Hello,I want to develop a LoRaWAN sensor with STM32WL5MOCHxS, but I can't activate the LSE and HSE clock in CubeMX.Is there a way to make the adjustments in the .ioc?The configuration is possible in STM32WL5MOCH (expired).

Hi everyone,I’m having an issue connecting my STM32N6570-DK board to STM32Cube.AI Studio.The board is detected correctly by my computer, and I can see the COM port in Windows Device Manager. However, when I open STM32Cube.AI Studio and go to Board Settings, the COM port list is empty, so I cannot select the board.Here is what I have already checked:The board is connected via USB and recognized by Windows.The COM port appears normally in Device Manager.I set the board to DEV mode with Switch 1 = HIGH.I restarted STM32Cube.AI Studio and reconnected the board.Despite this, the COM port does not appear in the Board Settings dropdown in STM32Cube.AI Studio.Has anyone encountered this issue before with the STM32N6570-DK or similar boards?Is there any additional configuration or driver required for STM32Cube.AI Studio to detect the COM port?Any help would be greatly appreciated. Thanks!Best regards.

There is a problem with saving assembler source files when the C/C++ > Editor > Save Action > Format source code option is enabled:As a result, the file is not saved, and when it is just created, there is no file at all. It's quite irritating, especially because this is quite an old bug and no one has resolved it yet.

I can't get the STLink drivers installed on Windows 10 / 11 aarch64 Parallels VM running on Mac M1.Is there any support for ARM64 Windows STLink drivers?

Hi guys, Recently I have started to do some practical test with STM8S105. While trying to implement  PWM of TIM1 CH1 and CH2 with their complementary channels, it is seen that PWM pulses are generated only on main channels. Complementary channels are silent. Please see the code and suggest the way out.   #include "stm8s.h" void setup_clock(void) { CLK->ICKR |= CLK_ICKR_HSIEN; // Enable HSI while (!(CLK->ICKR & CLK_ICKR_HSIRDY)); CLK->CKDIVR = 0x00; CLK->SWR = 0xE1; } void setup_gpio(void) { GPIOC->DDR |= (GPIO_PIN_1 | GPIO_PIN_2); GPIOC->CR1 |= (GPIO_PIN_1 | GPIO_PIN_2); GPIOC->CR2 |= (GPIO_PIN_1 | GPIO_PIN_2); GPIOB->DDR |= (GPIO_PIN_0 | GPIO_PIN_1); GPIOB->CR1 |= (GPIO_PIN_0 | GPIO_PIN_1); GPIOB->CR2 |= (GPIO_PIN_0 | GPIO_PIN_1); } void setup_tim1_complementary_pwm(void) { TIM1->CR1 &= ~TIM1_CR1_CEN; CLK_PeripheralClockConfig(CLK_PERIPHERAL_TIMER1, ENABLE); TIM1->PSCRH = 0x00; TIM1->PSCRL = 0x00;

Hello,I would like to confirm how VBUS behaves in STM32 USB OTG depending on the Host/Device mode.Specifically, I would like to ask the following:When STM32 is configured as Host mode, should the STM32 source 5 V onto VBUS?When STM32 is configured as Device mode, does it only sense/monitor VBUS as an input?Is this behavior handled automatically by the internal OTG controller, or does it require an external VBUS power switch or additional external circuitry?Additionally, I would like to ask about a hardware configuration where an external 5 V supply is always present on VBUS, regardless of the STM32 Host/Device configuration.In this case, I would like to confirm:Whether this could cause any issues when STM32 operates in Host modeWhether it could affect Host/Device role detection or OTG behaviorWhether USB enumeration and normal data communication would still function correctlyIn other words, I would like to know whether a design where VBUS is always supplied by an external 5 V source is

I have been attempting to get a GPS lock with the TESEO-LIV3F, and I am not able to.  I am fairly certain that it has to do with how I designed the signal chain from the chip antenna to the RF-IN pin on the LIV3.  I have ensured that it was outside with a clear view of the sky, I have sent the $PSTMCOLD, 6 command to it.  I have tried to initiate with this command; $PSTMINITGPS,3912.826,N,11939.993,W,1487,17,02,2026,21,11,30, but then later sent $PSTMRESTOREPAR to reset it.  I do not have teseo-studio seeing as I am on linux.  Any help will be appreciated.

Dear STMicroelectronics Community, I am an electronics engineer seeking for technical help. My problem is that I want to reverse engineer an old STi7101 CPU based Set Top Box with HDMI output or say it less complicated, a Dish Antenna Receiver Box. My problem is that I need an Board Support Package for STi7101 board. I already had look for the datasheet of STi7101, and there is written that the CPU supports Windows CE. My plan is to run Windows CE on the box. Is there a way to make it work? Thank you.    

Hey I am having trouble tryng to connect my stm32g473 to a canbus. I am using a l9616 as a transceiver and the bus is functions as I have connected to it with an stm32f722re with the same l9616.The clock is 64Mhz,Ive used the canbit time calculation website to define the values of nominal time 1 and 2 to achive 500kbs.Also using NVIC and it seems to be configured fine. When tested in loopback the interrupt is called and the messages are received.This is the init with the filter config,as I ve understand I am not filtering anything and any of the messages on the bus should get to my uC.When running the state of hfdcan1 is Busy and also no error code show up.FDCAN_HandleTypeDef hfdcan1; /* FDCAN1 init function */ void MX_FDCAN1_Init(void) { /* USER CODE BEGIN FDCAN1_Init 0 */ /* USER CODE END FDCAN1_Init 0 */ /* USER CODE BEGIN FDCAN1_Init 1 */ /* USER CODE END FDCAN1_Init 1 */ hfdcan1.Instance = FDCAN1; hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV1; hfdcan1.Init.FrameFormat =

Hello Community,I am migrating a prototype CMake application to TrustZone for a test board targeting the STM32U575VGT6 MCU.  Launching a debug session for my project generates the following errors.  `I've attached verbose console error output in the attached file (console_error_output.txt).CubeProgrammer confirms I have the set Option Byte for TZEN .The debug configuration should be flashing the secure image before the non-secure.GTZC_NS/S are enabled. I have been following the tutorial Develop TrustZone enabled applications on STM32L5 ARM MCUs with STM32CubeIDE - Webinar Replay .  The instructions at 20:00 are completely arcane and I realize I am out of my depth of expertise to get this small project to work (.ioc attached).Does anyone have an application note or tutorial, pertinent to the U5 series, that explains how to flash and launch debugger sessions for a pure CMake + TZ project using only STM32CubeIDE 2.1.0, CubeMX 6.17.0, and CubeProgrammer 2.22.0

Dear all and ST Tech Support,I am writing to report a concerning inconsistency I encountered while migrating an older project to the latest version of STM32CubeMX (v6.17.0).Background: I recently reopened a project originally created about two years ago with STM32CubeMX v6.8.1 for the STM32H742VGTx MCU. My goal was to review the Timer 4 settings to use them as a reference for a new design.The Issue: Upon inspecting the Clock Configuration tab, I noticed that the APB1 Timer Clock was displayed as 120 MHz. Based on my original project notes, this value should have been 240 MHz.When I calculated the Timer 4 period using the 120 MHz figure, the resulting timing was twice as slow as it should be. While checking the documentation, I confirmed that Timer 4 is connected to the APB1 bus. In the CubeMX interface:The D2PPRE1 divider was set to /2, resulting in an bus clock of 120 MHz (which is the limit).However, the Timer Multiplier was stuck at x1, leading to an APB1 Timer Clock of 120 MHz.Obse

Hello all,  I need user manual for ST10F269 controller. Can you please share link or document? Thank you in advance.

I have come across an issue which I believe is a bug in the implementation of the osThreadFlagsWait function. Scenario A thread is waiting on a flag (e.g. 0x2u) for a timeout above 0, before this timeout should occur, there are multiple other flags set on the thread (e.g. 0x1u) using osThreadFlagsSet, this results in the osThreadFlagsWait function returning with a value of osErrorTimeout sooner than the set timeout. Cause The xTaskNotifyWait function which is called by osThreadFlagsWait returns each time the 0x1u flag is set, resulting in this section of code being run: Note that t0 is set to the return value of xTaskGetTickCount() at the start of the wait loop, so is the start time, tout is a timeout value passed to xTaskNotifyWait, which is originally the set timeout, but is adjusted each time the xTaskNotifyWait function returns. The issue with the code above is that the value of td is the total time that the thread has been waiting, this is subtracting fro

In the document UM3234 we see the following description of clock configurationOn my Nucleo board, I haven't blown any fuses and measured a clock frequency of 32 MHz. Since the XSPI is configured to have a prescaler of 2 by BOOTROM (also mentioned in UM3234), this implies that the board is using the default clock scenario. The document also mentions this regarding the nominal scenario."During secure boot, the boot ROM sets up PLL1 to switch to CM55, APB, AHB, and AXI clocking at the nominalboot frequency"Does this mean that if i dont have secure boot enabled yet, ill get the default clock, and as soon as I enable secure boot my clock frequency will increase to 400 MHz?. 

I've got a problem with MCU Selection not showing any options.Tried Reinstalling whole program also reinstalling Cosmic, I've got a working license for Cosmic also. Also with my professor we tried copying all files from his computer where it is working without problems (we are working both on windows 11). After that we used Revo Uninstaller to try and download both ST Developer Studio and Cosmic again but that didn't fix anything.We've run out of ideas why it isn't working. Even after connecting STM8S208RB and trying while it is connected didn't do anything.

Greetings! So I have a personal project, using a STM32U585 MCU, with a self-designed board, in which I have a bootloader and the main firmware. So basically I implemented a protocol for communicating with the board, I have a C program that sends a command and the board sends data (around 20Kb), using USB.The scenario is the following: I flash the firmware with the bootloader, after flashing, the bootloader jumps into the main program and starts running, I send a command (via host) to get data and the board sends me data and everything is running smoothly. The problem starts when I unplug the board and plug it again, when I send the command to get data, the board starts to send it and then it completely freezes. Another curiosity, this situation only happens when I plug the board in a USB hub... if I plug the board directly to the laptop, I won't have any problem. Any clue of what can be the problem? Power related? Is there any issue with the jump to the main pr

On STM32Hxx and STM32N6 families I have faced a situation where I need to modify startup assembly code  (startup_stm32xxx.s) to copy code (.text) into ITCM or clear RAM/TCM areas, for clean data or to prevent ECC error (on STM32N6). But next time CubeMX generates code, those changes are overwritten. Same story with SystemInit function in system_stm32xxx.c. So either manual restoration or script must be done. But it's getting quite annoying after several projects. I believe the purpose of CubeMX is to ease development, so I make a feature request:Please add user code begin/end comment sections that exist in main.c also into startup_stm32xxx.s assembly and system_stm32xxx.c source files.For startup assembly I wish the user sections are:User symbols definitions.User data copy.User zero fill.For system file I wish the user sections are quite similar to main.c:User includes.User defines/constants/variables.In SystemInit() function:In the beginning.After VTOR settingAt the end.User func

I just started looking at the STM32C071 family as an alternative to the STM32F042 and STM32F072 we currently use. To my disappointment the USB stack for the C071 is a total mess (dozens of files and complete spaghetti) and on top of that it seems to be written by Microsoft. So there is absolutely no way we are going to use that.Did I miss some other option for the USB device library? This USBX stuff definitely is no option at all.At first glance it looks like there are no significant differences between the USB hardware of the C0 and F0 if only used as device not host. So I am wondering if I can simply use the F0 libraries (which we have debugged and optimized…) on the C0. Or are there any hidden traps?
