST team,I'm implementing DShot protocol with Timer + DMA. I use 4 PWM channels to generate control signals for ESC. Timer and DMA's parameters are same for all PWM channel. But PA3 (TIM2_CH4) does not work the same as other PWM channels. It only t...
Unstable logical state on every I/O pin
Hi Everybody! I confronts a very interesting problem at my project. Details above:Hardware: NUCLEOG071RBAttached the IOC configuration. Control the SPI CS pin by software. I got small 4-8us signal spikes all GPIO, SPI, I2S pins. SPI and I2S powered ...
How to ensure interrupt handling before going to sleep/stop mode
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
STM32G473 QSPI indirect read times out at higher frequencies
I have a custom board with an STM32G473 running at 170MHz. I have the QSPI peripheral running correctly in indirect mode when the pre-scaler has a value of 5 (so ~23MHz) but when I decrease the pre-scaler any further all HAL_QSPI_Receive calls end up...
Resolved! Voltage Level Shifting for STM32: Resistor Divider vs. Level Shifter IC for Analog Signals
I have a question regarding voltage level I/O compatibility for STM32 MCUs. The sensors providing analog output within a 0–5V range, while those with digital output at either 0V or 12V. Although some GPIO pins on the MCU are 5V tolerant, they are sca...
STM32L476 SRAM2 Parity disable cannot be turned off.
I conducted some test in case the option bytes in the STM32L474 (Nucleo 64 board) are set incorrectly for my application. Note HAL is not used (it's a strict bare metal application since this is a home experiment to reduce power consumption to the ba...

STL v4.0.0. : Flash test not passed + bin file size is 393MB
We have tested the STL package in 2 scenarios for Flash test on STM32L452: CASE 1: Linker settings:FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 512K Pre-Post build settings:0x08000000 0x08080000 0x400 STL user template settings:/* FLASH configur...
