Hello, I am using an **STM32 NUCLEO-N657X0-Q** board with the **B-CAMS-IMX camera module**. Originally, the board was working correctly. In **DEV BOOT mode**, I loaded and ran my AI model, using the B-CAMS-IMX camera sold by ST. The board connected normally to my laptop, and I was able to confirm that the AI application was running correctly by viewing the camera output and the AI object detection result on my laptop. I also changed the BOOT pins and confirmed that the same AI application worked correctly in **Flash Boot mode** as well. After that, I wanted to test whether the board could run from an external power supply instead of being powered through ST-LINK. So I changed **CN9 from 1-2, STLK power, to 5-6, VIN power**, following the description in the official NUCLEO-N657X0-Q documentation. Then I applied **7V from a DC power supply to the VIN and GND pins** of the NUCLEO-N657X0-Q board. I carefully checked the polarity and connected VIN and GND corr

Hi, can someone please check what is wrong here: CubeMX/CubeIDE generates an STM32WB55 linker/memory map that places .MB_MEM2 in an SRAM2 region that bus-faults after the installed wireless stack reserves/protects SRAM2.

Hello STM Team,I have been trying to get the GC2145 to work on the DK but no matter what i do i only get /dev/video0 but never /dev/media0I use Buildroot with the Linux kernel on ST's Github. I have followed this guide here: https://wiki.st.com/stm32mpu/wiki/STM32MP13_V4L2_camera_overview and i have all the Kernel modules needed activated.I know the camera is plugged in properly because the demo from ST works but there's no code or config that goes along that demo for me to find the issue, at least i could not find it.I will attach a little bit of debug info at the bottom if its any helpful:# dmesg | grep -i gc2145 [ 0.058299] /soc/bus@5c007000/i2c@4c006000/stmipi@14: Fixed dependency cycle(s) with /soc/bus@5c007000/i2c@4c006000/gc2145@3c [ 0.058443] /soc/bu

Hello Team, Hope you are well! Could you confirm if the following top marking on ST4SI1M0008SCIFW is correct? 8942310525 000000923 FN527 Many thanks! Robert

Hello,I used the SPV1050 chip to connect the circuit to the STEVAL-ISV019V1 evaluation board, and measured VSTORE to be 3.9V, which did not reach VEOC and naturally did not have LDO2 output. I use the STORE pin to power my sensor node load. May I ask which part of the energy I am using at this time is from the battery?Besides, how can I make VSTORE rise to VEOC? Why hasn't my VSTORE changed under prolonged exposure to light.Can the final LDO2 output supply power to the load, or can it only serve as a reference voltage for certain devices.Thank you for your reply.

There does not seem to be any way of viewing a debug variable in hex.The closest workaround is to prefix (void*) before the expression in the watch window. This is no good for viewing an array of hex digits like for example a CAN bus message.

Split from  ST87M01 : MAX length of the data returned by AT#IPREAD - which is solved.This is, indeed, a new question.Hello Didier,I have an additional question on this topic (I don't know if I should create a new post, but this question is very much linked to the previous one...) :- From the ST87MXX AT Command User Manual §9.8 AT#IPSENDUDP, the max IP frame size is 1400 bytes- But from ST87MXX TCP/UDP-IP Application Note §3.2 IP default parameters command, the max IP frame size is 1600 bytes,Is there a mistake in one of these documents, or is there something that I didn't understand ?Best regardsThierry

Hi, As per title I am unable to enter the System Memory bootloader when using the STM32C071FBP6N. Any assistance would be greatly appreciated. Following the notes in AN2606, i have configured pattern 11 (line 2) using the CubeProgrammer but when completing the reset with the Boot0 pin high it does not enter the bootloader mode and can tell this because my user application runs immediately after the reset occurs. I have been able to jump to the bootloader through my own firmware where I initialize the HAL and GPIOs and then check the status of the boot0 or other pins then manually change the PC and SP but wish to avoid this method as this should not be necessary. ------- I have followed the steps below: 1. Using a ST-Link I have successfully changed the option bits nBOOT_SEL=0; nBOOT1=1; nBOOT1=1; BOOT_LOCK=0 using the CubeProgrammer and have also flashed a basic UART output program which outputs to USART2 the whether the PA14

Post edited by a ST moderator. Please use English in this community. Please read How to write your question to maximize your chances to find a solution   手册上写着在高分辨率模式下功耗 90 µA，在低功耗模式下功耗低于 1 µA。可是我用示波器串联电阻抓出来的功耗接近1MA，并且未使用MCU配置传感器时功耗就已经接近这个值了。传感器通过开发板的3.3V接口进行供电。电路图如下所示，哪里存在问题呢？ Translation: The manual states that the power consumption is 90 µA in high-resolution mode and less than 1 µA in low-power mode. However, the power consumption I measured with an oscilloscope using a series resistor is close to 1 mA, and this value is already close to the power consumption even without configuring the sensor using the MCU. The sensor is powered through the development board's 3.3V interface.

I am working on SDRAM execution using FMC on STM32H563ZI (NUCLEO-H563ZI board) with external SDRAM connected through FMC interface. Our target is: Execute application sections from SDRAM Place heap and stack in SDRAM Enable automatic scatter-loading/copy from internal flash to SDRAM during startup We are facing an issue where: SDRAM initialization appears successful Manual SDRAM read/write access works in application runtime But automatic copy/scatter-loading from Flash to SDRAM during startup is failing Application execution from SDRAM is unstable and leads to HardFault/reset handler Below are the detailed steps and observations.

Is it possible to use the awesome MDF and/or ADF on STM32U5 with input data from RAM? I have not found any configuration for BSMX for this. One use case is an high performance external delta-sigma-demodulator (ADC) on SPI with proprietary data format (24 Bit per channel, MSB first, CRC etc.) for providing the sound data. Another use case is an LSM6DSV16XTR, also connected via SPI.

I'm trying to use _Atomic with 64 bit objects, but I get a link failure:undefined reference to `__atomic_load_8'The internet says I need to add an option to the link command:-latomicHowever, it looks as if that library is not included with the ST tool chain:cannot find -latomic: No such file or directoryHas anyone managed to get this working?There are a number of workarounds that could be used here, but it would be much easier to use the native C feature that's been available since C11.I'm using STM32CubeIDE V 1.18.1 with GNU Tools 13.3

Hello everyone! I have a problem with reterning ticks in line "measure_speed_rpm = speed_reference / LL_TIM_GetCounter(TIM2);". speed_reference is const variable and equals 15000000. When I looked at Serial Monitor, it's indicated: (picture)That's mean that LL_TIM_GetCounter(TIM2) returns '1' sometimes. Nothing in my code not calling void EXTI1_IRQHandler(void), except EXTI Interrupt. And the main question is - Why it reterns only '1'??? Not 2,3 e.t.c.Thank you for help! void

The STM32F415 transmit and receive lines are connected to the MAX3232 chip. The board also contains chips to control LEDs and read tokens, which are controlled by the STM32F415, and those functionalities work, but I am having issues with the RS-232 communication. I get nothing on the receiving end. When I hook up a scope to the transmit line for UART4 (pin 51) on the STM32 chip, it is always high (3.3 V) and nothing is transmitted. What could cause this issue?

Hi,I'm building a DC-DC converter with a USB-C output using an ESP32 and a STUSB1602 configured as a fixed 5V/3A Source (no PD stack).The problem: when I plug a USB-C cable into my receptacle connector, the FSM jumps directly from Unattached.SRC (0x08) to ErrorRecovery (0x13) without going through AttachWait.SRC (0x09) or Attached.SRC (0x0A). No alert is generated on the ALERT pin, and CC_DETECTION_STATUS (0x0E) stays at 0x00 the whole time — the chip never seems to detect Rd on CC1 or CC2, even though I physically measure a voltage drop to ~0.3V on CC1 when plugging.Hardware setup: STUSB1602 as Source, I²C 0x28 USB-C receptacle CC1/CC2 connected directly to the chip, no external resistors VBUS_SENSE upstream of the MOSFETs (connector sees no VBUS before attach)Software configuration: 0x28 POWER_ROLE_CTRL = 0x00 → Source 0x18

CubeProgrammer 2.22.0 under MacOS 26.4.1 is not able to connect to my NUCLEO-G431, with the log window showing:ST-LINK error (DEV_CONNECT_ERR)Strange thing is this only happens when I have a direct cable connection between the USB-C port on the Mac and the ST-LINK V3 USB on the board - it works as expected if I connect via a USB-C hub.VS Code is also not able to connect to the board to run a debug session without the hub, so I suspect this is an ST-LINK USB driver issue on the Mac.

Hi Community,  I'm a new Developer/ for ST Microcontrollers, Now Im currently using STM32H723ZGT6 (NUCLEO - 144). Im currently working on ethernet (LWIP), the ping is not working for this code that i have generated . I have seen some youtube channels but I cant rectify and make the ping, I have tried all the possible things like , flash linker script , enabling ICache , Dcache , using MPU(Memory Protection Unit), change them to static ip for both board and my PC and So on . I have tried but I dont know whether my code or my implementation is correct or not . Can anybody help me with this ?.. I have attached the file thats my code and how project. pls have a look into that.  Thank You. 

Hello STM32 Community,I am developing a system on the NUCLEO-N657X0-Q using ThreadX and NetX Duo and I am having a hard time to make the ethernet work. I want to implement a web server in my system but I cannot make the Ethernet communicate.Problem:I am unable to receive or transmit any Ethernet frames. The PHY link establishes successfully (from what I see on my linux terminal, autonegotiation completes, Link is UP, and the LEDs on the plug turns on normally), but pinging the Nucleo's static IP yields no response. Wireshark shows no ARP or ICMP packets originating from the Nucleo.Trying to debug, I see that the the MAC/DMA interrupt `ETH1_IRQHandler` is never triggered by incoming network traffic. It fires exactly twice during the initial board boot sequence(where, for what I understand, some DMA errors flag are raised), but remains compl

I am trying to interface STM32L432KCU6 with ADIN1110. Volktek IMC-553 media converter is used to bridge the MCU board with laptop. I am trying to send UDP data. But communication is not succesful. I have a custom project board with the MCU as well as a nucleo board. I tried on both. However I have succesfully interfaced STM32 with ENC28J60 and communicated with laptop over UDP. I am currently doing development in Zephyr. However if any one can support in Arduino/STM32 Cube or any other, I am OK. My intention is succesfully interface ADIN1110 with STM32 and communicate data and visualise in laptop.Thanks in advance.

Split from this thread  My firmware is based on this ccid usbd driver https://github.com/STMicroelectronics/stm32-mw-usb-device/blob/master/Class/CCID/Src/usbd_ccid.c . The issue that I face, the PC finishes receiving data immediately after receiving 256 bytes (10 bytes of header + 246 bytes of data). when I want to send to pc 253 bytes of data + 10 bytes of header (263 bytes in total) by splitting (64 bytes by 64 bytes) the PC finishes receiving data immediately after receiving the fourth chunk which is 256 bytes (10 bytes of header and 243 bytes of data), It doesn't wait for the fifth chunk, which carries the remaining 7 bytes
