STM32CubeProgrammer (MCUs)

Hi everyone, History:I am running from bank 0 and I start an upgrade after the upgrade I do a bank swap and the application starts running from bank 1.Problems:Now I use a debugger to flash the .elf file in the micro-controller. But the code does not boot up. I open stm32 programmer uncheck the swap bank and re-flash the code and then the code runs.What I want:I want to uncheck the swap bank flag so that I am always in bank 0 when I flash my binary on the µC. I need to do it because I want to connect it in a CI/CD pipeline and I dont want the system to break.I want a script that ideally works jlink.exe to reset only the swap bank bit and not touch any other bit in the registerMy .jlink script:device STM32H573AI si SWD speed 4000 connect // Step 1: Check FLASH_SECSR for BSY, DBNE, WBNE bits (manual step, not supported in .jlink script) // Step 2: Clear error flags in FLASH_SECCR w4 0x4002202C, 0xFFFFFFFF // Step 3: Unlock FLASH and OPTION BYTES w4 0x40022008, 0x45670123 w4 0x4002

Working with CubeProgrammer connected to a Nucleo-G0B1RE board, a binary file needs to be stored starting from address 0x0800_C000 on the chip.  However, when the `Start Programming` is initiated, the process fails immediately as can be seen in the attached image.  The source file to be flashed is also attached as an archive.If the start address is changed to 0x0803_E000, then the download process says it completes.  All option bytes are at whatever the factory default is for this board.

Hi allFor the STM32U5, the reference manual shows the GCCFG register as but STM32CUBEIDE showsbit 16(and a lot of other bits) are differing. Is this an error and if so which is the right one 

I've just bought this board: https://www.st.com/en/evaluation-tools/nucleo-f767zi.html and when I start programming the board using STM32CubeIDE, I've run into this error: So I've searched how to fix it, I've used STM32CubeProgrammer to do a full-chip erase, but still failed:So what should I do next to make this new kit work? 

The CLI works fine on Windows 10 but on a Windows 11 computer I get this output:Unlock SuccessPatched SREC with unique IDSTM32 ST-LINK CLI v3.6.0.0STM32 ST-LINK Command Line InterfaceST-LINK SN: 62021102220032524B413836ST-LINK Firmware version: V2J37S7Connected via SWD.SWD Frequency = 4000K.Target voltage = 3.3 VConnection mode: NormalReset mode: Hardware resetDevice ID: 0x418Device flash Size: 128 KbytesDevice family: STM32F10xx Connectivity LineLoading file...Unable to open file! It would be really helpful if the error message gave the path of the file it can't open.

Hello everyone, and thank you in advance for your kind assistance.We've noticed a discrepancy between the datasheet and STM32CubeProgrammer for the STM32U073RCT6 device.In the datasheet (DS14548 - Rev 2, page 45), the threshold specified for VBOR0 is 1.7 V.When connecting to the board with STM32CubeProgrammer v. 2.19.0, the GUI indicates that the minimum selectable value is 2.0 V (option bytes).Can you please confirm:If VBOR0 = 1.7 V, is this the guaranteed value (typ/min/max as indicated in the datasheet) for this OPN?If there is a known restriction with CubeProgrammer or ST-Link that prevents the selection of VBOR < 2.0 V for this device?If there is an errata/note that changes these values?Thank you all for your kind attention.

I am using an ST-link / V2 as the debugger and the microcontroller I am using is STM32l031k6u6. I am trying to debug and download a program into the microcontroller but I am facing this error. I have tried to debug and download using IAR embedded workbench as well but to no avail. I would be obliged if anyone can help me out. I did connect the VDD, GND, NRST, SWCLK, SWDIO pins correctly.   

Hello,I am new to FW/EE design for one of my board that has a STM32G0B1CEU6N. I got the board from our CM that has wifi modules and a battery connected to the PCB board which has the above mentioned STM.  What i would like to understand is how to communicate with the board for flashing the new FW/SW. The board has a 2X2 (pin header) that has the SWDIO, SWCLK, NRST and GND.  Can this pin be connected to ST-LINKV2 to talk via USB from WIndows. I also have STM32CUbeprogrammer installed. I tried connecting it the way as mentioned above but it does not detect. What could be the issue here?

Hi. is any one facing issue like mine.  After updating STM32CUBEPROGRAMMER TO V2.20 external loader giving error at erasing external memory. when i download the code in controller having external qspi flash, it is showing error "failed to erase chip".  screenshot is attached. If i perform Full CHIP Erase. I am able to erase the chip. ever single sector is erased. but my code uses 111 sectors of external memory which is failing to ease. same issue is giving at cubeide 1.19.0. before updating everything was working. i upadated IDE and it failed to erase the chip. but my old cube programmer was doing job. when i updated cube programmer, it also stopped erasing external memory 111 sectors.

Hello,I'm encountering a connection error with STM32CubeProgrammer when trying to connect to my NUCLEO-H7A3ZI-Q board.**Error Details:**- Error: "No STM32 target found!

Is the 1.22V voltage reading normal, or could this indicate a power issue?Any help would be greatly appreciated!Best regards

Hi,I have a custom board that duplicates the STM32N6 Disco schematic for an external flash MX66UW1G45G. I configured  the .ioc to configure XSPI2 and XPSIM with PN6 pin for the clk. I use STM32CubeProgrammer with the external loader activated for MX66UW1G45G. The CubeProgrammer connects via a J-Link cable, and I select the first few blocks to erase. When I click Erase Selection, the oscope shows activity on XSPIM_P2_IO0 and XSPIM_P2_IO3, but nothing on the clock. I also didn't see any activity on the NCS1, it remains high. The Clock Configuration tab in the .ioc file shows an active 66.66MHz clock signal to XSPI2, with HCLK as a source.The .ioc has XSPI2 and XSPIM enabled for all three domains - FSBL, Application, and ExtMemLoader. I attached the .ioc. Huge thanks for help!  

When i enter the programmer I get a signal to upgrade to v2.20.The process of downloading appears to be proceeding ok but at the end the program just shuts down. When I rerun again the v2.18 comes up and the system asks me to upgrade again to 2.20.

I have a NUCLEO-H7S3L8 board, and I am unable to debug any of the projects. I receive a sigtrap error upon debugging. I have tried multiple projects in ST's Github. STM32CubeH7RS/Projects/NUCLEO-H7S3L8 at main · STMicroelectronics/STM32CubeH7RSAll projects have the same issue.After further investigation, we have determined that the default start address for the application is incorrect. If I make a fresh project and select the chip itself rather than the eval board during project setup, I am able to debug.Is this a known issue with this NUCLEO board?Is there a way to change the address so we can explore the example projects?Is there an alternative NUCLEO board that is not in the R/S family that I should explore instead?Thanks 

Hi, we have issues with USB DFU where we use the PC port. I uploaded two log files: one from CubeProgrammer and one from USB log in .txt (Wireshark).Depended the on the USB port I am using USB DFU works.

Hello all,I am a newbee, and so far I finally did successfully in creating my first prog with STM32CubeIde.I am able to produce .bin, .elf, .hex files for my project with CubeIdeI am able to read and produce a bin file of the program in flash in my board with the CubeProgWhen I want to flash back to the board using DFU mode, I noticed that bin file doesn t have any segment starting address, elf file instead, have a starting address 0x800000If I load a bin file, do I have to specify the correct programmer address I mean 0x800000 in cubeprog, because it doesn't itself :( 

Hey all,I wanted to check if there’s a way to program multiple PCBAs in parallel using multiple ST-Links. I have 6 PCBAs and 6 ST-Links, but since we currently have only one DLL, we can target only one ST-Link at a time, this makes the overall programming process quite time-consuming.If anyone has a solution or any suggestions, please let me know. Your help would be greatly appreciated.Thanks and regards,Lakshya

While fiddling with H745 board to investigate how dual core works, after modifying option byte to BOOT_CM7 = 0 and BOOT_CM4, STM32CubeProgrammer (nor STLINK-gdbserver) refuses to connect to the board with "Error: No STM32 target found". The ST-Link itself is okay. Here is a log from the programmer.22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : No STM32 target found! 22:31:39 : ST-LINK SN : 002F003D3137510E39383538 22:31:39 : ST-LINK FW : V3J5M2 22:31:39 : Voltage : 3.30V 22:31:39 : Error: No STM32 target found!How do I regain access to the board?

Maybe I need to install the appropriate font? (Version 2.19-2.20)

When I try to install the CubeProgrammer, I get the following error message:“SetupSTM32CubeProgrammer-2.19.0” is damaged and can’t be opened. You should move it to the Trash.I get the same error message when I unzip and double click in the finder or use the terminal with zsh or bash.  I also tried version 2-18 and 2-17 with the same result.I have successfully install CubeIDE and CubeMX.

why v2 stlink (stm32h7 series original Nucleo Board  ) + cupeProgrammer not connecting with w25q128 flash(external loader) .  external loader not working since from cube ide v18.0.0 has been released and recent version V19.0.0 having cubeMx qspi enable itself .I was fine  with qspi +cube ide v17.0.0  and qspi+cube programmer + CLIVEONE stldr.Even i have downgraded the cube ide again to v 17.0.0 and below version  the same work i carried out for cube programmer as well but nothing worked out .this is problem of v2 stlink driver or something else ? .  

Hello,I'm experiencing some hard unstabilities navigating in stm32cubeprogrammer 2.20.0 UI on an up to date debian trixie system. Even without being connected to programmer, attempting to start tool in production programming mode frequently leads to crash, making tool unreliable. Once programming starts and no UI interaction is done, tool keeps running, but attempt to start/stop usually lead to crash.Command line programming tool without any issue on that system.We're using stlink v3mods module with up to date firmware - that project is based on stm32f412re but issue occurs even without mcu connected.$ /home/xyz/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32CubeProgrammerLoading PRG Library: /home/xyz/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/../lib/libCubeProgrammer_API.so[Analytics] No requests are done with CLI100 external Loader listServer certificate verification succeedServer certificate verification succeedServer certificate verification succeedServer cert

I have many thousand devices which need to be reprogrammed which are already have RDP set to 0xBB.  The Automatic Programming Mode works wonderfully well for devices which are at RDP=0xAA but the programmer fails when reprograming 0xBB parts in an automatic way.(Please do not confuse my question with setting RDP AFTER programming.  My problem is re-programming parts already in a state of RDP=0xBB.)The non-automatic mode works as expected by first setting the option bytes (which triggers the internal chip erase) and secondly to reprogram, but this is not a useful solution for the number of parts needing to be reflashed.In automatic mode the tools expected operation is to set any non-RDP=0xAA value to 0xAA, wait for the internal chip erase to occur and then download the data to the device.  This step appears to be missing from the gui code.Pasted below are the annotated log files for both failed automatic attempts and successful manual attempts.I am using STM32CubeProgramm
