STM32CubeProgrammer (MCUs)

STM32CubeProgrammer version 2.16.0Target STM32G0B0RET6, device ID 0x467, Rev Z, 512KB flash, bootloader 0xD0When loading a large bin file (425kB), the programmer tries to erase 65364 sectors! There's only 256 sectors in target, and the image only needs 212 sectors erased.When using an ST-Link SWD interface it gets past this (albeit erasing entire flash) and programs the flash OK, but when using USB it just locks up.It doesn't happen with smaller files that will fit in bank 1, just larger files that require 2 banks.If I do a full chip erase first, then tick "skip flash erase before prog" then it avoids this problem. However I need to preserve config data at top of flash, so this is not a good workaround.I think it's a similar problem to this post so I replied to that, then thought I should start a separate thread.Here's some basic logs in case it helps.

I ran system bootloader, I can perform the bootloader process using the STM32CubeProgrammer software via USART. But what I want is to run the bootloader software over TCP or UDP using the USART protocol. Because my UART2 line is connected to a TCP converter.I wrote a piece of code using Python, but it's very slow and disconnects after a while. Is it possible to enable STM32CubeProgrammer to communicate with UART protocol over TCP?Softwareally, I used TCP to Uart converters, but STM32CubeRogrammer is getting a time delay error.My system is as follows;

HelloI'm using STM32429I-EVAL1 and its touchscreen is not working.When I plug st-link cable, originally touchscreen was initialized and displayed menu.But now, it only displays totally white screen and there is no reaction when I touch it.I did Software Reset and Hardware Reset with STM32CubeProgrammer, but is it effect to touchscreen?How can I solve this?

Hello,I have installed STM32CubeProgrammer (version 2.14.0) on a Linux machine. I have connected my NUCLEO-U575ZI-Q microcontroller to the machine, but the CubeProgrammer does not detect it (the machine does). I received this message on the CubeProgrammer:ST-LINK error (DEV_CONNECT_ERR)I tried the same setup on a Windows PC and it worked perfectly (with the same version of CubeProgrammer).What could be the possible solution?Best regards,

I want to write firmware to stm32u575 using cube programmer, but when I do download from the erase & programming section, it fails to write.Of course, I have turned off the "skip flash erase before programming" checkbox.However, if I run the program in automatic mode with the "full chip erase" checkbox checked, it writes successfully.With the L4 and G4 that I have used in the past, I was able to write successfully in both cases, but with the U5, it fails.When I use the U5, I use cube programmer.dll to perform full chip erase before downloading.,Has this behavior changed since the writing of u5 microcontrollers in the specifications?I have confirmed that the option byte is factory default. 

STM32_Programmer_CLI fails to list UARTs unless an STLinkV2 is also connected to a USB port (not even to any target).  If an STLink is connected, the UARTs are then listed!  Disconnect the STLinkV2 and the UARTs fail to list.  So the issue appears to be a bug in 2.16.  Note: I have tried with both -l and -l uartSeparate issue: none of my STLinkV3s enumerate in the STLink Probes list. You can see an MINIE in the UART list below at COM14. I suspect I need to update the driver, but the driver download link on the ST site is currently broken.  <sigh>. C:\Users\david>"C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -l ------------------------------------------------------------------- STM32CubeProgrammer v2.16.0 ------------------------------------------------------------------- ===== DFU Interface ===== No STM32 device in DFU mode connected ===== J-Link Interface ===== Error: No J-link probe detect

I executed this command : STM32_Programmer_CLI.exe -c port=SWD sn=xxxxxxxxx232xxxxxxxxxxxx and got the response that gave me details about the device, but not COM Port. Is there any command that gives me the COM Port number to which my device is connected ? I know about the "-l uart" command. any other command than that ? Thanks in advance. 

I am using the cube programmer API in a Qt C++ windows application and hit a problem where there is clash in naming of the disconnect() function. disconnect() is in both qobject.h and CubeProgrammer_API.hI am not a C++ expert, so please tell me if I have something wrong, however my understanding is that I would normally deal with this using namespaces. However I see no namespace defined in CubeProgrammer_API.h.I have worked around this by modifying CubeProgrammer_API.h to include a namespace. eg #ifndef CUBEPROGRAMMER_API_H #define CUBEPROGRAMMER_API_H namespace CubeProgAPI { #ifdef __cplusplus extern "C" { #endif . . . #ifdef __cplusplus } #endif } This allow me to call the functions using the namespace ( eg  CubeProgAPI::disconnect(); ) and it does build without error but my understanding is that is not correct as the CubeProgrammer_API.lib I am linking against does not have the namespace. In fact I don't understand why it doesn't failed to link as I am

Hi,I have a STM32HSM-V2AE and I tried to follow de "SFI Step-by-step on STM32 boards". In the part of "HSM programming" I connect the STM32HSM-V2AE to the computer with the smart card reader ACS ACR39U-UF but I have the following error:Error: HSM initialization error 0x88000002 What I have to do to continue from this step onwards?Greetings and thanks in advance.

Hello all, I am currently developing on the STM32H563ZI and encountered an issue where, when swapping to Bank 2 to erase/write flash, it simultaneously erases the same address in Bank 1. Here are the steps I followed: Swapped to Bank 2. Used STM Programmer 2.16.0 to flash a bin file to the address 0x8100000. Used STM Programmer 2.16.0 again to flash the same bin file to the address 0x8000000. At this point, the code initially flashed to 0x8100000 was erased. Subsequent tests with writing only a few bytes also resulted in the same situation. Are there any settings I can adjust to avoid this situation? Thank you very much!

If driver porting is successful, reading and writing eMMC from STM32CubeProgrammer should be feasible.I have tested that the read, write eMMC functions are ok and implemented in read, write, MassErase and SectorErase functions of Loader , but from the STM32CubeProgrammer it always fails.Can anyone help me?MCU: STM32H743BIT6eMMC: ISSI IS21ES08G-JQLI

Hey everyone,I was writing a 'How-To' for flashing an STM32F04 while I stumbled upon this phenomeon.After program&verify I read back the device memory and compared it to the file I downloaded.I then get the message 'Warning: difference found at 0x8000000" but the first and only difference that is marked is at 0x8007090 I then tried it with the ST Link Utility Tool and compared the device memory (without programming again, so still the download from the CubeProgrammer) with the result that the files are identical.If I read back the device memory with the CubeProgrammer, save it, download it and compare again they are also identical so it doesn't seem to be a general downloading problem.But for some reason my original .hex file seems to cause issues, but only with the Programmer and not with the Utility Tool. Am I missing some kind of setting here? Or what could be the issue?  Thanks in advance,Sammy

Hi,I am conducting tests with the HSM and SFI. I have tried the use case of attempting to install an SFI with an HSM that uses other keys. Obviously, I couldn't do it, but now I cannot connect the microcontroller in "normal" mode. If I connect it in "Hot plug" mode and try to change the RDP, it shows the following message:Enabling RDP when TrustZone is active!If no valid secure code booting and calling non-secure code, it may prevent disabling TrustZone And RDP.And if I click OK, it shows the following message:Your device may be lost FOREVERWhat should I do to fix this error so that I can reconnect the microcontroller to the STM32CubeProgrammer?Best regards,

Hi Everybody, I try to flash my firmware into NUCLEO-STM32F410CBT6,  first, I didn't remove CN2 Jumpers for nucleo ST-link V2. and then, select nucelo board in cube32Programmer after that, click connect button, it works well. but, I want to flash program to use ST-Link V2, not nucleo board.In the datasheet for ST-link V2, 2x10 20pin connector. To use JTag or SWD flash, at lease VDD, JTMS, JTCK, GND, JTDO, NRST are need.  So, I connect wire to St-link V2 pin to Nucleo Board, it is not work.  How can I do that? Thanks     

During the installation of the STM32CubeProgrammer creates some registry keys under:HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\STM32CubeProgrammer 2.16.0\One of them is "UninstallString" with the value:cmd /c start /min cmd /c "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Uninstaller\unscript.bat" & "C:\Users\elkadmin\AppData\Local\Temp\7zS852D4102\jre\bin\javaw.exe" -jar "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Uninstaller\uninstaller.jar" -f -xIf I run this command on in a cmd.exe with the same elevated credentials as the installer was started I get the initial uninstall screen as expectedAfter clicking on the "Uninstall" button I get the unhandled exception message:Here is a text version:exception caught com.izforge.izpack.api.exception.WrappedNativeLibException: NativeLibException.functionFailed.RegOpenKeyEx NativeLibException.libInternal.OsErrNumPraefix5 NativeLibException.libInternal.OsErrStringPraefixAccess is deni

I am running into an issue with the latest release of the STM32CubeProgrammer.It seems that, at least for STM32F030 MCUs, it is unable to program option bytes. A similar error has been reported earlier (see this topic).The same error is present when I use STM32CubePorgrammer CLI, version 2.15.If I downgrade to version 2.10, the error goes away and I am able to program option bytes normally.

Hello,I'm currently working with the STM32G474RE microcontroller and aiming to transition from the standard dual bank mode to the single bank mode.However, I've encountered an issue during this transition. When switching the bank mode, the read width changes from 64 bits to 128 bits. This change in read width is leading to data misalignment problems so when  the HAL launch function responsible for loading and resetting the option byte after the bank mode switch is called, the program seems to hang, suggesting possible damage.Could you please provide guidance on how to address these issues and ensure a smooth transition to single bank mode without causing data misalignment or program damage?Thank you for your assistance. 

Hi.I wanted to know if the -w32 command always performs a sector erase?Does the -w64 command always perform a sector erase? If they always delete the sector, is there a command that doesn't do it?Best regardsJk 

Hello,I will configure the boot mode in the option bytes of the STM32G030F6. Now I see only the nBOOT1. I missing the nBOOT_SEL and nBOOT0.In the refernce manual are describe all:How can I cinfigure it?And after the programming I will reload the option bytes with setting of the OP_LAUNCH flag. Can I do it with the STM32Programmer and how?Thanks for our help,Bernd

Hi Everyone,I want to know Is any possible way available so I can upload firmware for my custom stm32 board using Command Line Interface? ST providing any Command Line Interface and commands?Unfortunately, I could not find ST Cube Programmer CLI. I can use ST cube programmer GUI but I want CLI.I have 2 custom boards. I want to upload firmware for both devices using CLI. My controller is STM32G family and STM32H family. Thanks in advance
