HIAt what temperature the TS_CAL2 value for the STM32G431 is detected?In the datasheet it is reported 130 degrees while in the library "stm32g4xx_ll_adc.h" TEMPSENSOR_CAL2_TEMP is 110 degrees Thanks

Hello Guys,I tried defining STIROT_ILOADER_DEBUG in the main.h of the iLoader and then i built it and uploaded the Code via script after getting loaded only STiROT Application Logs are are printing but STiROT_iLoader logs are not printing, how can i resolve this issue? 

Dear ST Forum members,I am developing the Prototype with STM32WL microcontroller to which I provide a schematic snippet below:+ SWD 1x5 goldpin connector:If the image quality doesn't let you inspect the nets, I will provide a better image later.Th

Hi, I followed the instructions in this post to install the STM32Cube extension for Visual Studio Code. After completing the installation, I noticed that two icons appeared in the left panel: one labeled "STM32Cube" and the other "STM32 VS Code Extension".The difference is that under "STM32Cube", there is only a "Key Actions" menu instead of the Project

I am using the NUCLEO-L433RC-P with the blue top switch (pin PC13) configured as a wake pin.When the switch is pressed, the MCU should wake, then turn the LED on, then shutdown.But for some reason the MCU wakes twice as observed by the following behaviour: Switch pressedMCU wakes (LED turns on)MCU shuts down (LED turns off)MCU wakes again (LED turns on)LED finally shuts down (LED turns off)This happens even though the switch is only pressed once. The switch has RC filters so its not a debounce issue, especially as it happens even if the switch is held down.  

I have set PA3 pin as input with pull up mode. But testing this pin by multimeter I get high impendance state (0.5V) on it. Must be 3.3V (logical 1). I use stm32F417ZGT6. 

Issue 1：file: hall_speed_pos_fdbk_sixstep.cfunction: HALL_TIMx_CC_IRQHandler()line: 393The prescaler is affected when UEV is generated by the function SixStep_StepCommutation().This function is called immediately after the prescaler is set,so the prescaler value is applied in the current loop, not in the next loop.Therefore, the prescaler does not need to be incremented by +2;incrementing by +1 is enough.Issue 2：file: stm32g0xx_mc_it.cfunction: TIM2_IRQHandler()line: 148When the prescaler is changed, it is affected by the update event, which is generated in software during commutation.If a phase shift is set, the update event is generated with a delay.As a result, the counter may run with two different prescaler values.

Hi, I want to make a simple application with an STM32WB5MMG that exposes a characteristic which I can read. I created the service and the characteristic, and I enabled the CHAR_PROP_READ property. In custom_app.c, I then use Custom_STM_App_Update_Char to update the value under the CUSTOM_STM_FW_VER_READ_EVT case branch. However, I can't read the correct value—it always returns 0.I also tried enabling the GATT_NOTIFY_READ_REQ_AND_WAIT_FOR_APPL_RESP property, but from the debugger, I see that it doesn't even enter the void Custom_STM_App_Notification(Custom_STM_App_Notification_evt_t *pNotification) function.Can someone help me?Thanks.

Hello,I am working with the STM32N6570-DK board and using STM32CubeIDE (version 1.19.0) .I cloned the full STM32N6 repository from:  https://github.com/STMicroelectronics/STM32CubeN6 When I try to build and flash the Ux_Device_Video project, I face a problem: I right-click on the Ux_Device_Video→ Debug As → it flashes successfully, but the program never reaches  main(). (Normally in every program the debugger points to first line in main).When I press Run, the debugger only executes a few assembly lines like below and stays there:

I'm using ST MC Workbench v6.4.1  to generate sensorless FOC control code and trying to run a motor with the following setup:PWM frequency: 50 kHzMotor: 7-pole pair BLDC, 1750 KvBus voltage: 24 VMost other parameters are at default valuesWhen I run the motor unloaded and increase the speed, the SPEED_MEAS parameter (observed in ST Motor Pilot) suddenly turns negative around 27,000 RPM. I’ve tried adjusting current loop and PLL parameters, but it didn’t help.Any idea what could be causing this issue? How can I resolve it?

Hi everyone,I’m trying to deploy a wav2vec model using STM32Cube.AI and ran into an issue during onnx conversion.NOT IMPLEMENTED: Unsupported layer types: LayerNormalizationI’ve read the documentation at supported onnx operators and it seems that LayerNormalization is not currently supported.I have a couple of questions:Are there plans to support LayerNormalization in future releases?If not, does anyone know a recommended workaround other than just modifying the model to use another type of normalization? 

Morning all,I'm really having some issues getting the latest CubeIDE (1.18.1) to work.This problem started when I was trying out some different processors for a new product (a CPU upgrade) - everytime I selected the new CPU and attempted to start a new project, I was told that it was missing an XML file and that no new project could be started without it.After trying/retrying several times with searches for the XML file turning up nothing - I came to the conclusion that I needed a re-install of the tools as this would give me the XML file I needed for the new board.I downloaded and installed the latest 1.18.1. Everytime I started CubeIDE, I would get a popup window after the splash screen  saying this or that log would hold the details of what was going wrong. Reading the log file showed that there was no swt-win32 in the java library path. The path listed in the log is pointing to a .DLL, which exists at the location given.Assuming I had an o

Dear All,I'm having problem to get DFU over USB running on custom board.In general device can boot from SD card and with no SD card it can be detected via uart4 by STM programmer, so it enters DFU as far as I can tell.USB DP/DM is connected to DP2 (being pulled-up to ~3.3V) and DM2 (looks like a weak pull down). OTG_ID (PA10) hangs free and OTG_VBUS (U15) hangs free.3V3_USBHF+FS connected to LDO4 and present (3.3V)EDIT: 24Mhz xtal present, no 22Ohm series resistors and also removed all esd protection at this moment...Nothing happens on the USB lines when I connect the cable to the PC and the device is not detected. The voltage on the OTG_ID pin is LOW - which is strange, as is should be pulled up theoretically. Connecting OTG_VBUS (PA10) pin to VBUS from the connector does not change anything, that is - no detection, no communication, looks like my device behaves like a host.I could not find any reference design for USB connection, bu

Hi,I have got a TFlite model with s16 activations and s8 weights.1. Without NPU. I run this commandstedgeai.exe generate --target stm32n6 --name network -m %1 --compression none --verbosity 1 -O time --output ./X-CUBE-AIand the utility produces a network with "float" activations and weights (and adding int -> float at the start, and float -> int at the end).Can I use some command line options to force the utility to generate "integer" layers?2.

Dear，Could you kindly help provide MTTF/FIT for LMV321ILT

On the STM32WL33 chip, is it possible to switch between LPAWUR Wake-up Radio Rx mode and PWR DeepStop RTC mode in the same code?

STM32CubeIDE 1.9.0 has been working fine, until tonite. I started it and after it asked which workspace it acted like it was loading but never went anywhere. I killed it, removed the .lock file and restarted and the same thing except it's now exiting.

Even tried with many different resistance value (Rled=100,R=330)

Hi,I'm using IIS3DWB MEMS sensor to get the motor vibration data which will have a bandwidth of 6kHz and need to store it to a 16GB SD cardI'm confused to calculate the data rate, i mean what is the ODR i need to consider?My calculation is :ODR = 26667 and 3 axis 6 bytes, which becomes 160kb/s and 12.89GB/day precisely, which is a lot of data for a dayShould i consider the ODR to be 2x times the bandwidth (6kHz in this case)?Also let me know about the raw data and how can i filter out the 6khz frequency data that i need

Hi,Running STM32MX Tool 6.15.0 On Windows 10.Started a project for a STM32U535CCTx.I've enabled ADC and configured channel IN8. The software thinks this is connected to PA4, but the datasheet says it is connected to PA3. See screen caps below. Regards John  

Good evening,I’m reaching out to ask if anyone might be familiar with a solution to a hard fault issue we’re currently encountering.Here is the situation:We are using a custom-designed board that incorporates an STM32H7 microcontroller and external Flash memory from Winbond. All source code is stored in the external Flash. The code itself is relatively simple and primarily handles UART communication.While debugging with CubeIDE, we frequently encounter hard faults when using the Live Expression feature. The fault appears to be an alignment error.The debugger connection is via SWD using ST-Link. Interestingly, when debugging via JTAG using SEGGER’s J-Link, the hard fault does not occur—even when using Live Expression. However, in this case, the console displays a message saying “cannot read register map.”This leads me to believe that the occurrence of hard faults may be influenced by the debugging interface (SWD vs. JTAG).I would great

I'm working on a custom board using an STM32H743IIT6. In general, the board is working, but I'm running into an issue with the RTC. The RTC is running accurately, but when I reset the board, the RTC resets. This happens even if I just terminate and restart the connected debugger, without disconnecting power. I've read through about 20 pages of RTC related posts here, and have checked all sorts of things:- I commented out the Cube/HAL code that initializes the RTC to a specific value- I checked the battery (1.6V with a 357 battery)- I tried using a method described on this forum: After initializing the RTC, store a magic number to a backup register. If that magic number is found in the backup register on startup, don't initialize the RTC again. It didn't help. I took this code out, because the RTC itself has a flag that indicates whether it's been initialized or not, and the HAL code skips initialization if the RTC is already initialized, based on that flag.-

I was reviewing the schematic for the STM32H7x3I-EVAL board and noticed that the ETH_nINT pin from the Ethernet PHY is connected to pin PG7 of the microcontroller.I'm having trouble finding clear documentation on how this pin functions. Could someone please clarify the following?What is the exact purpose of the ETH_nINT pin on this board?Does it require any special configuration within the LwIP stack to be used?Are there any example projects that demonstrate how to handle this interrupt? Any help would be greatly appreci

Hello Experts,Based on STM32MP257F-EV1 we have designed a custom board. For the DDR, PMIC, and eMMC we tried to follow the EV1 rooting as much as possible. There are few differences on the BOM though: Our DDR chips are Alliance Memory AS4C1G16D4A-62BCNOur eMMC is a Kingston EMMC32G-TS0A-01002We have build an image that can be flashed into the EV1's eMMC without any issues. Things go differently when we try to flash our 2 prototypes.  The first prototype stops after having properly downloaded the partition 0x3 fip-stm32mp257f:12:15:04 : Number of partitions: 14 12:15:29 : USB speed : High Speed (480MBit/s) 12:15:29 : Manuf.
