I’m interested in STM32H5 series (since it’s based on a M33 core which offers performance and security).I need to execute FFT and FIR filtering functions in real time and so I’ve been investigating on hardware accelerators available on the MCU.I see there are CORDIC and FMAC, but I don’t find a specific mention to FFT (like NXP does for PowerQuad).So I wonder if they can be used to perform hardware-optimized FFT.And I wonder if ST has some benchmarks (with sample code) for hardware accelerated FFT on STM32H5.Thanks

Hello,This is for test BOOT1 jumper is set to HIGH for development (DEV boot mode) I have a simple LED blink application built with GPIO configured in the FSBL context The code runs as expected in DEV mode (debug mode of STM32CubeIDE) I then flashed the signed binary in external memory using STM32CubeProgrammer and External Memory loader for Nucleo-N6 board at address 0x70000000.  Then, I switched BOOT-1 jumper to LOW and reset the board. The code runs as expected from external memory  Edit: new test 😀

Hi,When using this, single-character text isn't perfectly centered on the button,the letter appears slightly higher.Also, characters like .,_ appear higher than they should.Is it possible to adjust the text position horizontally when using these?

Hello all,I’m working with an STM32 microcontroller (specifically the STM32H743), and I have a question regarding the use of an external TCXO as the HSE clock source.As per the datasheet, when using an external clock source (such as a TCXO), the HSE must be configured in bypass mode, and the input clock is expected to meet the digital I/O thresholds (e.g., 0.7 × VDD for logic high). However, many high-quality TCXOs have typical output swings of only 0.8–1 Vp-p (clipped sine wave), which do not meet CMOS thresholds when VDD is 3.3 V.Therefore, directly driving OSC_IN with such a TCXO in bypass mode is not viable per the datasheet.That said, I made an observation I’d like to confirm with you:While using a crystal in crystal resonator mode (not bypass), I probed the OSC_IN pin using a low-capacitance active probe and measured a signal of approximately 1 Vp-p. Since this amplitude is generated internally by the oscillator circuit when using a crystal, it seems the STM32’s HSE input is desi

Hello, I am trying to load a kernel driver (.ko file) for a MIPI camera I would like to use with the STM32MP257F-DK. It's for the imx664, and no driver is present already. I have the source for the driver, and was able to compile it into a .ko file, cross-compiled with the exact same OS as is present on the board and with the SDK set up as required. The vermagic line matches exactly: vermagic: 6.6.78 SMP preempt mod_unload aarch64However, every time I try and load the driver with insmod, with or without -f, I get the error: insmod: ERROR: could not insert module imx664.ko: Invalid module formatI am struggling to find where the incompatibility could be, since I have re-tried it a few times and been careful to set it up as ST's documentation says and also to match what is expected by the board. Is there something I am missing with this?

The STM32G031G8U6 in a UFQFPN28 package does not have PF0 / PF1 pins for HSE OSC_IN / OSC_OUT.  It does however have OSC_IN on PC14.  This is intended for an external CMOS oscillator in bypass mode.I’m currently in the schematic design stage. My board clock is a clipped-sine TCXO used for other purposes.  In some modes, I’d like to use it to clock the STM32. I’m very constrained on cost, power, and board space.  The clipped-sine doesn't meet the voltage level requirements for a bypass-mode clock.Is it possible to configure HSE as if it were a crystal, but instead supply a clipped-sine 0.8 Vpp clock from the TCXO to PC14 OSC_IN? Does the die used in UFQFPN28 even have the HSE oscillator circuit that exists in the 48 pin package?I would set RCC_CR[HSEBYP] = 0 and RCC_CR[HSEON] = 1.  I don’t see any register controlling the OSC_IN alternate function on PC14.  STM32CubeIDE doesn't allow this configuration, unsurprisingly, but I would configure t

Hello everyone,I'm working with the STM32L562E-DK board and the STM32Cube_FW_L5_V1.5.0 firmware. I want to integrate my own code (which reads a sensor MPU6050 via I2C) into the STM32CubeL5 TFM (Trusted Firmware-M) application, running it in the Non Secure environment. The base project I'm using is TFM_Appli, which comes in the package, and I've added my source code to the NonSecure section.I created a separate project in STM32CubeMX using the board's I2C1, which utilizes pins PB6 (SCL) and PB7 (SDA). I ​​then generated the code and copied the I2C communication initialization code into the "main.c" file of my "TFM_Appli_NonSecure" project. Specifically:/* This is before "int main (void)"-----------------------*/ I2C_HandleTypeDef hi2c1;/*------------- I'm calling these function from "int main(void)" ------------*/ static void MX_GPIO_Init(void) { /* USER CODE BEGIN MX_GPIO_Init_1 */ /* USER CODE END MX_GPIO_Init_1 */ /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOB_CLK_ENABLE(); __H

In STM32CubeIDE, I can compile C++ code in the project. The CMake file generated for the VSCode extension doesn't work with C++. Is there a way to use C++ code with less hassle than trying to get around this by hand?

I have an issue were the Linux kernel is booting, then it just stops printing out messages from USART6.Meanwhile, optee, u-boot and TF-a is printing out messages from USART6. But not Linux after a while.What can have caused this?My processor is: STM32MP257F.

Hello everyone,   i want to build a CAN FD network with three NUCLEO-C092RC boards. So far i can transmit frames, as i can see on an oscilloscope. But the moment i connect TWO boards, the interrupt is not triggered. My code should activate user LED2 if it receives a frame with one specific id: Board 1 (0x101) triggers LED when receiving message 0x344 or 0x234 Board 2 (0x234) triggers LED when receiving message 0x344 or 0x101 Board 3 (0x344) triggers LED when receiving message 0x101 or 0x234   i use a nom. baudrate of around 500 kbit/s and data baudrate of 1 Mbit/s with a clock of 40 MHz (HSE). The Boards are connected with two short (10cm) twisted jumper cables and the jumpers for the 120 Ohm resistor are also plugged in on both baords. when i test it in external loopback mode, it works (with ident. change) Could this just be a problem with my wires (reflexion , parasi. C ,etc.)?   thanks a lot for the help

Hello. I've a problem regarding LSE On stm32l562xx mcu. Sometimes it boots, sometimes it doesn't "90 % of time it generates timeout Error" . and it takes too much time to boot up to 4 seconds. I've tried all your sdk initializations, also tried setting lse drive to all 4 modes but nothing changes. Same behaviour and same time. Below is my initialization code and attached how we connect LSE on our board.
