STM32CubeProgrammer (MCUs)

Hello.I'm part of a team and we are developing an BLE application using the STM32WB55 chip.We are using an STM32WB55 chip in our board and we also have the ST_Link interface so we can connect to it. We've tested this interface and used it many times without any issue. Also, we made sure that the connection to the ST_Link is stable and it works.We also have more than 1 ST_Link and all work properly with STM32 chips.An issue appeared while testing the system bootloader, we wanted to perform a full flash erase to reset the chip as factory, but it became unresponsive.When connecting it to the STM32CubeProgrammer, the flash memory cannot be read, and when trying to read FUS version or to interact with it, it fails.Full flash erase shouldn't have done this. What may have caused this?Is there any way to restore the chip to the factory state?It's a custom board and it becomes unusable if this chip doesn't work.

When experimenting with secure boot on the STM32U5A9J-DK, I was following the SBSFU example for the B-U585I-IOT02A board available from STM32CubeU5, but somewhere along the line, I might have bricked it. I can no longer connect to STM32CubeProgrammer or the STLink utility. I get Error: ST-LINK error (DEV_TARGET_NOT_HALTED). I've tried changing the Mode to "Under reset" and "Hot plug" and the Reset mode to "Hardware reset", "Software reset" and "Core reset" (and all of the combinations), but it will not connect successfully. I am using STM32CubeProgrammer v2.19.0 on Windows 11.Is there a way to recover from this situation?

I've just compiled the USB_Example.cpp example and its reporting an initialization error on running (The application could not initialize correctly (0xc000007b)), I have VS 2022 fully updated, I did not migrate the project to the latest toolset to avoid problems.Any ideas STM team? D:\Program Files (x86)\STMicroelectronics\STM32Cube\STM32CubeProgrammer\api\project\Visual Studio\x64\STM32CubePrgAPI\/../../../../lib/STM32CubePrgAPI.exe (process 25224) exited with code -1073741701 (0xc000007b).To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops.Press any key to close this window . . .

I have installed and working Cube programmer v2.13 in a Windows 7 32bits machine. Today, I tried to update it but it threw an error:I tried reinstalling and have the same results. I also tried older versions and the last one that works for me was the v2.15. I update java as well but nothing changes.This means that newer versions will not work on Windows 7 32bits machines?

I'm trying to test writing my own DFU client and I have the simplest of code to start with, see below: #include <CubeProgrammer_API.h> int main() { dfuDeviceInfo* dfuList = nullptr; // Enumerate the available DFU devices int iCount = ::getDfuDeviceList(&dfuList, 0xDF11, 0x0483); if (iCount != 1) { return 0xFFFFFFFF; } int iResult; //#define TRY_VERSION_2 #if defined(TRY_VERSION_2) dfuConnectParameters params; params.usb_index = dfuList[0].usbIndex; params.rdu = 0; params.tzenreg = 0; if ((iResult = ::connectDfuBootloader2(/*m_pDFUDeviceUSBIndex*/params)) != 0) #else if ((iResult = connectDfuBootloader(dfuList[0].usbIndex)) != 0) #endif /* TRY_VERSION_2 */ { ::deleteInterfaceList(); return 0xFFFFFFFF; } ::disconnect(); ::deleteInterfaceList(); return 0; } connectDfuBootloader and connectDfuBootloader2 always return:  /** Operation not supported or unimplemented on this interface */ CUBEPROGRAMMER_ERROR_NOT_SUPPORTED = -5, I'm b

I have a custom board with an STM32H747XI with BOOT0 tied to 0. I want to jump to the bootloader from my application so that I can perform a USB DFU. The USB works correctly. I have a terminal app that I use to connect to the VCP. If I send a specific command, the embedded side will set a variable in a NOINIT section, call USBD_DeInit on the FS and HS devces, then call NVIC_SystemReset. In main before bringing up any hardware, I check the NOINIT variable for the specific pattern, if it is set, I clear it to 0 and then call the JumpToBootloader function from this post: https://community.st.com/t5/stm32-mcus/jump-to-bootloader-from-application-on-stm32h7-devices/ta-p/49510 I've left that code as is. Upon executing, my VCP device goes away and is replaced by a device that is labeled as: Unknown USB Device (Device Descriptor Request Failed) Running wireshark confirms that the descriptor packets are never seen. If I break in with the debugger, it is executing in the area

Hi there, I am hoping this forum will be able to help me:This is my first time using the STM32 Nucleo-64 board (STM32F303RET6) as well as the external ST-LINK/V2 programmer. I just wrote a simple program that turns on the LED but I am having trouble connecting to the board. I am almost positive I have correctly wired the two together (using GND, VDD (3.3V), SWDIO, and SWCLK). I have reinstalled the correct drivers and updated the software. I've tried a few different ways of connecting using recommendations from other forums. These are the errors I've been getting:From stm32cubeIDE:From stm32cubeProgrammer:From stm32 st-link utility:I've tried different frequencies and modes but I still get the same errors. Weirdly, when I try to connect to the target through the utility application, the st-link lights up green and the stm32 board starts flashing (even though it says it can't connect). Is this normal?I just need to know how to successfully connect to the board so I can flash my pro

Hi,I'm using a 2MB flash version of STM32U585x MCU and noticed that when the bank swap bit is set in OB, the wrong page will be erased if I edit flash using the "Memory & file editing". It seems like the page to be erased doesn't take the bank swap bit into consideration.To elaborate a bit: If bank swap is disabled and I edit some memory at e.g. 0x08006000, it will correctly erase page 3 before writing the new data. But if I have bank swap bit set, and edit the memory at 0x08006000 it will still erase page 3 before writing even though it should be erasing page 3+128 since it's this page that is now available at 0x08006000.This had me very confused before I understood what was happening.

Is it possible to securely install firmware over USB on the STM32H743?  I am getting the error below when trying to download my SFI file.  MCU has been powered up with BOOT_0 pin high.  STM32CubeProgrammer finds and connects correctly to chip. 11:03:34 : Starting Firmware Install operation...11:03:34 : Activating security...11:03:34 : Time elapsed during option Bytes configuration: 00:00:00.14511:03:34 : Error: Activating security Failure11:03:34 : OPTION BYTES BANK: 011:03:34 : Read Out Protection:11:03:34 : RDP : 0xAA (Level 0, no protection)11:03:34 : BOR Level:11:03:34 : BOR_LEV : 0x0 (reset level is set to VBOR0)11:03:34 : User Configuration:11:03:34 : IWDG1_SW : 0x1 (Independent watchdog is controlled by software)11:03:34 : IWDG2_SW : 0x1 (Independent watchdog is controlled by software)11:03:34 : NRST_STOP_D1 : 0x1 (STOP mode on Domain 1 is entering without reset)11:03:34 : NRST_STBY_D1 : 0x1 (STANDBY mode on Domain 1 is entering without reset)11:03:34 : FZ_IW

It is possible to enable SWO output with a command like this:STM32_Programmer_CLI.exe -c port=SWD -swv freq=160 portnumber=all swv.log -RAHowever, this is overwriting some of the ITM_TCR flags such as TSENA and SYNCENA (and TXENA), and as such the logfile does not contain any timestamp or sync packets.  It also doesn't appear to be possible to not log to the console, and log to the file only.  I'm really just wanting to dump the raw ITM UART byte stream to a file for later decoding.  Unfortunately, it looks like the tool is also stripping off the port numbers and mangling the uint32_t integers I'm sending, so that the log is mangled completely.Would it be possible to add a "raw" mode to enable the ITM output and log it to a file, without any decoding of the trace?  And allow enabling of options like timestamps and sync packets (or at the very least, not overwriting the register settings for these and just toggle the ITMENA bit?I tried to set this up beforehand:STM32

Hi,I'm looking for an STM32 flashing tool that runs on ARM Linux for use on an embedded board. In our setup, I have a processor and an STM32G491RET microcontroller connected via I2C. Now I need a command-line tool that can run on the processor to flash the MCU over I2C. Is there any tool available that supports this use case?  

Moved from the Feedback forum.The Feedback forum is not for product questions.Hello,I have been trying to update my STM32 using a WinPE image.I created a c++ application that implements the CubeProgrammer_API. The application runs fine, but when I try getDfuDeviceList(&dfuList, 0xdf11, 0x0483), it does not find any DFU device. (Note that the application works well on a normal Windows 11 installation)I tried downloading the STM32Bootloader driver using the C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammerV2.19\Drivers\DFU_Driver\Driver\STM32Bootloader.inf file and pnputil /add-driver STM32Bootloader.inf /install command, but it still does not find the device.I tried listing the usb devices using devcon. It can find the STM32Bootloader USB device and the driver.I also tried using dfu-util, but when I try to list the devices with dfu-util.exe -l, I get "Cannot open DFU device 0483:df11"...Does anyone have any insights on what I am doing wrong or if it is possible at al

Hello, I am currently programming on an STM32WB5MMG microcontroller using Zephyr, and I'm facing an issue with flashing the coprocessor. I am using STM32CubeProgrammer to flash the firmware stm32wb5x_BLE_HCILayer_extended_fw.bin. However, after flashing, the microcontroller gets stuck in Zephyr's bt_enable function, which tries to communicate with the coprocessor. After repeating the flashing process several times, the program sometimes works, but I am unsure why the behavior is inconsistent, even though I am using the exact same procedure. Do you know the cause of this issue, and could you suggest a solution to ensure the flashing procedure works every time?

Hello.Regarding STM32CubeProgrammer CLI, I'm wondering if it is possible to reset an STM32 target only driving (high->low->high) its physical reset pin (NRST of ST-Link V2 connector) and without establishing a logical SWD/JTAG connection with it. Of course NRST of STM32 on my board is routed to NRST of connector and I could issue a reset grounding the latter with a piece of wire.I tried various combination of "-hardRst" but any command without the "-c" switch is refused.Any suggestion?Thank you in advance.Best regards,PT

Hello everyone,I am trying to program an STM32L031F6P6 microcontroller, which is soldered on an adapter and connected to a breadboard.I am using an ST-LINK programmer, and I will attach a picture of the exact ST-LINK I am using. When I connect the ST-LINK to my PC, it is correctly detected by the computer and also by the STM32CubeProgrammer software.However, the programmer does not detect the microcontroller, and I get the error shown in the attached screenshot:"Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication."  Here is how I made the wiring:3.3V and GND from the ST-LINK are connected to VDD and VSS of the STM32L031F6P6.SWCLK from ST-LINK is connected to SWCLK of the microcontroller (PA14 - Pin 20).SWDIO from ST-LINK is connected to SWDIO of the microcontroller (PA13 - Pin 19).RST from ST-LINK is connected to NRST of the microcontroller (Pin 4), with a 10kΩ pull-up resistor to VDD.BOOT0 pin

Hello,I am currently working on a project involving the STM32L031F6P6 microcontroller, and I would like to ask a few technical questions:What are the basic settings required to initialize and get this microcontroller up and running?How can I properly connect it to an ST-LINK for programming? Are there specific pins that must be used?Are there any general technical tips that could help me get started with this STM32 model?Are there any important notes regarding power supply or protection of the surrounding circuitry?Any guidance, technical documents, or advice from experienced users would be greatly appreciated.Thank you very much in advance.

My company wishes to implement a feature in an existing C# application in order to download firmware to MCUs (USB DFU only).I was able to get this done using the drivers and dlls provided through Dfuse (https://www.st.com/en/development-tools/stsw-stm32080.html).There seems to be an issue concering the Dfuse driver on some of our computers which is why I tried to do the same using the driver and the CubeProgrammer_API.dll which are both part of the STM32CubeProgrammer (https://www.st.com/en/development-tools/stm32cubeprog.html). I managed to get that working as well, but it seems like the CubeProgrammer_API.dll needs a lot of other files to be able to work (>400MB).This is why I was wondering if the CubeProgrammer_API.dll accesses another separat dll that only handles the USB DFU protocol (like STDFU.dll which is part of Dfuse) and does not need the >400MB of files.Best,Stefan 

  Hello,There seems to be a bug in Stm32CubeProgrammer v2.19.0I connect the STM32F767 with USB1 (DFU).When I press the CONNECT button, the connection stops at  44 bytes.the connection is "Not connected"however, I can now download a program.

So I know if I use the STM32CubeProgrammer there's an option to skip flash erase before programming which is great. However, I'm trying to debug some code and I need to prevent flash erase, because I have some code in a sector which I need to keep, but also program some new code in that same sector.By using the 'ST-LINK_gdbserver --help' command, there's no option/argument which I can use to prevent the flash erase before programming. I tried using the '--skipErase' option mentioned here:https://community.st.com/t5/stm32cubeprogrammer-mcus/skipping-flash-erase-with-stm32-programmer-cli-and-stlink-v3/td-p/608809  But it didn't work for me:'/opt/ST/STM32CubeCLT_1.18.0/STLink-gdb-server/bin/ST-LINK_gdbserver -p 50000 -cp /opt/ST/STM32CubeCLT_1.18.0/STM32CubeProgrammer/bin --swd --halt --skipErase -m 0PARSE ERROR: Argument: --skipEraseCouldn't find match for argument' It seems like the --skipErase command is specific for the programmer, but there's no way to invoke it from t
