Hi,I am working with a custom board using an STM32N657X0H3Q and cannot for the life of me bring about a reset via the NRST pin.I have tried applying the workarounds from errata sheet ES0620 - Rev 3, sections 2.2.19 and 2.2.23, but my device still just hangs when any reset is attempted and needs a power cycle to recover.  In our setup:MCUboot and the application are both built as secure firmwarethe application runs from AXISRAM1 after RAM-loadSince it runs from AXISRAM1 which is where the errata recommends to place the First power-on reset flag, I instead decided to set the CORE_RESET_TYPE bit in the SYSCFG_CM55RSTCR register before each reset (in addition to resetting the clock switch control bitfields to their defaults). Does this type of setup have any implications regarding using the SYSRESETREQ bit to generate a software reset?  Thank you/ Silvia

Hi,this one is similar to https://community.st.com/t5/stm32-mcus-products/ioselect-option-in-stm32h563-is-not-working/m-p/681099but not the same.

Hi,I’m working on an STM based UI with multiple dynamic graph widgets on a single screen and running into a hard fault when scaling things up. Right now I have 5 graph widgets, each needing to plot around 700 data points dynamically. However, when I configure all 5 graphs with 700 points each, the screen crashes. The most stable setup I’ve managed so far is about 200 points per graph, anything beyond that consistently leads to a hard fault (which seems memory related).My goal is to reliably support 5 graphs × 700 points on the same screen. I’m trying to understand what could be causing the crash, whether it’s heap or stack limitations, frame buffer constraints, or something else in the graphics pipeline. It would be helpful to know how to narrow this down effectively.

Hello,at the moment i try to read correct accelerometer data with a STM32L010C6 Microcontroller from a accelerometer sensor BMA530. The connection is via I^2C (SDA and SCL) and i programm the Microcontroller with a ST-LINK V2. I took a code from gitHub Platform boschsensortec/BMA530_SensorAPI and changed it because in the common.c data i can´t use the coines commands because the STM32L010C6 needs STM32 HAL-Functions because Bosch use other Hardware as STMicroelectronics. The dev_addr2 = (0x18 << 1) see at https://sourcevu.sysprogs.com/stm32/HAL/symbols/HAL_I2C_Mem_Read#:~:text=SourceVu%20STM32%20Libraries%20and%20Samples,information%20for%20the%20specified%20I2Cand i got it from the BMA530 Datasheet - The default 7 bits I^2C address is 0x18.The Mem_addr = 0x18, i got it from the BMA530 Datasheet. 0x18->ACC_DATA_0 -> Read-only acc_x_7_0. In the BMA530 Datasheet at the Connection Diagram there are two resistors which i don´t have at my board.

Dear ST community, I'm reviewing the Vac sense circuit of STEVAL-7BIDIRCB, where the circuit uses a resistor divider to generate a low voltage of VACN and VACL for MCU. I simulated this section of circuit in LTspice, and here is my result : My Vac input is +/-256V sine waveform and VACL that I'm measuring is +/-900mV sine waveform. Based on my calculation this is a simple voltage divider and I should see +/-1.8V sine waveform. Why am I seeing 1.8V/2 = 900mV ?   I did some research and my understating is that when there is an equal resistor network each side of AC source ( N and L), Vac IN  becomes half ( 256V -> 128), but I don't understand how it is possible when my Vac input is 256V ?   

Hello support team, I just received a new AEK-COM-10BASET board and trying to connect Lauterbach debugger with License module for MPC55xx. Question : How can I connect to the board through Lauterbach debugger & SW? Currently the SW (TRACE32) shows error message when I press "Up" button. I have no idea why such "Target Power Fail" error or "Power Down" message is appeared.Also I checked below 11 pin and the measured voltage is 3.3V. The jumper (switch) configuration I made are ;JP1~JP7 : closed = shortJ13, J14 : I tried both 1-2 and 2-3 connection Any comment is appreciated, thanks! Best regards,apap

I'm back, and working with the stm32g070rb chip. I did prototyping on a nucleo board based on the same chip (split the st link and nucleo board), and wired the ST Link to the microcontroller with the following connections I used open-ocd for flashing code to the nucleo, and it worked flawlessly. Based on the wiring, I made the assumption that this'd translate directly when developing the PCB.   (picture of the PCB and the schematic) When I tried to make the same connections, and tried to flash, I'd get the following issue   ```bash Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.Info : The selected transport took over low-level target control.

Hello to whom this might concern,I was recently experimenting with STM32C011J4M for a small hobby project (I am trying to fit into a about coin size) and want to comunnicate with other chip over I2C. Due the size of the package I cannot use debugging to find core of the issue, so I used multimeter and legs 4 to 7 as signal outputs. I let CubeMx to generate signal configuration and try to use PA8 as output signal (overlaping with PA11[PA9]). The resulting behavior is that the physical leg 4 is stuck on 1.2V and output is not detectable. If I leave PA11 set as analog-nopull, but remove PA11 from 'HAL_SYSCFG_SetPinBinding' the output becomes readable. From rading on the other pins, I can see, that the communication doesn't work. The I2C is also on overlaping pins (default generation put the pins on PC14[leg 1] and PB6[leg8], which also overlaps with programming connections). I try to communicate with lp5817 and am wondering, if I should also remove pins PB7, PA14 and PC15 f

I've noticed, that the new STM32C5xx family is not present in the STM32_open_pin_data repo. I know why (MX2 vs MX), but ST, please, keep updating this repo with the new families' data. It's a valuable database for third party tools used to allocate pins in various STM32 designs. Thanks, JW

Hello,   I may have found a bug related to the STM32C092GCU6 MCU and the FDCAN peripheral.   I created a new project and experienced issues with FDCAN reception: no RX messages were received, and the callback HAL_FDCAN_RxFifo0Callback() was never triggered.  After several days of troubleshooting, I discovered a possible mismatch between the startup file and the generated interrupt handler names.  In startup_stm32c092gcux.s, the following interrupt vectors are defined:  .word FDCAN_IT0_IRQHandler /* FDCAN global interrupt 0 */ .word FDCAN_IT1_IRQHandler /* FDCAN global interrupt 1 */   However, when generating code with STM32CubeMX, the following interrupt handlers are created in stm32c0xx_it.c:  void FDCAN1_IT0_IRQHandler(void) { HAL_FDCAN_IRQHandler(&hfdcan1); } void FDCAN1_IT1_IRQHandler(void) { HAL_FDCAN_IRQHandler(&hfdcan1); }   As a result, the startup file expects FDCAN_IT0_IRQHandler / FDCAN_IT1_IRQHandler, but the gen

Hi I am trying to figure out these VCAP conections.From the datasheet I could look like they are internally connected together, for this reason could avoid routing these three pads together on my board.Can anybody confirm that is the case?Thank you.

Hi Community, I am using STM32H745I-DISCO board and generated a TouchGFX project and attempted to flash/debug from CubeIDE. The flashing process fails during the erase stage. Observed Errors Initially: “Error: failed to erase memory” After enabling external loader (without initialization): Erase still fails After enabling external loader with Initialize = true: “Failed to initialize external memory” “Error in initializing ST-LINK device” In CubeProgrammer: External flash is detected when selecting loader MT25TL01_STM32H745I-DISCO However: Mass erase fails Sector erase also fails Error message: “Sector erase operation has failed… please verify flash protection”  I am using STM32CubeIDE v1.18.1 and STM32CubeProgrammer: v2.16.x I have attached screenshots. Can someone help what could be the issue? Thanks.

Hello Team,Believing STM32H5 series is most secure Devices , just doing comparision between H563 and H573 security aspects.Just to know PSA Certified Level 3 and SESIP will also applied to H563 device as well ( being into same Family ) ? We are more concern about firmware protection against Physical and side channel attacks.    

Hi，   vl53L0x goto sleep and wakeup to reduce power.  I used single_mode,program as follow:   I find add          sensor_init(dev,vl53_mode);            //activa  The measurement time was 600 mS. long more than not add  this function？  how  to reduce the time?      

Hi, When performing two measurements per second, how can the power consumption of the VL53L0x be reduced? Is a single measurement or continuous timed measurements preferable? I adopted continuous timed high-speed measurements, setting the measurement duration to 22 ms with a 900 ms interval between measurements, resulting in an average measured current of 19 mA (according to the specification). Based on this, I calculated the average power consumption.(22 mS × 19 mA + 5 μA × 878 mS) / 900 mS = 0.4693 mA. I don't understand why others can achieve 20 μA.

Hello everyone,I am working on my bachelor thesis about sensorless Field-Oriented Control (FOC) for a three-phase BLDC motor.At the moment, I have a NUCLEO-F303RE board, a small BLDC motor, an ESC, and a power supply. I have already generated and measured PWM/SPWM signals from TIM1 channels on the STM32, but I understand that using an ESC with a 50 Hz throttle signal is not the same as directly generating three-phase PWM for FOC.For this reason, I am considering using an X-NUCLEO-IHM07M1 motor driver expansion board with my NUCLEO-F303RE board.My question is:Can the NUCLEO-F303RE + X-NUCLEO-IHM07M1 combination be used for a sensorless FOC thesis project? More specifically, can this board act as the required three-phase motor driver/inverter stage so that I can implement or test sensorless FOC with STM32 Motor Control SDK or my own code?I would also like to know whether this combination is supported by STM32 Motor Control Workbench / MCSDK, or whether I should use another Nucleo board o
