STM32 MCUs

Inside Cube config, i do not get the other internal connected pins on pin 14, only PA8... in older versions it was available. The chip is STM32U031F8... What do i do wrong.. i need to use the uart_tx function on pin 14... Thank you  Old version from Cubeide... New version from Inet : 6.16.1 

Here comes another query about the status of a HUB device for the USB Host library. I have been working with the driver from herehttps://github.com/moribr/STM32F4HUB/blob/master/Project/Middlewares/ST/STM32_USB_Host_Library/Class/HUB/usbh_hub.cand have the HUB functional but cannot seem to get the MSC initialized and working. Why does STM not support a hub in their HOST Library? There certainly have been enough inquiries.

I've already seen 2 posts on this issue:https://community.st.com/t5/stm32cubeide-mcus/please-login-to-download-a-software-package-go-to-myst-gt-login/td-p/582064 https://community.st.com/t5/stm32cubeide-mcus/please-login-to-download-a-software-package/td-p/625708 Before redirecting me to any of those, I'll mention I get the same error but the answers, including the accepted one, don't solve my issue.I went to STM's site and downloaded the latest version of STM32CubeIDE. It says workspace_1.17.0.When I create the project, the following error shows up when it fails to generate code:So I do exactly this:I enter my existing account info:And nothing happens. The first time I did that it seemed like stuff are moving at the bottom right part of the screen, but It finished and still nothing.After configuring the board, when I click "Device Configuration Tool Code Generation" it will momentarily bring up a window and close it immediately. Bottom line I can't generate code for my proje

I am using the B-G431B-ESC1 board, which connects to my laptop via a micro-USB to USB-A cable. After a failed connection attempt, the board is no longer detected by STM32CubeProgrammer. Additionally, a file named "File.txt" is created on the MCU after the failed attempt.The contents of the file are:"The interface firmware FAILED to reset/halt the target MCU."This file appears to be causing issues with the connection to STM32CubeProgrammer.Could anyone please help me resolve this issue? 

Hello. How to configure the FreeRTOS LwIP bundle correctly on the STM32F407VET6 and PHY Lan8720, I'm configuring it in the Cube IDE. There is a ping without FreeRTOS, but there is no ping with FreeRTOS. Thank you very much.

Hello ST, I am working with STM32WBA52 and I am no longer able to connect to the device using STM32CubeProgrammer. When trying to connect, I got the following error: The interface firmware FAILED to reset/halt the target MCU A fail.txt file is also generated. The connection fails even when trying: Connect under reset. Different SWD frequencies. PH3 (BOOT) pin forced high. The issue appeared after changing security-related option bytes (TZEN / RDP). The device seems to boot normally, but debug access is blocked. I suspect the MCU enters Secure state early and prevents the debugger from halting the core. Is this expected behaviour on STM32WBA when TZEN = 1 and RDP = 1 without Debug Authentication configured? Does STM32WBA block SWD access by default in Secure mode? Best Regards,Dhia

hi all! i'm handling Foc-pmsm project, i use communicate ETH with other board via ETH but it connect too slow and open lost connection, i don't what issue because this is the first time i handle with ETH. can you help me take a look and show my mistake

In this IOC, touchgfx can only be placed in the "boot" sub-project. It cannot be placed in the "app" sub-project.

Hello everyone,I am working on a custom board based on the STM32U575RGT6 (1MB Flash). I am encountering a hard fault (SecureFault) during the initialization of the Non-Secure application after integrating the SBSFU.Context:Hardware: Custom board with STM32U575RGT6.Initial Project: A working application using TrustZone active + FreeRTOS (generated via CubeMX). The Option Bytes were set to a default 50/50 split (Secure/Non-Secure).Goal: Implement a Secure Boot / Firmware Update mechanism.What I did:I used the ST example for B-U585I-IOT02A as a reference.I integrated SBSFU_Boot and SBSFU_Loader into my project folder.I adapted the linker scripts (.ld), postbuild.sh, and flash_layout.h to match the 1MB Flash size of the U575RGT6 (vs 2MB on the B-U585I).In my original application, I replaced the .ld files and startup_xx.s files with those provided in the SBSFU_Appli example.Configur

Hello. I have a custom board with original f103c8t6 (sampled from eStore). PWM for pin PB4 is not functional, but bit banging with gpio write works. If tim3 respective channel is configured as pwm output, the output is stuck at VCC.  I configured the board correctly in CubeMX, as every other pin works correctly (including pin PB5, same timer, different channel) and double checked it again and again. Unfortunately I can't attach a project that reproduces the bug at the moment as I moved forward by changing the operating mode of the board (it commands a MC33926PNB H bridge and instead of having the H bridges enabled and sending PWM over IN1 and IN2, i set them as high or low depending on the direction and pwm the enable input, which functions well), but in a few days I can reproduce it. I am curios about what can cause the strange behaviour. It's not a conflict between JTAG reset as I have SWD enabled and even disabled it for a test which led to the same results.Here

Hello,I used the SBSFU 2.6.2 and it's STM32L432KC 1_Image example.Everything was cool, so I modified the UserApp and removed the demonstration application menu (a potential way to select a new download, this could save me...) Then, I unfortunately found out, I can't erase the chip so I can't flash a new firmware ... and finally I realized, I left most (or all) of the security macros enabled...I'm trying over the STM32CubeProgrammer play with RDP, WRP PCROP. Biggest issue to me seems PCROPas MCU rejects changes. The RDP I could set to level 0 easily (AA) and WRP protection also seem fine.Is there any chance to unlock my STM32L432KC nucleo back ?Thank youC:\Users\Vladimir.Sustek>STM32_Programmer_CLI.exe -c port=swd -ob displ ------------------------------------------------------------------- STM32CubeProgrammer v2.20.0 ------------------------------------------------------------------- ST-LINK SN : 0673FF515152827187223922 ST-LINK FW : V2J46M31 Board : NUCLEO-L432KC Voltage : 3.24

Extension 3.7.0st-arm-clang 19.1.6+st.10Hello,I am using CubeIDE für VSCode.I write programs for the STM32F756ZGTx. I have set ST Arm Clang as the compiler in CubeMX. Redirecting the output (printf()) via the serial debug interface is possible without any problems. When I try to output float or double values with printf(), I get some weird results.printf() with integer float/double yields correct results for integer float/double wrongprintf() with float/double integer always leads to incorrect resultsI repeated the experiment for double variables. The same problem occurs here as well.#include "main.h" #include <stdio.h> extern UART_HandleTypeDef huart3; double floatVar = 1.1f; void mainThread(void) { printf("\r\n\nHello from Nucleo F756 - float Test\r\n" "-----------------------------------\r\n"); for(;;){ printf("Float value: %f - Integer %u\r\n", floatVar, (unsigned int) floatVar); printf("Integer %8u - Float value: %f\r\n", (unsigned int) floatVar, floatVar); H

Hello everyone, I am quite new to this and I am using the STM32G474RET6 with BOR level 4. I changed the BOR level to level 0 and the board did not work properly. After changing it back to level 4, everything worked fine again. Is there any relationship between CPU speed (it is 168Mhz in our case) and BOR level?  We are not sure how to properly select the BOR level.    Thank you.

Our product is battery powered and uses an STM32L072CZT6.I did not write any of the power management code and I am not sure exactly what modes are used.When cold started and left to go into power saving mode, the current drawn by the entire product averages 82uA.However, after changing BOOT0, resetting, flashing the app using STM32CubeProgrammer, changing BOOT0 back, resetting again and letting the unit run until power-saving mode engages it then has an average current draw of 200uA, a 150% increase. I also discovered that re-flashing is not required; simply running the bootloader for a few seconds is enough to cause the problem, so it's not due to any code downloaded by the programmer.There seems very little in the CPU which survives an external reset. The RCC registers look the same in each case, and the only difference in RTC registers is the change of time and next scheduled alarm.Our console serial port is on PA2/3, there was a BlueTooth module on PA11/12 but that has been re

Hello.. i am writing a FD-CAN handler "fdcan1". I dun understand why it appears both in the micro's RAM and Flash? Can anyone advise? see screenshot for the memory detail.  

Hello everyone! In our system we have a set of subsystem that uses F4/F7 MCUs and one - with STM32H743 MCU. We want to use system CAN bootloader for all of them. Everything seems ok, except STM32H743 device. From AN2606 we know that it starts in bootloader with such FDCAN config: 'Connection bit rate 250 kbit/s', 'Data bit rate 1000 kbit/s', 'FrameFormat = FDCAN_FRAME_FD_BRS'. So, it waits for FD frames. The question is: can we use default CAN (not FD) with 250 kbit/s bitrate to update every subsystem there? Will STM32H7 recieve default frames and work in default  CAN formats?

Framebuffer is RGB565,Can I make a dynamic bitmap of ARGB8888? I made one by cacheable container and display the dynamic bitmap by a texturemapper but the image came out is not correct,something did appear on screen,but size and color not right. but if I change bitmap type to rgb565,the image show correctly,but with black background and  no alpha ,not what I wanted. There is enough  cache,I confirm the dynamic bitmap is created successfully on both type.I tried to display the dynamic bitmap by a Image widget,but the result is the same.In this forum,I can see a solution,to register a LCD32bpp class and set it as Auxiliary LCD in the hal.But I didn't found any thread on this subject.How to use off screen rendering of a textarea in a... - STMicroelectronics CommunityCan I get any help from any @st_it guys?

I followed the steps in this demo workshop to upload a simple program to toggle LEDs to the Nucleo-N657X0 board. The project is in FSBL. I can run the code in debug mode and upload the signed program to the external flash on the Nucleo-N657X0 board with STM32CubeProgrammer. However, when I tried to run the code with the 'Run after programming' option, I got the warning that the core is locked up. Besides, the Option Byte tab and the Erase tab are gone when the ST-Link is connected (See figure below), so the commonly suggested fix of modifying Option Byte is not possible..  My board is NUN657X0Q$CR1 (MB1940). I'm using STM32CubeProgrammer v2.20.0. The CubeIDE is v1.19.0. The firmware is STM32Cube FW_N6 V1.2.0. The SigningTool is v2.20.0 as the programmer.  I wonder if there a register that I can check to see the state of the MCU? Is it something to do with the Secure Programming? Any suggestions and comments are greatly appreciated!  

Background: I am using the STM32H747I-DISCO board and the BSP SDMMC example from the ST Repository as my starting point.  I can provide my code if necessary but wanted to keep post as short as possible.  I have looked at AN4838, AN4839 and AN5200 ST Micro Documents.  They are detailed but not getting me to my answer fast enough.   My Goal:I am trying to understand the detailed reason(s) why I need to enable the D-Cache when using FatFS calls with the SDMMC peripheral on the STM32H747I-DISCO board to avoid a timeout and also why I-Cache does not necessarily need to be enabled.     My Understanding to this point: The CLIFF NOTES of what I think I understand (between the ST documentation, AI hallucinations and true answers): Enabling the D-Cache reduces AXI bus contention since the IDMA in the SDMMC peripheral needs AXI bus to move data from the FIFO to SRAM on a very tight timeline, mandated by the SDMMC peripheral.  When you enable the D-Cach

It appears that the STM32WLxx FW 1.4 package includes a LoRaWAN stack that implements AES in software. Is there a technical reason that the AES accelerator in the STM32WLxx is not used? I can imagine things like:AES hardware functionally uses more power, or increases latency waking from STOP2, than the Semtech implementation.AES hardware does not provide the functionality required by LoRaWAN (at first glance, this does not appear to be the case).It's just too organizationally difficult to fork the Semtech code to use the AES hardware, or there is some licensing wrinkle (I can't imagine such a thing).If there's no reason not to use the AES hardware, I'd like to explore doing so.

Hi everyone[PN]: STM32F303RE, X-Nucleo IHM17M1, Faulhaber 0620-006B[VERSION]: 6.4.1[TOOL]: MC Workbench setup[DETAILS]: Hi everyone. I'm currently trying to configure the aforementioned hardware for motor control. My question is in regard with sensored startup. In sensorless mode, the open loop motor startup is configured in the "sensorless startup parameters" window in "Speed sensing config" settings. However, when in sensored mode (hall effect), there is no option to do configure the startup behaviour of the motor. I have tried both 6Step and FOC, and in both modes the motor fails to startup, but operates normally once I give it a "nudge". At least for my application, it seems like an open-loop startup is still required. Is there any way to accommodate this, or do I have a misunderstanding of the implementation in some regard.

Hello, I'm starting a new project with the N657 device.  I can't get the debug SWO port to work. 1- I'm redirecting the putchar to the SWO port: int __io_putchar(int c) { ITM_SendChar(c); // HAL_UART_Transmit(&huart3, (uint8_t *)&ch, 1, 0xFFFF); return (c); } 2- The trace and debug clock is set to 8mhz 3- In the debugger setup, i enabled the port and set it to 8mhz 4- in the debugger, I enable trace 0, and enabled it.   Nothing ever seems to get sent to this window.  Note: I know the cable/usb dongle is good since it works with the h743.   Does anyone have any suggestions? thanks Matthew    

Hi,I have an STM32g473 with 120kb or RAM, running at 169,75MHz.I have some image data stored starting at 0x2000_0000 which comprise of a palette of 235 colors in 00rrggbb format (1 word per color), follower by 304 lines of 370 pixels (one byte each, which is used as an index in the palette to get RGB value.)The data are copied in RAM to avoid wait states when loading them from flash, which mean most is in SRAM1 but the last 85 lines are in SRAM2 and MCC SRAM. The code is in flash.The first line of data display correctly, but the last 85 lines get one extra cycle per pixel (most probably due to reading the data).I could not find anything in the RM0440 that explains where this one cycle penalty come from. The only peripheral I use in addition to SRAMs and Flash (for the code) are the DACs and one GPIO (the gpio is not accessed during the loop that sends the pixels and get the penalties)Can someone help understanding this?

Hello ST Community, I am working on STM32N6 with an IMX335 camera sensor, ThreadX + USBX, and trying to stream live camera video over USB Type-C (UVC) to an external screen / PC. Current status: - Camera + ISP + DCMIPP pipeline is working correctly - Live video is already displayed on the STM32N6 board screen - I want the same live video to be streamed via USB Video Camera / ISP configuration: - Sensor: IMX335 - Sensor output: RAW10 - ISP enabled and processing the RAW data - Frame size currently: 800 × 480 - Pixel size in memory: 2 bytes per pixel - DCMIPP is writing frames to memory using DMA My main confusion is: What is the exact output format from the ISP to memory?Is it RAW, RGB, or YUV (YUY2 / NV12), and how do we confirm this from the HAL / ISP configuration? USB UVC configuration I am using USBX Device Video (UVC) generated from CubeMX. CubeMX gives two main options for video streaming format: UNCOMPRESSED MJPEG UNCOMPRESSED: I understand this usually means YUY2 (YUV422) for U
