I want to launch an external windows application when a successful build in SW4STM32 is happened.

When working with STM32CUBEMX. After I clik to Generate Code, and want to open the project I get the message>"Install SW4STM32 Toolchain to open the project.Thank you for you help!

Hi I am using STM32L151RBT6 controller card. This was working properly also there was no issue in debugging. I am using IAR Embedded Workbench 6.4.I Added this line to my code: FnEraseEpromWord(0x080800F5,1); as because I want to erase data for this address. After executing this line debugger was stopped.After that I am not able to debug my code this shows following errors:User Error: Reset failed-Target not Halted.failed to load flash loader.Please help to find out the solution.Thank you.

I want to know the build number of a program in SW4STM32.

Want to use the date and time of build as build version

I have made a new GIT repository of an existing TrueSTUDIO project. But this message is show when opening the project in TrueSTUDIO:" No target settings could be found for this project For proper operation of TrueSTUDIO these settings must be set. "Further, the project does not compile as all of the library paths have been deleted.-thanks

Mbed-os currently does not support STM32H745. When will the STM32H745 be used on mbed-os?

Hello,I have a strange behaviour that I cannot explain. It is regarding the determinism of running code. My setup is simple. I have a save routine that save some setup in two seperate pages (two copys of same data). So my saveroutine consists of one write function that is called twice with different adressoffsets and then stores some 60 values. Nothing wild, just a simple copy. Now I wanted to check how long the writeing takes. Naturally I would expect the write routine to take amount N time and the entire save 2xN (give or take a few µs). Interrupts are deactivated during the entire save. Case 1: I set the pin at the beginning of the entire save and reset it at the end. I measure a time of 22 ms.Case 2: I set the pin at the start of each of the two write routines and reset it at the end of each routine. I would have expectet two puleses of about 11 ms. But I get two puleses with 22 ms and a pause inbetween of 10 ms. Note that the only thing I changed in the code is the Line for changi

i got confused about STM32H745I-DISCO & some nucleo board mentioning 'mbed compliant' if i ca used with it mbed & mbed-linux os, i'm getting STM32H745I-DISCO anyways to start with - it's my first ever embedded experience but i am interested in arm mbed and want to know if i can use it with this board

Hi, Since i could not find "general coding" subforum i will post here, even when i dont use TrueStudio. but visualGDB and arm gcc toolchain.so the proplem is here, i'm trying to parse Steering wheel button Can codes from my cars canbus, to detect if it was long pressed or just tapped, to get some more functionality from the couple buttons i have. I have tested this prototype many months IRL with my daily car and all the other aspects are working great.void __attribute__((optimize("O0"))) AdvancedMappedMessageParser(CanMessage *message, uint32_t time) { uint32_t timeStamp = time; uint64_t currentPayload; static uint32_t lastValidMsg = 0; static CanParserState state = Idle; static CanMessage lastMsg; static volatile uint32_t processingStarted = 0; /* Recover from possible deadlock */ if (message == NULL && state != Idle && time - processingStarted > 1000) { state = Idle; lastValidMsg = 0; processingStarted = 0; return; } if (message == NULL) r

St link Utility is working properly. IAR works well with stm32f4. But it does not work with STM32H747 Disc0, please help me

Hello,we want to add a flash EEPROM emulation to our software, currently for STM32H7 but I think the question also applies to other STM32 families. As the EEPROM contents must be preserved also over firmware updates I think there is a conflict with setting readout protection active. When I want to update firmware I have to unprotect readout which leads to a flash erase and this also erases EEPROM contents.Is there a way around this with STM32?Thanks a lot Martin

Hi,I need to build my IAR-base application with a non-consecutive RAM region.E.G.. if my RAM is between 0x20000000-0x200087FF:define symbol __ICFEDIT_region_RAM_start__ = 0x20000000; define symbol __ICFEDIT_region_RAM_end__ = 0x200087FF; define region RAM_region = mem:[from __ICFEDIT_region_RAM_start__ to __ICFEDIT_region_RAM_end__];I want to exclude a few 'holes', for example, "don't use 0x20000100-0x200001FF".Can this be done only via linker-script, without adding dummy buffers with this-or-that linker flag (.noinit)?If code must be added, I'll be glad for a snippet.Thanks

Hello, I am using stm32f429i discovery boards for spi communication. I am using HAL libraries, trying to send dummy data, but my DR register is not getting updated, , I am using atollic truestudio, I kept the clock of both boards same can anyone help me?

Dear all, I am new in here. I am learning the STM32-MAT/TARGET in PIL mode. I am following the STM32-MAT/TARGET Hands on Rev 2.4. When I run the Test_PIL_IIR_Filter.mdl and complete the parameter setting. I got errors as following:The timeout of 5 seconds for receiving data from the rtiostream interface has been exceeded. There might be multiple reasons for this failure.You should: (a) Check that the target hardware configuration is correct, for example, check that the byte ordering is correct. (b) Confirm that the target is running. (c) Consider the possibility of application run-time failures (e.g. divide by zero exceptions, incorrect custom code integration, etc.). Note (c): To identify possible reasons for the run-time failure, consider using SIL, which supports signal handlers and debugging.If you cannot find a solution, consider using the method setTimeoutRecvSecs of rtw.connectivity.RtIOStreamHostCommunicator to increase the timeout value.My software version:WIN10 (64 bit)MATLA

Hello,Can someone telle me which IAR version that support STM32H747 please ? Regards,

I use Iar Embedded Workbench 8.32.2.194323.I created the project file with Cubemx 5.0 using STM32L496ZGTxP.(Nucleo-L496ZG-P).I didn't nothing in the cubemx 5.0.It works well in STM32L496ZGTx.

Hello,I know that there are voltage/wait states limits for the FLASH memory. Do they apply also for the EEPROM memory? I don't believe so, also the StdLib function FLASH_SetLatency() doesn't have analogous EEPROM function and etc. Also I didn't find anything in the datasheet/ref manual. Thank you!

Couple of complaints over at the Keil forum of the compiler shutting down, new key was published today (02-Jan-2020) to address that.https://www2.keil.com/stmicroelectronics-stm32/mdk

please check the image below. actually i was working on stm32f030c8 for more than a month, but today while debugging i stuck to an unknown problem, my device is not detecting on target. i checked all connections wirings everything multiple times but still couldn't find any solution. but other stm boards with same MCU are working fine. only my board is not getting detected, i also tried with copy of that same Pcb but same problem ocuurs.any help from you will be admired!

Hello EveryoneI am trying to build libcsp source code for STM32F429 Cortex-M4 MCU. I am using Keil MDK-ARM V5.22 IDE for my software development. Please tell me how to configure/change wscript (waf script file) to build libcsp for STM32F429? When I run python waf configure --toolchain=MDK-ARM command I get this message:"Program ['MDK-ARMgcc'] is not executable"Why is there gcc at the end of MDK-ARM toolchian?

Hi,I have a problem about I2C and I saw some topics about my problem on the internet but there was no solution, I hope you help me by sheding light on this.Problem : After sending adress by I2C, the ADDR flag in SR1 register is not set but at the same time AF Flag(acknowledge failure) is setting up. I do not use std peripherial libraries and I use stm32f429I-Discovery kit and AT24C256. I2C communicates at 80 kHzIt stucks while (!(I2C1->SR1 & 0x0002));line, I could not find a solution. Please help me.the code is below:/* Includes ------------------------------------------------------------------*/   #include "main.h"                   int main(void)   {       int slave_adress = 0x50; // eeprom adress   int word_adress = 0x01; // I want to write in this register adress in eeprom.   int data = 0x30; // the data I want to write                   &nb
