Hello,My design does not produce interrupts and I'm not sure why.Goal:SPI6 gets a 2MHz clock (external). For each clock the BDMA should take one 1 byte from a buffer (SRAM4, D3) and put it to the MISO. The BDMA runs double buffered => it should cycle M0/M1.void MX_SPI6_Init(void) {   /* USER CODE BEGIN SPI6_Init 0 */   /* USER CODE END SPI6_Init 0 */   /* USER CODE BEGIN SPI6_Init 1 */   /* USER CODE END SPI6_Init 1 */ hspi6.Instance = SPI6; hspi6.Init.Mode = SPI_MODE_SLAVE; hspi6.Init.Direction = SPI_DIRECTION_2LINES; hspi6.Init.DataSize = SPI_DATASIZE_8BIT; hspi6.Init.CLKPolarity = SPI_POLARITY_LOW; hspi6.Init.CLKPhase = SPI_PHASE_1EDGE; hspi6.Init.NSS = SPI_NSS_SOFT; hspi6.Init.FirstBit = SPI_FIRSTBIT_MSB; hspi6.Init.TIMode = SPI_TIMODE_DISABLE; hspi6.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE; hspi6.Init.CRCPolynomial = 0x0; hspi6.Init.NSSPMode = SPI_NSS_PULSE_DISABLE; hspi6.In

My code is larger than expected and I am close to the 32K program boundary of my device. When I optimize for debugging or have no optimize I cannot test new code. When I optimize for size I have plenty of room for the new code, but single stepping through the code to find a bug is a problem because the optimization jumps all over the place. So can I optimize for size the files that I know are good, and optimize for debugging or no optimize the files I am working on? It appears it is optimize by the whole project. If I change the optimization, it recompiles the whole project to that optimization. The new rev of the board increases the memory from 32K to 64K but that is not going to happen for a couple of months, and I need this version working before they will release the new board. (Chicken and Egg problem)

estoy utilizando flash para escribir y leer mientras tengo un bluetooth conectado por serial DMA, cuando intento escribir en flash en la consola de stm32cubeide aparece "Target is not responding, retrying..." mientras que mi serial de dma con el bluetooh sigue comunicando, pero aveces cuando usao otras funciones del bluetooh que tengo que escribir nuevamente en la flash se detiene todo. estoy desabilitando interrupciones antes de grabar y ayuda un poco, pero quiero pasar las funciones para RAM como dice algunas informaciones. solo que no tengo idea de como se hace, donde onsigo el enlazador? que informacion necesito para modificar el enlazador? que informacion necesito para modificar RAMfunc? estoy usando un stm32f030k6t6, ya lei la nota de aplicacion para escribir en flash sin interrupcion, pero no se ocmo modificar el enlazador ni como hacer RAMfunc. agradezco una sugerencia

hi well i asked before about the nrst pin herehttps://community.st.com/s/feed/0D53W00001bm2gtSAAstill no success but i'm trying to debug another board and it jump here

I am using STM32G070RBTX micro configured for ADC with DMA. My project works well configured with CubeIDE version 1.8.0. However after I updated to 1.9.0, the ADC Continuous Conversion Mode cannot be Enabled from CubeMX. It force to use Discontinuous mode, which cannot be Disabled!Please see the attached picture.

Dear @Khouloud ZEMMELI​ Please review my below request. The STM32CubeMX generated code does not mark functions present with the Interrupt Related C file as __weak.https://github.com/STMicroelectronics/STM32CubeH7/issues/175Please help fix the issue.Thanks,Rajeev

When I am in the EDITION mode in the CUBE IDE, I perceived that the TARGET is running the last downloaded program. In my TARGET it jeopardize several parts like EEPROM model (which I just made). Therefore, I would like to ask if someone know how to STOP my TARGET (RESETING) as soon as we enter the CUBE's EDITION mode? Regards.

I have mapped inputs to multiple channels of ADC1 and ADC2 in the pinout of my STM32F103RCTx MCU with CubeMX. However, while I am able to configure DMA for ADC1, the "DMA settings" tab for ADC2 does not appear when I open the ADC2 configuration in CubeMX. Is DMA unavailable for ADC2 in this MCU? Or is there a way to enable it? I could not find any mention of this in the datasheet, so any help would be appreciated.

Hello, I would like to open an existing project : But when I select .'project' I have this picture and I can't see the code : Do you know how to do ? Thank you for your helps Regards

Hi,I have written a STM32H747 external loader for a NAND Flash on the FMC bus of the CM7. The test software of the loader functions (Init, MassErase, SectorErase, ...) works perfectly. The functions are called correctly by the STM32CubeProgrammer. As a test of the functions, I forward the parameters of the function calls and the results to a UART and can thus debug the "internal" processes. The initialization and erase works perfectly. When programming a page there is now an unsolvable problem. The functionint Write( uint32_t Address, uint32_t Size, uint8_t *buffer ) gets values for Size that are much too large. The hex file to be programmed is about 303kB. The 303kB are divided into only two programming cycles:1. Page programming address: 0x80000800 size: 0x0002502C 2. Page Programming Address: 0x8002582C Size: 0x00025000Why is the size 0x0002502C or 0x00025000 and not 0x800 as defined?The ext. NAND Flash

Hello dear friends,I have installed STM32CUBEIDE v1.7, v1.8 and v1.9. Since V1.8 the indexer can't find variables and functions in cube-generated files and throw this type of message."Could not find symbol 'blah blah' in index".This issue is really annoying. Could you help me on solving this issue?PS. V1.7 indexer is working.

Hello All,I have updated to CubeMX 6.5 and STM32F4 1.27 and now thinks are failing in my project.I could reproduce this using NucleoF429 board.When I create example from example selector LwIP_HTTP_Server_Netconn_RTOSit activates ethernetI can ping the boardwhen I create example from the board selector nucleo429 and preset all peripherals to default it failsI add LwIPassign BSP driver LAN8742TCP protocols are workingICMP ping results in timeout on PCMy investigation shows:a ping response is sentthe ping response has ICMP CRC set to 0(zero) and fails CRC check on pCeven I manually set ICMP CRC before sending via HAL driver, the driver modifies this CRC to 0(zero) ??????also: I have to comment some stupid regression errors in the lwipopts.h/*----- Default Value for H7 devices: 0x30044000 -----*

The "Convert to C++" seems to have vanished of the properties popup in STM32CubeIDE 1.90, so how do I enable C++ for a project now?Paul

After install node-red-contrib-line-messaging-api.I closed STM32CubeMonitor and open it again.It appears an error dialog box as attached picture.I tried to uninstall it and then install it again.It still fails.

Hello all, I want to interface my STM32f407vgtx microcontroller with ILI9325 lcd and for this I have initialized FSMC as per my requirements. But to properly communicate with ILI9325 LCD , I want to read/write pins named NOE, NWE, CS , Cmd/Data .Can we have some APIs available to do this. Please help.

The STM32 Cube Programmer lets me read memory, but the address is required. It is not clear *where* the DFU loader puts a .hex file. What I want is to recover the hex file.

I am using the example project GPIO_IOToggle_TrustZone for NUCLEO-U575ZI-Q and added Timer3 for Non-secure application via CubeMx with Interrupts enabled. When this Timer is started with HAL_TIM_Base_Start_IT the application runs into SecureFault_Handler. Something seems to be not correctly configured by CubeMx.

Hello There,I'm working on IAP app and need to relocate vector table and came across NVIC_SetVectorTable().But I'm not able to find this API. I'm using CubeIDE and did generate the initial code with inbuilt cube mx. Any help is appreciated.Regards,Keshav Aggarwal

I am currently working on a project that would require me to access a STM32 microcontroller from Simulink. I am going to be using the STM32L476RG momentarily and STM32F722ZE in the future. I have tried using the STM32-Mat file, but it doesn't allow me to run the code through Simulink in real-time. I have tried using the L476RG board with the STM32 Embedded Code Support, but there are no options to add a configuration file from CubeMX. Are there any ways to do so? Thank you.

I'm try to read acceleration from KX132 accelerometer with a STM32F446ZE through I2C with DMA. I create a project with STMCubeMX and enable DMA and interruptions.The accelerometer has six register each one of 1 byte where save acceleration in this format: XOUT_L,XOUT_H, YOUT_L, YOUT_H, ZOUT_L, ZOUT_H.​I want to read this registers continously with I2C DMA but I have a problem, only can read once time and never jump the complete transfer interruption again. I'll leave parts of my code so you can understand what i'm doing.​This configuration it was create by STMCubeMX. I choose DMA_CIRCULAR mode to repeat reading by DMA but doesn't work.​i2c.c/* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include "i2c.h"   /* USER CODE BEGIN 0 */   /* USER CODE END 0 */   I2C_HandleTypeDef hi2c2; DMA_HandleTypeDef hdma_i2c2_rx; DMA_HandleTypeDef hdma_i2c2_tx; &nb
