STM32G0 Engineering bytes programming
What is the sequence and APIs to erase and program the Engineering bytes?There are APIs to handle Main flash, and APIs to handle OTP, but it is not clear how the Engineering bytes should be handled.Thanks

STM32L562 UART Data Rx packet loss
Hi,I am using USART4 in STM32L562E-DK eval board. with given configuration. In which I am able to transmit the data correctly on TX based on which UART slave device is sending back the 4 bytes ACK and 16 bytes RESPONSE.Using following codevoid HAL_UA...
STM32U031 SPI receive data of arbitrary length
Greetings!I am using the STM32U031 with STM32CubeMX HAL as an SPI Slave and would like to receive data that has variable length (max 50 bytes). I am using software NSS and my current approach is to start a DMA Rx/Tx transfer (using HAL_SPI_TransmitRe...
STM32H7B3 continously resetting when executing code from external flash
We have a working production firmware for the STM32H7B3 that uses a Winbond W25Q01JVZEIM external flash using QSPI in memory-mapped mode to store data and assets for a TouchGFX and other applications.Now, due to internal flash limitations, we are att...
Resolved! STM32u5 ADC not reading 4 channels properly using polling mode/ADC scan mode)
Hello, I am working on simple program to read ADC using the STM32u585QII microcontroller. I am using polling method in Scan mode on 4 channels. All set as 14 bit but understood the readin will be in 12 bit. The problem is the values I am getting are ...
Resolved! What is the cpu state when exiting standby mode
When the MCU is placed in Standby Mode, where does the CPU begin to execute when exiting the mode? (for example, on an RTC event) Is it a reset or a return from interrupt? RM0394 isn't clear on this.
Resolved! FDCAN with BRS activated: Problem transmitting 64 Bytes on FDCAN
Hi all, I am trying to use FDCAN with Baud rate switch (500 kB / 2 MBit) activated and I want to send 64 Byte. Processor is STM32H7A3. Project was set up with CubeMX V. 6.11.1 and HAL FW_H7 V1.11.2. Clock for FDCAN is 80 MHz. The problem is that th...

STM32L072 – LPTIM1 external pulse counting with LSE in STOP mode not workingDescription:Hello,I am trying to configure LPTIM1 on an STM32L072 to count external pulses from a button connected to PB5 (LPTIM1_IN1). The goal is to keep counting pulses wh...
STM32N6 VENC Hardware Handshake with MJPEG encoding
The VENC peripheral on the N6 boasts a hardware handshake path with the DCMIPP peripheral, potentially allowing full compression of each frame to occur with very little active RAM. From what I can find, the DCMIPP capture starts, then the VENC is tol...
