STM32CubeProgrammer (MCUs)

Hello All,I am sort of new to STM32 programming, so I got confused with bootloader operation.I am using STM32G0 series MCU. Currently I am working on a functionality to program firmware using UART. As a part of this task I am playing with the option bytes. I noticed the following: If I connect to the board using ST-Link then the option bytes have different value than if I connect using UART. Moreover, if I change option bytes in ST-Link I cannot notice those changes if I then disconnect and connect with UART. And vice versa - changing anything while connected via UART is not seen if the OPB are then read from ST-Link. Additionally it seems that only changes made via ST-Link have real effect. What I mean is that if we are in a bootloader (nBOOT_SEL = 1, nBOOT1 = 1, nBOOT0=0) then rewriting nBOOT0=1 using ST-Link has an effect and the board starts normally. However if same is done via UART then nothing changes. It looks like we are still hanging in a bootloader.What is funny is that

Hello, I am trying to use STM32CubeProgrammer with a J Link interface to program a STM32G473 MCU.But CubeProgrammer seems to be stuck while programming.I can read the MCU flash, erase it, but not program.I tried with another MCU (STM32G0B1) and it works with that one.But I can't with G473...I am using the latest CubeProgrammer version 2.17.0 for Windows 64-bit and the latest J Link tools (8.10).Is there a bug in CubeProgrammer? Do I need to do something more to program a G473? Thanks for your help

Hi,We are using STM32_Programmer_CLI on windows and linux.I noticed that since version 2.16 following commands fails:STM32_Programmer_CLI -c port=SWD freq=8000 sn=x mode=UR -e ed1 & ed2with:Error: The erase command you trying to perform is missing some arguments. Please refer to the Help to see how to use it. It worked fine on version 2.15. I've looked into any api changes for newer version in release notes but I couldn't find any relevant changes that could affect this behavior. For me, it looks like this is potential bug/regression. Let me know if me guess is correct or we need to adjust params added to command.Thx

1. I have encountered a problem when trying to use B-U585I-IOT02A board with the default external loader available in stm32cubeprogrammer (M25LM51245G_STM32U585I-IOT02A). There is an error when trying to read, or write external flash memory, but erase seems to work fine. I am attaching the error screenshot.From my program (FW - not external loader) external flash works well. What could I have done wrong? It seems very simple, however, it doesn't work as per the instructions and tutorials.2. Is there any good instruction on how to build an EWARM example project into a .stldr file without an IAR?  

I'm using V.2.16.0 to set the option bytes for the STM32G031, but NRST_MODE and IRHEN are not showing in the OB section.There is a report for the same issue for the STM32G030 with the accepted solution being that the G030 does not officially support these options. However, that is not the case for the G031 as the options are documented in §3.7.8 of the reference manual.

STM32CubeProgrammer version 2.17.0Target STM32G491, device ID 0x0479, 512KB flashWhen loading a large hex file (284kB), the programmer tries to erase 65293 sectors!  There's only 256 sectors in target, and the image only needs 141 sectors erased.We also use the internal flash to storage some settings of the device. These settings are erased when using version 2.17. We tried this earlier with version 2.13 and no problem was detected. See attached log files of both version 2.13 and 2.17 Please provide help.Thanks, EG

Hi,When installing STM32CubeProgrammer on a Linux machine with a graphical interface, an installation window appears. Now, I want to install STM32CubeProgrammer on a Linux machine without a graphical interface. When I run the installer, I get this error message:Command line arguments:SEVERE: com.izforge.izpack.api.exception.IzPackException: Console implementation not found for panel: com.st.CustomPanels.AnalyticsPanels How can I install STM32CubeProgrammer without the need for a graphical interface?Best regards,

Hello everyone,I'm encountering an issue while using an external loader to program an external flash memory (MX25L6433F) on an STM32H563IGK6 board. My objective is to access this external flash (OCTOSPI1) with DFU for operations like erasing, writing, and reading, specifically to download my application into the external flash.However, when I run the command using STM32CubeProgrammer via the command line, the program loads a bootloader named "STM32H7RS-DK" instead of using my custom bootloader, which is already running on the board.I have a few questions regarding this behavior:Why does STM32CubeProgrammer choose to load this "STM32H7RS-DK" bootloader? I understand it is a secure bootloader, but I'm unclear on why it's being selected.Does this mean my custom bootloader will be ignored or replaced?What exactly does this choice of bootloader by the program mean, and how can I access my external flash (erase, write, read) while still using my own bootloader?I've attached a screenshot for

The text printed to console after running "STM32_Programmer_CLI --version" stays in bold To reproduce :STM32_Programmer_CLI --version && echo "This shouldn't be in bold" The output:        -------------------------------------------------------------------                     STM32CubeProgrammer v2.16.0        -------------------------------------------------------------------STM32CubeProgrammer version: 2.16.0This shouldn't be in bold 

The new version 2.17 of STM32CubeProgrammer feels a bit glitchy.It appears something is queuing or delaying messageboxes, such that a lot of messageboxes appear after it finally succeeds with something. Or it can start many operations in the background. Something is off. But most importantly: it does not erase lock bits properly of the STM32F407Eventually it does something. But throws a lot of messageboxes on the way.Is this known?

I'm trying to use the STM32CubeProgrammer with the newly supported J-Link settings, but can't seem to get it to work.I'm using:STM32CubeProgrammer: v2.17.0STM32H573I-DKSEGGER J-Link PLUS: SEGGER J-Link Commander V8.10c (Compiled Oct 16 2024 16:20:30)I have set the External Debug jumper JP1, and have connected my SEGGER to the DK. I can connect to the DK via the SEGGER using JLinkExe, can debug using JLinkGDBServer, etc. JP4 is set to USB-PD, and I have a usb cable plugged into CN17.I'm trying to connect to the board using the STM32CubeProgrammer, but am running into issues.

Hi,I am trying to connect to a STM32H523RET MCU via SWD using a J-link Debugger (CubeProgrammer v2.17.0).Reading the Product ID fails, so I get asked to select the MCU manually.Unfortunately the list does not contain any STM32H52x MCU But when I am trying to connect via Jlink - Commander I can find der MCU in the list and also connect to it:Does anybody have an idea, why I can't find the MCU in the list when using the CubeProgrammer?Thanks for any hints.RegardsJohn

Hi, I hope someone can help me with this.I am using STM32CubeProgrammer 2.16.0 with an NUCLEO-H563ZI and Ubuntu 23.10. Programming, reading Registers seems to work. STM32CubeProg halts or runs my running or halted MCU approx every second depending on the mode Setting of the ST-LINK, no matter what state the MCU was before.The Problem happens with the already preinstalled SW or my own SW. ST-Link Firmwareversion on the NUCLEO Board got updated to V3j13M4  With mode HOTPLUG it halts, reads PC, and continues execution. Independent whether the CPU was halted or running before.with mode NORMAL it halts the core and reads PC, after that leaves the MCU halted, Independent whether the CPU was halted or running before. When i set Verbosity level to 3 i get following log:01:22:23:952 : r ap 1 @0x40022050 0x00000004 bytes Data 0x2D30EDF801:22:23:952 : r ap 1 @0x40022070 0x00000004 bytes Data 0xC300017C01:22:23:952 : r ap 1 @0x40022050 0x00000004 bytes Data 0x2D30EDF801:22

Hi,is it generally possible to program/read/erase an external connected Flash-Memory (e.g. Quad-SPI-Flash) with STM32CubeProgrammer via USART bootloader? I'm using the STM32L496-DISCO board for test.External loader MX25R6435F_STM32L496-DISCO selectedBOOT0 connected to VddCOM1-RX/TX/GND (3.3 V level) connected to MCU USART3 bootloader pins PC10/PC11/GND With upper configuration MCU-Flash program/read/erase is possible, but no access to Quad-SPI-Flash (address = 0x90000000), see picture. With selected ST-LINK probe access to Quad-SPI-Flash is possible. Thanks in advance,Karsten 

The desktop entry icon is not showing, and the Cube Programmer crashes as soon as it is launched on Fedora 41. It works fine on Fedora 40. Note: sometimes it works, and I ran some tests which were fine.Please help me, as I need to study. These issues with the app are frustrating and damaging my brain, making it hard to focus.

Just startet my small modbus therrmocouple project and im facing the issue with STM32G071CBU6.       First of all im not abble to connect via DFU usb, device isnt recognize i try reinstal stmCubeProgrammer, didnt change anything. Then try install drivers too device manualy, windows claims that best drivers are installed.       Second, im abble to connect via UART and put bin inside but the problem is im abble to do it only once (tried 2 IC's), after that programms run OK but device isn't visible via UART anymore. What's weird is that chip doesn't react to BOOT0 (PA14) state change's. Low is boot from flash, high from bootloader. No matter if its high or low, or even floating programm is running. The only way to erase chip is connecting via STLink, than UART works again untill next bin being write. Anybody face simmiliar issue?Schematic in attached.
