Hello,Any access to the calibration memory addresses of the analogue temperature sensor or the internal reference causes a hard fault if ICACHE is enabled.Here is an example:ui16Temp = __HAL_ADC_CALC_VREFANALOG_VOLTAGE(0x0BF0, ADC_RESOLUTION_12B); MX...

Hello,I try to use the FPU exception interrupt handler in STM32H743ZIT but the FPU interrupt is not coming. I initialized the interrupt in this way:HAL_NVIC_SetPriority(FPU_IRQn, 0, 0); HAL_NVIC_EnableIRQ(FPU_IRQn);Than provoke a division by zero FPU...

The function using ADC_CALIBRATION_TIMEOUT. This timeout is defines as:/* Fixed timeout value for ADC calibration. */ /* Values defined to be higher than worst cases: low clock frequency, */ /* maximum presca...

Hello I have a custom board with a STM32H753ZIT and I’m wondering about the amplitude of the HSE crystal. It is only 300mV (see the attached Image). It seems to wok but is this normal?The crystal requires a load capacity of 20pF per datasheet, the ca...

When for ADC2 Channel 18 is selected as Injected Channel and initialized via “HAL_ADCEx_InjectedConfigChannel�? it will return HAL_ERROR.When no other ADC it will fail in line 2288 2286*. When another ADC is enabled it will fail in line 2277 2275*.HA...

Same issu in the H7 1.5.0 Driver.Fixed it by adding uwTickPrio = TickPriority; in HAL_InitTick of stm32h7xx_hal_timebase_tim.c

I was facing the same issue. I was able to solve this by adding: SCB_CleanDCache_by_Addr (uint32_t *addr, int32_t dsize)after writing to the backup RAM.The issue was that the data was still in the cache and has not been transferred into the SRAM when...

No one else facing this issue?I have attached a test project for the STM32H743ZI-Nucleo Board. When it running the green LED1 is blinking. If the user button is pressed a division by zero is provoked. In case the division by zero bit in the FPSCR reg...

Thank you Jan for looking into.UI read 300mV on pin 23 RCC_OSC_IN , 220mV on pin 24 RCC_OSC_OUTIt is a 10Meg probe with 15pF. I also tried to take capacity into account but without significant difference. We are using the same type of crystal for the...

@Community member Thanks for informing ST. Whoever is taking care on this topic should also check if a similar issue exists in stm32h7xx_hal_adc.c staring in line 2548 as the code looks Identical. I haven’t looked deeper into but at least the commen...

Re: STMHAL STM32L152RETx - If you use TIM2 as the timebase source, it will assert in HAL_NVIC_SetPriority() due to uwTickPrio not being set in the TIM2 version of HAL_InitTick()

Re: I can not use backup RAM for STM32H743BI. Is there any application note or source code for backup RAM.
