Solved

I have an existing stm32f439vitx custom board project which works fine when flashed at address 0x08000000 which I now need to make runnable from an existing bootloader expecting the program to have been flashed at address 0x8008000. Is it enough to change the linker script ROM origin and length?

I use STM32F091VI use LSI for RTC clock.I know that LSI is inaccurate.I set the RTC interrupt to 1 second.However, the interrupt interval was 860ms.Can anyone tell me how to calibrate the RTC?I am happy with the sample source code.

Hi,I am a new developer of stm32h750dk and not familiar with IAR.OS:Windows 10IDE:IAR 8.42.2Tools:ST-link V3 on stm32h750dk board.I generate stm32h750dk online application on touchGFX designer 4.12.3.​I know the flash on chip is designed for bootloader, and the code stored in QSPI Flash.I know how to download the online application hex file to stm32h750dk on stm32Cube Programmer.I do not know how to download and debug the source code to the QSPI Flash via IAR.I want to know if any instructions for download and debug the source code in QSPI Flash via IAR.The settings of the IAR below.It compiles ok, but download failed, it show me that.Thanks for your attention.

I started a new project, and my security requirement states that user authentication is required when updating firmware.I wonder if there's a feature for this, and if not, can the bootload side be modified to meet this requirement?I searched and found a concept like SFU. The chip used is stm32l0x2.

Hi all,I have a STM32H743 running at 400MHz with simple USB 1 wiring to an USB A jack. It works fine, no issues, runs for hours with thousands of read and write operations.But there is one little issue that drives me crazy:If I plug in and unplug one specific USB Stick (Intenso 8GB) sometimes after removing the stick (no read/write ongoing!), I see "USB Device disconnected" in the log (which is perfectly correct when unplugging an USB stick) but just a millsecond later, I get also "USB Device Connected" again - even though there is nothing connected to the port! After this occures, there is nothing more happening in the USB subsystem. Reconnecting any other stick does not change anything - untill a reset of the STM32, there are no more reactions, no events, no USB (dis)connect anymore.This only happens from time to time and only with some sticks. With the SanDisk 64GB "Ultra Flair" for example, I never experienced this issue. At first, to me this looked like some hardware bounce effect

i'm working with spc570s and using gnu free gccc in spc5studio.In my program I need to apply __attribute__(( aligned(32))) to an const struct variable.I tried like this but it does't work.for example.typedef struct{uint32_t aa;uint 32_ bb;...}Astatic const A ***[2]  __attribute__(( aligned(32))) i want to allocate *** with starting address 0xdddddd00(20,40, 60).Thank you in advance.

Hello,I am total new to this field and need your help please. I have an application in which I measure data and collect in a matrix on ram. after the measurement is finished, I write the data on SD card and USART. I had a code that worked perfectly on STM32F407. But I now have to use STM32H7. I have configured the H7 SDMMC like the SDIO and also the FATFS the same as the config on STM32F4. However, the writing on the SD card stops after one time of writing, meaning that data can only be written once on the SD card. I am attaching the sd card function and my STMCubeMX settings here for your view. Any help would be greatly appreciated. void writeToSd8Ch() { free(SDFatFs); retSD = FATFS_LinkDriver(&SD_Driver, SDPath); SDFatFs = malloc(sizeof (FATFS)); res = f_mount(SDFatFs, "", 0); //changed way of the function if (res == FR_OK){ // Append a line for (int i = 0; (i < totalNoOfMeasurements) ; ++i) { res = open_append(&myFile, "oil_sensor_01.txt"); f_sync(&myFi

YStm32f042f6 tssop package , when i am powering, microcontroller is not starting ,even if i use hard reset . its only starting when i connect ST link( SW Debug)  mode.I am using external clock 8 mhz.I have attached Circuit diagram !! i tried with couple of MC but still same problem..

I've got an issue with the CubeIDE from STM (Version 1.1.0). I generated a Cube project, worked with it for 2 months, edited it,... no major problems. But suddenly the IDE deletes files like my main.cpp,.. I just did some adjustments, like adding another AD-Channel and generated the .ioc file with the MX-Editor in the CubeIDE.Luckly I've got a backup on Bitbucket but I cannot work on ths project because I really need the adjustments I've done.Is this a bug or am I too stupid to do some adjustments without deleting needed files?Has anybody this problem too? Or a solution? I would be really thankful.

Hi,I would like to announce measurement results also by text and change the text color based on the results. Green text for a pass, red for failure. How could I do this?

Hi,I have a few views. On each view there is a container (date, time) which has to be updated periodically (every minute) with the new date/time. This container is the same on every view.My idea is to go through the model with the modelListener. But this means that I have to implement the presenter method on every screen...Is there a better way to do this? So that I have only one method in the container?Thank for your help,Cheers, /jimmii

Hello,I read the input data over SPI DMA, but when I added the AI part ICache and DCache are enabled.The problem is that when ICache and DCache are enabled, the SPI DMA is not working.How can I overcome this problem?

I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller.I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC.The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. This make me think that the DMA/MDMA/CPU-loop is not the limiting factor.At a 480MHz FMC clock, the transfer happens at just 1.6MHz, giving me only 20fps on a 16-bit colour 320x240 LCD.At a 240MHz FMC clock, the transfer happens at just 0.8MHz, and so on at slower speeds.I've also tried reducing the various setup and hold times to 1 and 0 cycles, but this has (surprisingly) not affected the waveform on the 8080-bus.My (Cube-MX generated) FMC initialisation code is:  /* FMC initialization function */ static void MX_FMC_Init(void) {   /* USER CODE BEGIN FMC_Init 0 */   /* USER CODE END FMC_Init 0 */   FMC_NORSRAM_TimingTypeDef Timing = {0}; FMC_NORSRAM_TimingTypeDef ExtTiming = {0};   /* USER CODE BEGIN FMC_Init

Posted on August 16, 2012 at 21:45I came across the following problem: I have a free-running timer, and a signal being input on its TIMx_CH1 pin. I want to capture timer value for two consecutive edges on that signal, so I set up the CC1 unit for capturing, and as these events may occur relatively quickly after each other, before enabling the capture (through CC1E flag) I set up the respective DMA channel to be triggered by the capture and transfer the CCR1 register to memory. The DMA is set to be non-circular, so it disables itself after the two numbers are stored. Now processing the numbers and several other things will occur and that might take some time. However, the input signal on TIMx_CH1 is still pulsing quickly, so several other capture events may happen until the capture gets disabled. After some time, there is a need to repeat the process again, i.e. the DMA is set up for transferring two numbers non-circularly, and then the CC1 capture is enabled. However, the first DMA tr

I have made a custom PCB with the Murata CMWX1ZZABZ-091 module. When I try running the LoRa End Node or PingPong example (for LoRa Discovery kit B-L072Z-LRWAN1) , I get "Tx Timeout" on UART. The GPIOs and UART are working fine. How do I solve this?

I posted a tread last week but it soon got buried....So I wasn't able to get any output when probe or read from MISO using Arduino due.and @Bart Herse​  asked me in the post have i connected my IRQ pin. After reading the data sheet I am still not sure what to do with my IRQ signal coming out of ST25. Currently when I probe the IRQ output stays HIGH...I am using the EVAL ST25RU3993here is my Arduino code, I just want to read RSSI information under default set up.#include <SPI.h> //////////////////////////////////////////// //set up pins for arudino due //MOSI:ICSP-4 //MISO:ICSP-1 //SCK:ICSP-3 //NCS:52 //EN:2 //IRQ:22 ///////////////////////////////////////////////   // Set up chip-select pin as NCS and enable pin as EN const int NCS = 52; const int EN = 2; const int IRQ =7;   //SPI setting SPISettings settingsA(100000, MSBFIRST, SPI_MODE0);   void setup() {   pinMode (NCS, OUTPUT); pinMode(EN, OUTPUT); pinMode(IRQ, INPUT); digitalWrite(EN, HIGH);//set

H​ello.I am trying to make a touchgfx demo using stm32f767 apollo board.However, I was stuck while applying a custom external loader using w25q256.I've modified the code from my existing 746-disco demo and it doesn't work at all.Dose anyone have examples or references that use the sw4stm32 compiler and w25q256?Please help me.Thanks.

HelloSTM32CubeIDE has been updated to 1.2.0.TouchGFX can no longer be launched from the configurationHow do I launch TouchGFX from the configuration?Thank you

Has anyone succeeded at it? What did you have to do? I've found a lot of success stories about updating the ST-Link on 32F4 boards but none on the H7. When I run stlinkreflash.exe I always getPreparing for FW update (can take up to 10 seconds)...ERROR: Cannot find an ST-LINK, multiple ST-LINKs plugged in, or ST-LINK is in usewhether on Win 10, Win 8.1, and with nothing else talking to the board it's just sitting there after enumerating as an "ST-Link Debug." Other than this inability to switch it to a j-link I don't see anything wrong with it except it doesn't support the RTT viewer (I don't think it does, correct me if I'm wrong about that and you have my undying gratitude!) and it's comparatively flakey under TrueStudio compared to the J-Link and its gdbserver isn't as feature-rich.

Hello Guys,I hope you all are doing well.I am working on a project that with the VL53L0X ToF Sensor and ESP modules.The sensor works great and i am trying to get deeper into its reads because what i need.I am trying to build a frequency meter using the VL53L0X, to take small vibrations of a surface (starting from 50Hz). I have been trying to read millimeters and put them in a array and making the maths to calculate the frequency, but no luck.Is there any way to read the raw data of the receiver (SPAD) ? Maybe starting a countinous read for 1000ms and getting each signal read and its strenght… i dont know.Or maybe if there is a way to measure the travel time of the signal or the time spent to the signal get from the emitter to the receiver, i could put it in a array to calculate frequency.Normal frequency calc libs are not working on the ESP module because most of them require AVR that is not supported on ESP modules.Would you guys be able to help me to achieve this or how to get the pr

I am working with a project that was generated from CubeMX 5.5, and then TouchGFX 4.13 using the partial project file generated from Cube. The issue I am seeing is everything appears to be working (details below) except I am not seeing any activity on the VSYNC or HSYNC pins. The screen appears all white and does not change.Things I have measured/observed that seem correct:The LTDC clock is ticking at 12MHz.I can see activity on some RGB data pins.I can vary the backlight brightness via PWM as expected.I have inserted counters at various places that I can see incrementing via the debugger, including Model::tick().I can set breakpoints and confirm line interrupts and DMA2D transfer complete interrupts are firing.Additional info: there are no DMA2D errors, and 1 LTDC error (transfer error) that occurs on startup. LTDC global error interrupt is not enabled. I copied CubeMX settings from the STM32H750B-DK examples, except for the sync width settings, which were copied from the screen datas

Hi thereI am currently developing a product and i would like to use either stmb32wb55ce or stm32wb55rgI have done most of the softwaredevlopment on the nucleo board with stm32wb55rg.I am a bit stuck with the analog world on this MCU.I would like to use a 2.5V reference and use ADC.I would like to use the internal 2.5V reference since if I go into standby using RTC to save power and only wake up every 15 minutes or so.I am uncertain as to how VSSA and VREF+ and the VREFBUF should be connected even after going through datasheets.Queations1) I wanted to use STM32wb55ce but according to datasheet VREFBUF is unavailable thus my understanding is i cant use internal 2.5V reference for my adc?2) If i rather use stm32wb55rg I can use vrefbuf and set to 2.5V. IF i do this do i connect Vref+ to VDDA? and ad external 1uF and 100nf cap? Or are they internally connected and i just add 100nF and 1uF to each pin?3) for stm32wb55RG there is no VSSA pin , how is VSSA connected to GND pins? I normally us
