I have an STM32L4R5ZI-P on a custom PCB. When designing the PCB I did not think far ahead enough and do my due diligence when it came to assigning and wiring pins on the STM32 in order to flash it. My design incorporates USB D connected to my PCB wh...
Hi Everyone,I am facing an issue with my MCU entering low-power mode.My code works fine when tested separately. I can successfully put the MCU into STOP 0 mode and wake it up through an EXTI line interrupt, but only when the Window Watchdog (WWDG) is...
Hello together,like many others here, I have the problem that after a short time, the debugger closes with the error message “Failed to get status,..”.The board is the nucleo-F767ZI. It has already been mentioned in the forum that it could be due to ...
We have a custom board using STM32H750IB and a single QSPI flash memory MT25TL01G. The QSPI pin for the flash memory is the same as STM32H750B-DK board, which is PF10 for CLK, PG6 for CS, PD11/PF9/PF6/PF7 for IO0-3. I saw several posts mentioned the ...
Hello Everyone,I am currently using LPUART2 for communication between an MCU (STM32U031) and an MPU (Application Processor).Configuration parameters:Baud rate: 9600Stop bits: 1Parity: NoneData bits: 8Description:Data exchange between MCU and MPU work...
Hi everyone,I am using the X-NUCLEO-GNSS1A1 (Teseo-LIV3F) with a NUCLEO-H753ZI board.The UART2 interrupt is working correctly, verified by "[GNSS_RX] UART RX Callback triggered",but the GNSS module does not send any "$GPGGA" or NMEA sentences.Only bi...
Hi,we have an STM32H735G-DK eval board with product identification DK32H735G$AT3 but can not find the differences to older DK32H735G$AT2andDK32H735G$AT1product versions in the user manual:https://www.st.com/resource/en/user_manual/um2679-discovery-ki...
I would like to test UART Bootloader on my NUCLEO-C092RC.System Bootloader mode can be selected pressing the BOOT (B3) pushbutton while resetting the STM32C092 mcu through RESET (B2) pushbutton and without the ST-Link interference removing JP2, JP4, ...
Title edited to be clear that this is on a NUCLEO-F303ZE board.Hello all.I'm trying to write a simple message via UART to Putty using stm32f303ze microcontroller. I'm using USART2, via ST-link. All the configurations have been confirmed (baud rate, C...
I am working with STM32H747I -DISCO board I am using CubeMx version 6.15, firmware: H7_V1.12.2, Freertos CMSIS2 - V10.3.1configuration 1 : Generating from touchgfx and configuring Eth other all parameters commented in code (Touchgfx parameters).Here ...
