STM32 MCUs

This thread is split from this old discussion @FBL  RCC_USBPHY1REFCLKSOURCE_OTGPHY1 and RCC_USBOTGHS1CLKSOURCE_HSE_DIV2 are missing in generated code I created a simple FSBL application that is jump to the AppliThe Appli is using the same approach (SW solution) like it was implemented inside "Ux_Device_CDC_ACM" example, (it was migrated in to the Appli)Currently, during debug, I am observing the same issue like it was described before (stuck in USB_CoreReset() during checking the "USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST" )The solution, that you provided, it looks like it does not working anymore by using the latest Cube_FW and generated compilation errors (no defines for the RCC_USBPHY1REFCLKSOURCE_OTGPHY1 and RCC_USBOTGHS1CLKSOURCE_HSE_DIV2).Could you please provide a solution (it would be better to see an example) how to solve this issue base on the latest MXCube and STM32CubeIDE versions. Currently it is : STM32CubeIDE_2.1.1  STM32Cube_FW_N6_V1.3.

Hello, I would like to learn if there is an easy way in STM32CubeMX2 to start a new project with an existing ioc2 file. It seems that the only way I can do this is make a copy of the ioc2 file, do a text find and replace for the name of the project and reopen the project in MX2.In essence, I like to start a project from a working ioc2 configuration and modify it to work on a fork of the project. I don't want to recreate a complex configuration from scratch because I found the hard way that it is easy to make mistakes or to omit something. Thank you,-Gil  

Hi,How do I serve request Get Source Capabilities Extended? I'm using STM32G0B1 with a port configured as SRC.When a SINK sends the Get Source Capabilities Extended the STM PD library responds with 'Not Supported' and my code is not aware that this even did happen. Is there way to intercept and serve this request? At least the callback structure does not appear to have direct support for this. USBPD_DPM_ExtendedMessageReceived is never called. /* CAD callback definition */ static const USBPD_PE_Callbacks dpmCallbacks = { USBPD_DPM_SetupNewPower, USBPD_DPM_HardReset, USBPD_DPM_EvaluatePowerRoleSwap, USBPD_DPM_Notification, USBPD_DPM_ExtendedMessageReceived, USBPD_DPM_GetDataInfo, USBPD_DPM_SetDataInfo, USBPD_DPM_EvaluateRequest, USBPD_DPM_SNK_EvaluateCapabilities, USBPD_DPM_PowerRoleSwap, USBPD_PE_TaskWakeUp, #if defined(_VCONN_SUPPORT) USBPD_DPM_EvaluateVconnSwap, USBPD_DPM_PE_VconnPwr, #else NULL, NULL, #endif /* _VCONN_SUPPORT */ USBPD_DPM_EnterErrorR

How can I do that with Version: 2.0.0?

Hello,On a STM32H7RS are using the USB_OTG_HS peripheral in PCD_SPEED_FULL mode using internal clock.After I was able to configure the clock so that the MCU is responding on enumeration requests. The responses however seem to be partially incorrect; the trace tool shows stalls.I did not found an example in current https://github.com/STMicroelectronics/STM32CubeH7RSThe following changes are applied to a CubeMX generated projectmain.c SystemClock_Config:LL3.PLLN was set to output 24 MHzRCC_OscInitStruct.PLL3.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL3.PLLSource = RCC_PLLSOURCE_HSI; RCC_OscInitStruct.PLL3.PLLM = 4; RCC_OscInitStruct.PLL3.PLLN = 60; RCC_OscInitStruct.PLL3.PLLP = 2; RCC_OscInitStruct.PLL3.PLLQ = 40; RCC_OscInitStruct.PLL3.PLLR = 16; RCC_OscInitStruct.PLL3.PLLS = 2; RCC_OscInitStruct.PLL3.PLLT = 2;Configure CRS __HAL_RCC_CRS_CLK_ENABLE(); RCC_CRSInitTypeDef RCC_CRSInitStruct = {0}; RCC_CRSInitStruct.Prescaler = RCC_CRS_SYNC_DIV1; // default RCC_CRSInitSt

Hello, I am currently using the NUCLEO-U545RE-Q and trying to set low-power modes with FreeRTOS. I have already seen videos from official ST channel and read documentation but I cannot get to set this functioning when using FreeRTOS and RTC. My goal is to blink an LED every 5 seconds and in the reamaining time go to STOP mode for low power consumption. This are my functions: void StartDefaultTask(void *argument) { /* USER CODE BEGIN defaultTask */ /* Infinite loop */ while(1) { osSemaphoreAcquire(BinarySemaphoreHandle, osWaitForever); printf("Toggle Led\n"); BSP_LED_Toggle(LED_GREEN); } /* USER CODE END defaultTask */ } /* Private application code --------------------------------------------------*/ /* USER CODE BEGIN Application */ void HAL_RTCEx_WakeUpTimerEventCallback(RTC_HandleTypeDef *hrtc) { printf("RTC Callback\n"); osSemaphoreRelease(BinarySemaphoreHandle); } void PreSleepProcessing(uint32_t ulExpectedIdleTime) { HAL_SuspendTick(); /* Start low power timer

Looking for something to try. I'm want to recover from a failed firmware update of an MLite-880 from Elecevolve after their their 1-click installer. Elecevolve suggested a manual install using the firmware binary and STM32CubeProgrammer. I can put the device in its "DFU FW update mode" and connect to the device from the STM32CubeProgrammer using USB. After connect, the log shows:08:45:07 : STM32CubeProgrammer API v2.22.0 | Windows-64Bits08:45:35 : Disconnected from device.08:46:01 : USB speed : Full Speed (12MBit/s)08:46:01 : Manuf.

Is there a guide that shows how to set up a CDC USB device on the STM32N6 without using ThreadX in baremetal mode? I've tried following both, but it seems to hardfault on both examples crash at __lib_init_array(). I've tried increasing the stack and heap sizes to no success:https://community.st.com/t5/stm32-mcus/how-to-use-stmicroelectronics-classic-usb-device-middleware-with/ta-p/599274  https://community.st.com/t5/stm32-mcus/how-to-implement-usbx-in-standalone-mode/ta-p/614435  It's frustrating that the old USB_Device middleware got removed. We shouldn't be forced to use an RTOS where it is not needed...

Hi,I'm trying to control a BLDC motor connected to B-G431-ESC1 driver in Open Loop Voltage mode. With Motor Pilot control there's no problems. I'm not able to find the correct HAL commands to use for:A) Set Open Loop Voltage mode ( B) Set the reference voltageC) Set the speed in RPMStart, Stop, Ack Fault commands are ok. AI gave me a lot of indications but nothing seems work ok. Many thanks who will help me.Bye  Rossano 

Hi, I try to get the USB-Host running with USBX. Hardware is a custom board with TCPP02 and STM32U575. Init process is running, but I never get an interrupt (ux_host_event_callback) when plugging in a USB stick. Any idea? ioc file and schematic are attached. Best regards, Achim

HiAccording to the reference manual the high-cycle capable Flash of a STM32H562 is mapped to the address 0x0900_0000 to 0x0901_7FFF. The Memory Management Tool of CubeMX does not allow me to generate a Region in this address range (see Error below). Is this correct or should CubeMX not allow the generation of a memory region in this range? The Flash Option Byte was configured for the use of the high-cycle Flash.As a work around I can of course manually edit the linker script.I use STM32CubeMX Version 6.14 with the Firmware Package V1.5.0 to generate a STM32CubeIDE project on Windows 11.  

Hie, according to the documentation of the board, USART1 can be used with db9 port by setting up JP7 and JP8 to 1 and 2 ( which I did). The second thing is to connect usart_tx and usart_rx to PB14 and PB15.The problem is that nothing is showing up on the pc with DB3 port. I've check the tx port with an oscilloscope and I'm getting signal on data sending but only 1.1 V (in AC). I don't know if it's part of the issue but I hope someone has the solutionThanks

Hey there,I'm currently working on an audio application for the STM32U5A5 (which I'll later port to the STM32N657), using MDF.The application closely follows the MDF/ADF examples for audio recording found in the U5/N6 Cube firmware packages, with the difference that it does not output the transformed audio signal immediately via SAI, but instead stores it in a large buffer to download it later via the STMCubeProgrammer.Although the application generally works great, it does not record more than ~2 seconds of audio, even if I increase the size of the storage buffer (e.g., to a size corresponding to 4 seconds of audio recording capacity). No matter how large I set the buffer, the function HAL_MDF_AcqCpltCallback is called approximately 2 seconds after the recording starts. Within the implementation of this function, HAL_MDF_AcqStop_DMA is called to stop the recording.I would be interested in the criteria according to which the HAL_MDF_AcqCpltCallback function is called. I would

Hello, I want to use an I2C port of a STM32F411 MCU (MCU_A) in target mode to receive data from another MCU (MCU_B), MCU_B code already existing and verified with other receivers.I configured the project with STM32CubeMX, with interrupts enabled to handle communication in interrupt mode.I used MX standard settings to generate CubeIDE project with HAL code.With some effort for setting up the initialization and other code for MCU_A in CubeIDE, communication looks ok from sending MCU_B perspective.Additional check of SDA and SCL signals with DSO looks ok to. But the problem was: No data was transfered to the receive data buffer in MCU_A. After several hours of debugging, I found a suspicious code section in the HAL code (stm32f4xx_hal_i2c.c).In the HAL function     static void I2C_Slave_ADDR(I2C_HandleTypeDef *hi2c, uint32_t IT2Flags)which is called in     HAL_I2C_EV_IRQHandler ()when adress matches, the direction flag received from MCU_B

Hello Community,I'm trying to interface STM32 P-NUCLEO-WB55 with ADS1293 via SPI communication protocol, But there is a issue I'm unable to read data, to verify the SPI I tried to print "Reg10 = %d\r\n" but it is returning zero as value. I'm attaching the connections diagram and ioc diagram and code file, Can anyone please help me with where I'm getting wrong..Thank you

There are 4 external events that can be chosen to trigger and reset individual counters of each HRTIM timer unit in STM32H743 MCU. CubeMX shows those events once the Event Configuration is chosen "Enabled" . Yet only Source 1 is active (allowed to be chosen) but the Source 3 that I need to connect internally to the TIM2 TRGO output is inactive (cannot be chosen) . Why? My attempts to use AI got strange results - after searching the STM documents AI concluded that CubeMX is limited , it allows only external on-pin connections and any internal connections must be manually coded in addition to the generated code. If it is so then why does CubeMX show those other options yet does not allow to choose them? Or is there way to activate those options ?Please anybody give me suggestion.Note: the STM32CubeMX is the latest downloaded and installed yesterday. The MCU library pack is also current.

Hi everyone,I’m relatively new to embedded systems, so apologies if this has already been discussed elsewhere. I’ve tried searching, but haven’t been able to find a clear solution.I’m currently developing a system based on the STM32F746G Discovery board using TouchGFX for the touchscreen UI. In addition, I’m interfacing with a distance sensor over I2C. My goal is to log data (timestamp + sensor value, already formatted) to an SD card.The issue I’m facing is the following:When I enable only SDMMC and FatFS in CubeMX, I can successfully open a file and write data to it.However, when I integrate this functionality into my full project (which includes TouchGFX, FreeRTOS, and I2C), the SD card logging no longer works.I’d really appreciate any guidance or suggestions on what might be causing this or how to approach debugging it.Thanks in advance!

Hello,I made a small USB Power Delivery trace/monitor tool using the STM32G071B-DISCO.STM32CubeMonitor-UCPD v1.4 does not correctly decode some PDO types defined in USB-PD 3.0 and later (e.g., AVS), which makes analysis difficult.So I put together a tool that can decode and visualize these PDOs more clearly.Project repository:https://github.com/aso/UCPD-MonitorExample output is shown below:[Screenshot:Apple40WSPRAVS.png]   If you have a chance to try it, I’d be interested in any feedback or suggestions.

Hi,I am trying to link up a Nucleo-F411RE board to a STLINK-V3PWR unit via the SWD (CN6) header.I am going to make a breakout board for the connector. See image below, I am assuming that I do not have to connect T_VCP_RX and T_VCP_TX to anything on the Nucleo board, am I right?

I am working with an STM32F769NI and planning to implement my own Ethernet driver without using the HAL. While studying the DMA descriptor system, I found that the hardware supports both ring structure and chain structure descriptors. However, I am having trouble understanding the exact behavior of the ring structure. For example, suppose I have three TX descriptors: DESC0, DESC1, and DESC2. After the DMA finishes transmitting DESC0, how does it advance to DESC1? Since the descriptor size is fixed, does the hardware simply move to the next descriptor by doing something like: current_descriptor_address + descriptor_size? If that is the case, then I don’t clearly understand what the practical difference is between ring mode and chain mode. So my questions are: In the STM32F769 Ethernet DMA, how exactly does the DMA engine move to the next descriptor in ring structure mode? (I would like to understand this at the hardware/register level.) What is the functional difference betw

I am trying to troubleshoot and reverse engineer a project no longer in production and for which the developer is no longer reachable.  The project is based on the ST MB997C and uses an attached daughter board that serves as an R232 communications interface to external I/O (whatever other functions it may perform are unclear).  Are there PCB suppliers that manufacture MB997C compatible PCBs to provided specifications?  The subject PCB in this project is silkscreened with the project name "ProBox V1R1", so it is not a generic OTS part.  Also, are there resources out there that can reverse engineer the functions of this PCB?  Any guidance would be greatly appreciated. 

I have created a project for the STM32WL33 several weeks ago, using the DEEPSTOP mode with context restoration provided by ST. Even if there are some pitfalls with this the project worked mostly fine. But after the update to STM32CubeIDE 2.1.0 I get a compilation error:./System/Startup/cpu_context_switch.o(CPUcontextRestore): Unknown destination type (ARM/Thumb) in ./Core/Src/system_stm32wl3x.odangerous relocation: unsupported relocationmake: *** [makefile:89: Euris3-EHKV-WMBus.elf] Error 1I've reverted the version to 2.0.0 and the error is gone.

Hi ST,I’m trying to configure the clocks for the STM32C071GBUx MCU in CubeMX (latest version, 6.17).This MCU has two SPI interfaces, two UARTs, and two I²C peripherals. However, CubeMX only allows me to configure the clock for one UART, one I²C, and no SPI at all.Am I missing something?I’ve attached the complete clock configuration diagram below.
