I ran system bootloader, I can perform the bootloader process using the STM32CubeProgrammer software via USART. But what I want is to run the bootloader software over TCP or UDP using the USART protocol. Because my UART2 line is connected to a TCP converter.I wrote a piece of code using Python, but it's very slow and disconnects after a while. Is it possible to enable STM32CubeProgrammer to communicate with UART protocol over TCP?Softwareally, I used TCP to Uart converters, but STM32CubeRogrammer is getting a time delay error.My system is as follows;

Hier ist die englische Übersetzung deines Textes: --- Hello everyone, I am quite new to the STM family. I am currently working on a project where I need to send data to and read data from an NFC tag using an NFC reader (NFC07A1). This data should then be sent via Bluetooth to another microcontroller and output there via USART. I have already familiarized myself with data input and output via USART. However, I first tried to read the UID of a tag. A UID is always displayed without using a tag. It turned out that it is the UID of the NFC07A1 because I read the UID of the reader using an Android app (just mirrored). As soon as I use my phone as a tag and hold it to the reader, an error message appears. Any other tag I have tried is not even recognized. Only the phone, but it is not readable. This is the code to read the UID:```cvoid MX_NFC7_ReadUID(void){  char uid_str[50]; // Buffer to hold the formatted UID string   // Check if the NFC reader is

i have compiled opus lib on H5. but i can not decode data. this is my init function and works fine.   DecConfigOpus.channels = 2; DecConfigOpus.ms_frame = 20; DecConfigOpus.sample_freq = 48000; uint32_t dec_size = DEC_Opus_getMemorySize(&DecConfigOpus); DecConfigOpus.pInternalMemory = (uint8_t *)malloc(dec_size); int opus_err; if (DEC_Opus_Init(&DecConfigOpus, &opus_err) != OPUS_SUCCESS) { printf("ERROR! DEC_Opus_Init()\r\n"); break; } and in decode function first time return 960 and then -4. int packetSize = 80; // Adjust based on your actual packet size for (int i = 0; i < sizeof(music); i += packetSize) { int x = DEC_Opus_Decode((uint8_t*)&music[i], packetSize, DecConfigOpus.pInternalMemory); if (x < 0) { printf("Error decoding packet at index %d: %d\n", i, x); break; // Exit the loop or handle error as appropriate } else { printf("Decoded packet at index %d, x = %d\n", i, x); } }  

Hi, I am using MCU : STM32H743ZGT6.When I write the code and build it, I get these errors. So even if I create a new project and build without writing any code, I get the same error.  How do I fix this? Error : c:\st\stm32cubeide_1.10.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\ld.exe:C:\Users\giwon30\Desktop\giwon\testest\STM32H743ZGTX_FLASH.ld:92: non constant or forward reference address expression for section .ARM.extabcollect2.exe: error: ld returned 1 exit statusmake: *** [makefile:64: testest.elf] Error 1"make -j4 all" terminated with exit code 2.

I have a BMA5 accelerometer sensor and I want to change its I2C address. I have enabled I2C1 in cubemx and set pull-up for SDA and SCK lines. I need guidance on the program algorithm and cubemx setting for this task as I am new to this field. Also, I would like to know, do I have to initialize the I2C1_init() again after setting the new address. Thank you.

Using the Nucleo L412KC as a template, I fabbed a tiny test board to see if I could make my own kit.It is extremely basic, but when I connect the 3V3, GND, NRST, SWDIO, SWDCLK, none of the reset modes in the IDE result in the STLINK detecting the chip: Starting server with the following options:Persistent Mode : DisabledLogging Level : 1Listen Port Number : 61234Status Refresh Delay : 15sVerbose Mode : DisabledSWD Debug : Enabled Target no device found Error in initializing ST-LINK device.Reason: No device found on target. Here is the schematic: See, extremely basic!Here is the layout:I'm using a V2 (not a V2 ISOL).

Hello everyone,I used Nucleo-F767ZI board for my vehicle robot. I just securely attach the board to the robot and then testing my robot move on different terrains.After this test, I can not connect ST-Link (fail.txt file appeared) and my board did not operate anymore. I tried to press RESET button or upgrade ST-Link firmware, reconnect USB cable or even reset my computer but nothing worked.I believe this board dead. My question: Does ST have documents on shock protection or anti-vibration standards for the Nucleo board?Do I need to install an additional damping system for the board? 

Hello I m trying to figure out how to configure the  CCR bit field in I2C_CCR register in STM32F407 in the reference manual RM0090 it says check the datasheet for the definitions of "tr(SCL) + tw(SCLH)." but I couldn't find them on the datasheet. On the section of I2C characteristics there only I2C analog filter characteristics. Can anyone help?

Hello,I am use a winbond W25Q128JV chip which is connected to the OCTOSPI interface of my STM32H563. I read/write the flash in direct mode. The transfers are done with DMA. Everything works fine as long as the address is smaller than 0x200000 (2 MByte). As soon as I cross that border the DMA stops with HAL_XSPI_FLAG_TE. Has anyone an idea what I am doing wrong?This is how I parametrize the transfer:  (void)memset(&eCmdType, 0x00, sizeof(eCmdType)); eCmdType.Instruction = 0x0B; /* Fast read data */ eCmdType.InstructionMode = HAL_XSPI_INSTRUCTION_1_LINE; eCmdType.InstructionWidth = HAL_XSPI_INSTRUCTION_8_BITS; eCmdType.InstructionDTRMode = HAL_XSPI_INSTRUCTION_DTR_DISABLE; eCmdType.AddressMode = HAL_XSPI_ADDRESS_1_LINE; eCmdType.AddressWidth = HAL_XSPI_ADDRESS_24_BITS; eCmdType.Address = _iStartAddress; eCmdType.DataMode = HAL_XSPI_DATA_1_LINE; eCmdType.DataDTRMode = HAL_XSPI_DATA_DTR_DISABLE; eCmdType.DataLength = _iSize; eCmdType.AlternateBytesMode = HAL_XSPI_ALT_B

Hey,  I am using a STM32F7676vit6 Controller an try to set up a SAI connection to my audio CODEC now my problem is that the CODEC has two Serial outputs and one serial input. So i configured:SAI1A to be the transmitting master SAI1B is a synchronous Slave which is configured to be in sync with SAI1A. SAI2B is also configured a synchronous Slave and configured to be in sync with SAI1A. I also use DMA on all three channels. Now i receive data on SAI1B and but not on SAI2B (SAI1A works fine). Only wired thing is that after txCpltCallback the SCK and FS do not stop....I really don't know what to try anymore please help ;). I use CubeIDE my sai.c file looks like:/* Includes ------------------------------------------------------------------*/ #include "sai.h"   #include "gpio.h" #include "dma.h"   /* USER CODE BEGIN 0 */   /* USER CODE END 0 */   SAI_HandleTypeDef hsai_BlockA1; SAI_HandleTypeDef hsai_BlockB1; SAI_HandleTypeDef hsai_BlockB2; DMA_Ha

Hello,I tried to execute the demo for the STM32G474E EVAL1 explained in this document : STM32CubeG4 STM32G474E-EVAL demonstration firmware - User manual.But, I have an error when the board tries to display the pictures which are on the SD card.I got " Error popup resource file missing please update sd card content".I checked the SD card and my files are well in the right directory.I tried with two different SD cards and I have the same issue.When I checked with the debugger, I have the impression that is a problem during the initialization of the SD card during the call of SD_GoIdleState()But now I have no idea to go further in my investigation.So I search some help to solve my issue

Hello, I would like to know if anyone has already encountered this problem. I have an LPTIMER configured with an ARR Match interrupt at 100ms I also want to enter my interrupt every 10ms so I added an interrupt in compare mode at 10ms.I have 2 questions: - When I enter my interrupt I test the interrupt that was called but both are permanently TRUE, is it possible to use the COMPARE mode interrupt with the ARR Match interrupt?- The register allowing to clear the interrupts does not seem to work in my case, because before exiting I clear all possible interruptions through the LPTIM1->ICR register but the ISR register is still equals to 1 for all of my interrupts...  Do we have to wait several instructions before I check it ?**INIT LPTimer    //--- Demarrage LSI (oscillateur interne RC 37kHz)--- RCC->CSR |= RCC_CSR_LSION; //--- Selection LSI pour LPTIM --- RCC->CCIPR |= RCC_CCIPR_LPTIM1SEL_0; //--- Validation clock LPTIM --- RCC->APB1ENR |= RCC_

Hello,For my project I am working on two nucleo board H743ZI2.Unfortunately, during an experimentation one of the boards ceased working (LD4 and LD6 red). Maybe a short circuit, I don't know.Anyway I tried to purchase a new NUCLEO-H743ZI2 but it seems the production has stopped, some websites suggest H753ZI.I cannot see anywhere a page which explains the difference bewteen those two models.The page NUCLEO-H753ZI - STM32 Nucleo-144 development board with STM32H753ZI MCU, supports Arduino, ST Zio and morpho connectivity - STMicroelectronics seems to show the same features.One datasheet shows this: NUCLEO-H743ZI2Ethernet• USB OTG FS on Micro-AB connector• STLINK-V3E• LQFP144 NUCLEO-H753ZIEthernet• USB OTG FS on Micro-AB connector• STLINK-V3E• Cryptography• LQFP144 Question 1:Is there a page that lists all the difference between  NUCLEO-H743ZI2 and NUCLEO-H753ZI ?Is there something else than the cryptography ? Question 2:Is it possible to use th

I hope this email finds you well. My name is Nesrine AYED, and I am a student and i'm currently working on my final year project, which involves the development of a 100W USB Power Delivery (PD) adapter. In my research, I came across the EVLVIPGAN100PD reference design from STMicroelectronics, and I am interested in obtaining further information to aid in my project development.I would like to inquire about the following aspects of the reference design:Output Voltage Flexibility:Could you please clarify whether the EVLVIPGAN100PD evaluation board is capable of delivering different output voltages based on the device connected, or does it provide a fixed voltage output?Communication Protocol:I am curious to know how the VIPERGAN100 and the USB PD controller STUSB4761 communicate with each other within the reference design. Specifically, I am interested in understanding if there is a communication protocol utilized (e.g., I2C, SPI) for this purpose.Connector Functions:Upon reviewing the
