Hello I'm working on stm32h747 dualcore with iar & ijet with mipi-10 connector.I have a problem in CM4 jtag debug  When I try to debug the CM7 project. It always works fine. Jtag and SWD all works.And if i try to debug the CM4 with SWD method, it works fine too.But, if I try to debug CM4 project, error comes out. Success settings are: - Cm7/Swd/auto - Cm7/jtag/explict tap id=0,core no=0 - Cm4/Swd autoFailed setting is : - Cm4/jtag/explicit tap id=0,core no=1 When i try to debug cm4 with failed setting, Debug log said that cm7 at port 0, cm4 is at port3, but try to attach port1. and debug stopped with error.I think, if i change cm4 dap port number port 0 to port 3, I could debug cm4. Any advise? 

I need to flash signed bootloader and signed firmware for ardupilot the file i am using is arducopter_with_bl.hexafter this I need to erase the entire chip and need to flash unsigned bootloader and unsignedfirmware again so that i can use that again. I want to achieve this without bricking the board because once it has happend.My board does not have BOOt0 pin and it does not have DFU mode. I am using ST-LINK using SWD.If any body can help me th how to achieve this. Thanks in advance.

HiI am designing a small circular PCB with the following specifications. Due to size limitations, the antenna cannot exceed 9mm, which prevents me from achieving the recommended 4.8µH of inductance. Is it acceptable to compensate for this by increasing the matching capacitance?Additionally, I have two other questions:1. what is the recommended spacing for an NFC antenna from the edge of the PCB?2. Also, which formula do you use to calculate the inductance Circular or spiral () since I get two different results. Please let me know if you need additional information.Thank you  (mm)PCB Radios10.5N Turns3

Hello, I have modified the SubGHz_Phy_PingPong example to create separate transmitter-only and receiver-only code for two STM32WLE5 modules.I'm using the Low Level (LL) driver with UART1 interrupts on the STM32WLE5 TX module to receive data via UART, which is then transmitted over the radio. On the receiving end, the STM32WLE5 module receives the data via radio and forwards it to the target device through UART.Setup:UART ---> STM32WLE5 TX------| ( Radio ) |----------- STM32WLE5 RX ------> UARTAll data received by the STM32WLE5 TX module is handled exclusively through UART interrupts. Therefore, if interrupts are disabled, the UART will not be able to read any incoming data.In the STM32WLE5 transmitter code, Radio.Send() disables interrupts while transmitting data over the radio. During this period, UART interrupts are also disabled, preventing UART from receiving incoming data, which leads to overrun errors.Is there any possible way to p

HelloI am using STM32H7R3L8 MCU and STM32CubeIde v1.19.0. I have an issue where if I was to use SPI4 in Motorola mode together with CPOL=0 and CPHA=1, it works fine. It also works fine when I was to do SPI TX via DMA. Although, as I have the need to have CS inactive between each half-word being sent, I tried using the NSSP option of the SPI, which, when zoomed out on the logic analyzer view, seems to have an issue. Problem is, that at random points during a sequence of 1 half-word size transmits, SCLK and CS sometimes change their states at the same time, causing errors visible on logic analyzer and it seems like the slave device also can not handle that. Configuration:SPI4 in Motorola master modeHAL driverDMA transmit

Split from this thread. I did and it is all the same. Here is an example when I measure on port PB1 the voltage from VREF divided by 3 (2.5V/3 = 0,833..V).

Hello,I have an issue with the CAN bus on STM32F042G6 µC. For the moment I just want to receive Frames from an other controller (STM32G0B1) and it doesn't work at all.I am using PA11 as Rx Pin and PA12 as Tx Pin Pins.Here is the configuration part with a 12MHz external clock :static void MX_CAN_Init(void) { /* USER CODE BEGIN CAN_Init 0 */ /* USER CODE END CAN_Init 0 */ /* USER CODE BEGIN CAN_Init 1 */ /* USER CODE END CAN_Init 1 */ hcan.Instance = CAN; hcan.Init.Prescaler = 16; hcan.Init.Mode = CAN_MODE_NORMAL; hcan.Init.SyncJumpWidth = CAN_SJW_1TQ; hcan.Init.TimeSeg1 = CAN_BS1_1TQ; hcan.Init.TimeSeg2 = CAN_BS2_1TQ; hcan.Init.TimeTriggeredMode = DISABLE; hcan.Init.AutoBusOff = DISABLE; hcan.Init.AutoWakeUp = DISABLE; hcan.Init.AutoRetransmission = DISABLE; hcan.Init.ReceiveFifoLocked = DISABLE; hcan.Init.TransmitFifoPriority = DISABLE; if (HAL_CAN_Init(&hcan) != HAL_OK) { Er

Dear ST Community.I am designing devices with STM32WL microcontrollers with highly limited board space. I routed out traces for all SWD signals (VDD, GND, NRST, SWDIO, SWCLK)I have my Prototype Board, original ST-Link V2 with V2J45S7 Firmware and STM32CubeProgrammer version v2.20.0. During testing I realized that the connection to Prototype is stable only when I connect all 5 signals. For some reason I thought that "VDD_Target" pin on ST-Link side can be left floating.I have found a previous post:https://community.st.com/t5/stm32-mcus-boards-and-hardware/how-to-connect-the-stlink-v2-to-my-board/m-p/94389but unfortunately in my case I have to have "VDD_Target" signal connected on both ends. When disconnected STMCubeProgrammer responds with error shown below:

Hey here is my FLASH.ID :  I want to use more of the ram . I am using : STMicroelectronics Arm Cortex-M4 MCU, 320KB flash, 48KB RAM, 64 MHz, 1.71-3.6V, 30 GPIO, UFQFPN48   STM32WB15CCU6 .. So i should have more RAM. but I am nor sure how to adjust the memory so I can use it.  Currently as you can see. I am using the p2p OTA example, in which initially the FLASH was configured to be very small, and i extended that, but now the RAM is twice as less than what i should be able to use . Can you help me with this? Thanks!MEMORY{FLASH (rx) : ORIGIN = 0x08007000, LENGTH = 135KRAM1 (xrw) : ORIGIN = 0x20000008, LENGTH = 0x2FF8RAM_SHARED (xrw) : ORIGIN = 0x20030000, LENGTH = 10K}

Environment:- STM32Cube VSCode Extension (with Build Analyzer)- CMake-based project generated by STM32CubeMX- Windows 11 / GCC toolchainIssue:- The Build Analyzer fails to detect the .map file and reports "NO_MAP_FILE".- Investigation shows that the analyzer seems to only look for a .map file named after the *project folder*(e.g. build/Debug/<project_folder>.map).- However, in CMake projects the actual build target name is derived from ${CMAKE_PROJECT_NAME}, which can differfrom the folder name.(In my case: project name = VaporChamberController_V2, folder name = VaporChamberController_V2_vscode).Steps to reproduce:1. Create a project where the folder name and project name are different.2. Build the project with CMake.3. A .map file is generated (using the target name), but the Build Analyzer shows "NO_MAP_FILE".Workaround:- Manually force the linker to generate a .map file with t

Hi team. We have been using the STM32F373VCT6 microcontroller across three different projects for the past three years. However, during testing and debugging time we’ve encountered a recurring issue where the controller is getting short between the 3.3V supply and ground suddenly. This problem has occurred multiple times and is affecting our development process. We kindly request your support in identifying the root cause of this problem.  

Hi there! This might be a silly question, but I'm truly having trouble to find any documentation concerning the new User Actions feature, what are its functionalities, and how does it work. Unfortunally, it is not even mentioned in the UM1718 User manualAlso, the only mention I even found of this feature is in this forum question Could anyone please refer me to some documentation on the topic? Thanks in advance! 

I am writing some firmware for a device with an alpha-numeric display. The display language must be changable. For most languages, this means using characters outside the A-Z range. UTF-8 covers most of the necessary characters.In the project properties, I found this setting, and naively thought that the UTF-8 selection included the actual compiler:Well, obviously not, as it is GCC that needs to know that the character set is to be UTF-8. The codesprintf(pString, "Français");is translated tosprintf(pString, "F

Hello,I would like to use the TFM application on STM32CubeIDE for the B-U585I-IOT02A board but I can't find the application anywhere. Any help?

Hi there ! I hope someone can help me with a confusion i had in my mind right now. I work with a EEPROM 24C256 and need a write a lot of data inside , soo i decide to use the page write solution . So from the datasheet i saw i can write 64byte in one shot. and here i have a doubt. if i start from the address 0x00 i know i can write until 0x3F.But if i start to write from 0x10 i can write until 0x3F right of course not 64Byte but 48Bytes is it right ?    Thank you  Sergio   

Hi there. I require assistance to ensure the proper operation of GT9271.After properly RESETting the GT9271, and issuing the 0XBA I2C address, the device keeps pulling the INT pin without any touch on the LCD display (1024x600). I really feel a lack of information, and the datasheet does not give a good description of the registers.This is my code!#include <main.h> #include <DLY.h> #include <stdint.h> uint8_t FLAG_TP, CXY_BFR[4]; uint16_t TPX, TPY; uint8_t TP_CNF_INIT[]= //188b { 0X00, //REGISTER_HIGH 0X00, //REGISTER LOW 0X81, //0X8047 -> 0b10000001 0X00, //0X8048 -> 0b00000000 X-> OUTPUT MAX LOW BYTE 0X04, //0X8049 -> 0b00000100 X-> OUTPUT MAX HIGH BYTE (0X0400 = 1024) 0X58, //0X804A -> 0b01011000 Y-> OUTPUT MAX LOW BYTE 0X02, //0X804B -> 0b00000010 Y-> OUTPUT MAX HIGH BYTE (0X0258 = 600) 0X01, //0X804C -> 0b00001010 TOUCH NUMBER -> 1 POINT ONLY 0X00, //0X8

Hi!My STM32F207 behave funny when i "blx r3" from 0x800'0344 (FLASH) to 0x870 (lower 112KiB SRAM mapped to 0x0):It seems to ignore the first 4 bytes of instructions... When i insert 4 nops at 0x870 (or "DSB();ISB();"), then everything works as expected:int main() { { dbgb[0]=0xAFFE0000; asm("nop\n nop\n nop\n nop"); } { dbgb[19]=__SP(); for (u32 i=0; i<16; i++) dbgb[i]=0xABBA0000|i; } { dbgb[8]=__get_MSP(); dbgb[10]=__get_PSP(); dbgb[12]=__SP(); } { dbgb[0]=0xAFFEABBA; bla(); dbgb[1]=0xAFFEBEEB; } { dbgb[9]=__get_MSP(); dbgb[11]=__get_PSP(); dbgb[13]=__SP(); reset(); return 0; } init(); if (!mainrptver(0)) reset(); SET_BIT(SCB->SCR,SCB_SCR_SLEEPONEXIT_Msk); __WFI(); } void Reset_Handler() { dbgb[16]=__get_MSP(); main(); }the code in the flash is this (P is a u32* to 0x2000'0000):SYSCFG->MEMRMP = (0b11 << SYSCFG_MEMRMP_MEM_MODE

I guess I have found a Bug in the G473RC debug launch script:I have a STM32G473RC MCU with 128k RAM and 256k Flash.As long as the Flash File stays below the size of 128k all works fine. I can develop, test and debug with CubeIDE. As soon as the flash file becomes larger than 128k, I can no longer debug the Software, because the Launch of the debugger exits with an error message:

Hello, I have the same problem but with the new version STM32CubeIDE_1.19.0. All the symptoms are the same as in this post but in the STM32G473RB processor and when the firmware becomes more than 64KB.  

Hello,We are currently working on a project that requires integrating FreeRTOS with the STM32_WPAN BLE Stack. Based on various forum discussions, it seems that configuring the BLE portion of the project using CubeMX is currently not feasible.However, as we are still in the early stages of development, we would like to retain the convenience and simplicity that CubeMX provides for setup and configuration. To address this, we have decided to split the project into two separate projects:FreeRTOS and other application-related hardware/software functionality.Bluetooth functionality using the STM32_WPAN BLE Stack.Once both projects have been sufficiently developed, our plan is to merge them into a single project and continue develop

I'm using the STM32G474RE with STM32CubeIDE - Version: 1.19.0, and I encountered a strange issue. I'm not sure whether to call it an error, as it doesn't technically throw any errors—but it's unusual.When I create a new project and open the .ioc configuration, the NVIC section (which usually shows 7-8 entries for code generation) is completely empty. This behavior seems abnormal, and I'm unsure what's causing it.Could someone please help me understand what's going on or how to resolve this?

System Details:MCSDK Version: 6.4Tool: MC Workbench 6.4.0Control Board: B-G431B-ESC1Motor: GL40 KV210Encoder: AS5047P with quadrature outputHello,I'm new to BLDC and FOC motor control and am currently trying to implement speed control using a quadrature encoder with my B-G431B-ESC1 board and GL40 KV210 motor. I've reviewed the manual and various forum posts regarding similar issues, but haven't found a solution.My primary problem is that while the setup functions correctly in sensorless mode, open-loop voltage, and open-loop current modes, encoder-based speed control is not working. Interestingly, the speed and direction calculated by the encoder align with the estimates from the sensorless approach.I suspect the issue lies with the encoder alignment process. I've observed the `stopll_el_angle` and `enc_el_angle` plots before and after alignment (as shown in the attached picture). During the alignment process, I plotted `I_q_

Hi all,I'm looking for an example (STM32CubeIDE) allowing to call a function located in RAM in order to copy flash bank2 to flash bank1 and then restart the CPU.Regards,

We are creating a driver for a W25Q128JV Winbond Nor Flash chip. We are working with a STM32 H743ZI2 board and communicating on the QSPI peripheral with the help of the HAL libraries. Currently the driver can successfully Write to the chip using standard Page Program (0x02h) and the Quad Page Program (0x32h). We are also successfully doing a Fast Read (0x0Bh) up to speeds of 72MHz and a Fast Read Dual Output (0x3Bh) up to speeds of 36MHz before they start to fail. Currently we are using a 3.3V power bus, so based on the AC Electrical Characteristics seen in the datasheet we expect these commands to work up to speeds of 133MHz.Below is the CubeMX setup we are using for the QSPI peripheral:
