the revision history shows they are now hidden from the user guide which seems a little pointless.the nucleo 32 user guide has them

I cant debug because I have some errors NO TARGET CONNECTİON AND DLL

Hi,​We are working on STM32MP151, with custom linux, no PMIC.​We have a reset button connect to NRST line, it works fine in Uboot or during linux boots. But right after the login prompt occurs, the reset button is nolonger work. When we hit the button, system seems crashed, no response from command prompt. We have to disconnect power and reconnect again.​Does anyone have experience with it?many thanks.​​

When I build the D:\Desktop\stm32Cube\en.x-cube-aws-v1-4-2\STM32CubeExpansion_Cloud_AWS_V1.4.2\Projects\B-L475E-IOT01A , it show me the error:d:\app\stm32cube\stm32cubeide_1.12.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.200.202301161003\tools\arm-none-eabi\bin\ld.exe: cannot use executable file '../../../../../BootLoader_OSC/2_Images_SBSFU/SW4STM32/B-L475E-IOT01_2_Images_SBSFU/Debug\se_interface_app.o' as input to a link.Though I add the .o into to PATH, it still error.

Hi, I want to debug OP-TEE on STM32 MPU board.Using 'st_stm32mp157f_dk2_demo_defconfig' configuration of STM32MP1 Buildroot external tree(buildroot-external-st), We indirectly confirmed that OP-TEE is built and ran normally on the board with Buildroot.I would like to customize the code in optee-os using the APIs provided by OP-TEE. Before I do that, I'd like to try to print out whether the code works at a certain point in time and the results of the modified code using the OP-TEE API and track the function calls.I followed the OP-TEE official document, but the debug log is not captured. In addition, the document only guides you on how to track function calls.Then, while reading the [How to debug OP-TEE] page on the STM32MP1 Wiki(wiki/How_to_debug_OP-TEE), I realized that the debug log is printed on the OP-TEE console(Marked by the cursor in the attached picture). So what I'm curious about are two things.1) Where do the OP-TEE debug results go? (What is an OP-TEE console?)2) Is the

Hello,I made a special card design that includes LSM6DSO32. I want to use this sensor in motion classification project. I want to ask a question about a subject that is said by everyone but I do not know. Everyone has mentioned that it is necessary to perform a calibration process to get the correct data from an IMU. However, the LSM6DSO32 sensor's user manual states that it comes calibrated from the factory. Do I need to calibrate this sensor extra?If yes, how should I do this for accelometer and gyro?I read an article about the need to subtract the gyro values from the new gyro values by averaging at the stationary position, is this a correct way to calibrate?I do not know how to calibrate the accelometer. I need help on how to calibrate both gyro and accelometer values.Without doing any calibration, I set, the gyro is 1000 dps and accel is 8G and the sampling frequency of both to 104 Hz. The values I measured under these conditions are as in the picture. The IMU sensor's&n

The documentation for the I2C interfaces on the STM32H747_CM7 board says:<name>SADD0</name> <description>Slave address bit 0 (master mode) In 7-bit addressing mode (ADD10 = 0): This bit is dont care In 10-bit addressing mode (ADD10 = 1): This bit should be written with bit 0 of the slave address to be sent Note: Changing these bits when the START bit is set is not allowed.</description> <bitOffset>0</bitOffset>This documentation is also appears in RM0399 rev 3 page 2182. (I'd like, but it says new members can't link).The ProblemThe problem is that documentation suggests that for 7-bit addressing, bit 0 is "don't care", and that the 7-bit slave address should be written to bits 1:7. However, in my experience this does not work. To make the code work I need to write the 7-bit slave address to bits 0:6 (which seems more natural anyway, I mean, why skip the first bit?). Writing to bits 0:6 is also what the STM32CubeIDE does as is shown by its `I2C_CR2_SA

I have an analog circuit that is read by an ADC input. I would like to have a self-diagnostic function where I inject a known signal to the input of that circuit with the DAC for a self test, then disconnect the DAC from the pin and leave the pin in analog mode for normal operation. I would like the pin to be in a high impedance state so as not to affect the circuit during normal use. What would be the best way to do this?My thought is to switch from:sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_EXTERNAL;tosConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_INTERNAL;with a HAL_DAC_ConfigChannel call after my diagnostic completes.

The approach described on the official XCUBE-AI documentation is not working for my case.

Hi all, I was wondering if anyone here has worked with the ISM330DLC IMU and was able to get positional displacement from it? I am trying to do this for one of my projects, but have run into drift issue. Any help is most appreciated! Thanks!Thank you,Imran

Hi,I am using the LSM6DSOX and ISM330DHCX in FIFO mode at 52 Hz or 208 Hz. For 52 Hz the real frequency turns out to be about 48.57 Hz, and proportionally so for 208 Hz. I am confirming this through the number of samples collected between GPS fixes and when comparing a signal against another type of sensor. The observed frequency is stable at this rate.Could this be real or is there something wrong in my application? The FIFO is checked using an RTC and is never allowed to run full (the overflow, full, overflow_latched) bits are checked. I drain (pop) the number of samples available at the RTC interrupt, but do not reset it. Does operating the FIFO or draining it halt the FIFO or reduce the number of samples?I observe the same both with the LSM6DSOX and the ISM330DHCX.IMU configuration: github.com/gauteh/sfy/blob/main/sfy-buoy/src/waves/mod.rs#L231FIFO drain function: github.com/gauteh/sfy/blob/main/sfy-buoy/src/waves/mod.rs#L395Best regards, Gaute

Hi all, I am looking for a list of resources (peripherals, memory, etc) that are required by the STM32_WPAN stack implementation for the STM32WBA52. I previously used the STM32WB55 and e.g. AN5289 lists which peripherals are shared with the M0/BLE core. Where can I find such information ?   Note: some clues are given in the "BLE_SerialCom_Peripheral" example for the STM32WBA52, by looking at the implementation of the "platform specific" functions required by the STM32_WPAN libraries (LinkLayer_BLE_Full_lib.a and stm32wba_ble_stack_full.a are included in the example project).   Thanks in advance.   Best regards, Jeroen  

I use a STM32F7508-DK as a USB-Device only as MSC with an SDCard. The Board is self powered.STM says to use VBUS sensing on self powered Devices. But with VBUS sensing enabled, the USB connection isn't registered and the USB connection doesn't work at all.Without VBUS sensing, the USB-Device connects and gets in to configured State. Data from the SDCard can be seen on PC and copied etc.But after disconnecting the hUsbDeviceFS.dev_state shortly turns to suspended State but immediately turns back to Configured State.The USB Suspended State Register ((USB_OTG_DeviceTypeDef *) (USB_OTG_FS_PERIPH_BASE+USB_OTG_DEVICE_BASE))->DSTSdoes not get set to 1How do i ge the VBUS sensing working on the STM32F7508-DK?THX for helping!

I want to connect four SATEL-53L7CX ToF sensors to a Jetson Orin Nx with an AVerMedia D131 carrier board. The board has a 40-pin expansion header with two i2c buses.I have created a wiring diagram to connect every two sensors to each i2c bus. Each sensor shares SDA and SCL with another sensor connected to the same bus, AVDD and IOVDD are connected to the Jetson with 5V and 3.3V pins respectively, the other pins of the two sensors (LPn, PWR_EN, I2C_RST) are connected to different GPIOs. Steps:I connect one sensor, then change the i2c address using set_i2c_address() and get the measurements. But when I connect the second sensor to the same bus, the line immediately stops seeing any connected sensors, even though the two sensors already have different addresses — modified 0x38 and default 0x52). Please, could you share thoughts on how to connect four ToF sensors to two i2c buses on Jetson? Thanks in advance. I will be very grateful to you!

Hi ST community, First question for me here.... It is about an emulated eeprom issue   I try to save dta to an emulated eeprom. Parameter are : starting dress : 0x800D00 page size 0x800 number of variable to be saved 37 guard page number =2 cycle life =1   I do manage to save and read from eeprom however, after a while (let's say between 500 and 1000 saving operations, the eeprom comes into the loop below and don't mnage to get out...   Would somebody knows why ? I assume my parameters are wrong but I can't figure it out ...     Thanks ,   Tjhe loop that blocks ... pageadress takes the value 28 27 26 and then back to 28.   while ((pagestate == STATE_PAGE_ACTIVE) || (pagestate == STATE_PAGE_VALID) || (pagestate == STATE_PAGE_ERASING))  {   /* Set counter index to last element position in the page */   counter = PAGE_SIZE - EE_ELEMENT_SIZE;     /* Check each page address starting from end */   while (cou

I configured ADC1 in CubeMX for a NUCLEO-U575ZI-Q board. When testing my application HAL_ADC_Enable(); returned error, RDYFLAG was not set after the timeout.When comparing my configuration to an example I discovered that HAL_PWREx_EnableVddA(); is not called in SystemPower_Config();. The issue got resolved with enabling vdda. I wonder if this is a code generation bug or I made some mistakes during configuration.
