STM32CubeProgrammer (MCUs)

I am using the following command  ./STM32_Programmer_CLI --connect port=/dev/cu.usbmodem103 P=none  but I get the following error:Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... However, if I add "console" at the end of the above command I can connect and I can write/send files but i cannot read. How to fix that? 

I have detected a problem with the v2.15.0 (64 bits) when flashing a STM32L475 MCU.The message 'sector nnn does not exist' appears repeatdly when erasing sectors when flashing the device.This only happens with v2.15.0., and then the device last a lot to be flashed and if there were some preserved flash areas, they are erased Nevertheless, if v2.14.0 is used, the update procedure is completely carried out.So, which is the problem? Is this issue already identified?  

I am trying to modify the NRST_MODE option byte for a STM32G030 MCU.I have changed the reset pin to GPIO using the GUI, but that is not very usefull for a production environment.The option byte in not available from the CLI. -> Please make it available (very usefull for production programming)On the GUI the option is hidden away in the Registers - BETA page -> FLASHPlease make it available on the option bytes page for the STM32G030For the STM32G031 it is there in the Option Bytes -> please make it also available for the STM32G030. Also the CLI has the NRST_MODE as an option byteBeste regards, Hans.

I have tested few of the stm boards like STM32F302R8 , STM NUCLEO f767zi .We connect the hardware to laptop and usb pass through on VMware allows it to detect on virtual com port of VDI.But when we try to access the stm hardware through stmcube programmer, under serial number it shows " not st link available" STM hardware devices are detected on virtual com ports on the VDI but not on the cubemx programmer. Can anyone help me on this

Hello Everyone, II'm currently working with my Nucleo L073RZ board and so far my program built successfully but i cant upload it. Nonetheless, other programs are still able to run well on the board. I dont understand what i am doing wrong. I have read other responses to similar questions but i still cant find a solution. Please I will be glad to get some help/ideas on how to solve this. Thank you.Best Regards!STMicroelectronics ST-LINK GDB server. Version 6.0.0Copyright (c) 2021, STMicroelectronics.

Hi :)Problem: STM32F030R8T6 device not found.ErrorMsg in CubeProgrammer: "No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication."ErrorMsg in CubeIde: "Error in initializing ST-LINK device. Reason: No device found on target."Setup: I made a breakout-board for an STM32F030R8T6. The board only carries the µC and spreads out the pins to use on a breadboard. I connected all VSS and VDD pins and used 0.1µF capacitors as close as possible to the µC. I connected the ST-Link-V2 as follows:VSS -> any GND pinVDD -> any 3V3 pinNRST -> NRST  (pin 7) (not sure if I need to connect the pin somehow aside from the debugger)SWDIO -> SWDIO (pin 46) 220Ohm PullupSWCLK -> SWCLK (pin 49) 220Ohm PulldownI tried BOOT0 pin pulled low or high, both didn't work.I double and tripple checked my connections. I am using the right pins on both sides and the µC has power.  -------------------------------------------------

I am using CubeProgrammer_API to implement a firmware update on my app. I am encountering an error where it cannot connect to the DFU bootloader. The device is visible in device manager and it is properly connected.int usbConnectFlag = connectDfuBootloader(dfuList[0].usbIndex); This line is causing me issues as it is not printing any values. Any code below this line would not run. I am not sure what is the issue.

I'm using a working + tested board with the STM32H503KB; connecting over SWD via an ST-Link board. I'm on MacOS and using version 2.16 of STM32CubeProgrammer.I am attempting to use the programmer to write a SHA256 password hash to OTP memory, in order to configure debug authentication. Without this, I cannot progress the product state to Provisioning or higher without losing device access. I am finding I am unable to perform this through either the GUI or CLI.First, I'll describe what happens in the GUI. I successfully connect to my target, enter the Secure Programming section, and click the PROV tab. I enter a password, choose an existing directory for the password file to be saved, and click Start Provisioning. Here is a screenshot just before I click the button.When I click Start Provisioning, the window instantly closes; no error dialog is shown.When running the application from the terminal, executing /Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubePro

Hello, I tried to install STM32CubeProgrammer 2.16.0. But getting this error message. How to fix this? Thank You!

Using the STM32CubeProgramer (v2.16 from a Windows 11 laptop) with my NUCLEO-U575ZI-Q board has, from this morning, resulted in only the response:UR connection mode is defined with the HWrst reset modeST-LINK SN : 003E004C3532510F31333430ST-LINK FW : V3J13M4Board : NUCLEO-U575ZI-QVoltage : 3.29VError: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug AuthenticationLooking at the various posts here about fixing programming issues, I have tried setting STM32CubeProgrammer to "Under reset" mode and holding the RESET pin down from power-on while I attempt to connect, but all that does is get me a different failure message:UR connection mode is defined with the HWrst reset modeST-LINK SN : 003E004C3532510F31333430ST-LINK FW : V3J13M4Board : NUCLEO-U575ZI-QVoltage : 3.29VError: ST-LINK error (DEV_TARGET_HELD_UNDER_RESET)I have also tried the same procedure but allowing the board to power on first and only then holding reset and trying

I am using C# to wrap the native CubeProgrammer_API.dll to call download file. I am running on x64 machine.When I compile the C# code as x86 and use the x86 version of the DLLs from the SDK, the download went fine.However if I compile the same code as x64 and use the x64 version of the DLLs from the SDK, I am getting a -10 from the downloadfile.Does anyone know a reason for this puzzling behavior?Thanks.

I recently got into dual core mcu (STM32H755ZI) programming and made the common mistake of not configuring the cores correctly and now the board would not connect (I used the STM32CubeProgrammer to flash one of the two .hex files into the device memory). I have tried the suggested process by Adam BERLINGER on the forum but for some reason it did not work and after hours of trying the same thing over and over I found that the following process works for me.1. Connect the NRST pin to GND2. Connect the board to the computer (while the STM32CubeProgrammer is not on)3. Start the application4. Un-Check this option5. Try to connect and once the following error shows exit the programmer application and keep the board connected6. Relaunch the programmer application (with the board connected and the NRST pin held low7. Press connect and disconnect the NRST pin within one second (I do the Zero, One and release movement)8. The board Should connect (It worked for me for every board that I have trie

Hi all,I realized my custom external loader for STM32CubeProgrammer and it works fine when used from the Programmer GUI.I can program, erase ad read external flash.Now I'd like to use the command line interface but I cannot find how to mass erase the external flash from CLI.If I load a .HEX file for the external flash the affected sectors are erased and programmed perfectly, but issuing the -e all command anly erases the internal flash.Since my .hex file contains only used external flash areas, I'd like to do a mass erase before writing so I'm sure that flash is clean before writing.External mass erase is possible from GUI so I suppose it is also possibel from command line...Any suggestion?Thanks,Davide

I am using the latest version of the STM32CubeProgrammer (v2.16.0) and am connected to a STM32F405RGT6 via an ST-LINK/V2.The problem is finding the nBoot0 and nBoot1 settings under the Option bytes tab in the software. Does anyone know where I can find this? I have seen other people having these settings under the User configuration but I dont seem to have does. See image.Thank you.

Is there any option to write option bytes to control the boot option for STM32G070 from uart after the first upload or any solution to change the option bytes from stm32cubeprogrammer?I can't change the boot config from option bytes using the stm32cubeprogrammer, I've used multiple virgin mcu, STM32G031, STM32L071, STM32G070, but none of it can change the option bytes.Possibly the closest problem is like in troubleshooting section of https://www.beningo.com/configuring-the-stm32-option-bytes-using-segger-j-flash/

When I open the Cube Programmer (2.14) I'm greeted by a Connection error message:The server connection is not established.The network connection is required to download updates.Please check your proxy settings. I'm not behind a proxy and tried various proxy settings, reinstalled Cube Programmer and older versions, disabled my firewall and yet can't connect to the server. This seems to prevent me from flashing my STM32G431CB as the Cube programmer needs to download something for that. When I try to program a STM32F446ZE everything is fine. The error message while flashing is:stm32 Error: failed to download Segment[0]Error: failed to download the File Thank you!

Hi,The font size is way too small for me. I use Ubuntu20.04, system-wide font scaling factor set to 1.5. This does not affect the font in STM32CubeProgrammer. It is really small.Any ideas how the font size can be increased?STM32CubeProgrammer - v2.16.0Thank you!
