I am connecting IPMM15B’s J2 to IHM09M2's J7. There are  documents showing how J7 is aligned and where it is situated on the board. But I have no idea how J2 is oriented. The schematic is too brief. It could be opposite aligned if I turned the board around to the inverse side. I don’t know how the pins should be connected. I need to know where pin1 pin2 is situated on the board.  

Hi, I am using the STM32N6 nucleo board to print some application data using the ITM stimulus port 0 over the SWO pin. I am using the dev boot mode.My stlink version is V3J17M11, which is up to date, and my cube programmer version is 2.23.0, which is up to date. Problem statement: My program works in the Cube IDE, and it shows the output in the Serial Wire Viewer tab.Problem 1: When I try to use it with the Cube Programmer, I click the start button, and it says, Serial wire viewer configuration failed. ( elaborated below)Problem 2: When I try to use the J-Link with SWD in the Segger Serial Wire Viewer, the J-Link viewer configuration window just resets my MCU, and the code vanishes.I’ll share my main.c file below.ExplanationProblem 1:I tried a lot of things and read about the Access ports. My system clock is 32MHz, and the TPIU clock is 4MHz. The cube programmer’s SWV asks for the system clock, which I assume is the core clock, so 32MHz, but I have also tried 4, 8, 16, and 64 options.

I am attempting to use X-Nucleo-DRP1M1 + Nucleo-G071RB boards as data communication dock for with following behavior :- The dock is a sink by default and UFP, so that a non PD capable mobile device can connect and communicate with a USB peripheral using the USB OTG feature (even though the mobile device isnt being charged)- if a PD capable mobile device is connected, the dock can send a role swap requests so the mobile device is charged and connected to a usb peripheral. The charging voltage is 5V. It would be preferable if this behavior occurred reliably even in the case of a power cycling while remaining connected, and after repeated disconnects + reconnects. I attempted to use a CubeMX project following this guide (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Getting_started_with_USB-Power_Delivery_Dual_Role), setting the dock’s USB-C port as default Sink and enabled USB some connectivity features to enable connection to a peripheral. I do not think the behavior i seek should r

Hello ST Community,I would like to report a potential discrepancy I have discovered between the pin definitions in STM32CubeMX and the official datasheet for the STM32N6 series, specifically concerning the Serial Wire Output (SWO) signal used for debugging (SWV/ITM). This issue led to a hardware design error on my part, and I believe it warrants clarification to prevent others from encountering the same problem.According to the STM32N647xx datasheet (and related family documents), the SWO function is assigned to Pin PB5, The TRACECLK function is assigned to Pin PB3However, within STM32CubeMX (I am using version 6.16.1)(N6 MCU package version 1.3.0), the graphical pinout view shows that Pin PB3 is also listed with the "DEBUG-JTDO-SWO" functionality. More importantly, when configuring the debug port in the "SYS" settings (e.g., selecting "Trace Asynchronous Sw"), the software automatically assigns the SWO signal to PB3.Trusting the configuration tool, I proceeded to design my PCB wi

On STM32CubeMX 6.16, STM32N6 package 1.3.0, APB frequency limit is shown as 400MHz instead of 200MHz.AHB is correctly shown as 200MHz 

Gcc and Visual Studio correctly compile today's date __DATE__ to "May  6 2024". However STM32CubeIDE editor expands the macro incorrectly if I hover the cursor over it.Month name is in DutchMonth name is in lower caseDay of month is left-padded with 0 instead of a space 

Hi, I'm trying to access SD cards with an STM32C091 MCU. It seems like FatFS is not supported by default in CubeMX, therefore I looked into FileX. I don't have a need for running an RTOS, so I would like to run FileX in standalone mode. However, the FileX parameters in CubeMX don't contain FX_STANDALONE_ENABLE (see attached). Can anyone offer some insight into the topic?  Thanks you for your time and effort. :) 

Hi ST team,we are currently developing a new industrial product embedding the STM32U5A5ZJT6Q MCU.For our system reliability assessment, we would like to request the official reliability data for this specific component.Could you please provide:MTBF (Mean Time Between Failures) FIT rate (Failures In Time)If available, we would prefer values calculated according to:Telcordia SR-332 MIL-HDBK-217 Ground Benign (GB) operating environment assumptionsThank you for your support.Best regards

I am using Nucleo F103RB Kit which has onboard St-Link.I created a simple Led Blink project, and when trying to debug or program the board, I am getting the message that “No ST-Link Detected, and so on”.But as can be seen from the below screenshot the ST-Link is detected.But when I used the STM32CubeProgrammer, and programmed the same binary generated by STM32CubeIDE, it works fine, i.e. programming works fine, as can be seen below. I am also learning in parallel the Zephyr, and there also with command `west flash` st-link is able to program the binary but not with STM32CubeIDE, which is very strange.Apart from this I used the tool from segger to convert the st-link to jlink, and after converting this to jlink, and then selecting jlink in debug configuration of STM32CubeIDE, it works fine.Can someone please help me that why on-board st-link is not working with STM32CubeIDE?Summary:ST-Link not working with STM32CubeIDE using the latest version 2.1.1 ST-Link when converted to JLink works

Hello, I have been having a ton of trouble setting up a simple ADC + DMA on the new STM32N6 Nucleo board. I have confirmed that my adc is sampling by looking into the data register of my ADC. However, the only way I got the HPDMA to write in my adc buffer was through DTCM as I followed the reccomendation of this topic, in order to avoid the hassle with S and NS domains. However I wish to sample at 2.5 MSPS and through DWT and the Cplt_Callback of the HPDMA I found that my data actually came through at 1.44MSPS. The ADCs of this STM are rated for 5MSPS.Can anyone help me make it so that I can sample at the desired rate and actually get a hold on that data at the desired rate. Also if you know of a better fix than cranking the CID to 11 I’d happily take it. Thanks, Lorenzo

The top line is S4 then there is a QR Code and then 513. I think it to be one of the iNEMO Inertial Modules but I don’t know how to go about checking which one. I don’t know the dimension of the package  

In CubeMX Version 6.17.0, for STM32G474RET6, HRTIM1, TIMA output2 configuration, set sources is forced to 0 cannot be changed to 1 and it is showing "Set Sources: nothing to set as Dead Time is enabled, Output2 signal is defined based on Output1 Configuration Set Sources" even if Dead time is kept disabled. This issue was not present on previous versions of CubeMX.

I am a long-time STM32CubeMX user (7+ years). I ran into an issue with STM32CubeMX recently while modifying an existing configuration for an STM32L4 project. This is a usability issue.In the NVIC configuration page, there are two tabs, one labeled "NVIC", the other labelled "Code Generation". In the NVIC tab there is a column labelled "Enabled". The issue is with the word "Enabled" -- it has a clear meaning with regard to interrupts. I wanted the interrupt handler created, but I wanted the code generated with the interrupt disabled. I made the mistake of disabling "Enabled" in the NVIC tab, initially ignoring the "Code Generation" tab. The result was that the interrupt handlers, along with my user code, was removed from the stm32l4xx_it.c file. (I had it in source control, so nothing was lost.)"Enabled" on the NVIC tab means that the interrupt is used and a candidate for code generation. The selection I wanted is on the "Code Generation" tab labelled "Generate Enable in Init". The word

Hello,I just downloaded STMCubeIDE 2.1.1 to generate a simple project for a Nucleo-C562RE board.I am not using CubeMX2 (for various reason, that is not the point).The default empty project generated for STM32C562RE by the IDE has only 1 SRAM element with a size of 64K, instead of 2 SRAM elements of 64K each.FLASH size is correct though.Out of curiosity, if ST were to push a fix for this kind of bug, would it be a new IDE release ? or could it be a STM32C5 pack update only ?

Hello, I'm trying to create a project with custom model via STM32 Cube AI studio, which uses STedge Core AI v. 3.0.0. Validation is performed on STM32N6570-DK. I'm getting following error:E200(ValidationError): TARGET: Unable to bind the ST.AI runtime with "network" c-model: [] E801(HwIOError): Invalid firmware - COM7:115200 When running same command from command line I see that progress goes to 74,8 % and then stucks until error is displayed.See attached failed report for details. 

Hello,For one of my project, my goal is to use PTP to synchronise multiple STM32H563 to one host.However, when configuring the ETH Device, I can only enable RMII, as the "RMII_PTP_SYNCHRO" is greyed out.I've read the pop up that tells me to enable TIM2 as a slave with trigger source "ETR1 through Remap", Channel 1 as "Input Capture direct mode from Remap". And both "remap capabilities" are set to "is connected to ETH_PPS".Is there something that I'm missing ?Best regards

Hi everyone,the update to CubeMX 6.17 seems to introduce a new valid range of the "First RX Descriptor Address" of the Ethernet setup on a NucleoH755 board. This is also the case for the STM32H745.This is the valid range according to the CubeMX field description (there is also a typo for the Parameter Description "Fisrt"):First Rx Descriptor AddressFirst Rx Descriptor Address must be between 0x24000000 and 0x30047fff.Parameter Description:Fisrt Rx Descriptor address must be only in the D2 Domain AHB SRAM. Rx descriptor address must not exceed Max value and must no overlap with Tx descriptor and Rx buffer. These areas must not be cacheable.This contradicts the knowledge base article: How to create a project for STM32H7 with Ethernet and LwIP stack working The reference manual also states that 0x3004000 - 0x3004FFFF should be part of the D2 Domain AHB SRAM3 and hence be part of the intended area. Is this just a bug or do I overlook something?Kind regards

Hello, I was going through the schematic of STM32U5G9J-DK1 where I came across the unused LDO (U19) for generating 1.8 V on this board. I wanted to know the significance of this LDO and what were the reasons to keep it unpopulated?Also, can I expect to see an improvement in the driving capability of this rail in case I wish to populate U19 with TPS76301? If yes, which orderable part no. of the same would be recommended?

  Hi everyone,I think STM32CubeMX is generating an incorrect configuration for STM32L071.In CubeMX → System Core → SYS → System power supply,I selected Power Regulator = SMPS (instead of LDO) and generated the project.After code generation, I get build errors because CubeMX inserts code that does not exist for this device / HAL package:In stm32l0xx_hal_msp.c, I see references like: HAL_PWREx_ConfigSupply(...) PWR_SMPS_SUPPLY But for STM32L0 / my CubeL0 HAL, these are not definedMy version is :

When choosing SmartCard mode for USART, parameter Parity is automatically set to Even. However generated code in usart.c, does not has:hsmartcard1.Init.Parity = SMARTCARD_PARITY_EVEN;Only when I manually reselect that in GUI, the parity will be set in the generated code.I am using Nucleo-G0B1RE.

Hello,I have been trying to configure the ethernet RMII with PTP synchro on cube MX. The idea is to link the PPS signal to trigger the timer. I can't manage to get the remap to be done to the ETH_PTP_PPS as is not displayed in the dropdown. According to the same cube mx that option should appear. On a side note when I enable the RMII_PTP_syncro I also loose all the config information of ethernet which i find rather strange. Do any of you have any suggestions on what's the proper way of configuring this? Is this even possible or is just a bug of the prompt that implies is possible? Thanks in advance ;)

Hello,  Began learning STM32 MCUs with my Nucleo-H753ZI board and I think I found a bug. The IO configurator on CubeIDE thinks user LED2 is on PB7 and is blue coloured. I'll paste the code it generates below. But in fact, the user manual UM2407 says user LED2 is on PE1 and is yellow coloured, which is indeed correct. Generated code from CubeIDE for Nucleo-H753ZI:#define LED2_PIN GPIO_PIN_7 #define LED2_GPIO_PORT GPIOB Appears to be a bug that should be fixed in the BSP.
