STM32 MCUs

Hi Community,  I'm a new Developer/ for ST Microcontrollers, Now Im currently using STM32H723ZGT6 (NUCLEO - 144). Im currently working on ethernet (LWIP), the ping is not working for this code that i have generated . I have seen some youtube channels but I cant rectify and make the ping, I have tried all the possible things like , flash linker script , enabling ICache , Dcache , using MPU(Memory Protection Unit), change them to static ip for both board and my PC and So on . I have tried but I dont know whether my code or my implementation is correct or not . Can anybody help me with this ?.. I have attached the file thats my code and how project. pls have a look into that.  Thank You. 

Hello STM32 Community,I am developing a system on the NUCLEO-N657X0-Q using ThreadX and NetX Duo and I am having a hard time to make the ethernet work. I want to implement a web server in my system but I cannot make the Ethernet communicate.Problem:I am unable to receive or transmit any Ethernet frames. The PHY link establishes successfully (from what I see on my linux terminal, autonegotiation completes, Link is UP, and the LEDs on the plug turns on normally), but pinging the Nucleo's static IP yields no response. Wireshark shows no ARP or ICMP packets originating from the Nucleo.Trying to debug, I see that the the MAC/DMA interrupt `ETH1_IRQHandler` is never triggered by incoming network traffic. It fires exactly twice during the initial board boot sequence(where, for what I understand, some DMA errors flag are raised), but remains compl

I am trying to interface STM32L432KCU6 with ADIN1110. Volktek IMC-553 media converter is used to bridge the MCU board with laptop. I am trying to send UDP data. But communication is not succesful. I have a custom project board with the MCU as well as a nucleo board. I tried on both. However I have succesfully interfaced STM32 with ENC28J60 and communicated with laptop over UDP. I am currently doing development in Zephyr. However if any one can support in Arduino/STM32 Cube or any other, I am OK. My intention is succesfully interface ADIN1110 with STM32 and communicate data and visualise in laptop.Thanks in advance.

Split from this thread  My firmware is based on this ccid usbd driver https://github.com/STMicroelectronics/stm32-mw-usb-device/blob/master/Class/CCID/Src/usbd_ccid.c . The issue that I face, the PC finishes receiving data immediately after receiving 256 bytes (10 bytes of header + 246 bytes of data). when I want to send to pc 253 bytes of data + 10 bytes of header (263 bytes in total) by splitting (64 bytes by 64 bytes) the PC finishes receiving data immediately after receiving the fourth chunk which is 256 bytes (10 bytes of header and 243 bytes of data), It doesn't wait for the fifth chunk, which carries the remaining 7 bytes

Hi, is anybody able to confirm if the STM32H563ZIT3Q has an ethernet peripheral? Thanks, regards. 

Hi everyone, I’m building an open-source desktop IDE for microcontroller learning and prototyping, mainly focused on Arduino and STM32. The goal is not to replace professional tools like STM32CubeIDE, PlatformIO, Keil or IAR, but to provide a simpler learning-oriented workflow for students, technicians and training centers. Current / planned features: Arduino and STM32 project creation Build / upload workflow Serial monitor and serial plotter STM32 debug with GDB/OpenOCD Register / memory / stack views Basic SVD peripheral view Static analysis with cppcheck / MISRA-light Coverage reports Crash / HardFault reporting Power profiling demo via UART/SWO-style events QEMU/Renode simulation experiments I’m looking for honest feedback: Would such a tool be useful for education or training? Which feature would be most valuable?

I'm using an STM32H7S78-DK board and I have a part of the firmware that, from the boot, updates the FLASH from a .bin inside an SD cardThe code is pretty simple as I loop the FLASH comparing every sector with the one in the SD card and, if different I erase the internal flash sector and write the new one.Everything was working correctly until a update the code via CubeMXThe read seems to still workingif (EXTMEM_Read(0, fw_offset, flash_buf, br) != 0)but as soon as I do theif (EXTMEM_EraseSector(0, fw_offset, FLASH_SECTOR_SIZE) != 0)I got an errorThe crash happens in if (EXTMEM_DRIVER_NOR_SFDP_OK != EXTMEM_DRIVER_NOR_SFDP_SectorErase(&extmem_list_config[MemId].NorSfdpObject, local_address, sector_type)) { retr = EXTMEM_ERROR_DRIVER; }I've rolled back jus

Hello,long time lurker, now with an issue that I would like to solve. I developed a firmware that runs standalone without issue. I would like to use the secure manager on my STM32H573VI microcontroller.I followed the procedures at this link: https://wiki.st.com/stm32mcu/wiki/Security:How_to_make_your_application_compatible_with_Secure_Manager  and I am able to run the python provisioning.py --sfi-flash command. Then from the cube ide I can debug my program that is written with cmake and the cubemx template.Since I am using threadx I set TIM6 as a time base for the HAL.What I observe is the following...- if I run the application straight away, I do not see the tick increment. - I set an __enable_interrupt() before HAL_Init() and I see that

I've been struggling with a strange ADC problem for a while, and have now made some interesting observations.The scenarioI'm using an STM32G474, where HRTIM directly controls a peltier driver for temperature regulation. Temperatures are measured by ADC4 (12 bit resolution), running in DMA circular mode, triggered by TIM7, at 1 kHz. This works. Temperatures are coming in, and are being used for PID regulation.The problemQuite often – perhaps always – some of the temperature readings are being disturbed, but only at certain temperatures. At first, I thought that it was random noise, but in a graph the noise looks strange. Not random at all.After monitoring the raw ADC values that the DMA has thrown into memory, I discovered something that might be a clue – or it might just be a source of confusion. Every time a noisy sequence occurs, the ADC readout jumps to a lower nearby value where the five least significant bits

Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebuffer. There is no error, but the output is invalid.I can copy to the AXISRAM3 using HPDMA without any issue. I have configured the RISAF4/5/6; otherwise, I am unable to copy to AXISRAM3. This is the code to configure RISAF4/5/6 (NPU RAMs): __HAL_RCC_RISAF_CLK_ENABLE(); RISAF4->REG[0].CFGR = 0x00000000; RISAF4->REG[1].CFGR = 0x00000000; RISAF4->REG[0].CIDCFGR = 0x000F000F; /* RW for everyone */ RISAF4->REG[0].ENDR = 0xFFFFFFFF; /* all-encompassing */ RISAF4->REG[0].CFGR = 0x00000101; /* enabled, secure, unprivileged for everyone */ RISAF4->REG[1].CIDCFGR = 0x00FF00FF; /* RW for everyone */ RISAF4->REG[1].ENDR = 0xFFFFFFFF; /* all-

Hello, I am using a B-G431-ESC1 board to power some BLDC motors. I have alrady used it succesfully to spin some 2 pole pairs BLDC using Hall sensors for speed control. I even managed to implement some code to stop the motor at every half rotation of the shaft. It worked flawlessly with this type of motor. Now, I tried connecting a different type of BLDC, still 2 pole pairs but thats all I know since I don't have the datasheet. The motor profiling part went as expected and it managed to calculate all the relevant properties of the motor. I saved it and implemented the Hall sensors as aux speed control for Hall profiling. The difference from the other type of motor is that this one has a 6-wire Hall connection. Using an oscilloscope, I found that the extra cable was likely for temperature, so I left it unconnected. However, I keep getting Pin not connected on the pin wher the same cable is plugged (the blue cable). Whether I put the blue cable on H1, H2 or H3, the board doesnt recogni

Hi, On STM32F746G-DISCO board I have a problem with USART1 (ST-Link VCP): - TX (PA9) works fine – I can send messages- RX (PB7) doesn't receive any characters and I think the board is not waiting for commands Tested both polling (HAL_UART_Receive) and interrupt mode (HAL_UART_Receive_IT). Pins are configured correctly. Did anyone have similar issue on this board? Any ideas what can block RX?

 Hi,I am working with the OEMiRoT reference project (STM32U385) and I need to configure a single Secure application image without TrustZone isolation (S-only application), while still keeping the Secure Data Image enabled.From flash_layout.h, I see the following:  #define MCUBOOT_APP_IMAGE_NUMBER 1#define FLASH_NS_PARTITION_SIZE (0x32000) /* default case */and also this condition:

We have a custom `STM32WL33CCV6` (`VFQFPN32`) board that should reach about `4 µA` in Deepstop, similar to the NUCLEO-WL33, but instead it drops only to roughly `450–500 µA` and appears to restart on Deepstop entry. `NRST` does not glitch low, and the behavior is unchanged with only `3.3V` and `GND` connected. We also tested direct `HAL_PWR_EnterDEEPSTOPMode()` with wake sources disabled, and it still appears to reboot rather than stay in Deepstop. We reviewed ST errata `ES0612` and applied the documented `VFQFPN32` workaround from section `2.2.9` for nonbonded GPIOs causing increased Run-mode current by forcing the listed nonbonded pins to pulldown at startup. That workaround had no effect on the Deepstop issue. The custom board’s `VFBSD / VLXSD / VDDSD / VDDRF` schematic and BOM appear close to the ST reference, so we are asking whether there are known WL33 low-power / SMPS / Deepstop pitfalls beyond errata `2.2.9` that could explain a persistent `~500 µA` floor or an appar

Hi all,I am trying to develop a bootloader software for STM32F765.I requires two features in it.1) jumping from Bootloader to Application2) jumping from Application to BootloaderI could make jump from Bootloader to Application very easily.But I am suffering with jumping from Application to Bootloader for 4-5 days now.The final code I tried is given below:void Bootloader_JumpToBootloader_Program(void) { void (*app_reset_handler)(void); __disable_irq(); SysTick->CTRL = 0 ; SysTick->LOAD = 0; SysTick->VAL = 0; HAL_RCC_DeInit(); HAL_DeInit(); /* 2) disable all enabled interrupts */ NVIC->ICER[ 0 ] = 0xFFFFFFFF ; NVIC->ICER[ 1 ] = 0xFFFFFFFF ; NVIC->ICER[ 2 ] = 0xFFFFFFFF ; NVIC->ICER[ 3 ] = 0xFFFFFFFF ; NVIC->ICER[ 4 ] = 0xFFFFFFFF ; NVIC->ICER[ 5 ] = 0xFFFFFFFF ; NVIC->ICER[ 6 ] = 0xFFFFFFFF ; NVIC->ICER[ 7 ] = 0xFFFFFFFF ; NVIC->ICPR[ 0 ]

Hi  i have a board with STM32F4 and an EMMC. And I am using FATFS.  I managed to enable the STM32 RTC and added the necessary code in get_fattime(); There is one problem stil: under windows "created" and "modified" date are shown corerctly. But "accessed" date is wrong.  See attached image.  Any clue what is going wrong? Thx  

Dear all,I think I have discovered a bug in the CMSIS headers supplied for the STM32H7RSx and STM32H7x MCUs.In "Drivers/CMSIS/Device/ST/STM32H7RSxx/Include/stm32h7rsxx.h", there are definitions for ATOMIC_SET_BIT() and ATOMIC_CLEAR_BIT() among others, see https://github.com/STMicroelectronics/cmsis-device-h7rs/blob/7e6e213ddc397c76622a0aca2f623ccc3b34c010/Include/stm32h7rsxx.h#L162:/* Use of CMSIS compiler intrinsics for register exclusive access */ /* Atomic 32-bit register access macro to set one or several bits */ #define ATOMIC_SET_BIT(REG, BIT) \ do { \ uint32_t val; \ do { \ val = __LDREXW((__IO uint32_t *)&(REG)) | (BIT); \ } while ((__STREXW(val,(__IO uint32_t *)&(REG))) != 0U); \ } while(0)

I'm writing firmware for a development board based on the STM32H743 MCU, and I want to use an external GPIO input as the trigger or synchronization signal of DMAMUX to initiate DMA transactions. However, it seems that very little information is available on using GPIOs to start DMAs. In the reference manual, "Table 127. DMAMUX2: assignment of trigger inputs to resources" and "Table 128. DMAMUX2: assignment of synchronization inputs to resources", it shows two trigger input signals: "Syscfg_exti0_mux" (number 20), and "Syscfg_exti2_mux" (number 21). So it seems to suggest that the EXTI trigger sources can indeed be used to trigger the DMA, but these two signals are not mentioned anywhere in the entire reference manual, there's no block diagram showing exactly what GPIO pins are connected. It says "SYSCFG" and "MUX", so they're probably the outputs controlled by programming SYSCFG_EXTICR1, SYSCFG_EXTICR2, SYSCFG_EXTICR3, SYSCFG_EXTICR4. But there are 4 EXTICRx and only two

I am currently working with the LoRa-E5 Mini module based on the STM32WLE5JC microcontroller, and I am using STM32CubeIDE version 2.1.0 for development. I have successfully tested basic GPIO functionality (LED blinking), and I am now trying to implement LoRa-based communication (transmission and reception) using the integrated SubGHz radio. However, I am facing challenges in properly configuring and utilizing the SubGHz_Phy middleware and radio drivers within STM32CubeIDE. Specifically, I need guidance on the following: The correct procedure to enable and configure the SubGHz radio peripheral in STM32CubeIDE for STM32WLE5JC. How to properly include and use the SubGHz_Phy middleware for basic LoRa communication. Availability of any official example projects (such as Ping-Pong or Tx/Rx) compatible with STM32CubeIDE 2.1.0 for the LoRa-E5 Mini module. Proper conf
