STM32 MCUs Embedded software

Hello,I'm encountering a problem with the STM32G0B0 (also applicable to the STM32G0B1RE) when using flash memory in single bank mode.My application requires single bank mode, but when I use the erase function to erase pages (from both bank 1 and bank 2), it erases the wrong page.using the "FLASH_EraseProgram" example provided on the STM32CubeFw with the updates below:Define bank 2 user pages address in main.h #define ADDR_FLASH_PAGE_128 ((uint32_t)0x08040000) /* Base @ of Page 128, 2 Kbytes */ #define ADDR_FLASH_PAGE_129 ((uint32_t)0x08040800) /* Base @ of Page 129, 2 Kbytes */ #define ADDR_FLASH_PAGE_130 ((uint32_t)0x08041000) /* Base @ of Page 130, 2 Kbytes */ #define ADDR_FLASH_PAGE_131 ((uint32_t)0x08041800) /* Base @ of Page 131, 2 Kbytes */ Update "FLASH_USER_START_ADDR" and "FLASH_USER_END_ADDR" #define FLASH_USER_START_ADDR ADDR_FLASH_PAGE_126 /* Start @ of user Flash area */ #define FLASH_USER_END_ADDR (ADDR_FLASH_PAGE_131 + FLASH_PAGE_SIZE - 1) /* End @ of user

Hello everybody. I'm trying to make LWIP work on NUCLEO-H723ZG board, but I can't even get a ping response so far, even with static (DHCP disabled) network configuration. The project uses FreeRTOS (CMSIS API v2) and is created with MX tool. It seems to be an ARP problem, since there is no ICMP request from my PC when I execute the ping command (checked with Wireshark). Did anyone face similar issues using an environment like this? Attached is the output generated by LWIP, as well as the project configuration file and linker script.  Any help will be greatly appreciated. Thank you!

Hi,I’m working with a custom PCB based on an STM32H743BI and an external MT25TL01G memory device.To manage the data I’m using FileX + LevelX. I’m able to create the media, create directories, create files, write to them, and read them without issues. However, I’m running into a problem when trying to read files after a reset.After formatting the media with:fx_media_format(&pFileManagerDesc->fxFileMedia, fx_stm32_levelx_nor_driver, (VOID *)LX_NOR_QSPI_DRIVER_ID, (UCHAR *) mediaBuffer, sizeof(mediaBuffer), QSPI_VOLUME_NAME, QSPI_NUMBER_OF_FATS, 32, QSPI_HIDDEN_SECTORS, ((LX_STM32_QSPI_FLASH_SIZE - LX_STM32_QSPI_SECTOR_SIZE) / QSPI_SECTOR_SIZE), QSPI_SECTOR_SIZE, 8, 1, 1); I open the media and try to read from it, but I always the error FX_NO_FOUND trying to open the file.This doesn’t happen if I create a file first. I’m not sure if I’m missing a step before reading the media after formatting.I’m not performing any erase operation because I have: LX_S

Hi!I’m asking for your recommendations :I would like to integrate the DCMIPP continuous example to add a photo capture and recording feature to the SD card through a button.I have already configured the SD card using CubeMX, and now I want to integrate the DCMIPP continuous example and then continue adding my own contributions.Is there another example that would be more appropriate to use as a base?Because I prefer to use CubeMX, but with the DCMIPP example I find myself having to manually add all the libraries to my project < as it comes without cubemx>, and at the moment I see that some libraries are not recognized despite that I added them with all the paths.Do you have any suggestions for what I want to do?Thanks in advance

Hi,on STM32F429I-DISC the timer TIM2 kicks ADC1 and the data goes to buffer via DMA. APB1 clock for TIM2 is 36MHz, reload value for TIM2 is 143, I exspect 36e6/144= 250k samples/second.I get 8.3e6 samples in 123 seconds which results in 67.4ks/s. This is factor 3.7 low, not even an integer ratio.There is a clock issue for the 48MHz, see enclosed .ioc What do I miss?THX CheersDetlef  

 Hello, I have a Nucleo-H723ZG that I am trying to setup a Continuous running ADC that fills a buffer VIA DMA. I have read tutorials, watched videos, looked at the data sheets and still can't get it working.Tools:  CubeMX to generate code   VScode to compile and debug code Hardware:    NUCLEO-H723ZGGoal:  I am trying to have the ADC Continuously trigger and fill the DMA buffer overwriting the old values. I'm not attempting to trigger from a timer or any external means. I just want to start the ADC and it be free running. Then I'll handle the data in the buffer else where. Currently:  I can't get anything to happen. The ADC works fine if I set it up for polling and I get correct ADC values. If I set it up for DMA continuous the buffer never gets any values and the ISR HAL_ADC_ConvCpltCallback() never fires. (I used a debug break point inside the isr) Update: I found that if I check the ADC_HandleTypeDef hadc1 while de

Searching through the forum it seems like there are tens of posts regarding this topic. I read many of them, but I struggle to find a solution that applies to me.First of, I use an STM32H743VIT.My goal: Use ADC1 and ADC2, one channel each. The two ADCs should be tied together. The whole conversion should be triggered by TIM4 update event and the data should be moved via DMA.What works: If I just use TIM4 and two DMA streams that move the data for each ADC individually, it works. As soon as I try to use the dual mode, it does nothing.When I'm in dual mode I have confirmed that the timer is still running. TIM4->CNT is changing. I've spent almost two hours with the debugger in the SFR and checked the registers. I'm not sure if I'm close to the issue, but there is something that seems suspicious based on the research I did: DMA1->S0NDTR->NDT does not change, indicating that the DMA stream does nothing. However ADC1->CR->ADSTART is at 0x1, indicating that it tries to do somet

Hello,I implemented the How to use SNTP over LwIP and RTC with an STM32 - STMicroelectronics Community example (not using FreeTOS) in the suggested STM32H723ZG NUCLEO-144 board. The app runs, but when it tries to allocate memory for DHCP with the mem_memalloc() function in dhcp:start (dhc.c lib file) it always returns null pointer. I t can't allocate memory for DHCP structure, the dhcp pointer is always 0 and dhcp_start() always returns with ERR_MEM error.dhcp_start(struct netif *netif) { struct dhcp *dhcp; ... /* no DHCP client attached yet? */ if (dhcp == NULL) { dhcp = (struct dhcp *)mem_malloc(sizeof(struct dhcp)); if (dhcp == NULL) { return ERR_MEM; } ... }In STM32H723ZGTX_FLASH.ld I have:MEMORY { ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 320K RAM_D2 (xrw) : ORIG

I am new to ThreadX. I have had experience with FreeRTOS generated with CubeMX.However, I have been starting over repeatedly with CubeMX. Just trying to create a base project with Nucleo-F767Zi.I need to find some documentation for starting this process. I am missing something.Thanks,Greg

Hi, I'm using STM32F407 TIM1 channel 1 to measure the frequency of a square wave. The result is not accurate. For example, when input frequency is 1000.0Hz, the result is around 1006Hz. Input frequency has been verified by an oscilloscope, with probe attaching directly to STM32 pin. My ioc configuration:1. APB2 peripheral clock frequency is 42MHz, APB2 timer clock frequency is 84MHz. (in the datasheet, TIM1 connects to APB2)2. Pin PE9 is configured as TIM1_CH13. TIM1_CH1 uses Input Capture Direct mode4. Prescaler=1 (so TIM1 frequency=84/(1+1)=42MHz)5. Counter mode is Up, Counter Period is 65535. auto-reload preload is Enable6. A DMA connects to TIM1. DMA Request is TIM1_CH1 to capture TIM1->CCR1's value My code:#include "main.h" #include <assert.h> #include <stdint.h> #include <stdlib.h> TIM_HandleTypeDef htim1; DMA_HandleTypeDef hdma_tim1_ch1; #define ARRAY_LEN(a) (sizeof(a) / sizeof(a[0])) #define TIM_FREQ 42000000 // TIM1 frequency is 42MHz // g_timD

Hello, i just wanna take a snapshot by STM32N6570-DK with IMX335. I am using SnapshotDecimation as my reference. after reviewing the code. i wonder why AXI RAM3/4 and RIF are necessary for this project i saw it in 'HAL_DCMIPP_MspInit' function, but i didnt found anything about AXI RAM in other parts of the code.anyone can explain why does axiram necessary for this project?void HAL_DCMIPP_MspInit(DCMIPP_HandleTypeDef* hdcmipp) { RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0}; RAMCFG_HandleTypeDef hramcfg = {0}; RIMC_MasterConfig_t RIMC_master = {0}; if(hdcmipp->Instance==DCMIPP) { /* USER CODE BEGIN DCMIPP_MspInit 0 */ /*** Enable peripheral clock ***/ /* Enable DCMIPP clock */ __HAL_RCC_DCMIPP_CLK_ENABLE(); __HAL_RCC_DCMIPP_FORCE_RESET(); __HAL_RCC_DCMIPP_RELEASE_RESET(); /*** Configure the NVIC for DCMIPP ***/ /* NVIC configuration for DCMIPP transfer complete interrupt */ HAL_NVIC_SetPriority(DCMIPP_IRQn, 0x07, 0); HAL_NVIC_EnableIRQ(DCMIPP_IRQn

 My question revolves around TouchGFX and firmware for accessing the SD card.I'm studying the STM32N657-DK and am already getting good results with TouchGFX. Now I need to write a module to read the SD card, count the files, and update a progress bar. I already know how to update it, but I'm still having difficulties reading the SD card. I don't know which library to use.Could you suggest examples and/or which library would be most suitable?Thank you.

Cannot build a very basic task i.e. blinking in built LED in STM32N657X0-Q Nucleo Board.Please provide me the complete and step step procedure atleast how it happened and why.Lots of issue and confusion occurs in this Board I don't know why but it occurs

Hai Everyone, I am currently working with the STM32H723ZGT6 Nucleo board to implement basic SD card read and write functionality.I have enabled RCC, configured HSE and PLL, and set the system clock to 240 MHz. The SDMMC kernel clock is sourced from PLL1Q at 48 MHz.I tested the SD interface in both 1-bit mode and 4-bit wide bus mode. While the write operation is working correctly, I am unable to read data from the SD card. I would appreciate it if someone could help me resolve this issue. Your support would be very helpful.   Thankyou.   Best Regards, Aashritha

The current state of the CherryUSB is no stm32h5 is listed.  Does anyone know if the IP is close enough to dwc2 to be portable? My needs are cdc-ecm host, and I'm looking at options.  Device is stm32h563, using FreeRTOS and not going to do threadx 1. Port CherryUSB 2. Use legacy USB Host stack, copy and tweak cdc-acm3. Use tinyusb, tweak cdc-acm4. Use USBX and fight threadx port layer. (The ECM Layer uses threads as far as I can tell, so not trivial)

Hi, I use the stm32f103 to read the IMU(BNO055) via I2C to get the Quaternion data, I use this library from ivyknob, https://github.com/ivyknob/bno055_stm32 The AR Anchors result is well (Head Mount Display application), I use the USB VCP to Transmit the BNO055 Quaternion data to PC or SBC, using the function CDC_Transmit_FS. But I face a problem immediately, the transmit speed is 100Hz, it will caused the USB_BUSY(race condition), I try some methods, such as add delay in the while loop, using timer interrupt and flag to limit the transmit speed, avoid using sprintf function, it could not solve this problem. As the picture shown below, Tx could write the data from STM32 to PC, but Rx could not write the data from PC to STM32 Files include the main.c and usbd_cdc_if.cCould you give me some advices to resolve this problem.   Thank you Best Regard Steve  

Hello,I am working on a USB Audio streaming project using an STM32F407 Discovery board. I am using the USB Device (Audio Class) and I2S3 to output audio to the onboard CS43L22 DAC (I plan to move to MAX98357 later).Problem:The PC recognizes the board as an "STM32 Audio Class" device. However, when I play audio, there is a very high level of noise/distortion. While I can faintly hear the music behind the noise, the output is dominated by a harsh "buzzing" or "crackling" sound. Any guidance or suggestions would be greatly appreciated!I2S Parameter SettingsClock configuration 

Split from the Implementing a LwIP and FreeRTOS™ v1 UDP echo server on the STM32F7 series Tutorial;Moved to the forum for better visibility & discussion.@mƎALLEm Hi Sir,I am using the same code that works correctly on the development board. However, when I run the same firmware on the custom board, I am encountering an error.Is there any issue in the schematic related to Ethernet?Can I use the same libraries that are used in the Nucleo-H755ZI-Q board for this LAN?If I use the same library and it gets stuck at netif_add() what could be the issue?

Hi all! What event is generated if the MCU receives a data packet equal to the buffer value passed to the HAL_UARTEx_ReceiveToIdle_IT (or HAL_UARTEx_ReceiveToIdle_DMA) function? There will essentially be two events: HAL_UART_RXEVENT_TC and HAL_UART_RXEVENT_IDLE . But which of them will be available in the HAL_UARTEx_RxEventCallback ?

From what i've seen the Rust programming language is becoming more and more popular and since it does not rely on a virtual machine, like java or python, it could be a good option for embedded development and other low-level programs. I know that there are ways to get Rust on STM32 MCUs running, but without official support its really hard to start a series project using those tools. At this point i see it as something fun to try out and benchmark and compare with a traditional C program + FreeRTOS.Does anyone know if there are any official plans from ST to have a Rust wrapper on the existing C HAL or a complete ground-up Rust HAL? Maybe support in CubeIDE for both C and Rust?

Hello,I'm on a custom H75x board and I want to implement a stack (+ RTOS heap) overflow detection using the MPU.I placed stack, heap and RTOS heap into DTCM like this:; ____________________ __ 0x20000000 ; | | ; | ^ | -> 0x4000 = 16KB ; | C-Stack / \ | ; | | | ; |_______________|____| __ 0x20004000 ; | | | ; | | | ; | \ / C-Heap | -> 0x10000 = 64KB ; | v | ; |____________________| __ 0x20014000 ; | | | ; | | | ; | RTOS-Heap \ / | -> 0xC000 = 48kB ; | v | ; |____________________| __ 0x20020000I intend to supervise memory access above and below the DTCM memory via MPU.For stack overflow test, I call a function which allocates an array in the stack with size > stacksize, e.g.static void fTest(uint32_t len) { int8_t abFill[len]; abFill[0] = (uint8_t)0xCD; abFill[len-1] = (uint8_t)0xAB; : }If I step-debug thru these lines I can see that the SP is outside of stack memory and the array write ends up in a bus fault. If I configure the MPU then the mem fault handler is fired. Se
