STM32CubeProgrammer (MCUs)

I have a custom board with STM32G070RB micro. I programmed the board several times for debugging in the development phase using theST-LINK//V2 in CubeIDE.Now I would like to generate a .bat file to program the boards, but I am facing some problems.My command line is the following (I am using ST-LINK/V2):STM32_Programmer_CLI.exe -c port=SWD freq=4000 mode=UR -e all -w "file.hex" -v -ob RDP=0xBB and it worked well.In order to reprogram the board I did: STM32_Programmer_CLI.exe -c port=SWD freq=4000 mode=UR -ob RDP=0xAA. After this I can reprogram the board using the first command. Everything looked good at that moment, but I tried to program the board again from the CubeIDE (like I did for several times) and the programming from CubeIDE failed. I thought that I have to put the read protection to level; 0 and I tried to send the command STM32_Programmer_CLI.exe -c port=SWD freq=4000 mode=UR -ob RDP=0xAA but no more worked. It responds with "Error: No STM32 target found!" message.I tried t

Hi, I'm trying to use the cubeprogrammer api in my win32 application for firmware update. I'm able to do this, but there's a lot of .dll files that are required and it clutters the entire project. Is there any way you can provide a static .lib (code library instead of import library) file for linking it during compile time? Thanks,Rahul

Due to Company policy, one must use Windows. (board is seen by Windows)Due to ARM, development is Linux based.Therefore: WSL / WSL2Please don't tell me to run Linux tools inside WSL2, many Linux GUI tools crashPlease don't tell me to export Win USB devices into WSL2, the driver doesn't support all protocols yet. The developing environment are in WSL2. I have output files\\wsl.localhost\Ubuntu\home\user\stm32h757i\build\|-- cm4/      # cm4 files`-- cm7/      # cm7 filesstm32h757i_eval.cm4.bin / stm32h757i_eval.cm7.bin <-- No problem to program those filesstm32h757i_eval.cm4.hex / stm32h757i_eval.cm7.hex <-- BAD00001 not aligned errorstm32h757i_eval_cm4.hex / stm32h757i_eval_cm7.hex <-- No problem to program those files.NoteThe contain in the .HEX file has no problemIt seems the STM32CubeProgrammer has problem to handle multiple dot '.' .hex fileSymbolic won't work (STM32CubeProgrammer won't recognize it)WorkaroundCopy stm32h757i_eval.cm4.

I have been using custom external loader for a long time without any problems. I noticed a problem when I tried to upload to a board without an external flash ic. I am using CLI 2.14.0. While mass erase completes in a few seconds under normal conditions, it gives an error after 5-7 minutes on a board without flash IC.Also, unfortunately, the problem varies from computer to computer. I'm testing it under the same conditions on 3 different computers (Programmer and CLI versions are the same). While there is a latency on computers using w11, there is no problem on computers using w10, it responds instantly. I would like to share an example I took when I was at verbosity level 3.

When plugging in a device in DFU mode to a native USB port of the notebook cubeprogrammer reports:When using it over USB HUB or other port the Cubeprogrammer works fine (we never activated RDP).USBDeview shows no difference in the installed drivers. Happens on various machines/pcs/notebooks.

Hello,how can I generate a srec file with option bytes configuration in offline mode?No St-Link and no hardware is connected!STVP is an old tool which can do this simple things.But it does not support all the microcontroller types (stm32Gxx).Thank you for updating the version 2.15 to 3.0 ;)     

In mass production, we install software using cli. Since we know that return 0 means no problem, we manage the entire operation according to return 0. However, we have observed cases where the return is 0 even though there were unsuccessful operations. Also, even if there is an error in the current situation, I cannot find a document regarding their code.I'm currently using 2.14.0. Is there anyone who can help?

Hi all.With build project I can obtain .bin, .hex and .elf file.I need to manipulate the file to add a CRC in determinate position. SO I use .bin (easiest), then convert in .hex and .elf file using:arm-none-eabi-objcopy -I binary -O ihex --change-section-address .data=0x08000000 crc_FlashTest.bin crc_FlashTest.hex arm-none-eabi-objcopy -I ihex -O elf32-little FlashTest.hex FlashTestX.elf The elf file doesn't work: on CUBE programmer (latest version) I got "crc_FlashTestX.elf is an invalid ELF file"Change elf  option on conversion doesn't solve (elf32-littlearm elf32-littlearm-fdpic elf32-bigarm elf32-bigarm-fdpic elf32-little elf32-big). Still the same file.Hex file is correct. Even Iif I try to convert bin (hex) file without my manipulation the conevrtion doesn't match and doesn't work.Have someone a suggestion?Thanks!

I have got an Nucleo L073RZ   ( and also a discovery 407,F410RB and 4 more nucleo boards) .   It is a new board just unboxed .  I can see it as a drive  in my computer beside disks  so I know it is working.   But st link cannot detect it.   All my  boards except discovery board have same issue. I have tried 2 computers, windows 10 and windows 11 .   I used to program one of the nucleo board. More details: In one of the board the st link made me upgrade firmware , still same issue is there.   

Dear ST I tried to connect with MCU "stm32l07x using STM32CubeProgrammer as below image 1, image 2. Board power is 3.09V to be measured by ST-Link.However, I can't program it.  carefully check the st-link pin maps as VCC(#1), SWDIO (#7), SWCLK(#9), RST(#15), GND(GND). In here (#1), (#7), (#9), (#15), (#GND) is for 20 pins header. VCC/ SWDIO/ SWCLK/ RST/ GND is for ST-Link. Please hint me on how to trobleshoot for it. Thanks advance.Best Regards, Kevin, 

Hi, I've developed a custom ExternalLoader for STM32U575VGT6Q installed on my board, following the online guides provided by ST, obtaining a fully functional version. On the new version of the board I have an STM32U545VET6Q, so in ExternalLoader project I've carried out the necessary porting for the new micro pinout, and the memory was replaced with a larger one but with the same interface.On the new version of the board with STM32U545VET6Q, my ExternalLoader has been successfully tested in debug, both in reading and writing, but it does not work when launched from CubeProgrammer (with both versions 2.13 and 2.14 of CubeProg, the only ones that support U545). I attach the CubeProgrammer logs in the two cases, obtained with Verbosity Level 3. I've tried to read small portions of the external flash, but the CubeProgrammer interface always shows the error message when reading (same behavior for writing).From the logs (the figure below shows an extract of the reading procedure for both mic

Hi, I am a beginner in STM32L4. I set DBANK unchecked accidentally in STM32CubeProgrammer on STM32L4S7ZIT6. Now I want DBANK to be checked, but I don't know how to do. I try check DBANK and apply, but fall. It give me 2 errors. (after read, the DBANK still unchecked)Some other reference:I try to use Full chip erase, it success. But show the address I haven't see before.when I download SBSFU in this board, it fall.I want DBANK to be checked and become normal (when DBANK is checked, I can download SBSFU).It will be very helpful if any one tell me something. Thank you.  

Hi! I am designing a custom external loader for a OCTO SPI HyperFlash with a page size of 512 bytes. I have most things in place but still struggles with the way CubeProgrammer seems to be calling the Write() function..   More specifically CubePogrammer: 1. Does not pack data in a full page size when programming smaller loads For load sizes bigger than 64 bytes but less than a page size, CubeProgrammer always calls Write() twice. Why is this? In such case the second call always seems to have a size even divisible by 32. As an example, programming 84 bytes will result in a first and second call to Write() having 52 and 32 bytes sizes respectively. There is a similar effect also when writing bigger data sizes. Unfortunately, this is a problem for me since the memory I am using does not allow writing data two loads in an address sequence unless the first write ends with an address even divisible with 32 bytes. By other words, the opposite to how CubeProgrammer works.   2. Someti

The devices I try to flash are H745 and H747 discovery boards, one is a partner vendor HMI, but supported by ST. They all use pretty complex QSPI memory layout, but flashing them using TouchGFX Designer and STM32CubeIDE works.But STM32CubeProgramer, despite using exactly the same image files (hex or elf) - works RANDOMLY.If the device is in the "right" state (whatever "right" means here) - it works. I can repeat the process over and over again and it always succeeds. However, anything goes wrong (like I aborted flashing once) - the device looks bricked. I can connect to it via SWD, but it doesn't download any files to it, I get "Failed to erase memory".However, I use the flashing option from the TouchGFX Designer and it flashed the device without problems. Then flashing from Cube Programmer works too.Another case: whenever I use STM32CubeIDE to debug my project, the Cube Programmer cannot be used, it shows the same error. My solution is to use STM32CubeIDE "Run" options (not "Debug"!),

"DCMI_SnapshotMode DCMI Snapshot Mode example"I am a beginner and would appreciate help with the following Readme.txt:"In order to make the program work, you must do the following :- Open your preferred toolchain- For each target configuration (STM32H747I_DISCO_CM7 and STM32H747I_DISCO_CM4) :- Rebuild all files- Load images into target memory- After loading the two images, you have to reset the board in order to boot (Cortex-M7) and CPU2 (Cortex-M4) at once.- Run the example"I hope the attached photo indicates that I have completed "Load images into target memory".How do I complete the remaining steps?

Hello  I am getting a massgae that i have a Server connection is not established  Please advise how can I set the HTTP proxy and Port  Please advise 

Hello,I am doing some programming with the STM32CubeProgrammer. The metadata is programmed as follow:   P 0x06 metadata1 Binary mmc0 0x69000 metadata.bin   The tool returns an error because the expected address is *NOT* 0x00080000. I can see this address being used in the example online. In my current situation, the address used is different. I checked the mtd partition on the target and the address is "as expected." The command "part list mmc 0" returns 0x00000348 address which is 0x69000 if you multiply by 512.How can I make the progammer happy?

Hi,I've just downloaded the STM32CubeProgrammer software in order to build a C++/QT project with it.As I was adding the CubeProgrammer_API.dll into my project, i found that i needed some QT5 dlls dependencies such as : Qt5Core.dll Qt5Script.dll Qt5SerialPort.dll Qt5Xml.dllthe problem is that i'm using QT6 in my project ! is there by any chance a version that dont need QT or at least QT6 ?is there any source code that i could compile on my side in order to update those dependencies ?Thank you in advance for all the support you can provideRegardsSofiane

Hello, STM32cubeprogrammer fails to install, can you assist?M1 Macbook Pro (Ventura 13.4.1)Java Version = 1.8.0_381STM32CubeProgrammer = 2.14.0 

I updated my old STM32CubeProgrammer to 2.14. Now it  takes a very long time to start... Much more than the time to program the MCU! What is he doing during this time? No doubt marketing exchanges with ST servers. The primary use of this type of tool is to work with the MCU, not to wait for it to finish conversing with ST. Could you go back to a more convenient start time? Thanks.

Hello forum,we are facing a very strange issue with the STLINK-V3MINIE debugger.Controller: STM32G0B1CE seriesSTMprogrammer version: 2.14.0Debugger:  STLINK-V3MINIEwe are trying to connect the device(controller) with the stm32programmer application using STLINK-V3MINIE debugger but every time it is showing the error message as shown below.Error: No STM32 target found! if your product embeds Debug Authentication, please perform a discovery using Debug Authentication.  we tried on two devices (STM32G0B1CE) but it is not working at all. then we tried on another controller (STM32H7xx) and it is working every time with this device.Note: STLINK/ V2  debugger is working fine with both the controller(STM32G0 controller and STM32H7xx)can someone help us out on this issue? we need some input ASAP on this issue.Thanks. 

Hi, are there any information's or app-notes available how to use this programmer over CAN bus. I cant find any information which hardware is supported or how make the can hardware on my laptop visible to the programmer. Thanks for your support!

Hello,I have implemented a little project with a nucleo board with STM32G474RE MPU. The purpose is to manage the firmware upgrade, written in the user flash, from a PC connected via USB interface. The MPU, when boots up, start in the DFU modality since the boot0 pin is high (nSWBOOT pin is also high the first time) and so the program starts from system memory. The PC connects with the DFU, parse an hex file, transforms it  into a bin file and writes the flash directly using the API: sendOprtionBytesCommand() and writeMemory(). After doing that the PC switch the MPU to the user flash calling the API: execute(0x08000000).MPU at this point should modify the option bytes so that all following reset will start from user flash. And that is achieved by setting nSWBOOT0 to 0 and nBOOT0 to 1. There are HAL specific API that can be called to perform  that task. But the problem is that, when the program in user flash starts, there are already errors in the flash status registe
