STM32CubeProgrammer (MCUs)

Hi everyone,I'm using STM32 Cube Programmer CLI to port an SBSFU example to STM32U5G9 platform (from U585). Other than shell script mess and no IOC files in this examples, I've managed to port the example and run it by using ST Link programmer under both Linux and Windows.The problem is that the newest release 2.20 has its J-Link functionality completely broken in Linux (I'm using Kubuntu 22.04 and 24.04, also tested in regular Ubuntu). Any command to STM32_cube_programmer_CLI ends up with:Error: Could not connect to the J-Link/Flasher, Library not found !The underlying issue is that libjlinkarm.so is not linked to the CLI executable: ldd shows it's linked for older versions, but no linkage for v2.20. I'm guessing this has happened since ST was finally moving away from weird versioned so names to non-versioned so's: i.e. libjlinkarm.so.7 -> libjlinkarm.soI'm hoping that someone from ST will read this message since the issue is not possible to resolve without re-linking... So @s

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

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!

 Hi Team, I wanted to cross compile STM32CubeProgrammer API but it seems like we need libCubeProgrammer_API.so to be in the cross compiled version.Can you please help me and provide libCubeProgrammer_API.so file cross compiled for arm-none-eabi-g++NOTE: I have attached screenshot for the same. RegardsDanish Shaikh

Upon launching STM32 CubeProgrammer today, I encountered this dialog:In case the image doesn't show, the text reads:The server connection is not established.The network connection is required to download updates.Please check your Proxy Settings.This thread refers to the same error and is marked "Solved" but the solved problem is actually a different error, described in the same thread.This message does not interfere with programming, but I'd sure like it to go away.

I am flashing a hex file that has power management that enables the low power stop modes. On version 2.17 everything works fine, but when I upgrade to version 2.20 it starts to freeze when the board goes into sleep mode. I have been flashing using the CLI.I have tried multiple times on v2.20 and when I downgrade back to v2.17, it starts working again.I know that it works on v2.15 as well.I am using the exact same hex file each time.**edited for clarification**

HelloI am in the industrialization phase of a product based on STM32G0B0RE.In order to optimize the flashing process for my manufacturer I made a .bat file programming the product the MCU using the STM32_Programmer_CLI.exe commmand from STM32CubeProgrammer. Since I am not using the GUI of STM32CubeProgrammer is there any folder I can delete in the root to optimize the size of the package I'll provide. The STM32CubeProgrammer size is 1,36 Go if I can reduce it to 500 or 600 mO it could be very usefull. Best RegardsThibaud

Hello,I had generated an External QSPI loader for W25Q128JV and STM32H743 some 2 years ago.I originally used it with STlink Utility Programmer and then switched to STM32CubeProgrammer.  All good and working as expected with CubeProgrammer v2.17.I stopped updating the CubeProgrammer as every version after that including the latest v2.20 no longer functional with my custom .stldr file refusing to mass erase the device. Does anyone know what changed in CubeProgrammer support for External Loaders starting with v2.18 ?Thank you,Yuri

Hi. I just ordered a brand new NUCLEO-N657X0-Q, and cant connect to it using STM32CubeProgrammmer. I tried using ST-Link in different modes and reset modes. I also tried using external loader, and discovery under debug authentication, got the error message in the screenshot.Would appreciate some help.

Hello,   the STM32TrustedPackageCreator supports the obk-file-generation via CLI: STM32TrustedPackageCreator_CLI.exe -obk C:\OBKey.xml   This requires a xml-file. The gui-version allows the generation directly from a password. Is this also possible via CLI?   Best regards, Peter

I need to flash signed bootloader and signed firmware for ardupilot the file i am using is arducopter_with_bl.hexafter this I need to erase the entire chip and need to flash unsigned bootloader and unsignedfirmware again so that i can use that again. I want to achieve this without bricking the board because once it has happend.My board does not have BOOt0 pin and it does not have DFU mode. I am using ST-LINK using SWD.If any body can help me th how to achieve this. Thanks in advance.

Dear ST Community.I am designing devices with STM32WL microcontrollers with highly limited board space. I routed out traces for all SWD signals (VDD, GND, NRST, SWDIO, SWCLK)I have my Prototype Board, original ST-Link V2 with V2J45S7 Firmware and STM32CubeProgrammer version v2.20.0. During testing I realized that the connection to Prototype is stable only when I connect all 5 signals. For some reason I thought that "VDD_Target" pin on ST-Link side can be left floating.I have found a previous post:https://community.st.com/t5/stm32-mcus-boards-and-hardware/how-to-connect-the-stlink-v2-to-my-board/m-p/94389but unfortunately in my case I have to have "VDD_Target" signal connected on both ends. When disconnected STMCubeProgrammer responds with error shown below:Do I need to have all SWD signals being connected in order to program my Prototype or is there any hidden option in ST-Link/STMCubeProgrammer that I can turn on, so in final design I can omit routing VDD pin for SWD connector?Kind re

Hi There is a file path window on the Erasing&Programming page.I would like to reset the history because the path history increases every time I change the file I write.Is there a way to reset the history? STM32CubeProgrammer Version:v2.16.0OS:Windows11Regard

Hello,To avoid licensing compliance issues, we can not use Oracle Java, need to use Open JDK instead. When we install the STM32CubeMX or STM32CubeProgrammer, I guess the oracle java will be installed by default. That is to say, It will be integrated into the installation process. Can we change? 

I attempted to download CubeProg from the official ST website, but I encountered the following message and was unable to proceed:"We apologize for the inconvenience, but in accordance with the European Union's Export Regulation 2021/821, the US Export Administration Regulations (EAR), and other relevant rules and regulations, ST is not authorized to allow the download of this software from your country."It appears that the download is restricted in my country(S.Korea) due to export control regulations.This situation is quite surprising.Does it mean I should consider using a different chip instead?regards, 

Hello,I am working with the STM32H7S78-DK board and I want to toggle the LEDs LD1 (PO1) and LD2 (PO5).I followed the instructions from this GitHub resource:https://github.com/ST-TOMAS-Workshop/stm32h7s_workshop/blob/main/1_external_memory/handson/1_extmem_intro.md and this YouTube video:https://www.youtube.com/watch?v=sPiFBzvCWfI&t=945s However, when I try to flash my program into the development board, I get this error: I am not able to program the board because of this.:right_arrow: Can anyone guide me on how to solve this flashing issue?:right_arrow: Do I need to configure something specific in STM32CubeIDE or CubeProgrammer for STM32H7S78-DK? 

Windows for ARM processors has been out for 3-4 years now.  Most of the recent Surface devices use a Snapdragon ARM processor.  I can't seem to find a way to use STM32CubeProgrammer or any other software that requires a DFU connection on these machines.  Am I missing something or are there no DFU drivers for Windows ARM?

I'm trying to develop a script to flash a secure firmware and set the option bytes on STM32H755. (more on that here https://community.st.com/t5/stm32-mcus-security/flashing-sbsfu-combined-binary-to-stm32h755-with-stm32/m-p/836377#M8786) My specific question here is about the -ob option in the cube programmer CLI.  I'm keen to understand the difference between doing set cube_programmer_cli="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" %cube_programmer_cli% -c port=SWD mode=UR ^ -w %fw_bin% %fw_base% ^ -ob nWRP0=0 ^ -ob SWAP_BANK=0x0 ^andset cube_programmer_cli="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" %cube_programmer_cli% -c port=SWD mode=UR ^ -w %fw_bin% %fw_base% ^ -ob nWRP0=0 SWAP_BANK=0x0 ​ Do the two examples produce different operations and if so how?
