Hi there, I am using and STM32F469-disco board and want it to communicate via SPI2 with a Battery Management System. When launching only the BMS task it runs perfectly, the communication is stable and I can read cell voltages and temperatures through SPI2 line. The thing is that when adding touch gfx task (uncommenting the initialize of the kernel) it runs the BMS task as well as Touch GFX task but the BMS task does not work correctly, it does not communicate with BMS. The same code, same task, but adding Touch GFX task creates a conflict that does not lend the SPI2 communicate with other devices. In theory, the pins for SPI2 (PB14 and PB15) are free of use. I also tried to disable interruptions when reading BMS in BMS task (__disable_irq()) but does not work neither.Could someone think of a solution, or testing to know where is the problem?Thank you very much!PD: I would say that both Cube and Touch are updated to last versio

Hello Team,We are currently attempting to perform a silent installation/uninstallation for the application “SetupSTM32CubeProgrammer_win64.exe” on our Windows 11 devices to meet business requirements. Despite trying multiple silent parameters and installation switches, the installer continue to launch in interactive mode but does not proceed silently. This installation is required to support ongoing business operations, and we would appreciate your guidance or confirmation on whether silent installation method is available for this package. Kindly advise us on the recommended approach or provide alternative solutions to help us to achieve this.Thanks

I was performing a firmware update to my board when the board lost connection to my computer. Ever since then I have been unable to connect to the board. I tried going through STM32CubeProgrammer to perform a connect under reset, which just says "Error: Problem occurred while trying to connect". I have also attempted to hold the reset button while performing a full chip erase but I receive an error: must connect before performing action. I have all my jumpers in the correct place and even tried jumping BOOT0 while performing the connect under reset. I would love some help from someone who has possibly been through this before, thank you. 

 Hello I'm trying to flash data on a large block, but I've seen that the current code stops with FlashErase or FlashProgram functions.So I tried flash control in two ways and none of them worked.1. divide separate section to flsh areas2. use the secondLargeBlockSelect parameterThis is the code that was trying the second method by separating separate sections on B0F11 and B0F12 Block.This way, it goes to FlashErase, but it seems that FlashProgram is experiencing an error.I feel like the SetLock part is not working correctly. 

Hello @ST Community,I am working on a project with the STM32F746NG board. In this project, I want to communicate with a PLC using the EtherNet/IP communication protocol. To achieve this, I plan to integrate the OpENer stack into my project.I am looking for guidance on how to properly build and port the OpENer stack to the STM32F746NG board and how to test it to ensure it communicates correctly with the PLC. Any examples, step-by-step instructions, or references would be greatly appreciated.Thank you in advance for your support!

Hello,I'm in the process of moving from MP1 to MP2 on my device. The latter, used STPMIC1 that suffered the startup problem as described in AN5861 and I had to go thru a re-design to include the latching circuit on my PCBA.Can anybody confirm that this issue is gone for STPMIC25 that I will use for MP2?Thanks in advance,Daniel

I'm trying to get the Debug Authentication provisioning to work. I managed to write it from within the application, but then I found the errata sheet(es0565-stm32h562xx563xx573xx-device-errata-stmicroelectronics.pdf) which states otherwise:"Chapter 2.2.35: Debug Authentication provisioning cannot be done from the application when TZEN is disabled" I tried to do the provisioning with RSSLib->DataProvisioning(), as mentioned in the errata sheet, but I end up getting a hardfault.I'm using the nucleo-h536zi-board, trustzone is disabled.  RSSLIB_DataProvisioningConf_t a; a.pSource = sData; a.pDestination = (uint32_t *) (0x0FFD0100); a.Size = 0x60; a.DoEncryption = 0xCACA0AA0U; a.Crc = 0; uint32_t c = RSSLIB_PFUNC->NSC.DataProvisioning(&a);Since the CRC is not correct, I expect to get the CRC error instead of a hard fault. Is ther

Hi. i have a 743i eval board . and i've gone through the touch gfx examples (i'm not experierenced in c++ ) and i've found other examples ive worked though .. The project i'm on revolves around receiving CAN data and displaying on LCD and also touch screen button / external buttons that send messages back.  i've taken my button press example (controllers tech adapted to my board) this turns the display backlight on and off - so i know i can have external control.  i also have a a can example i've split in to a can.c can.h and added to the project (set up the interrups in cube ide and added the callbacks) .. but with breakpoints on the call back when i send a message nothing happends. After looking at webinars etc.. i'm guessing the rtos has got to schedule stuff so i may have to go back a step or 2 and re-look at those. but can't find the code to look at from the ST webinar - had display turning on external led and doing animation from a button . if anyone can shed

Hi, Every time I try to connect the eval kit to the GUI I get this error:This board doesn't reply properly to connect !Can anyone tell me how to solve this problem.  I have made sure that the correct COM Port and baud rate is selected. Also, the power indicator LED is ON and the RED LED is flashing. Your help is greatly appreciated.Regards,

Hi all,I’m currently using the EVSPIN32G4 development board for a drone project. I’m controlling motor forward and reverse using ST Motor Pilot.I’ve noticed that when switching from forward to reverse, there’s a short pause before the motor starts spinning in the opposite direction.Is there a way to implement a seamless transition between forward and reverse motion so that the motor can switch direction without this stop?Thanks in advance for your guidance!

What is the sequence and APIs to erase and program the Engineering bytes?There are APIs to handle Main flash, and APIs to handle OTP, but it is not clear how the Engineering bytes should be handled.Thanks

Hey everyone, I am trying to derive the internal gate resistance (R_Gint) of STP150N10F7. Can anyone help me with the calculation please. https://www.st.com/resource/en/datasheet/stp150n10f7.pdf   Regards,Vamsi.  

Hello everyone,I’m working with an STM32WB55 microcontroller with BLE stack. I use also low-power modes in my app. Before entering a low-power mode, I set an RTC ALARM_A to wake the system up at a specific time. The device then enters either Sleep or STOP2 mode with the RTC enabled.However, I’m noticing an issue where, when in these low-power modes, the RTC ALARM_A does not seem to wake the device as expected. The timing appears to freeze or behave unpredictably, and the alarm sometimes triggers late or not at all.Here is the output just before entering sleep mode with the configured alarm:Current time vs Alarm RTC Settings:(PREDIV_S = maximal SubSec = 32000)| Field | Current (Cur) | Alarm (Alm) ||------------|------------|--------|| SubSec | 7234     |  6594|| Sec       | 21          | 21      || Min       | 0

Greetings!I am using the STM32U031 with STM32CubeMX HAL as an SPI Slave and would like to receive data that has variable length (max 50 bytes). I am using software NSS and my current approach is to start a DMA Rx/Tx transfer (using HAL_SPI_TransmitReceive_DMA) of the maximum expectable length when NSS goes down (in the corresponding GPIO callback) and to abort the transfer when NSS rises again (using HAL_SPI_Abort). From a functional perspective this approach works, but the abortion of the Transfer currently takes about 1.4 ms (at 8 MHz MSI Clock). As a result,  the answer to the Master is not ready when it clocks again. Is there anything I can do better / different to improve the timing?I know that using HAL_SPI_Receive_DMA instead of HAL_SPI_TransmitReceive_DMA for Rx would reduce the time required for aborting the transfer, but then it seems that I have no control over the data that is transmitted while r

Hi,I want to integrate on the same PCB both a STM32WB5MMGH6TR and a STM32WL5MOC. Are there any issue in terms of RF interference? Are there any shielding recommendations to avoid problems while both modules are transmitting?ThanksMatteo

Hello @Community, I am working on the STM32F746NG board. In my application, I want to communicate with a PLC using the EtherNet/IP communication protocol to exchange real-time data. The problem I am facing is that my board does not respond to ping when FreeRTOS is enabled. Without FreeRTOS, the board is pinging correctly. Has anyone faced this issue before? If yes, please guide me on how to resolve it. Any suggestions or solutions will be greatly appreciated. Thank you!

We have a working production firmware for the STM32H7B3 that uses a Winbond W25Q01JVZEIM external flash using QSPI in memory-mapped mode to store data and assets for a TouchGFX and other applications.Now, due to internal flash limitations, we are attempting to execute some code directly from the same external flash. As a starting point, we created a simple test function to run from external flash:__attribute__((section("ExtFlashSection"))) void test_ext_flash_func(void) { volatile int x = 1; x++; }The rest of the application continues to run from internal flash. However, when this function is called, the MCU enters a continuous reboot loop. We have added Hard fault handler but couldn't see any prints for different register values.Current ConfigurationLinker ScriptMEMORY { ... OSPI (xr)
