ST‑LINK Mini V3E not detecting STM32H7 (Core ID error, high current when VTARGET connected)I’m debugging an issue with a custom STM32H7 board and an ST‑LINK Mini V3E. The setup includes a main PCB and a separate power PCB. So far:Power & Basic Checks...
I’m working with an STM32G473QETx.Does the IWDG window value cause the MCU to reset if the watchdog is refreshed too often (i.e., refreshed too early)?if I set the IWDG window value to something smaller (e.g., 1600), will the MCU reset if I refresh t...
I am designing a 4 layer PCB which uses an STM32L433 and working on the layout for the LSE and HSE crystals. I referred to the application note AN2867 for guidance, but I am confused by the isolated ground plane underneath the crystals as shown in Fi...
Dear all,I'm trying to generate a waveform using DAC OUT1.I configured pin PA4 as analog (works)I configured DAC1 without DMA and it worksI configured TIM6 and it works Then I configured DAC with DMA, configured DMA, but output never changes.Where ca...
Dear Sir/Madam,We used the STM32F072C8T6 processor in a project we carried out for the railway sector, and as stated in the link below, we currently need a SIL certificate to be able to submit it to the auditing firm.Link: https://www.st.com/resource...
Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minut...

Hello ST Community,I am working on an industrial combo vending machine controller system and would like to request a design review / best-practice feedback for an architecture based on STM32H563ZIT6.System OverviewMCU: STM32H563ZIT6 @ 200 MHzOperatio...
Hello, ADC_CR_ADCALLIN is described as "rw" . The procedure given in RM0456: 33.4.8 Extended calibration mode does not explicit recommend to reset ADC_CR_ADCALLIN after the procedure. I think it is helpfull to add in RM0456.
We are facing an intermittent EWGF (Error Warning Flag) issue during CAN communication at 1 Mbps on multiple STM32 MCUs. The same hardware and software setup works reliably at 500 kbps without any CAN warnings.MCUs UsedSTM32L443VCT6STM32L443CCT6STM32...
