Hello,I’m using the STEVAL-STWIN KT1B to log data. I flashed HSDatalog onto it and used the ST BLE Sensor Classic iOS app to log data and save it to an SD card.After acquisition, when I check the AcquisitionInfo.json file, I notice that "start_time" and "end_time" are always empty. I’d like to know how to automatically set "start_time" to the current timestamp when I press the Start button to begin logging.In the iOS app, I tried going to Settings → Nucleo Settings → Set node time and clicked to synchronize the mobile and node time. A window pops up saying "Sync Time - Sync Done", but after logging, "start_time" is still empty.Is there something I’m missing?Thanks!Best, Anthony 

Hi!I'm having a hard time trying to figure out the pinout from the datasheet for the M24M02E-F Eeprom.I plan to use the WLCSP5 package but the package information chapter and the pin description chapter paints two completely different pictures and I don't know which one to use. The pin indicator are in opposite sides. I suppose the package information is the most correct one but if I use that, how are the pins situated then? Simply just mirrored from the pin description image?Unfortunately I'm not alllowed to upload images but this is the datasheet:https://www.st.com/resource/en/datasheet/m24m02e-f.pdfPackage information is at page 44, chapter 10.4Pin description is at page 3, figure 3. Thank you

HelloI am trying to debug M4 firmware on my custom STM32MP157C board.I have a reference operating system built with yocto on which this works correctly.I have to build system with a changed configuration and debugging of the same firmware is not working.Of course I saw this video https://www.youtube.com/watch?v=YIhzzgJmop0When I click the Debug button, the application correctly uploads however it won't start.I get the message:Error in final launch sequence:Failed pre launchFailed pre launchFirmware remoteproc load failed, please:1. make sure that /lib/firmware on your target has space2. make sure that /lib/firmware has write accessOf course my target has space and write access - in other case file transfer will not be successful.Starting the firmware manually works ok with this commands:echo OpenAMP_raw_CM4.elf > /sys/class/remoteproc/remoteproc0/firmwareecho start >/sys/class/remoteproc/remoteproc0/state Question: how to determine more precisely what failed?Or maybe any hin

Hello Team,We are using the ST25R200 NFC reader with an AM64x series TI processor, for that we need the Linux kernel driver for ST25R200.Can you provide the link to download the kernel driver?Thanks,Dharmik

Hello STMicroelectronics CommunityI want to integration NFC functionality into Linux based system. But I did not find the st25r100 software package on the st official website. Like this.Can you provide me with a package or other download path? Thanks,Ivy7  

We are using the STM32WL55CCU6 processor and generating code for two cores. For GPIO it is not possible to specify which core will initialize the GPIO (of course, it is not necessary) but the code and definitions are not generated for any core.STM32CubeIDE Version: 1.18.0ioc file included...

When will ST support Lora Basics Modem and, perhaps, Relay, FUOTA? Thank you, Dana

Hello,I am new to the STM32N657x0H3Q MCU and trying to generate code from latest CubeMX with the following peripherals enabled:UARTEthernetDCMIUSBNon-secure region onlyHowever, after generating the code and compiling it in Keli, I am encountering multiple errors. Additionally, CubeMX shows a warning:"  - Generating AppNS project without AppS, compilation errors maybe generated."I am trying to understand why this issue occurs.Is there a strict limitation in this MCU series that requires defining a secure region?If not, how can I properly generate code with only a non-secure region and avoid these errors?Also, I am planning to buy the STM32N6570-DK board for my project.thanks.....

I have a question about the MEMS audio sensor MP23DB01HP. I think i already undertood that the output is a PDM, but my question is, how can I convert that to obtain a corresponding value in dB? Or some used unit? I have done the acquisitons, but know i don't know what to do with that values... Thank you in advance for your replies

I'm trying to make own dfu application on STM32F746G-DISCO board.I've already tested dfu function by using ST's DFU_Standalone demo example which is worked under USB device mode.Demo example is also provided upgradable sample application which is named as STM32746G_DISCOVERY_SysTick_0x08008000.dfu.I can upgrade this application by using DfuSeDemo.exe on windows 10 PC and It works well.But if i made a simple led toggle dfu application, It cannot run.In this case, i have used the same DFU bootloader. Just changed application.Below is what i modified for dfu application--------------------------------------------------------------------------------1. Changed app's flash location to 0x08008000 in STM32F746NGHX_FLASH.ld2. Changed VECT_TAB_OFFSET to 0x8000 in system_stm32f7xx.c.the board is always running in DFU mode even if there is no error by using DfuFileMgr.exe and DfuSeDemo.exeSo i checked flash's USBD_DFU_APP_DEFAULT_ADD(0x08008000) location by using STM32CubeProgrammer.It shows 0x200

Hi community,I have a problem that other people have also raised and I'd be grateful for help.I followed AN5361 and I watched this STM video on the same topic. First thing to mention is that the video and doc have different advice about whether the CM7 should Halt All Cores (Video advice) or not (AN5361 advice). Grrr!Now I've got that off my chest here's the problem in more detail.CM7 like this:  CM4: With that configuration when I launch CM7 first, then CM4, both pause as expected with CM4 in reset and CM7 ready to go. When I select both cores then click on the green go arrow, CM7 runs straight into this:Caused by the timeout expiring.If, alternatively, I configure CM7 like this:Then I can debug both cores, but they aren't doing a coordinated start as they should.I know that I could ignore the timeout error, but then the systems wouldn't be doing a coordinated start as they should.Any suggestions please?    

Dear ST Team,I am having difficulty finding the ULD library for the VL53L3CX chip. The complete library is too large for my chip's Flash memory, and the ULP library's ranging capabilities and accuracy do not meet my requirements. Could you tell me if there is a ULD library available for this chip, similar to the one provided for VL53L1? Thank you for your assistance.

I'm trying to use my NUCLEO-H753ZI board to send some message to my PC using UART. I read from the data sheet that USART3 is connected to the ST-LINK for the Virtual COM Port (VCP), and USART3 can directly transmit messages to the PC. However, in the configuration window, USART3 is greyed out and cannot be configured. Is this normal? If so, how can I send messages to my PC using this board?

Hello, I want to enable the secure connection key type as 'DEBUG' in STM32WB55 with my custom setup. The cube IDE does not allow this setting in the configuration of .ioc file. I followed this tutorial and added the following line in my code inside the definition of Ble_Hci_Gap_Gatt_Init() function, but it returns with error code 0x12 (Invalid HCI parameters). What am I missing here? static const uint8_t SC_KEY_TYPE_DEBUG = 1; static const uint8_t SC_KEY_TYPE_NORMAL = 0; ret = aci_hal_write_config_data(0x35U, 1, (uint8_t*)&SC_KEY_TYPE_DEBUG); if (ret != BLE_STATUS_SUCCESS) { APP_DBG_MSG(" Fail : aci_hal_write_config_data command - CONFIG_DATA_SC_KEY_TYPE_OFFSET, result: 0x%x \n", ret); } else { APP_DBG_MSG(" Success: aci_hal_write_config_data command - CONFIG_DATA_SC_KEY_TYPE_OFFSET\n"); }I am also following AN5270 for development, and the offset to set SC_KEY_TYPE seems to be correct. This is what I am seeing when I run the code: I made sure that CFG_

Hello, I am using STM32WB55 chip on my custom setup. I have configured my device in peripheral mode. I want to be able to accept / reject pairing requests initiated by the client device. I am following AN5270 for development. I have added code to set bit3 in SMP_MODE register to enable the generation of pairing request event. Although, the documentation says "SMP MAY generate the event". Why is that? The documentation also says that if I bypass the SMP, all the events that go to SMP will be transmitted to the application. However, what are the other events handled by SMP? I am not able to find a list of events handled by SMP. Is there any other documentation that I am missing? I also looked at an older thread in which the functionality to accept / reject pairing request did not exist. But since not it exists, do you have an example code where it actually works?Any help is appreciated!  Here's the old thread: https://community.st.com/t5/stm32-mcus-wireless/what-is-th

Hello, We would like to integrate LSM6DS3TR sensor.For that to happed we need SEE (Secure Execution Environment) framework drivers for Qualcomm based processors. Could you please supply drivers for that? It is urgent. Thank you.Best regards,Miha

Hi,I am using the ism330dhcx and lis2mdl and run the MotionFX  algo.the ism330dhcx data rate is 104Hz and the lis2mdl is set to 100Hz (sensor hub ODR set to 104Hz)should i run MotionFX  algo at 100Hz or 104Hz ?on ST examples, when the ODR is set to 104, the ALGO_FREQ is set to 100 !is this difference can generate wrong values on fusion algo ?i notice that if i run the magneto calibration at 104Hz, the calibration is never reachif i use 100Hz for magneto calibration and 104Hz (or 100) for MotionFX  algo it is workThank you,Sincerely.

HiI am not an IMU expert. My current task is to upgrade an old board which used LSM6DSL(gyro abd accelerometer ) and lsm303agr(Magnetometer) to caliculate orientation of a human head.As far as I can see LSM6DSV would be providing orientation data without gyro. So I dont need a magnetometer?When it comes to orientation data, what is the benefit of having a magnetometer? How does it come LSM6DSV is doing the job without magnetometer?

In the schematic for STM32N6 Vddcore power rail (attached), voltages of 0.81V and 0.89V are output from the SMPS using resistor dividers. I understand how the output of 0.81V was achieved using the 56K and 160K resistors and formula from the SMPS datasheet, but I'm not clear how the 0.89V output was achieved when the third resistor of 422K was added in parallel when the n-channel mosfet is used. Can someone please share the formula/how this was calculated?

Hi, I am working on OEMiROT bootloader for STM32H523. I have copied big parts of the ST OEMiROT example project from H533 example as this is the closest MCU to H523 from the flash memory layout perspectives. However, it is taking ridiculously too long time to refactor the security parts of the project as the H533 does have more hardware security peripherals than H523. I have cloned the STM MCUBoot and the ST Mbedtls repos in my project. I would love to know if there is an OEMiROT project example(s) for H523 and if you have any recommendation on how to process this faster as it has been taking forever to refactor and recompile the H533 example on H523 MCU. Cheers,Hani

On the wiki page:https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor It says:""This article applies to the 5.Y.* versions series of the X-CUBE-MCSDK. ACIM motors are not supported in older versions of the X-CUBE-MCSDK (v5.4.* and before). They are not supported yet in X-CUBE-MCSDK versions 6.*." However, the latest v5 version I can download is 5.4.8. So, it appears that I would need to use version 6 to compile the examples, while full support comes later?       

I'm currently at schematic stage designing a board based around the STM32U5G9ZJT6Q. The PCB will be produced and assembled by JLCPCB, so I had a look for a HSE crystal they have in stock and found this:https://jlcpcb.com/partdetail/YangxingTech-X322516MLB4SI/C13738https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8579709258350247936Calculations seem to check out OK (Gm_crit < Gm_critMax), I'm just a bit unsure about the Rext resistor and whether it is required for this part. I have put an 0603 0R resistor in for now, is there a way to calculate whether I will need some resistance there, or does it require measurements to be taken on the circuit, then adjust accordingly?Many Thanks,Anthony
