STM32CubeProgrammer (MCUs)

Hello, there is a problem with programming STM32G0Bxx/B1xx/C1xx using  STM32CubeProgrammer version 2.16.0  A have a HEX file starting at address 0x8001800 and with length 0x32800. When programming this using USB DFU, the tool first starts to erase some of the sectors first. Which is what i expect. Only the number of sectors and the address go wrong. See part of log of the tool: "14:38:58 : Size : 202.00 KB14:38:58 : Address : 0x0800180014:38:58 : Erasing memory corresponding to segment 0:14:38:58 : Erasing internal memory sectors [1 51]14:38:58 : erasing sector 0001 @: 0x08000800 done14:38:58 : erasing sector 0002 @: 0x08001000 done" As the sector size is 2K for this MCU type, it should erase sector 3 to 103 (or 102)! And it should start at address 0x80001800! Please fix asap. Something similar was already reported by my colleague.   Thanks, Regards, Corné

Hi team Is stldr file supported by Jlink If yes please let me know how to program ?

I'd like to be able to distribute secure code updates (encrypted) to clients along with an application that can program the STM32H743 over USB.The STM32CubeProgrammer works well with our board, but does not provide any security as far as I know for the code files, .elf or others.The idea is to have an application in which we can add code to decode our encrypted source and program the MCU over the USB link in boot mode.I am sure this would be useful to other developers needing to securely distribute code updates to clients or remote machines.

I am running into the same issue. I cannot download the program- the link is not working.I tried using two different browsers (chrome and edge) and checkout as a guest for both. Pretty frustrating.   

When I'm trying debug my projest I see in console:...Waiting for debugger connection...Encountered Error when opening C:\ST\STM32CubeIDE_1.12.1\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.1.201.202404072231\tools\bin\STM32_Programmer_CLI.exeError in STM32CubeProgrammerShutting down...I checked file location, it is OK, but when I'm trying to start STM32_Programmer_CLI.exe I see dialogas below:Translated to english: "Can not find entry point in procedure CreateEventW in library api-ms-win-core-synch-l1-2-0.dll".My CubeIDE version is:STM32CubeIDEVersion: 1.15.1Build: 21094_20240412_1041 (UTC) OS is: Win7 SP1 64bitWhat can I do to fix this problem?I see that I have another version of STM32_Programmer in path C:\ST\STM32CubeIDE_1.12.1\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.1.100.202311100844\tools\bin\STM32_Programmer_CLI.exeand this one works fine, no errors.

I am trying to test flash integrity function.In order to cause an error I am changing the flash using STM32CubeProgrammer.After changing the data in the flash the firmware can no longer write to the same page until a  page erase. I only try to change bits that are set change from 1 to 0)Why is this happening? 

Ok, this should be a simple matter and I've done this before but I can't recall how I did it.  Not enough continuous exposure  to the platform, I guess.  With the stock SensorTile.box PRO plugged in and using the ST BLE Sensor app I get an immediate notice that a firmware update is available.  Update is applied with no issues, BUT, the actual .bin file is nowhere to be found on the Android phone.  I can find the original firmware file in the ST downloads for this Sensortile.box PRO, file but the updated .bin file appears to be a bit elusive.  Obviously, I can always install the original .bin then upgrade but what I'd like to do is download the updated firmware directly from the PRO to a .bin file on my computer using CubeProgrammer.  I've tried a few things but I haven't been successful.  My memory is missing something in the configuration of CubeProgrammer to make this work. How would I do this?Thanks,TJM

Hello,   I read through the fairly thorough How To Jump To System Bootloader From Application Code on STM32 regarding entering the bootloader from firmware but I am having an issue getting USART1 to work after the software jump.Code is below. I am able to successfully:Software jump to bootloader and access it from USBHardware jump to bootloader and access it from USBHardware jump to bootloader and access it from USART1However, I can NOT do a software jump to the bootloader and then have it work through USART1. Note that I disconnected USB for this test because that can prevent the bootloader from using USART1.Code:void bootloaderJump (void){uint32_t i=0;void (*SysMemBootJump)(void);/* Set a vector addressed with STM32 Microcontrollers names *//* Each vector position contains an address to the boot loader entry point */volatile uint32_t BootAddr[33];BootAddr[C0] = 0x1FFF0000;BootAddr[F030x8] = 0x1FFFEC00;BootAddr[F030xC] = 0x1FFFD800;BootAddr[F03xx] = 0x1FFFEC00;BootAddr[

Hi~ ​I'm trying to connect uart bootloader. but there is something wrong. I can't connect bootloader via STM32CUBEPROGRAMMER​and I found the datasheet that STM32F401 NUCLEO-64 only support one uart for system memory.​ I connect Uart1 (PA9, PA10) I've already checked that Uart1 is working on user FW ( I have tested )I connect BOOT0 and VDD ( I have checked 3.3V )I checked BOOT1 is grounded.I press the reset button.I think STM32F401 NUCLEO-64 is on system memory boot. (cause I programmed blink led , when I press the reset button, it stopped) I am trying to connect uart via STM cube programmer program.but it shows error message that "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... "I used HSI clock which it presented on datasheet.I checked that bootloader FW version , it is D1, ​I don't know what's wrong with this.any Ideas??is that possible to using uart bootloader with STM32F401 NU

Hello all,I am implementing an external loader for STM32F429 and W25Q64. The STM32CubeIDE Version is 1.15.1 and STM32CubeProgrammer is 2.16.0.I success programming a 64k bin file with the external loader while failed to program a bigger size file (150K). The attachments are the logs of STM32CubeProgrammer .The Dev_inf is as below:  struct StorageInfo const StorageInfo = { "W25Q64_STM32F429BIT6_SPI", SPI_FLASH, 0x90000000, 0x00800000, 0x0100, //256b 0xFF, // Specify Size and Address of Sectors (view example below) 0x0800, 0x1000, //4kB 0x00000000, 0x00000000, };   May I have any suggestions on this case? Thanks.

Hello,Is it possible to access to an older version of STM32 ST-LINK Utility (v 4.5.0, in particular). On ST Web portal, I can only donwload latest version (v4.6.0)...See : https://www.st.com/en/development-tools/stsw-link004.htmlThanks in advance for your help.Emmanuel.

Hello everybody,I come back with a similar issue I've wrote in Issue in buffer to write before programming external flash but with a different memory, now is a NOR flash S29GL128S.I can read and write any address of external memory properly. Also I can do sector erase and full chip erase. A corruption data to write happens when it tries a program block of 342324 bytes in the external memory. I guess CubeProgrammer splits the block in 2 blocks because Write function is called 2 times, one with 171164 bytes and another with 171160 bytes. In the second time when Write function is called is when I catch a corruption data.     int Write(uint32_t Address, uint32_t Size, uint16_t* Buffer) { uint32_t i_write = 0; uint32_t word = 0; uint16_t data; #if DEBUG PRINT_HEX_EX("Programming at ", Address); PRINT_DEC_EX("Programming size:", Size); #endif for (i_write = 0; i_write < Size; i_write += 2) { data = Buffer[word]; #if DEBUG // Here is where checks d

Hi, I am working with Open Bootloader and referring to a video tutorial for the same. While I am referring to this video I am not able to set the user firmware address from 0x08000000 to 0x08008000 as mentioned in this video following the same steps for NUCLEO-G491RE. If I view the ELF file for a simple blink program on STM32CubeProgrammer looks like thisIt starts something at 0x08000000 If I scroll down to address 0x08008000 it is like this  For Erase & Programming, it starts writing firmware from address 0x08000000 and not from 0x08008000.What may go wrong?

I cannot uninstall STM32CubeProgrammer v2.16 (64-bit) from my Windows 11 64-bit system.If I try to uninstall it from the Windows Apps->Installed Apps list, a terminal window briefly flashes on the screen and then nothing else happens. If I go to C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Uninstaller and run "unscript.bat" as Administrator, I get this window:Whether or not I select "Force the deletion of ...", when I click "Uninstall," I get an unhandled exception pop-up (I can't find a way to copy the text out of it, sorry), which appears to indicate Access Denied when trying to modify registry keys:My company uses a credentials manager to provide admin privileges as needed when installing and uninstalling apps, and it asked if I wanted to escalate my privileges in both cases (running the uninstaller and running the script directly), but it said the software publisher was "Unknown" as if it didn't install correctly or wasn't signed.I'm at a loss on what t

I am trying to program a chip using an STLINK V2. I am using only SWDIO, SWCLK, and ground, and I am powering the chip with 3.3 V. When I try to connect using STM32CubeProgrammer, it does not connect. Am I missing something?

Hello,The main purpose of the question is to avoid giving source code and give binary file instead.For example, I generate a compiled binary file from a nucleo project (STM32H743ZI2) for the M7 core.Then I want to create a new dual core project (STM32H755ZIT6) but import the previous binary file for M7 (.elf, .hex, .bin or whatever which will work) instead of importing its source code. (this two version of MCU were provided by the company, I actually have not clue if they are compatible)All the tutorials I saw use the importation of source code.In the newly created dual core project, I tried to make:Import> "stm32 Cortex M-executable"> select the generated .elf as executable, select STM32H755ZIT6 as MCUIs this the way to do it ?Is there a tutorial or a post that explained this ? 

Hi,I try to make a external loader for STM32G030. I was implemented function MassErase(), Write(), Read(), Init()...First I test function on "flash" version and everything work. But when I try using it in STM32CubeProgrammer the Write function not working.Full chip erase work ok, and after this operation eeprom is cleared by 0xFF as default data. But when I try write to eeprom, it stuck on "Loader write range..."Both function (MassErase and Write) use this same function to write data to eeprom.What could be the reason that cube stop in this?   13:58:17:879 : Memory Programming ... 13:58:17:879 : Opening and parsing file: test13.hex 13:58:17:880 : File : test13.hex 13:58:17:881 : Size : 128.00 B 13:58:17:882 : Address : 0x00000000 13:58:17:882 : Erasing Segment <0> Address <0x00000000> Size <128>Bytes 13:58:17:882 : Erasing memory corresponding to segment 0: 13:58:17:883 : Memory erase... 13:58:17:883 : halt ap 0 13:58:17:883 : w ap 0 reg 15

my STLINK is not recognized on Windows (Device description failed). I have try to uninstall and reinstall the driver. I try 3 different ST-Link and different laptop, but I face the same problem. previously, I always used those ST-link on my laptop and it was fine.

I launched STM32CubeProgrammerIt does not work.It gives me this error message:***CubeProgrammer_API or one of its dependencies is missing.Please try reinstalling the program or check your java architecture.***I reinstalled it.I updated Java on the system.Nothing.What do I have to do?Can anyone REALLY help?Thanks

I have a project with a large number of image bitmaps I want to draw to a screen, so have set up an external FLASH IC for storing the majority of these images.I've verified my flash driver works and created an external loader for use in STM32CubeProgrammer. I've verified that this loader can read and erase sections of the external flash after I get the microcontroller to write to the flash, so now all I need to do is save the images to the flash from the CubeProgrammer but I'm unsure on what the best route to do this is.I understand CubeProgrammer accepts .Bin and .Elf files to program to the uC/flash but how do I create a .Bin/.Elf file with just images in them at specified memory addresses?Thank you for any help

We have a custom design using a STM32F373 and USB (USB micro connector). In the past this board has been updated via USB DFU and DFuSe Demo.I am trying to use USB DFU to program the board in STM32CubeProgrammer v2.16, but it appears when the board is plugged into a USB C adapter, it does not correctly identify in Windows 11 64-bit (USB Device Descriptor Request Failed).I've tested this board on 4 different PCs which make me think the USB C adapter and/or Windows 11 is causing the problem:- The board correctly identified on PCs 1 and 2, which had USB A sockets and Windows 10.  Board connected using USB micro to USB A cable.- The board failed to identify on PCs 3 and 4, which had USB C sockets and Windows 11.  Board connected using USB micro to USB A cable, and a USB A to USB C adapter (hub). Is the system memory USB DFU bootloader compatible with USB C/USB 3.0?Are there any known problems using USB A to C adapters with the USB DFU bootloader? Notes on PCB design:- US

Hi Community, I wonder if there is a way to revise a board with new FW upgrade. I am using STM32WB5xx Nucleo board and I did several FW upgrade and I guess I did something wrong in one of the FW upgrade. I have an error saying "Rollback to older version of FW detected.." Is there a way to make my board completely erase and able to FUS? thanks,YJ
