Using an STM32H5 I recently came across a problem: triggering a hard fault when accessing data in FLASH (read FLASHSIZE_BASE).It turns out in this thread that the ICACHE being validated, it is necessary to configure the MPU to make “uncacheable” the ...
Hi all, I've recently begun playing around with Zephyr and made blinky for a custom board with a STM32H755.To test it, I made a complete chip erase and then I flashed the application to the M7 (i.e., its flash area). I can then attach to a debugger i...
Hi, we are using the MCU STM32H725IGKx (UFBGA176) ADC3 configured as follows. /** Common config */ hadc3.Instance = ADC3; hadc3.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV1; hadc3.Init.Resolution = ADC_RESOLUTION_12B; hadc3.Init.DataAlign = ADC3_...

Hi,We have a STM32L031F6 which is used as an RTC. A weird phenomenon is occurring: when the controller goes to sleep, it only uses 2µA, but after 2 minutes and 40 seconds, it starts consuming 50 to 100µA, depending on the hardware board used. There i...
Hi I m aware FDCAN can be configured to work in class CAN 2.0 mode, could anyone advise how to configure this in the ioc? i.e. frame formate, mode , Time seg .... etc Thx
I have been trying to transmit and receive from putty through the USB virtual com (CN1) of the core board, I tried with different baud rates and the result is always the same, garbage arrives at the putty, and I am not receiving anything either, it i...
I am having trouble configuring my TIM6 to toggle a GPIO pin every 1 usec. I am using the HSI at 16MHz as the source for AHB bus clocks, which TIM6 is on. The following is my System Clock configuration:void SystemClock_Config(void){LL_FLASH_SetLatenc...
Hello guys! I have a problem. I need to use HAL_RTCEx_SetSynchroShift function from HAL to modify the subseconds of the RTC module. The problem is that this function cannot work because the REFCKON bit from Control Register is set(1). First, I do not...
Folks, I have a device that installs into another product and provides SRAM for code execution for the other device. The device my board plugs into has a fixed 500ms RESET generator that hold off the host device CPU for that much time. During this ...
