 Dear SupportI am new to STM32CudeIDE - just downloaded latest v1.19 and opened a new example for Nucleo-H563Zi board, SPI_FullDuplex_ComIT_Slave and its .ioc file, as soon as I opened it, it tell me there is a Clock Configuration issue and need to resolve - as it highlighted in red below, is this a bug? Please advise what i need to do in order to let it work.Regards!Ping  

As of yesterday, since an update hit, my CubeMX view won't render (literally it is just a white background). Tried reinstalling and it renders, until I sign up and it updates again, then it stops rendering again. The rest of the IDE works just fine. System:Ubuntu 24.04.3 LTS (Linux 6.14.0-33-generic)Dell Inspiron computer8,0 GiB MemoryWayland windows systemGnome 46CubeIDE 1.19.0

We have a custom loader from one of our boards.  It is working in STM32 Cube MX Prog V2.16 but when I launch V2.19 and try to connect to a unrelated boards I get this error:The error is understandable because the path to the loaders is incorrect.  The issue is I never told V2.19 to use this external loader and it doesn't even show up in the list of available loaders.  It some how figured out that I have used this loader in the past (but it didn't quite figure out the correct location of the loader) and for some reason it is trying to access it.  I mess with loaders so infrequently I have no idea how to fix this issue.The custom loader does show up in V2.16 and doesn't produce this error: Suggestions? Jacob

Hello,I am using the discovery kit with STM32L562QE MCU (UM2617). I tried to disable the TrutZone following the instructions in this article : https://community.st.com/t5/stm32-mcus/how-to-disable-trustzone-on-stm32u5-series/ta-p/49793However, after doing Step 3 (in the article), I can no longer interact with my card. When I try to connect to it using STM32CubeProgrammer or by flashing, I always have the same error : ST-LINK error : DEV_TARGET_NOT_HALTEDI found some persons with the same problems :- https://community.st.com/t5/stm32-mcus-boards-and-hardware/st-link-error-dev-target-not-halted/td-p/278454- https://community.st.com/t5/stm32-mcus-boards-and-hardware/error-in-initializing-st-link-device-reason-9-target-not-halted/td-p/85174But the solutions described do not seem to work for me. Here is what I've tried :- Power off / Power on- Update STLink- Set NRST to high (because there are many NRST on the board, maybe I did not set the right ones)- Switching to

Please read this post: How to insert source code Hi everyone, I’m interfacing a microSD card with an STM32U575 microcontroller using the SDMMC1 peripheral. In my project (generated by CubeIDE) I’m using the MX_SDMMC1_SD_Init( ) function to initialize the peripheral. Everything works fine when the card is inserted. The problem occurs when I remove the microSD card (or if it’s not inserted at all): during initialization, the code stops at this point: /* Identify card operating voltage */ errorstate = SD_PowerON(hsd); if (errorstate != HAL_SD_ERROR_NONE) { hsd->State = HAL_SD_STATE_READY; hsd->ErrorCode |= errorstate; return HAL_ERROR; } This condition returns HAL_ERROR, which is then handled by the default Error_Handler( ) function. However, the default Error_Handler( ) generated by CubeIDE contains a while(1) lo

Created a STM32H743II prj with I2S2 enabled, half-duplex slave receive mode, and DMA1 S0 bounded to SPI2_RX, to work with an ADC in master mode. Can't get data from the ADC ( DMA linked mem area always zero ), while my oscillograph can properly decode the ADC I2S data output pin ( CK & WS pin also connected between the ADC board and the H743 board, and the oscillograph ). In cube, the SDI pin is mapped to SPI2_MISO, PB14. But as a slave, shouldn't the correct SDI pin map to SPI2_MOSI, PB15? So I modified the cubeMX generated code manually, by changing PB14 to PB15 in the I2S2 GPIO initialization sector, and it worked, the DMA linked mem area shows the same value on my oscillograph. Is this a cubeMX bug?

Hi,o.s.: Debian 12 Bookworm (fully updated)board: (official) STM32f4-discoverymicropython: STM32F4DISC-20250911-v1.26.1.dfuSTM32CubeProgrammer v2.19.0Checking my previous posts shows that I have tried this before but obviously got nowhere as I seem to have abandoned that attempt. So I am trying again...I'm trying to load Micropython onto the board listed above using ...Programmer but am having some problems doing so. I have connected both of the board's USB ports to the laptop.When I set ...Programmer connection mode to ST-LINK the board is connected and is erroneously(!) identified in ...Programmer's "Target Information" list as a device of type STM32F2xx. In this connection mode, the board has both ST-LINK jumpers in place and ...Programmer does display a "File download complete" message after downloading the .dfu file even though it is displaying "No DFU detected".When I set ...Programmer connection mode to USB, which I thought was necessary to flash/download a .dfu file t

When I am trying to use the STM32CubeProgrammer in Linux, only the default connection option of J-Link is available. No other options "drop down" in the drop-down menu. Since I am set up to connect over USB, this means I am unable to connect to or reprogram the board (STM32MP257F-DK). When I test this same thing on Windows, it shows USB as a connection option, and it can connect successfully. The drop-down menu appears normal. It used to work properly like this in Linux before, and I don't believe I changed any settings in STM32CubeProgrammer since then. Is there a way I can get the standard behavior back when using Linux? I am following the steps as described here: https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-DK/Let%27s_start/Populate_the_target_and_boot_the_image 

Hello! I installed the extension and configured it to work through a proxy (downloading the compiler, etc.), and everything works fine, but when I try to download devices list via cube pack sync, I get the error: Failed to download with Unsupported `GLOBAL_AGENT.HTTP_PROXY` configuration value: URL protocol must be "http:" I tried adding the proxy via platform environment variables, but that didn't help. Platform: Win11 IDE pluggin: 3.6.4 Pack manager: 0.3.12

Hi,In the old VSCode extension there was a task called something like "Erase + Flash" which would flash the board and then the program could run. After updating, there is now no such task so the only option is to flash the board by debugging. Is there a way to flash the board without debugging?Best regards,Sašo

Hello,Since I installed a new version of linux mint (22.2), I can't upload my programs to the MCU.CubeIde show this error: Could not determine GDB version using command: arm-none-eabi-gdb --versionarm-none-eabi-gdb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory Searching in my system, I found libncurses.so.6, not libncurses.so.5 I read in the forum that I need to install libncurses5, but is not present in my repositories. I found a possible solution adding "universe" repositories sudo add-apt-repository universesudo apt install libncurses5 but libncurses5 still missing I found a post from Semer Cherni (ST Employee) that say that "The Linux Mint 22 is not supported by STM32CubeIDE"This post was written on 2024-10-07 12:12 PM Is the problem still active, or I need to go back to the old version? Thanks  

I'm a new user of the STM32 and its tools, and I'm confused about their behavior when using ST's Arm Clang toolchain (not the hybrid Clang-GNU but the full Clang/LLVM). The ST-provided `cmsis_armclang.h` isn't being included in my build of a simple CubeMX-generated project. Instead, `cmsis_gcc.h` is included.Using the current version of STM32CubeMX (6.15.0), I created a project for the NUCLEO-U545RE-Q board (attached). I used the default settings except that I went with ST's contemporary approach for VS Code with ST's extension pack:Toolchain / IDE: CMakeDefault Compiler/Linker: Starm-Clang. I keep wanting to pick Sturm und Drang but sadly that's not an option. ;)And I modified two of the code-generation settings. From the .txt report:STM32Cube MCU packages and embedded software packs : Copy only the necessary library filesGenerate peripheral initialization as a pair of '.c/.h' files per peripheral : YesThe generated code's `starm-clang.cmake` defaulted to the hybrid toolchain by

Hi I previously used STM32 VS Code Extension to import cmake project and tried to build and Debug using ST-Link.But due to some update in the extension, the STM32 VS Code Extension got removed and replaced by STM32Cube and now i can't able to debug with existing project. If i click debug still loading and some time it is showing "command: STM32VSCodeExtension.bootFlashBootTarget is not found"Can you tell me how to get back the STM32 VS Code Extension.No STM32 VS Code showing (i installed and used previously).Not showing in Extension browser too. @B_Subramanian @Laurids_PETERSEN  Can you please support in this.

Hello,I cant start SDRAM to work, I ques what FMC controller do not initialize interface correctly because CLK is dead (bug !?), there is no activity at all, I connected oscilloscope to CLK output to check, if I toggle manually the pin PD9 (FMC_SDCLK) is changing state, there is no difference what frequency is set and what is RCC source, now CLK is set to 50Mhz, source IC4 100Mhz, similar code on H7 works without problems even if frequency is to high for my SDRAM 143Mhz (tested - works well up to ~165Mhz), there is initialization code:static void MX_FMC_Init(void){ /* USER CODE BEGIN FMC_Init 0 */ /* USER CODE END FMC_Init 0 */ FMC_SDRAM_TimingTypeDef SdramTiming = {0}; /* USER CODE BEGIN FMC_Init 1 */ /* USER CODE END FMC_Init 1 */ /** Perform the SDRAM1 memory initialization sequence */ hsdram1.Instance = FMC_SDRAM_DEVICE; /* hsdram1.Init */ hsdram1.Init.SDBank = FMC_SDRAM_BANK1; hsdram1.Init.ColumnBitsNumber = FMC_SDRAM_COLUMN_BITS_NUM_9; hsdram1.Init.RowBitsNumber = FMC_

 Hi!I try to read data from an I2C device using DMA. I use a STM32-F412ZG nucleo board.First I try to write without DMA : HAL_FMPI2C_Mem_Write(&hfmpi2c1, 0x52, 0x7fff, FMPI2C_MEMADD_SIZE_16BIT, tab, 1, 1000); Then I want to read data using DMA with: HAL_FMPI2C_Mem_Read_DMA(&hfmpi2c1, 0x52, 0x0, FMPI2C_MEMADD_SIZE_16BIT, tab, 1); Here is what i get with the osciloscope:The first part corresponds to the write and works correctly. The second part corresponds to the read function, but the address of the register should be a16 bit sequence, but i only get the first byte, then the I2C bus is stuck (sclk stays at 0V).I tested the same thing using I2C instead of FMPI2C, and all works correcly.Did I miss something in my code? the full project is attached.Léonard G

Follow-on from: Help for porting from MDK to CubeIDE.HiI am now working on porting an MDK example to CubeIDE on an F767-based customized board with 32MB SDRAM and an LCD interface.At the moment, the build of the ported example in CubeIDE gives following erorr message:The following is the original code of the example targeting on ARM compiler:static __align(64) uint8_t mem1base[160*1024]; static __align(64) uint8_t mem2base[28912*1024] __attribute__((at(0XC01F4000))); static __align(64) uint8_t mem3base[60*1024] __attribute__((at(0X20000000))); static uint32_t mem1mapbase[160*1024/64]; static uint32_t mem2mapbase[28912*1024/64] __attribute__((at(0XC01F4000 + 28912*1024))); static uint32_t mem3mapbase[60*1024/64] __attribute__((at(0X20000000 + 60*1024))); Now after the porting, the code is changed to:/* mem1 (internal RAM) (64 bytes alignment) */ __attribute__((section(".mem1base.mem1_base"))) static uint8_t mem1base[160 * 1024] = { 0 }; // mem2 (32MB external SDRAM) // 64 byt

Hello,I try to do a little code for STM32F103 MCU using Visual Code Studio with STM32 VS code Extension.I can generate and compile base code using STM32CubeMX importation feature.But I'm stuck with adding external libraries to the project.What i've done is to modify the "c_cpp_properties.json" file of the project to add the path to the library I want to use.Here the current file : { "version": 4, "configurations": [ { /** * ms-vscode.cmake-tools plugin should be installed. * * It provides data for C/C++ plugin, * such as include paths, browse paths, defines, etc. */ "name": "STM32", "includePath": [ "lib/ssd1351" ], "configurationProvider": "ms-vscode.cmake-tools", //"intelliSenseMode": "${default}", "intelliSenseMode": "gcc-arm" } ] }  But when I include the ssd1351.h header in the main.c file, it fail :  /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include "ssd1351.h" /* U

HiI am trying to port an example application from MDK to CubeIDE, the CubeIDE does not give me correct compilation result:1. It completes the compilation when code contains syntax error and it produces binary. This is quite different from past experiences with CubeIDE.2. The size of the binary is not correct (88 bytes for an LWIP application is imppossible)3. The CubeMX does not generate startup code startup_stm32f767igtx.s4. There's a warning: cannot find entry symbol Reset_Handler5. MDK uses ARM compiler, therefore how to rewrite the following delarations in CubeIDE:#if !(__ARMCC_VERSION >= 6010050) /* not AC6 compiler */ /* use AC5 compiler */ /* the following 3 declarations are reported syntax error by CubeIDE */ /* internal SRAM */ static __align(64) uint8_t mem1base[MEM1_MAX_SIZE]; /* external SDRAM */ static __align(64) uint8_t mem2base[MEM2_MAX_SIZE] __attribute__((at(0XC01F4000))); /* internal DTCM */ static __align(64) uint8_t mem3base[MEM3_MAX_SIZE] __attribu

STM32CubeMX always generates the function MX_LWIP_Init even when its generation is disabled. This causes a redefinition during compilation if a custom implementation already exists. On every regeneration the autogenerated file re inserts the function and its prototype, triggering the conflict.Board: CustomCPU: STM32H743IITx

I am working to send data continuously using TCP/IP, LWIP and free-RTOS. I created three tasks and using one task to send data. Each data packet is 1460 bytes and after sending around 300K packets the system halts and resets. I wanted to increase the size of descript ETH_RX_DESC_CNT and ETH_TX_DESC_CNT from 4 to 8 to check the performance. I do not want to change it in .ioc file as it will generate code again that will result in deletion of my code. I tried to redefine using every method, in compiler preprocess, main.h, stm32h7rsxx_hal_conf.h, stm32h7rsxx_hal_eth.h, ethernetif.c but nothing works. The value remains same 4U (default).How I can do that?Edit: I am using Nucleo-H7S3L8 board
