Hi everyone,I’m working on a product using the STM32WB55 with BLE and Zigbee static concurrency, and it’s now moving into the FCC certification stage.I’ve come across the Phy_802_15_4_Cli application along with the wireless coprocessor firmware (stm32wb5x_Phy_802_15_4_fw.bin), and I want to confirm whether it covers the requirements for test mode.My requirements are:1. Continuous transmission (both unmodulated and modulated) on a single channel2. Channel selection (e.g., 2402, 2440, 2480 MHz for low, mid, high)3. Maximum duty cycle (100%) transmission4. Fixed transmit power at the maximum rated level5. Option to enable hopping/modulation patterns (for BLE)From what I’ve seen, the Phy_802_15_4_Cli application seems to provide almost everything except hopping. Would this application be sufficient for FCC test cases?Also, has anyone here used other applications or tools for FCC or similar certification testing?

Hi,I am working with the STM32F103RCT6. I am writing a bare metal code for delay function using SYSTICK timer. The problem I am facing is that I am not able to write to the ARM cortex registers. Below is my code for your reference - This is the stm32f103xx.h file#define SYSCLK 8000000UL // System clock frequency in Hz #define SYSTICK_BASE 0xE000E010UL // SysTick Structure definition typedef struct { volatile uint32_t CTRL; /* SysTick control and status register offset: 0x00 */ volatile uint32_t LOAD; /* SysTick reload value register offset: 0x04 */ volatile uint32_t VAL; /* SysTick current value register offset: 0x08 */ volatile uint32_t CALIB; /* SysTick calibration value register offset: 0x0C */ } SysTick_TypeDef; #define SYSTICK ((SysTick_TypeDef *) SYSTICK_BASE)This is the function in my main.c - v

Hello,I am designing a custom board with stm32mp257,As given in evm it is connected with 4GB eMMC on SDMMC2, But I require 32GB 0r 64GB, can you suggest some eMMC for it.Best RegardsAbhineet Ranjan

I'm looking for an example to use as the starting point for a sensor data collector. In particular, an  STM32F401 ADC_MultichannelSingleConversion with DMA and software start. I found an example for the F11 that is based on the LL SDK. I then created an F401 project using ADC with DMA and set the code generator to utilize the LL SDK for those components. I then compared the 'stm32f4xx_it' source and header files and found them substantially different. So much so, in fact, that I'm unsure how to proceed. The F11 example does not have an IOC file, so I cannot view its configuration settings. The code generated from my IOC file features very nice blocks that delineate where user code should be placed, and I want to utilize this feature to avoid conflicts with the code generator as I add other system components.The same applies to the 'main' source and header files. If there's a better example to use as a starting point, or some guidance for merging the example code into a S

Hi all, I have an STM32H743 project that I've been working on. I've worked on a fair amount of projects in STM32CubeIDE in the past, but now I have a problem I haven't encountered before: the linker is putting my .bss section in flash as well as RAM. I'm not sure why an uninitialized section would be placed in flash... I've attached the output from the build analyzer as well as my linker script. The script is almost the default, except that I've added D2/D3 RAM and have moved stack & heap to DTCM. I've used very similar scripts in other projects and BSS ends up only in RAM in those projects.Can anyone find what I'm doing wrong? Thanks! 

Hello,I am working with the STM32N6570-DK and following the steps described in the following article to write the FSBL and application to flash and verify their operation:https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206Specifically, I am referring to section 2.2: "Second demo with FSBL and application".However, I was unable to observe the LED blinking as expected.While investigating the issue, I came across the following discussion:https://community.st.com/t5/stm32-mcus-boards-and-hardware/nucleo-n657x0-q-failed-to-start-gdb-server/td-p/756404/highlight/true/page/2After reviewing this and checking the OTP val

Hi everyone,I'm trying to interface an SD card over SPI with an STM32F411. However, I cannot even initialize it. My current sequence is:Wait 20 ms after power-on.Send 10 clock cycles with CS high.Pull CS low and send CMD0 and wait for a reponse.Instead, I only ever receive 0xFF instead of 0x01.My SPI configuration looks like this:Here is the relevant code: MY_DEBUG_PRINTLN("Hello World"); uint8_t txBuf[6]; uint8_t resp = 0x00; uint8_t dummy = 0xFF; HAL_Delay(20); MY_DEBUG_PRINT("Raw SD

We're using the ADC function built into the STM32F767.The problem is that when the analog signal input to the ADC is around 200mV, the digital value output from the ADC appears to be around 240-260. We're trying to obtain a stable value by collecting 60 of these digital values ​​and calculating a moving average.However, quite often, out of the 60 data points, 20-30 values ​​exceed 3000. Therefore, even when averaging the data, the readings are completely different from the actual analog value.When I measured the input analog signal with an oscilloscope, it was around 200mV +/- 40mV, so I don't think it's due to input signal noise.I suspect there's something wrong with the MCU's ADC settings or program. Please advise on what I suspect.

Hello, I saw a thread titled Your Input Matters: How Do You Use STM32Cube Examples?And I tried to enter to the examples selector of CubeIde (I never tried before).When I open the selector, my computer takes several minutes with the cpu fan at highest speed. After this, I tried to select a board to reduce posibilities, and happened the same, but I had a memory full error.The only way to continue is to kill CubeIde. It's impossible to close it safely.But now CubeIde does not start. It ask me the workspace, and shows the picture of screenshot I attached.If I select a different workspace, it works. And now, my questions are...Can I restore

I am trying to configure a USB-C connector on a peripheral device to detect VBUS via GPIO (PH9). I have tried several iterations using the following device tree documentation.- 3.3.1. DT configuration example as high speed OTG, with micro-B connector, Vbus and ID mapped on GPIOs- 3.3.3 DT configuration example as USB2-speed only USB3DR in Peripheral mode, with micro-B(ID left unconnected) or Type-C connectorThe only way I have been able to get USB traffic to occur is by using the

TL;DR - adding USBX and the USB CDC device class to my STM32U5 TouchGFX project causes it to fail during initialization, because the default memory settings are woefully inadequate.I have a TouchGFX project running on an STM32U5G9J-DK2 using ThreadX.  The TouchGFX component tosses up a splashscreen, and I have other tasks running, including a debug task putting out UART data.  So that all works fine.What doesn't work is when I add USBX and a simple USB CDC device class to the project.  I can add it using CubeMX, but when I build and run it, it dies during initialization because of memory allocation issues.  I would at least expect it to run out-of-the-box when adding it to a new or existing project.Here are my steps to reproduce the failure:Make a workspace directory (I called mine C:\ST\workspace\touchgfx_usb_issue).Open TouchGFX, create a new project, select STM32U5G9J Discovery Kit 2 running ThreadX, select the wo

Hi all,I'm currently working on a project using a STM32H753 in combination with the Azure RTOS UsbX to create a composite class USB device (CDC ACM + MSC). As a starting point for the MSC support, I'm using this STM github example:https://github.com/STMicroelectronics/x-cube-azrtos-h7/tree/main/Projects/STM32H735G-DK/Applications/USBX/Ux_Device_MSC Unfortunately, my board only supports a 1-bit SD bus which is running at 48MHz. The composite class is working along I'm using the HAL_SD_WriteBlocks_IT / HAL_SD_ReadBlocks_IT functions. By using the IT driven approach, Windows is able to mount the SD card and I can create, edit or delete files as expected.Changing to the DMA driven functions, then the mount seems to fail, has corrupt disk nam

Hi Team, I am planning to use STM32L476RE MCU for my project, Can I know how to switch between Stop1,2 and low power sleep and run modes? I am new to STM32 and I need a reference code or some guidance to start with, any help very much appreciated. Thanks in advance,CH. Pranathi

We are developing a product that needs the ability to run 3 separate CAN interfaces connected to 3 separate CAN buses.  I have the NUCLEO-F413ZH and I can successfully initialize and start CAN1, CAN2, and CAN3 and transmit from each of them in a single application, but I only get RX interrupts on CAN3 when all 3 interfaces are initialized and started.  Additionally, if I only initialize and start CAN1 or CAN3 in my application, I can transmit and receive from them, but not CAN2.Pages 1076-1077 of the part datasheet/reference manual (RM0430) lists dual and single CAN peripheral configurations:

Hi,Im just getting my new STM32N6570-DK and I try blinking simple led project first with default generate.But when I built and flash it, it got stuck when init UCPD (pic 1), am I missing something ?When I checking seem it still not define yet (pic 2).Thanks 

Dear ST Community, I'm developing a Zigbee sensor node using an STM32WB55RG Nucleo board as an end device that should join my existing Zigbee network (Raspberry Pi 4 + CC2531 running Zigbee2MQTT). Despite successful build and flash operations, my STM32WB55 won't join the network, and I'm not seeing any LED feedback despite setting CFG_FULL_LOW_POWER=0. My SetupCoordinator: Raspberry Pi 4 + CC2531 (Zigbee2MQTT)PAN ID: 46212 (0xB484)Channel: 15Network Key: [117, 131, 80, 245, 206, 246, 76, 112, 61, 246, 117, 178, 116, 246, 135, 64]End Device: STM32WB55RG NucleoSTM32CubeIDE: 1.13.0STM32CubeWB: 1.23.0Wireless Coprocessor Firmware: STM32WB5x_BLE_Zigbee_RFD_dynamic_fw.bin (flashed to M0+ core)Application Example: BLE_Zigbee_Dyn_SED (chosen specifically as it's de

Hi,I am not able to output per I2S properly.1. I changed from a properly working driver for STM32F407 to this STM32H7A3VGTI had to learn, that the master clock is different as for the 407; here is always running (?) and the DMA did not work properly anymore.2. I made a testsetup with CubeMX (6.14.1):- I2S Philips- 48 kS- 16 bit- I2S clock = 49,152MHz- no MasterclockI simply use HAL_I2S_Transmit() for a 4 word buffer to send. The buffer is 32bit aligned and is in "normal" ram since DTCMRAM does not work for the DMA (lateron).The function generates proper output for BCK, Data and LRCK, but it never stops. It sends the last word from buffer over and over again. I can switch of i2s, than it stopps. Is this to be expected (?)3. Next approach:- Same configuration as (2), but using DMA, Half-Word(16bit) for per and mem, no fifo- The callback HAL_I2S_TxCpltCallback() is called with the right SP

Hi everyone,I've a strange problem when I write to an external flash memory (S29GL512T) throught a STM32F767 MCU and a custom external loader loaded in the STM32CubeProgrammer.After debugging the external loader several times, I've found that the contents of the buffer that CubeProgrammer gives me for the write operation has partially invalid data. I have done this test in 2 contexts:Using FMC to programm external flash. In this context I have invalid data before programming the external flash. Without using FMC. This context is only for check the content of buffer without FMC interfere and the content matches.So I don't understand why, when you use FMC to program the external flash, the contents of the given buffer are manipulated.This follows shows the original data I want program at address 0x60060000 and the log generated during the programm procedure.

Hello everyone,I want to make a usb connection using USB_OTG_FS_DP and USB_OTG_FS_DM pins on the STM32U575 board. When I tried it with the examples found on the internet, it didn't work. When I tried the same method on the STM32F401 board, it was enough to select only USB_OTG_FS -> Device Only and Middleware -> USB_DEVICE -> virtual com port. What basic settings do I need to make to see my STM32U575 board as a virtual com port on the computer? I'm not very experienced in this. Thank you in advance for your help. Also, when I use the ux_device_cdc_acm example in CubeIDE, it does not appear as a virtual com port.

 Hello everyone, I am using the STM32F042K6 for a small project where I don't have much space. Therefore, I rely on the small package and the "crystal-less USB" function. The hardware arrived today, but unfortunately, I had to realize that the USB library seems to be too large for the chip. I created a new, empty project in CUBE IDE, with only I2C and USB (COM PORT) enabled, and I get the following error message: "c:\st\stm32cubeide_.2.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.200.202301161003\tools\arm-none-eabi\bin\ld.exe: Test_Project.elf section .data' will not fit in region FLASH' c:\st\stm32cubeide_1.2.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.200.202301161003\tools\arm-none-eabi\bin\ld.e
