 I’m encountering an issue with XSPI1 in my application. I boot the application via XSPI2 in an LRUN configuration, and this part works perfectly. However, within the application, I need to use XSPI1 to write data to a different flash.During MX_XSPI1_Init(), the code crashes at this line:if (HAL_XSPIM_Config(&hxspi1, &sXspiManagerCfg, HAL_XSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK){Error_Handler();}I traced the crash to the exact line:IOM_cfg[0].IOPort = pCfg->IOPort;The initialization code for XSPI1 was generated using CubeMX. Interestingly, if I initialize XSPI1 in the boot project, everything works fine.I’ve already spent a week trying to solve this issue, but so far nothing has worked.I would re

Hello,I am trying to set up  a UPD communication with a nucleo-H755ZI-Q board.Now I have the effect, that the lwip stack sends out an arp request for its own IP address.I double-checked the IP address and destination address to make sure they were correct. Does anyone have any idea, what could be causing this?Thank you.HiSt

Hello,I am trying to configure the secure memory in Secure Protection Bank 1 of options bytes section and for this I have followed the STM32 MOOC tutorial to understand the concept of using secure boot code. But I am facing issues as the base address for Bank 1 is expected be 0x08000000 as mentioned in STM32 G4 system memory protection document and also in tutorial whereas its showing as 0x00000000 Below is the screenshot from STMCube Programmer Optio

Hello,I have a question regarding the STM32WBA55G-DK1 board I have on hand.On my board, R42 is not populated. Could you please confirm whether R42 is not mounted by default?R42 is a 0 Ω resistor located on the control line of the general-purpose LED (LD3), and according to the schematic it appears to be mounted.I would appreciate it if someone could clarify this.Thank you in advance.

Hi, I've created a project with cubemx, copying the configuration generated with touchgfx designer for this board with the only change being that I wish to use threadx instead of FreeRTOS.  I'm able to compile and flash to the board and after hours of debugging I can't seem to find what the issue might be, everything seems to be working fine but all I get is a blank screen.  I've updated the linker script to use external ram (just as it is when generating the project via touchgfx designer) and when debugging I can step through the boot and application program no issue, no errors or faults.  Has anyone run into this before and got out of it?  I tried just about everything that I can think of at this point.  Additional info:-Stm32CubeIDE Version: 1.18.1-Stm32CubeMX Version: 6.14.1-Touchgfx Designer Version: 4.25.0-Threadx version: 6.4.0-Touchgfx generator version: 4.25.0Thank you.

Hello, I am working with the LL_ATON library on STM32N6 and testing the LL_ARITHACC unit using the AFFINE operation, defined as: Output=A⋅X+B⋅Y+C.I ran several tests with a simple network model whose only purpose is X + Y.My expectation is:Case 1: A = 0, B = 0, C = 1→ Output is correctly constant 1 as expected.Case 2: A = 1, B = 0, C = 0→ Expected output = X, but the results are completely wrong and look like random values.Case 3: A = 0, B = 1, C = 0→ Expected output = Y, but again the results are incorre

in app_freertos.c, the hook prototypes are not all defined as __weak.  This requires either deleting those prototypes or rewriting them with the __weak attribute to avoid multiple definitions when they're actually used in user code.  I generally do not like to modify the IOC provided code unless it's main.c.  Even though there are user sections, I'd like to have to modify as few things as possible to get a working projectI do use the hook prototypes frequently, but the hook definitions are autogenerated and not in a user area.Please change your code to add the __weak attribute, as shown in the segment below.  I've got them commented out because I transplanted the definitions into the user area so I would at least keep them./* Hook prototypes */ //__weak void configureTimerForRunTimeStats(void); //__weak unsigned long getRunTimeCounterValue(void); //__weak void vApplicationStackOverflowHoo

To get my first sensor project done and after selecting my board, I enabled I2C1 which triggered pins PB6 and PB7 as shown below: Then used code below (in main.c) with the purpose that the LED is on when the temperature is higher than 40 degrees and off otherwise.  #include "main.h" extern I2C_HandleTypeDef hi2c1; // I2C handle from CubeMX #define HTU21D_ADDR (0x40 << 1) // 7-bit address shifted for HAL #define TRIGGER_TEMP_MEASURE_HOLD 0xE3 I2C_HandleTypeDef hi2c1; UART_HandleTypeDef huart2; void SystemClock_Config(void); static v

I'm using the STM32F401RE in a new design and trying connect the USB CDC device interface to FreeRTOS_CLI. I modified its _write function to call CDC_Transmit_FS, but I don't see a received data callback where I can add a xTaskNotifyFromISRfor to send data to the CLI task.It looks like I call CDC_Receive_FS to get the data, but I need an interrupt to trigger the call to that function. Where can I hook in a callback function?

STM32CubeMx version is 6.12.1.The power and thermal option is not available for STM32G474xx devices project in STM32CubeMx.The same is available for the STM32U5Xxx devices project. How to set the wake-up modes if the power and thermal option is not available? 

Hello,I am developing an embedded project using the STM32H7 microcontroller, integrating FreeRTOS, FatFs file system, USB mass storage device (USB flash drive) functionality, SD card reading/writing,UART communication, and ADC sampling. My system uses LVGL as the graphical user interface (GUI) library and drives the LCD through LTDC.Core issue phenomenon:I observed that the system's functional behavior has a direct and consistent correlation with the on/off state of the LVGL screen:DISPLAY_ENABLE is a macro definition I created to control whether to use the screen.When the screen is off (DISPLAY_ENABLE = 0):All functional modules (USB mass storage mounting and writing, UART communication, ADC sampling, SD card reading/writing, database operations) work normally.When the screen is on (DISPLAY_ENABLE = 1), two different phenomena occur:Phenomenon 1: When test buffers (writeBuffer/readBuffer, 512 bytes each) are located in the d

Hello, I am trying to follow the Getting started with the STEVAL-WLC38RX document for FOD tuning attached. I am using STEVAL-WBC86TX, powered from a bench top PSU,  and STEVAL-WLC38RX, connected to an electronic load. Both are connected to the STMGUI. Following section 9.4 on page 60 of the above mentioned document. I have set all BPP FOD values to 0. When using the RX FOD tuning page, as per the document, the Prx value is being read correctly. However, the Ptx value is continuously reported as 1084. This value does not change despite and current draw increasing on the PSU.Why is it that the Ptx value is not changing?Kind regards,Lewis

Hello there, I'm using a STM32G431KBU and programming it using STM32 Cube IDE.There are 2 pins, PB4 and PB6, both digital inputs, I'm having problem with. On both, I apply 5V with a 10K pull-up resistor, while the MCU is working is at 3V3, this should work fine, as both are five-volts tolerant (FT), as per datasheet. When connected to the pull-up resistor, the voltage on the pin drops to 1V7 - 1V6, while there is 3V3 on the pull-up resistor. It looks like there is a pull-down resistor configured on these pins, and according to the DS, these pull-down resistors are controlled by the level on PA9 and PA10:

Hi,I recently started working on a custom board using the STM32U5G9ZJT6Q microcontroller. I'm planning on using TouchGFX with LTDC, DMA2D and GPU2D to implement a graphical user interface and AzureRTOS as rtos.I am encountering a problem when, in the main function, the microcontroller hard faults during the MX_TouchGFX_PreOSInit function, in particular at the FrontendHeap& heap = FrontendHeap::getInstance() call.I am using STM32CubeIde 1.19.0 with STM32CubeMX 6.15.0 and TouchGFX 4.25.0. I also tried with TouchGFX 4.24.2 with no luck unfortunately.Here are the screenshots of the hard fault info, stacktrace, and disassembly as shown by STM32CubeIde:

Hi all, I am working on a project based on the STM32WB55MMG, where I want to use the AES module to encrypt data using a previsouly programmed key in the FUS.I have downloaded the corresponding key with the command STM32_Programmer_CLI.exe -c port=JTAG -wusrkey XXX_key.bin keytype=1 but it would seem that the key has been written in index 1, not 0 as I was expecting. If I try to load the key using SHCI_C2_FUS_LoadUsrKey(0) it returns SHCI_FUS_CMD_NOT_SUPPORTED but if I try with index 1 instead it returns SHCI_SUCCESS.I cannot confirm the written index as the command line did not return the actual index where the key was written. In fact, I think this is a known issue when downloading a key using SWD.My question is if index 0 is reserved for another purpose and actually the first slot that can effectively be written with a general user key is 1. Thanks in advance.

Hi !I have troubles with using cmake and STM32CubeIDE on my laptop: I am trying to compile a project, and when I use the build (hammer) button, it errors out with this:**** CMake Configure of configuration Debug for project gamma_focal ****C:\Program Files\CMake\bin\cmake.exe -S . -B build/Debug -GUnix Makefiles -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ONCannot run program: "cmake": Ensure CMake is installed and available from the system PATH. However, when I type the command in my terminal, it works nicely (I have to insert quotes to format the shell command

Hello,I am running a BLDC motor in sensorless mode using Nucleo-F101RE with the X-Nucleo-IHM16M1 board. The motor starts successfully when I press the Start button from the Motor Pilot GUI.However, I am facing the following issues:When I suddenly increase the speed to high RPM, I get a speed feedback fault.When I suddenly decrease the speed, I also get a speed feedback fault.Sometimes I also encounter an overvoltage fault during these speed changes.Any guidance on how to resolve or tune the parameters properly would be very helpful.Thank youBest RegardsRahul

I am using stm32 303e eval , i want to display an image on the in built lcd mounted on the mcu . i am using touchgfx,cubemx and IAR workbench. In touch gfx this mcu does not appear so i started with cubemx with initial peripherals then i go to touch gfx and then to IAR workbench my code is running but nothing appears on the lcd.psi am using stm32 303e eval mcu with touchgfx,cubemx,IAR workbench. since this board is not available on touch gfx i started my project with cube mx selected this board then went to touch gfx.During debugging it is not stepping into if statement provided in gpio pin configuration lcd pin is low i am using non rtos path and nothing is appearing on the screen but there is no error in the code

We are testing the STM32F407G-DISC1 development board and trying to use an external 32.768 kHz LSE oscillator for RTC clock source. Since the onboard crystal footprint was empty, we manually soldered the following components on the LSE pins (PC14 and PC15):Crystal oscillator: ABS25-32.768KHZ-4-T from Abracon(Product link: https://robu.in/product/abs25-32-768khz-4-t-abracon/#tab-specification)Load capacitors: CC0603CRNPO9BN6R8 (Recommended value per crystal datasheet)Despite carefully soldering the components and verifying the connections, RTC initialization (HAL_RTC_Init) always fails with error code 1 (HAL_ERROR).I have attached my main.c

Hi Team,I have used this part EMIF06-MSD04F3 in my design.Now i'm moving ahead for production.Is there any drop in replacement or recommended alternates?Thanks Manikandan R

Hello,I’m testing a motor with integrated Hall sensors for which I don’t have the datasheet and that I can’t disassemble. From the tests I’ve done, it appears to be a 4-pole motor with Hall sensors spaced 120 mechanical degrees apart.I first tested the motor in voltage mode without using the Hall sensors: it runs smoothly, doesn’t overheat, and spins correctly, so the pole count seems right. Then, I moved jumpers 5, 6, and 7 to connect the Hall signals to the microcontroller, powered them at 5 V with jumper 3, and checked the H1, H2, H3 sequence with an oscilloscope. The signals are present and in sequence.However, when I try to start the motor, it needs a manual push to get going and then it immediately ramps up to maximum speed. Also, I don’t see any speed feedback on the Motor Pilot, and I can’t change the target speed. If I try enabling polling of HALL_SPEED or HALL_EL_ANGLE from the registers, I get the following log error:[WARNING] - MotorCon
