I am working bare-metal on an STM32L433RCT6 (no HAL). I am seeing a precise data bus fault whenever I access a GPIO register.Fault details from the debugger:Fault type: Precise data bus faultBFAR: 0x48000000From RM0394, 0x48000000 is the GPIOA base a...
Hello All,We are developing 2 MCU (STM32U5 and STM32N6) based solution which has a Wi-Fi module. There is a need that should allow either STM32U5 or STM32N6 to communicate with ST67W611M1A6BTR Wi-Fi module at any given time. The FW is under our contr...
I'm developing a power bus manager where I monitor current and voltage drop across a shunt resistor. I chose the STM32G484 as the MCU because it has enough OpAmps and ADCs for my project.However, I have a question that might only be related to elect...
I would like to know how I can program 2 MCUs (stm32wb55cgu6) simultaneously.Currently, I am programming the FUS and BLE binaries (firmware developed by the company).We need to double production, but I can't program via DFU because an error always oc...
I have an STM32L011F4P6 with an RTC. It is running at 3.3V and 16 MHz off the internal HSI RC clock. The RTC is driven by a +/-20ppm 32.768 KHz crystal. It is running at room temperature (23-25C). After calibration, I am losing several seconds pe...
Hi I have a question that blocked me for several days, Hopefully someone can help, thanks a lot.1:MCU:STM32G0B0CET6,Develop tool:STM32CubeIDE2:I wanna have a test for OTA ,so i create a bootloader project and app project3:Flash segmentation:1)Bootloa...
In my project I've set the SPI clock to 125MHz; with a SPI prescaler value=4 all works good, when I set it to 2 the SPI stops working and ther is no clock signal.Any helps ? Thank youCarloV
I call HAL_UART_Init() with LPUART1 at 20Mbaud but when I activate assertion it fail at IS_UART_BAUDRATE().The IS_UART_BAUDRATE() is not correct for LPUART that can have a baudrate up to 53.3 Mbaud.Also for UART, the comparaison in IS_UART_BAUDRATE()...
I’m working on an STM32H7R7 project using SDMMC1 + FreeRTOS (CMSIS-RTOS v2) + FatFs, all generated with STM32CubeMX.I’m facing an issue where f_mount(opt=0) works, but the system blocks inside f_open() and never returns, so the return value cannot be...
Greetings!I have the following system:STM32U073CCVBAT pin is connected to a super-cap, and it's voltage was measured to be above the required minimum.During system reset (NRST) it behaves according to my expectations, the RCC_BDCR remains unchanged, ...
