VS Code report: "Unable to contact the STM32Cube registry, verify your Internet connection..."Can I know the registry URL of the STM32Cube bundles registry and test its connection?

My project is using an STM32U575. I have been studying the DfuSe file format and wondered if this can be used to change the values of option bytes. I can see that CubeProgrammer_API used strings such as "-ob nSWBOOT0=1" with sendOptionByteCmd(). If I were to include a target in a DfuSe file whose address is one of the option byte registers, would this successfully change the option bytes? That is to say, is the bootloader smart enough to handle writes to option bytes (presumably by spotting the target address)? In firmware, this is more complicated than writing to regular flash. For context:  We are performing firmware update over USB using the built-in ST bootloader. The update is initiated in the firmware by changing the nSWBOOT0 option bit and resetting, which runs the bootloader. So far, we have then used STM32CubeProgrammer to connect to the device and send the latest BIN image. After that, we use STM32CubeProgrammer to change the option bit again, and then reset to run

It seems like it's been over a year since reports surfaced that the ST-Link interface isn't working on Snapdragons.Are there still no ST-Link interface drivers available for Snapdragon CPUs?

I'm trying to connect my STM32H743IGTX controller with JLINK using cubeprogrammerCLI. I am able to connect jlink with cubeprogrammer gui and able to flash. but when i tried using CLI it shows-------------------------------------------------------------------STM32CubeProgrammer v2.20.0-------------------------------------------------------------------Error: Could not connect to the J-Link/Flasher, Library not found !im trying to use external flash using my custom loader file generated from cubeide.the command i used is,/home/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI -c port=JLINK ap=0 sn=601003130 freq=4000 reset=SWrst -el /home/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/ExternalLoader/XIP.stldr -w /home/project/build/test.hex 0x90000000 -v

Hi I created a new project in STM32CubeIDE, but in Project Manager → Project, the “Generate under Root” option is grayed out and cannot be changed. What’s the reason for this? 

I installed the STM32Cube for Visual Studio Code extension, after which I downloaded STM32CubeMX, STMCUFinder and STM32CubeCLT_1.18.0 and linked them to the extension as seen below:I then opened STM32CubeMX, opened a project using the board NUCLEO-F746ZG, generated the code. The path of the project is: C:\Users\Public\VSCode_Projects\STM32\STM32_TestingHere are the files in the folder:In VS code, I click on "Import CMake Project" and I click on Import project option in the screenshot belowHowever, after that, the project does not open, and in the bottom bar VS code says "Importing project". The bar has been displaying that message for 2 hours now, yet a project hasn't opened. May I know what I could be doing wrong? Thanks! 

in debugging mode the values of variables gets corrupted when I check in live expressions. Here corrupted means shows wrong values.

Hi,I’m working with an .ioc file to generate functionality, but the changes I make in the .ioc file are not being reflected in the generated code. I can see the updates inside the .ioc file itself, but the code generation does not apply those changes.Has anyone faced this issue before or knows why this might be happening? Any suggestions would be greatly appreciated.

Hii Everyone, I am trying to debug with SWO and SWV in STM32CubeIDE with NUCLEO-H753ZI. But, I am not getting any prints on SWV ITM Data console. As you can see all settings in the below attachments. My CPU system clock is running at 400Mhz. Anyone suggest me to get prints in SWV/ITM Data console.    

Greetings, I'm trying to set up Visual Studio Code to work with STM32 microcontrollers. I've installed the STM32 VS Code Extension, as well as CubeCLT, CubeMX, and FINDER as requested, all with the correct versions to ensure functionality. I've also defined the correct paths. However, the issue I'm facing is that it doesn't detect the workspace libraries like those in CubeCLT, nor does it seem to find the compilation path. I'm encountering many errors. I've tried including absolute paths in c_cpp_properties.json, and some of the issues seem to be resolved, but I've tried a bunch of addresses and not all of them are fixed. It doesn't recognize uint36_t or GPIO defines. Does anyone know what might be happening?

Hello,I am trying to get this STLink-V3set to connect for an STM32 board that my electronics engineer has designed.  Due to being at different locations, I need to get it linked at my location.  Several efforts have been made to install the software, install the driver, look at device manager, etc.  to no avail1. The COM light goes on when plugged into the USB on the computer2. The windows tone is heard when the plug in occurs.3. The STCube software consistently does not recognize the STLink.Preliminary questions1. To get a connection shall I have my board attached to the SWD pins or not, shall it be disconnected from my board?2. Is power supposed to be lit in the interface box? I only get COM to light up, not PWR How do I get this connection going?Below is a photo of my hookup, and a screenshot of the typical response I see from the STCube software.Thanks! 

This (DMA_STR0_IRQHandler) won't, but this (DMA1_Stream0_IRQHandler) is work-fine.Clearly, the naming and cases are different, but these two handlers are part of startup file, were generated from two different projects options (Empty and Cube MX) for the same MCU (STM32H723).Project-generated option: Cube MX.word DMA1_Stream0_IRQHandler /* DMA1 Stream 0 */.word DMA1_Stream1_IRQHandler /* DMA1 Stream 1 */.word DMA1_Stream2_IRQHandler /* DMA1 Stream 2 */.word DMA1_Stream3_IRQHandler /* DMA1 Stream 3 */.word DMA1_Stream4_IRQHandler /* DMA1 Stream 4 */.word DMA1_Stream5_IRQHandler /* DMA1 Stream 5 */ Project-generated option: Empty.word DMA_STR0_IRQHandler /* DMA1 Stream0 */.word DMA_STR1_IRQHandler /* DMA1 Stream1 */.word DMA_STR2_IRQHandler /* DMA1 Stream2 */.word DMA_STR3_IRQHandler /* DMA1 Stream3 */.word DMA_STR4_IRQHandler /* DMA1 Stream4 */.word DMA_STR5_IRQHandler /* DMA1 Stream5 */.word DMA_STR6_IRQHandler /* DMA1 Stream6 */I encountered this in the past and solved it by unif

For background see:  https://community.st.com/t5/stm32cubemx-mcus/stm32cubemx-6-2-1-for-nucleo-h745zi-q-doesn-t-generate/m-p/226159/highlight/true#M10675In many embedded systems most peripherals are off most of the time, for power saving, and they are enabled only when needed.  When CubeMX moves peripheral clock configuration from the MSP file of the HAL peripheral to PeriphCommonClock_Config() it makes this behavior harder to achieve.  Is there an option to tell CubeMX to leave clock configuration in the HAL MSPs rather than creating the shared function ?

hello~~NUCEO-stm32h563zi external loader => data read failed. I attaching ld file and source file.let me know how  to solve. please thanks 

I am able to create C++ project in STM32CubeIDE, like so:However, I can't find a way to do the same in STM32 VS Code. Is there such a feature in VS Code for STM32?

Hi all,With STM32CubeMX 6.15 and STM32H723VGH, I try to configure the Quad SPI on OCTOSPI1 but it seems CubeMX does not autorize this functionnality. All modes are selectable (single, dual, dual-single, dual-dual...) but only the Quad SPI is not selectable.If I try with the release 6.14, the Quad SPI is selectable.Does anyone have the same issue ? Is there any solution ? 

Firstly, the installation process is pretty ugly and the documentation is very sparse.From the README.md file:This application runs from the external Flash memory (LwIP_TCP_Echo_Server Appli).It boots from internal Flash (Template_XIP_Boot) then jumps to the application code in external Flash.To configure STM32CubeIDE Debug Configuration, you must do the following : 1. Upload the template XIP2. Add the adequate external loader (MX25UW25645G_STM32H7S3L8-NUCLEO.stldr file) in Project->Debugger Configuration3. Add in the startup the template_XIP_Boot in Project->Debugger Configuration4. Move up the application in the startup Step 1, real helpful, what an ordeal.Step 2, could not find MX25UW25645G_STM32H7S3L8-NUCLEO.stldr used MX25UW25645G_NUCLEO-H7S3L8.stldr insteadEnvironment:STMCubeIDE V1.19.0STMCubeMX V6.15STMProgrammer V2.20.0ST-Link F/W V3J16M9 My problem:When I run the code in debugger mode, execution never gets out of Template_XIP_Boot.Ends up in error handler.

Hi there,So I'm using STM32CubeIDE as is the program we use in Embedded Systems subject at my university. I installed it on Arch with GNOME 49 Wayland (I know, they hate each other) and I'm passing the GDK_BACKEND=x11 environment variable. I've already fixed the debugger not having the proper libncurses version and now I can upload code to the board but I cant visualize IOC files, board selector, etc. Any help would be very appreciated.Thanks in advance!

Cube MX does not allow LWIP to be configured without the Ethernet controller enabled - for some strange reason. Any assistance would be appreciated.

Hello,I am trying to get SWO output working in VSCode using the Cortex-Debug plugin (v1.12.1).My setup:Debugger: STLink V3-MINIEMCU: STM32H747IIT6IDE: VSCode with Cortex-DebugGDB Server: OpenOCDDebug config: Trace Asynchronous SW enabled in CubeMXWhen I run the project in STM32CubeIDE, the SWO output works as expected.However, in VSCode I don’t see any SWO output in the terminal.I overrode the write function like this:int _write(int file, char *ptr, int len) { int dataIdx; for (dataIdx = 0; dataIdx < len; dataIdx++) { ITM_SendChar(*ptr++); } return len; }My launch.json:{ "name": "CM7 SWO", "cwd": "${workspaceRoot}/CM7", "type": "cortex-debug", "executable": "build/Printf_CM7.elf", "request": "launch", "servertype": "openocd", "gdbPath": "/opt/ST/STM32CubeCLT_1.19.0/GNU-tools-for-STM32/bin/arm-none-eabi-gdb", "device": "STM32H747IITx", "svdFile": "/opt/ST/STM32CubeCLT_1.19.0/STMicroelectronics_CMSIS_SVD/STM32H747_CM7.svd", "configFiles": [ "interface/stlink.cfg", "ta

I have spent about 1 day trying to get the latest pre-release version of the extension to install correctly. If only appears to be installing 2 of the bundled extensions, Memory Inspector and CMake Tools, out of the 15 extensions that are included in the bundle. No extension icon is appearing in the left panel and when I go to Settings/Extensions the extension is not listed.I've read another thread of someone reporting the same problem, but I could not determine a concrete solution.Is there a way to manually install this extension and the extensions in the bundle?

Has anyone worked with the Serial Wire Viewer on an STM32H7RS board?We've been using it on a F7 board, without too much issue, but we are stuck on this new board. We've followed the usual steps :- Enable Serial Wire Viewer (SWV) in Debug configuration (using the CPU Core Clock)- Overwrite the "_write" function to use ITM_SendChar(...) (also tested that it works and calls it for every character we send with printf()- Open the SWV ITM Data Console, enabling port 0 and start trace. However, nothing appears in the console :( We double checked the clock ..We also tried to enable the debug mode for our application (although, it doesn't seem to change anything in the code)But so far nothing..One thing to note is that our application uses ThreadX and NetXDuo (I don't know if it has an impact...)We are also using a simple STLINK-V3 connector to debug

STM32H7 + SDIO + FATFS(use DMA template Disable) => works fine. I can read data from SD card without issue. STM32H7 + SDIO + FATFS(use DMA template Enable) => mount will fail The only difference is "use DMA template". Once this option is turned on, fatfs mount will fail...
