Hello everyone,I am experiencing a strange issue with the Ethernet interface on my STM32F207VC.Problem DescriptionAfter programming the firmware using STM32CubeProgrammer v2.12.0 with an ST-LINK debugger, the application works perfectly:- The board responds to ping.- My PC client communicates successfully with the TCP server running on the STM32.- Ethernet communication is fully functional.However, after performing a power cycle, the Ethernet stops working:- The board no longer responds to ping.- TCP communication fails.- The application itself appears to be running, but the Ethernet interface is non-functional.Hardware Details- MCU: STM32F207VC- Ethernet interface: RMII- Default STM32 RMII pins are used.- Programming/Debugging: SWD (ST-LINK)- The board has an external 8 MHz crystal, but in STM32CubeMX the MCU is configured to use the internal HSI clock (HSE is not enabled).- The Ethernet PHY has its own 25 MHz crystal and provides the required 50 MHz RMII REF_CLK to the STM32.The exac

Hello,I am looking for a BLDC motor controller with Hall sensor and Encoder interface. Hall sensor is used for commutation and Encoder will be used for position control. I could not find a motor controller with above mentioned interface. Can you suggest a suitable controller?Thanks,Anand

I am working on camera integration with both the STM32MP257F-DK and STM32N6570-DK development boards and would appreciate some guidance from the community.My setup Boards: STM32MP257F-DK STM32N6570-DK Camera sensor: Suggest One camera Sensor for both, currently I have VD55G1 and VD66GY Software: ST OpenSTLinux (Yocto) on STM32MP257F-DK My questions Is it possible to interface a camera to the STM32MP257F-DK using the DCMI peripheral, or is MIPI CSI-2 the only supported camera interface for this board? For the STM32N6570-DK, what is the recommended approach for connecting a camera through DCMI? Are there any supported camera modules or reference designs? Are there example projects available for image capture using DCMI? If the camera sensor provides only MIPI CSI-2 output (such as the VD55G1 and VD66GY), is an external bridge/converter required to use it with DCMI? Are there any ST application notes, reference designs, or GitHub examples demonstrating camera i

after selecting the pins from cube MX, it will generate code in c but i want that in cpp

It appears that the longest spi operation that could be used to access the LSM6DSV (and related parts) would read a single fifo entry (7 bytes) and it is not possible to read all the available fifo entries in a single dma operation.  Am I missing something? Geoffrey

Hello, I'm trying to program a custom board equipped with an STM32WBA23CE.I've tried wiring it from a Nucleo board (MB1801D), but the programming is failing.CN3 pin5 -> Custom Board VDDpin9 -> PA13pin11 -> PA14Even when I press Connect in CubeProgrammer, an error dialog appears. It works normally when I disconnect the wiring to the custom board, so it doesn't seem to be an issue with the application or the Nucleo board.The custom board does not have 32 kHz support.Are there any resources or descriptions that might be helpful regarding this method?

I purchased a brand new Nucleo board. plugged it into my computer, USB device detected, please update firmware; yes; then the process stopped “Error 33” Now my BRAND NEW  nucleo board seems bricked.  Is there any recovery mode?  I have tried several times on STM32 Cube Programmer; The board is detected,      Does anyone have any suggestions? - This does not bode well for my first introduction to ST. What a flaky system. I have changed cables etc, several different combinations, changed USB ports, rebooted, all of the standard stuff.  It seems as though the Nucleo board’s serial number is being detected.  The firmware update process starts, runs for a few seconds, several red LED flashes, then halts and gives error 33.  

I’m looking for a replacement of MT53E1G32D2FW-046 WT:C because it’s out of stock.So, I have found Samsung K4FBE3D4HM-TFCL LPDD4. From what I can see, it’s compatible with MT53E1G32D2FW-046 WT:C:Same voltage Same package Same pinout Single rank Follows JEDEC standardAre there anything else I need to know before making an order of that LPDDR4 memory?

Why does STM32MP257F-DK not having EMI-filters on RX lines for USB 3.0?Can it be like a common standard that the transmitter TX should always have:AC capacitors ESD protection EMI-filteringAnd the RX does not need anything of those, because it’s assuming that their transmitter already having these implemented?This picture is from mb1605-mp257f-c01-schematic.pdf 

Hello,I noticed that in the STM32Cube_FW_H7_V1.13.0 distribution, the folder \Drivers\CMSIS\DSP\Lib has disappeared.Is there a document available that explains how to compile these libraries, and what are the options and defines to set for an STM32H743?Thank you.

I’m starting FOC code generation for H5 using MCSDKBlocks I am configuring in MC Workbench include , STMH563ZI (Nucleo Bd) and IHM07M1 (Power module), and motor.  I noticed the PWM configuration is not for general purpose, it is specifically configured for L6230 in IMH07M1.But I’d like to configure PWM for general purpose,  such as for the STEVAL-LVLP01 board I have evaluated already, is this possible? Please let me know and thank you for your consideration.

Dear Team,I would like to request access to the Amazon FreeRTOS code supporting OTA functionality on STM32 platforms.I am currently working with STM32 boards and am specifically interested in evaluating and developing OTA-based solutions using Amazon FreeRTOS. I understand that access to this codebase is currently restricted, and I would like to be considered for whitelisting.Requested Access For:Amazon FreeRTOS OTA code for STM32 platforms (e.g., B-L475E-IOT1A, NUCLEO-H743ZI, P-NUCLEO-WB55, STEVAL-STWINKT1B, X-NUCLEO-BNRG2A1, STEVAL-STMODLTE)Purpose:I am working on embedded development involving BLE and cloud-connected applications and would like to integrate OTA update capabilities into my STM32-based projects.Please let me know if any additional information is required to process this request.Thank you for your time and support.Best regards,Ravi

Hi ST expertSTM32G473cbt6 and STM32G474cbt6 are pin-to-pin compatible, can their software projects be designed into one project?

Hello everyone.I will use my MCU to acquire big amounts of analog data and transfer them to a host using UDP.As DTCM is 128K and SRAM1 is 368K I would like to store those data in SRAM1. As an exercice I’m trying to configure LwIP in SRAM1.I’ve followed many tutorials (MPU is, I beleive, set correctly) :with a cache protected region where all the LwIP data should be (normally it should only matter when I’ll run this program) I’ve also configure ETH to point to this area :And Lwip is also configured with this same areaAnd the flash script is also set :But when I compile the code directly after importing from cubeMX, I get :Data are not in SRAM1, they are in the DTCM.Am I missing something ? Do I have to set some options in the compiler ?Also I’m a bit surprised to see that 4 descriptors x 32 bits = 0xa0 (0d160) ??? Or F777 descriptors are 40 bits ?Thanks to anyone who will take some time to help me.Best regards 

Hi, i would like to use relative path to firmware. UI has option to enter “Firmware Relative Path” but only option is to select trough Browse dialog and resulting paths in cmake are absolute. There is no way to enter path manually, as UI applet for that is read-only.Also i have noticed, that clone of firmware without submodules causes CubeMX to error out with cryptic message on code generation.

Hi, i have custom cmake configurations in my project. I have managed to make a selection trough “CMake: Select Configure Preset”. Unfortunately it is really easy to debug wrong configuration on debug launch, as you have to remember to switch configuration from command palette.

I need to use 2 image sensors for tracking proposes, it would be nice if I could sync the two cameras.I see that provide configurable GPIOS with signals like PWM/ PULSE/ VSYNC/ START OF FRAME.Is there any application note/ reference design, on how to sync two image sensors ?  Do I need an external PWM for this? or one sensor can be master (to generate pulse) and to provide clock to Slave sensor?Also I would like to now if the two sensors can have the same clock source to sync MIPI clock.Thank you.

Hello,We are designing a custom board using the STM32MP157FAC1 device and need to provide one USB 2.0 High-Speed port.Kindly refer to the attached block diagram snapshot and review the proposed USB interface architecture of our custom board.Please verify whether the implementation is correct and let us know if any modifications or additional recommendations are required for reliable USB 2.0 High-Speed operation.Regards,PS 

 Hello,We use MB1551 TFM example project on our industrial board. For technical reason, we have modified the card entry point from USART1 to USART3.(TFM\TFM_SBSFU_Boot\Src\low_level_com.c, “COM_INSTANCE”)(TFM\TFM_Appli\Secure\Src\low_level_com.c, “COM_INSTANCE”)The log of SBSFU doesn’t appear on UART target.So next, we are trying to debug TFM SBSFU of a STM32U585 project as shown in this tutorial : We use the SBSFU script “regression.sh” and flash SBSFU, loader, secure and unsecure application with “TFM_UPDATE.sh”.The JTAG connection works correctly to open CubeProgrammer and read option byte for example.Finally, we set the tutorial debug configuration and launch the debug without error. Debug launch but stop with this message :After, we can only stop the simulation or terminate it.  We have couple of questions.First of all, can we come to the conclusion that our MCU is booting ?Secondly, Is it possible to change USART1 to USART3 as we did ?Why do we have break point before the debug s

In position control mode, when the commanded angleand motion time are not properly matched, the motor speed sometimes exceeds the maximum speed limit. For example, if the motor’s maximum speed is 3000 RPM, after executing the command the motor speed may reach 4000 RPM. Its not generating error that this motion cannot be executed.

Post edited by ST moderator to follow the community rule to post a code snippet: How to write your question to maximize your chances to find a solutionI need to use scan sequence of 3 ADC channel  and DMA transfer of the 3 ADC value .The 3 channel are:sConfig.Channel = ADC_CHANNEL_TEMPSENSOR;sConfig.Rank = ADC_REGULAR_RANK_1;sConfig.Channel = ADC_CHANNEL_VREFINT;sConfig.Rank = ADC_REGULAR_RANK_2;sConfig.Channel = ADC_CHANNEL_15;sConfig.Rank = ADC_REGULAR_RANK_3; but doing this the HAL_ADC_ConvCpltCallback is called only once. if I change the ADC_CHANNEL_15 with   ADC_CHANNEL_VREFINT  everything is working correct. Why ? 

I am using STM32H753ZI and trying to bring up Ethernet (LAN8742, RMII) using HAL + lwIP in NO-RTOS  mode. I generated the code using STM32CubeMX with ETH enabled (RMII) and lwIP enabled (WITH_RTOS disabled, static IP). The PHY link comes up and RJ45 LEDs blink, but the board does not respond to ping and no ARP entry is created on the PC (Destination Host Unreachable). I have placed ETH descriptors and RX buffers in D2 SRAM, enabled MPU and D-Cache, verified RMII_REF_CLK to PA1, selected the LAN8742 PHY driver, and I am calling MX_ETH_Init(), MX_LWIP_Init(), and processing lwIP in the main loop. The FreeRTOS-based STM32H743 Ethernet example works, but I specifically want a HAL-only .

Hello Team, We are currently investigating an issue related to the SPI communication between the STPM34 sensor and the STM32F4 microcontroller.At system startup, all values measured by the STPM34 remain stuck at zero. Even when voltage and current are injected using an OMICRON test bench, no measurement values are received or displayed.Several tests were performed:If we power up the system and confirm that the issue is present, then electrically restart only the board containing the STPM34, the communication recovers correctly and the measured values are no longer stuck at zero.We also soldered wires on one of the SPI buses (SPI1). Since there are two STPM34 devices on the board, two SPI instances are used to communicate with each sensor. The purpose was to verify whether the communication between the sensor and the STM32 was correctly established.Interestingly, simply soldering wires on this SPI bus makes the issue disappear for this instance. However, on the second SPI instance,
