Seems like STLINK V3SET does not support CANFD, but STLINK-V3-BRIDGE API has CANFD functions in it. So which device supports CANFD? Is there newer version of STLINKV3SET that has CANFD in it?

I would like to enable WiFi on the STM32L4 Discovery kit IoT node (B-L475E-IOT01A) and run a very simple HTTP server inside a FreeRTOS task.I would prefer to use the STM32CubeIDE to do this but will yield to MBED or some other framework if necessary.Any pointers, please?Currently, I do not see a way to enable WiFi in STM32CubeIDE.I do NOT want to set up this as an IoT node to any cloud.Thanks!Joe

By setting up a new project in STM32CubeMX 6.10.0, when adding a Semaphore in FREERTOS, the generated code is not correct, and the binary semaphores are initialised in a Taken state ( initial_count=0 of osSemaphoreNew() )  - resulting in the fact that the application will never be able to take the semaphore - see code snippet below.    /** * @brief FreeRTOS initialization * None * @retval None */ void MX_FREERTOS_Init(void) { /* USER CODE BEGIN Init */ /* USER CODE END Init */ /* USER CODE BEGIN RTOS_MUTEX */ /* add mutexes, ... */ /* USER CODE END RTOS_MUTEX */ /* Create the semaphores(s) */ /* creation of i2sHalfCpltReadySem */ i2sHalfCpltReadySemHandle = osSemaphoreNew(1, 0, &i2sHalfCpltReadySem_attributes);    The correct function call should be with initial_count=1 as here below and how it was in older MX versions   foo = osSemaphoreNew(1,1, &bar);  For users having the same issu

Hello all,I have an application in which I want to control four BLDC motors independently using the FOC. I want to use a STM32G484 for this. The question now is how I can distribute the interrups so cleverly that I can control all motors with 16kHz without them blocking each other.Many thanks for your answers :)

Hello, may be someone can answer the following question:I would like to order from estore a NUCLEO-H755ZI-Q dev board but would like to clarify one moment. The description says: **** On-board ST-LINK (STLINK/V2-1, STLINK-V3E, or STLINK-V3EC) *** If I understand the situation correctly those types of debug./program. are mutually exclusive.  How do I order NUCLEO-H755ZI-Q dev board with STLINK-V3 and not V2? I opened a ticket with Sales/CS on March 6 (Case# 00227964) and so far received 4 replies ranging from "will send it to A, he knows better" to "the board is sold by a third-party distributor, so we dont know ask them" i.e. people have no idea what is being sold through ST web site.What is really upsetting is that on the web page in question https://estore.st.com/en/nucleo-h755zi-q-cpn.html the customers are encouraged to contact sales if they have any questions.   Thanks!

I'm following along AN6000 to bypass the internal SMPS of the STM32N6 and use my own SMPS and LDOs power several of the power rails for the MCU and have some questions:1. In section 3.2 "System power/up/uncontrolled power-down sequence", the document states that the bootloader software must disable the internal SMPS by clearing the SDEN bit in PWR_CR1 register. Is this behavior configurable via CubeMX setting, or needs to be set manually in bootloader and if so, is this achievable once Vdd comes on?2. In the same section, it states that the PWR_ON signal is activated and Vddcore, Vdda18x and Vddperiph are enabled. The PWR_ON signal is asserted automatically once the power thresholds are reached, correct, or do I have to set the signal manually?3. In section 2 "Discrete power supply topologies", the diagram shows the LDOs and SMPS for Vddcore, Vdd, Vdda1V8_AON, vdda1v8 and Vddperiph but I do not see an LDO or SMPS for Vddio although I see Vdda1v8 powering some IO blocks. My confusion is

Dear,I'm trying to use the ETH with Zephyr RTOS 3.5.99. It was built the samples/net/dhcpv4_client sample, however, I tried to build others examples from samples/net/socket, such as echo and echo_client, but was impossible.I would appreciate it if anyone could provide information on how to set up ETH on Zephyr.Thanks.

Hi,I am working on a product for one of my clients that included two MCUs (STM32h755) on the same board working together and he requested both MCUs to be run on the same time "same clock", to be synced together. could you please advise if it possible to add a clock generator IC to feed both MCUs same clock. if so, please suggest a component or a document that will help me with this design.Thanks

I need to save a couple of bytes (a settings struct) to upper (last) page of the Bank1 flash. The settings are changed very rarely so lifetime of the flash is not an issue. The settings struct has a CSC member so when the settings are read from the flash during startup the settings would be applied only if the CSC of the settings struct is right.I know that I have to unlock, then erase a full page (128kB) before saving the app settings. How can I do this using HAL_Flash_xxx calls? I also must lock out the last page of Bank1 from code space (Linker file?). Can anybody send an example? I am using STM32H7474I-DISCO discovery board. Thanks,LouisPS: Adding a small, external SPI/I2C NVRAM/Flash chip won't work. I have to solve saving/restoring settings within the discovery board. 

I am writing this post in case anybody encounters a similar problem. I had a problem with assigning IP address to STM32F769I-DISCO devboard and communicating with it via Ethernet while using LwIP and FreeRTOS. The solution to this problem was disabling D-Cache in Cortex_M7 settings in STM32CubeMX. I don't know if I would ever think about trying this out if not for the old forum thread I found.

Struggling to get my own STM32U5A5 board working... the USB HS PHY was not working, until... (see below).I was confused also with this thread:https://community.st.com/t5/stm32-mcus-products/stm32u5-and-usb-hs/td-p/571774This told me actually as well: you need an external XTAL, not a CMOS OSC (and maybe 16 MHz). - But not true.I have changed my SystemClock_Config() !Instead of an external 16 MHz XTAL (as on NUCLEO-U5A5ZJ-Q board) I have an external 8 MHz CMOS OSC (not a XTAL).The USB CDC (VCP UART) project, running on NUCLEO board - runs now also on my own PCB! Cool.Some other tweaks needed to reuse my NUCLEO-U5A5JZ-Q project (e.g. no UCPD1, no ADC VBUS sensing), but this SystemClock_Confing() did the job:RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE;#ifdef NUCLEO_BOARDRCC_OscInitStruct.HSEState = RCC_HSE_ON;#elseRCC_OscInitStruct.HSEState = RCC_HSE_BYPASS;#endifRCC_OscInitStruct.HSIState = RCC_HSI_ON;RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALI

Hi All, I was searching for a I/O bank voltages of different GPIO ports available in the controller. In datasheet there is no proper information on supply voltages for the GPIO Pins., could you please suggest the document which is having the information of supply voltages for different I/O banks.   Note: However, I am unable to confirm which ports support 3.3V. Table 18 of the datasheet does not correlate the PIN numbers with VCCIOX. Below figure shows only few I/O ports.     Regards Tejas

I was just debugging earlier today on my STM32H7B3I-EVAL board from my Mac (Sequoia 15.3.1), which I have been doing for weeks.  Note, the eval board has a built in ST-link.  Things were going great.  I figured it was a good time to install github integration.After I installed eGit from the Eclipse Marketplace, I saw the indication that I can update from 1.17 to 1.18 and clicked on it.  Everything appears to go smooth on both the git stuff and the upgrate of the IDE.  Unfortunately 1 problem was found after installation.Projects in the workspace that were working minutes before the upgrade, and have NOT been modified after the upgrade, have all now consistently failed to debug.  The message is the same, that no ST-link was detected.My suspicion was that this was a problem with the STM32CubeIDE.  I tried out the STM32CubeProgrammer and it works wonderfully still.  I assume that is enough to show that the ST link is fully operational.I went ba

Hi guys. I am using STM32G431KBT MCU. I am using 2 MCU (master / slave) and they communicate via canbus. Canbus is working good but canbus filter is not working. Master canbus address is 0x200 ans slave address is 0x101. I changing master ID (0x150) but the slave still continues to receive data and go to the canbus callback program. Cubemx settings are as follows; And program is here;   /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); MX_FDCAN1_Init(); MX_TIM2_Init(); /* USER CODE BEGIN 2 */ Configure_FDCAN_Filter(); if (HAL_FDCAN_Start(&hfdcan1) != HAL_OK) { Error_Handler(); } if (HAL_FDCAN_ActivateNotification(&hfdcan1, FDCAN_IT_RX_FIFO0_NEW_MESSAGE, 0) != HAL_OK) { Error_Handler(); } Config_CANTX();void Configure_FDCAN_Filter(void) { FDCAN_FilterTypeDef sFilterConfig; sFilterConfig.IdType = FDCAN_STANDARD_ID; // Standart 11-bit ID sFilterConfig.FilterIndex = 0; sFilterConfig.FilterType = FD

Hi,In CubeIDE, new project, choosing STM32H755ZIT6 (the NUCLEO-H755ZI-Q), the board stops responding when turning off and on the power to the board. I have made a simple LED example with everything set to default with the addition of two user LEDs blinking - one controlled by M7 and one by M4 core. It works fine until you remove the USB and put it back in. Then ST-link cannot connect. I have used the debug configuration from the application note:Getting started with projects based on dual-core STM32H7 microcontrollers in STM32CubeIDE - Application note STM32Cube Version: 1.17.0CubeMX version: 6.13Firmware package: H7 V1.12.1 Best regards Nikolaj

Hello!I have a question regarding the system clock source selection. Specifically, I would like to understand how the High-Speed External (HSE) clock works. Does the board already include a crystal or ceramic resonator that serves as the source for the HSE, or is it necessary to connect an external one?If the HSE is configurable in STM32CubeIDE as a clock source, why is that possible? I’m wondering how the system works in that context.Thank you!
