I'm using a NUCLEO-H755ZI-Q board. I tried to read following address.TEMPSENSOR_CAL1_ADDR (0x1FF1E820UL)TEMPSENSOR_CAL2_ADDR (0x1FF1E840UL)But I can't. it causes HardFault interrupt.I also tried to read the area from Debugger.Debugger said Failed to execute MI command:-data-evaluate-expression *((short*)0x1FF1E820)Error message from debugger back end:Cannot access memory at address 0x1ff1e820 But it is possible from Cortex-M7. I tried other System Memory area, But I can't.I think Cortex-M4 cannot access System memory area without special sequence.How do I access the area form Cortex-M4? Someone, please help me.

We need some help with cable replacement feature. Our project using WB1M as a client device, sharing data over UART. Android application must be server. STBLESensor_Android source code not include any sample code with Cable replacement feature. Were we can get one?

I'm using the AWD (STM32G0B0CE) with the HAL_ADC_LevelOutOfWindowCallback(), which works fine.For not blocking the MCU completely, I'm disabeling the AWD-IT inside the Callback when fired for about 500ms:LL_ADC_DisableIT_AWD1 (ADC1);After the 500ms elapsed the AWD-IT is enabled again:LL_ADC_EnableIT_AWD1 (ADC1);This only works fine for about 2 times:Start -> Fire IT -> DisableIT-> 500ms-> EnableIT -> Fire IT -> DisableIT-> 500ms-> IT stays completely disabled, though enabled again.Any idea what I'm missing?Thanks.

What's the max DC powerline voltage I can use with the X-NUCLEO-PLM01A1 expansion board?  Asked another way, what's the max voltage I can connect to the PLM_CONNECTOR C1?

Hello, @STTwo-32  I am working with the NUCLEO-WB05KZ (MB1801 + MB2032B target). I received two boards from the ST eStore. One board works fine: STM32CubeProgrammer detects the target, and I can erase/flash/debug with no issue. The second board initially connected once, but after flashing a BLE firmware example via STM32CubeIDE, the target MCU no longer responds. Symptoms: ST-LINK is enumerated correctly in Windows (Virtual COM Port visible, target voltage ≈ 3.28 V). In STM32CubeProgrammer: “No STM32 target found” or “ST-LINK error (DEV_TARGET_CMD_ERR)” Cannot connect even when selecting SWD + Hardware reset, lowering SWD frequency, or holding RESET while connecting. Tried with BOOT0 jumper set to “Bootloader” and with “User Flash,” no success. ST-LINK firmware is up to date. Jumpers are in default positions: JP1=5V_STLK, JP2=ON, SW1=3V3. What I already tried: Multiple USB cables and ports. “Connect under reset” procedure (RESET held while connec

Hi,I have a project with TouchGFX based on STM32N6570-DK.In STM32CubeMX, once I tried to add X-CUBE-AI, I got stuck, and the error is appeared as shown below.What does it mean?Once I removed the TouchGFX Graphic Application, the X-CUBE-AI can be enabled, but the generator removed MX_TouchGFX_Init() etc.Are there any side effects, if I restore the TouchGFX code manually?And I’m curious — why does this limitation exist?Regards!

Hi! My situation is the same as post provided here: https://community.st.com/t5/edge-ai/getting-error-quot-analyze-fail-on-the-ai-model-quot/td-p/55309Is there any solution to this problem? Also, I am using the STM32F407G-DISC1 board with a Mac with M3 Pro Chip.Thanks!

Hello all, I have been working on a keyboard PCB with an STM32F103, and I have started trying to program it with the STM32duino bootloader however, I have been unable to connect to the chip. This is my first time using the STM32CubeProgrammer with an ST-Link V2. I have verified the voltage across several points in the PCB. I have previously used similar designs with STM32F07 chips and had no issues.   Most of the time, I get an error of "No STM32 Target found" and sometimes I get the error "ST-LINK error (DEV_TARGET_CMD_ERR)". I have tried my best to look at past posts on the forum, but none of the solutions have fixed my issue.  I am happy to provide extra measurements and provide more information. Tips on how to troubleshoot this are greatly appreciated. Thank you in advance!   Schematic and PCB screenshot.

I am programming a custom board using STM32L562. While trying to connect the debugger using STM32CubeIDE I get the following error: Verifying ...Error: Data mismatch found at address 0x08001000 (byte = 0xFF instead of 0x0E)Error: Download verification failedEncountered Error when opening C:\ST\STM32CubeIDE_1.13.1\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.1.0.202305091550\tools\bin\STM32_Programmer_CLI.exeError in STM32CubeProgrammerShutting down...Exit. Besides, when I am trying to erase the memory with the programmer it is impossible.Does anybody have any suggestion?

Hello,I have a problem with the configuration of LAN8720A with STM32MP151.

Hello,I've got two NUCLEO-STM32H7S3L8 boards and started playing around with those. I created a project in STM32CubeIDE and used the standard template for the board with the generated example data. STM32CubeMX generated the "Appli," "Boot," and "ExtMemLoader" projects, but they seem to have some errors. Here's what I found so far:"Appli"-Project:This line of generated code: #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */This led to this compiling error:../Core/Src/eth.c:36:58: error: missing '(' in expression36 | #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */| ^../Core/Src/eth.c: In function 'MX_ETH_Init':../Core/Src/eth.c:73:22: error: 'DMATxDscrTab' undeclared (first use in this function)73 | heth.Init.TxDesc = DMATxDscrTab;| ^~~~~~~~~~~~../Core/Src/eth.c:73:22: note: each undeclared identifier is reported only once for each function it appears in../Core/Src/eth.c:74:22: error: 'DMARxDscrTab' undeclared (first use

Hey,I am using the stm32wb55rev6 boards as the client and server to send and receive the data.i am able to establish the connection between the server and the client.How can i be able to send the data from the server to the client using the usart1.Do i need to create a new  task in the sequencer using the util _regtask or is there any document related to that?

Peripheral: QSPIBug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for athreshold level of 23-bytes, the actual value is 0x06 corresponding to a threshold level of 7-bytes.Encountered on: STM32F723IE, STM32F746NG and STM32F767ZIComments: Checked the errata data sheets for the above processors and there is no mention of the bug.Request: Please can anyone confirm that this is indeed an undocumented hardware bug.

Has anyone used those BIG KEY button modules before? I’m trying to hook one up to an Arduino, but I’m not sure if I’m wiring it right since the signal seems stuck low. Do they normally need a pull-up resistor or should it just work out of the box?

Dear all,I have the STM32N6570-DK ,MB1860B  version . I'm trying to follow the procedure to flash the .bin files. The programming seems ok, but when I reboot the kit, there's no application... the screen is inactive. However, I can successfully flash the demos stm32n6570-dk-ai-demo-v1-0-0 and N6_OoB_v1.3_single_hex.the link: x-cube-n6-ai-h264-usb-uvc Applicationhttps://github.com/STMicroelectronics/x-cube-n6-ai-h264-usb-uvc/blob/main/Doc/Program-Hex-Files-STM32CubeProgrammer.md  Can you help me ? Cheers Emmanuel

Hi Sirs,                I want to buy an NFC WLC evaluation kit similar to the one shown in the picture I posted. Where can I buy?

The L6920DB temperature rating is not specified in the datasheet. However, it gives the temperature data as Max Tj=150C, Thermal resistance is 180C/W. Based on Tj=Ta+Pd*ThetaJa, if Ta=85C, then the Pd allowed in this temperature is very low. Is L6920DB rated temperature range specified as -45C to 85C?

Platform: macOS 11.7.10 (BigSur)   I wanted to try out the recently announced STM32Cube plugin for VSCODE. Did so but from my understanding I have to install/configure STM32CubeCLT within VSCODE. Not knowing whether I had installed it with STM32CubeIDE already I downloaded the package (again?). After the installation had run  successfully I went into VSCODE to configure STM32CubeCLT.An installation directory has to be specified. I have no idea, where this directory can be found. Can anyone help?

Hello,I am planning to develop a small low-power wearable device using the STM32WB05KNV6TR.My goal is to use the STM32WB05KNV6TR as a standalone MCU while implementing BLE communication.From what I have found, this IC seems to be often used only for BLE communication, so I would like to clarify a few points:Can the STM32WB05KNV6TR be used as an MCU that runs logic using peripherals such as ADC and SPI, while also handling BLE communication at the same time?If it is possible, which development board would be suitable for testing the STM32WB05KNV6TR before hardware development?I purchased the NUCLEO-WB05KZ board, but it seems to be in a module form (around 20x10 mm in size) instead of just the IC. Is this normal, or did I purchase the wrong version?On the other hand, the IC on the STM32WB5MM-DK Discovery Kit looks like an appropriate size. Would this board be a good option to use?Thank you in advance for your support.

Has anyone had success with the CMSIS-DSP arm_rfft_q31 or other of the M55 HELIUM MVEI/MVEF enabled CMSIS-DSP functions on the STM32N6? Is there a functional FFT example or STM32CubeMX project available? The STM32N6 FE 1.2.0 example CORTEX-HELIUM does not seem to utilize CMSIS-DSP.Whenever I try to utilize the CMSIS-DSP FFT-functions, I am experiencing hard fault when entering the arm_rfft_q31, function, if the M55 HELIUM MVEI/MVEF support is enabled.My FSBL project builds successfully and I am currently using ARM_MATH_AUTOVECTORIZE as a temporary solution, with limited performance.Please let me know for working examples, tips, or known caveats of using CMSIS-DSP with HELIUM MVEI/MVEF on STM32N6. I am looking for proof, that the STM32N6 MVEI and MVEF are functional and supported with CMSIS-DSP. Thanks! 

I'm running the CubeMX-generated lwIP implementation on an STM32H723. Memory addresses and configuration has been modified according to what is described at https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308Now when running this implementation, I stumble upon different illegal memory accesses where data is located in memory areas outside of the addresses of range 0x30000200 .. 0x30000200+32232.This happens more or less randomly. When I add some own address-checks at one position in code to ensure a pointer is in that area, lwIP crashes at an other position. So this looks like some memory leak or some other fundamental problem.Next I enabled MEMP_SANITY_CHECK in lwIP settings to track down these problems. With that, immediately on connection of an external client to my server, I end up in a failed MEMP-sanity check:HardFault_Handler() at stm32h7xx_it.c:85 0x8002f10 <signal handler called>() at 0xf

Hello, I am using p-nucleo-wb55. I have a code with an RTC alarm interrupt triggered every 5 seconds. In the ISR, I set a sequencer task that sends a message via BLE. I have enabled the LPM as I want the MCU to enter sleep mode while it isn't working and only wakeup with the RTC alarm. I realized that the MCU doesn't stay in the sleep mode and when I debug, I realized that it wakes up so fast as the IPCC RX Interrupt is triggered continuously with high frequency.How can I control this, knowing that I don't need the MCU to do any task through those 5 seconds, I just want it to sleep and wakeup only after 5 seconds. Thanks in advance

Hi,We have duplicated the design onto our own NFC tag, copying the same antenna design onto a flexi pcbWhat should be the tuning capacitor for this coil be for NFC ?If thats not available, what is the inductance value of the antenna so we can try and calculate it ourselves. Ultimately we will tune it but we would like to start with at least an approximation
