Hello everyone! My problem is supposed to be a very simple one. I use an interrupt to send messages to my PC, then I send a message back to my STM32. The message is received in good order but I can't print it out. I watched every single YouTube video out there, implemented every single solution (including connecting the SWO to the PB3 pin) - nothing works so far.Can anyone tell me where am I mistaken? My Debug Configuration:Main.c, main.h, and syscalls.c are attached

My laptop died so I scrambled and got another laptop up and running.  I went from the i9 to the i5.  I used to have STM32CubeIDE 1.18 which worked just fine.  I installed it and STM32CubePrg.  It built code just fine. On my "new" laptop I downloaded 2.0 and installed it and STM32CubePrg and STM32CubeMX.  However, now when I try to create a new project I don't see STM32 C/C++ Project.  I see File->New->C/C++ Project or File->New->Project There is no STM32 listed at all.  Did I miss something in the install?  And if I try to build the "hello world" file it asks for "Cross compiler prefix" and "Cross compiler path".  I thought that was supposed to be built into the IDE.  What am I missing? Did I download a brain-dead version of the IDE?  It must be, because every time I try to download a file from ST.com I must "Update profile" and then the download happens.  If I try to download a different version I m

Hello,I had developed my firmare in STM Cube ide 1.5.1 (stm32h7/)Project repo is here: https://github.com/silelis/MustangRadio_develepementVersion/tree/main/02_Firmware/02_STM32/Radio_mainAnd after I have updated IDE to 2.0.0 I have noticed that STM32h7 falls into hard error interrupt.It also appears when I uninstall IDE and installed pure 2.0.0.When I moved back to 1.5.1 hard errot dissapired. Please check this error in IDE.

Hi, I am really struggling to get clangd to work correctly in a setup I am trying to get going. I'm new to this VSCode workflow, and am finding VSCode seems to have a lot of persnickety behaviors that really require a lot of specificity to get things working right. Here is what I am trying to do:I start with a fresh workspace, and ONLY the STM32Cube vscode extension pack installed. I add two folders to my workspace:an stm32 project folder, as created by cubeMXa shared_code folder, which contains multiple subfolders, each of which contain .c/.h files. Nothing particularly fancy here. I can get this setup compiling fine, but clangd is complaining about various #include files in my shared code area. I understand that the reason for this is because there is no .clangd file in my shared_code area, so clangd can't "see" it from my project area. Intrepid internet searching has led me to adding this to my code-workspace file:{ "folders": [ { "name": "stm32_project", "pa

Hi,I have three small suggestions to improve the CMake build system generated by STM32CubeMX to be used by VS Code to fix some annoyances. 1.In cmake/stm32cubemx/CMakeLists.txt, useset(TOOLCHAIN_LINK_LIBRARIES "-lm")instead ofset(TOOLCHAIN_LINK_LIBRARIES "m")This way CMake knows that the "m" library is an external one. When the user setsset(CMAKE_LINK_LIBRARIES_ONLY_TARGETS ON)in the "CMakeLists.txt" in order to help finding issues in complex project setups, the old behaviour causes a CMake error as there is no explicit "m" target, but with "-lm" CMake is happy. Being able to use "CMAKE_LINK_LIBRARIES_ONLY_TARGETS" is desirable as it helps finding typos easily when many targets/components are defined across many individual CMake files.2.In cmake/stm32cubemx/CMakeLists.txt, usetarget_link_libraries(${CMAKE_PROJECT_NAME} PRIVATE ${MX_LINK_LIBS})instead oftarget_link_libraries(${CMAKE_PROJECT_NAME} ${MX_LINK_LIBS})i.e. use the explicit syntax. When the user wants to refer to addition

Hello,I used vscode with st externsion Ver3.6.4. One day, suddenly, VSCode started showing many red lines and warnings, including "main.h" source file is not valid UTF-8 clang (invalid_utf8).the file looks like:and many other redlines, because of clangd.how can fix it?  it makes file very ugly, evenif it can be compiled no error.Thanks.

Is there an option in the STM32CubeIDE settings to reset to factory settings or something like “Default Settings”?I can’t restore the console window to its original state. When I compile the code, the console window used to appear at the bottom, but now it doesn’t show up anymore.

IDE hangs after collapsing ( minimizing window) and expanding (maximizing). Or after Alt + Tab. From time to time."File -> Restart" only helps.I don't know how to fix this. Please, help.Tried to reinstall - the same situation. IDE uses internal Java: java.version=17.0.11As system Java versions, I have v.18, 21, 22  (checked via "update-alternatives --config java" command) Just have an idea to try to switch from internal to system version of Java, but did not find how it can be done. My config:Laptop Dell Vostro 3520Ubuntu 22.04.4  

Hi, I am using 2 FDCAN ports on my custom board with STM32G0B1x MCU. As per application note AN5348, I can set message RAM offset for second port. But I don't see this setting in STM32Cube MX. As per reference manual, I got following details: But I am not sure where to set start and end addresses. Please help. Thanks, Pradeep      

Hi, the current STM32CubeIDE for Visual Studio Code 3.6.4. (and maybe before) "Create empty project" generates in CMakeLists.txt # Core MCU flags, CPU type, instruction set and FPU setup set(cpu_PARAMS # Other parameters # -mthumb # -mcpu, -mfloat, -mfloat-abi, ... )The comments are misleading, because in cmake\vscode_generated.cmake:set(cpu_PARAMS ${cpu_PARAMS} ${CPU_FLAGS})and therefore, my cpu_PARAMS will be combined with the CPU_FLAGS which already include -mcpu etc.which effectively overwrites my settings.hthKnarfB

Hello Community,I have been working on a BLE project with one service and three characteristics, two of which have server notification properties, and I have noticed the following issue in CubeMX 6.15 (server side, custom template).The function Custom_<CHAR_NAME>_Send_Notification() is no longer auto-generated in custom_app.c if the length is greater that the limit supported by aci_gatt_update_char_value(), which is (BLE_CMD_MAX_PARAM_LEN - 6).In past CubeMX versions, any char with length greater that such limit genered of a function that internally called aci_gatt_update_char_value_ext(), which indeed supports chars up to 512:void Custom_CHAR_Send_Notification(void) /* Property Notification */ { uint8_t updateflag = 0; /* USER CODE BEGIN Data_NS_1*/ updateflag = Custom_App_Context.Data_Notification_Status; /* USER CODE END Data_NS_1*/ if (updateflag != 0) { Custom_STM_App_Update_Char_Ext(Connection_Handle, CUSTOM_STM_CHAR, (uint8_t *)NotifyCharData); }

Hi, When I create a new project on STM32CubeMX, it either freezes when I try to set up some peripherals, or I just get a blank screen when I try to reopen the porject after generating the code. I have tried rolling back to an older version, completely reinstalling, tried it on an ubuntu VM, switched devices, but nothing worked. kind regards, Sam

Hy,I try to configure MCO2 as adjustable clock out. For evaluation I use STM32N6 DK and STM32CubeMX 6.16.0 and STMCubeIDE 2.0.0I use all different settings and it works fine, but IC20 div setting has no effect. When I compare generated code, I see no difference, no matter what setting I put in IC20 div, neither changes the clock output frequency. RegardsHarald

Hi, So i am using STM32CubeIDE to program my STM32 card, except that when i create my project, it doesnt generate an MX file. So when i try to include the library "stm32fxxx_hal.h", it doesn't work. Why is that? And am I obliged to work with STM32CubeMX in parallel with STM32CubeIDE?PS : I use the latest version of the software, and my card is an stm32f303RET6.Thank you.

Launched STM32CubeProgrammer v2.20.0 after a long time since last use - it prompts an update available via an icon button.Clicked the icon, clicked Next, ticked a box, clicked "install Now", it starts download ing a big file...When the file has finished downloading it then displays an error message - see attached screenshot.Unable to unzip file: /home.main/.STM32CubeProgrammer/downloads//STM32CubeProgrammer2.21.0_linux64.zipNote the double slash // in the path.Also tried launching it direct from a terminal prompt out of my /opt folder.... same result.  

Hi,Recently, updated to 6.16.1 on Linux.On a fresh project i get the "misconfiguration warning" when i hit "GENERATE CODE" (I use CMake Toolchain). See Screenshot: There you will see simple config for RCC. Got a "green check" symbol but i always get that Warning.On the second Screenshot, I have changed OCTOSPI settings, and it will add itself to the Warning list. I can extend the warning list by just changing any settings. Maybe I really misconfigured something, but I don't see it.I guess it is a bug - I can generate the code, but this Warning might mask real configuration issues in the future.Thx

Hi,I'm trying to work with the STM32N6. I have a NUCLEO-N657X0-Q board.When I use an external debugger via CN1 everything is fine, however I am experiencing a lot of trouble with the ST-Link.It seems like there is a small (0.01%) chance that attempting to access memory will cause the device to lock up.An example of the sort of command that gets sent to the ST-Link is: `[0xf2, 0x07, 0xfc, 0xff, 0x00, 0x34, 0xcc, 0x35, 0x01]`. That is, a simple command to the ST-Link to read or write memory.I am doing this as part of an attempt to implement support for the STM32N6 for probe-rs, however the problem seems to occur even when using ST tools. For example, the following has a good chance of locking up:./STM32_Programmer_CLI \ -c port=swd \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 \ -r32 0x34000000 32768 Once the ST-Link has locked u

Hi,I’m porting the DATALOG2 application fromfp-sns-datalog2\STM32CubeFunctionPack_DATALOG2_V3.1.0\Projects\STM32U585AI-STWIN.box\Applications\DATALOG2to the STM32U575VGT6, but I’m running into issues with the Bluetooth functionality during debugging.

Attempting to download the new STM32CubeMX 2.0 (required since not included in STM32CubeIDE anymore) does not work from your site.https://www.st.com/content/st_com/en/stm32cubemx.html# has links all over the page to "Download STM32CubeMX"...Unfortunately all these links have the same problem: a License Agreement comes up, but when I click Accept nothing happens.There's not an obvious way to download in any other way.

Hello,I got a problem with HAL library 10.4 for STM32L152RE in UART DMA transmission, the data is transmited only one time using the function HAL_UART_Transmit_DMA(&huart3,t_Buffer ,11) using uart3,  after that the UART3 structure keep the "flag" huart3.gState to HAL_UART_STATE_BUSY and all the other transmissions failedit never come back to the  HAL_UART_STATE_READY so it is impossible to make another transmission. I solve the problem by changing this flag state back to "ready" when transmission is done  using indirectly the (callback) transmission interrupt provided in  DMA1_Channel2_IRQHandler but it is not really a solution !! it should be OK once the data has been transmitted properly by HAL_UART_Transmit_DMA. is it a bug in 10.4 HAL STM32L1 release ( maybe previous ones too ) or this behavior is normal and I need to use that "manual solution" ? thanks Thierry
