STM32CubeProgrammer (MCUs)

STM32 cube programmer doesn't recognize my custom board neither via USB DFU nor USART.My circuit is simply the STM32F070F6, a 12 MHz crystal and some LEDs to control (also caps and res as necessary).Even with boot0 direct in high or low, I'm not able to make the SW identify the MCU.

Hi,I can't get the external loader to work in STM32G491.For the test, I replaced the bodies of the Init()/Erase()/Write() function with LED blinking. I did this to check if the functions are called correctly. For debugging, I used STM32_Programmer_CLI to check the writing of single bytes.If I try to write the STM32F429 I get this log.19:50:54:384 ------------------------------------------------------------------- 19:50:54:384 STM32CubeProgrammer v2.9.0 19:50:54:384 ------------------------------------------------------------------- 19:50:54:384 19:50:54:388 Log output file: !log.txt 19:50:54:390 Command line: -log !log.txt 19:50:54:390 19:50:54:395 Operation [2]: -vb 3 19:50:54:406 Operation [3]: -c port=swd freq=500 reset=HWrst 19:50:54:447 ST-LINK SN : 55FF67065065565040110987 19:50:54:450 ST-LINK FW : V2J45S0 19:50:54:453 Board : -- 19:50:54:455 Voltage : 2.92V 19:50:54:481 SWD freq : 480 KHz 19:50:54:484 Connect mode: Under Reset 19:50:54:486 Reset mode : Hardware reset

Hi,  I'm just starting to play with a NUCLEO-H563ZI and I have some problems with DA discover using my dev boards.I started to do the following steps: Step 1: Create the provisioning file (.obk file)--> STM32TrustedPackageCreator_CLI.exe --obk H5\Config\DA_ConfigWithPassword.xmlStep 2: Program the application binary-->STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -d H5\Binary\MyProject.elf -vStep 3: Move to the PROVISIONING state.--> STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -ob PRODUCT_STATE=0x17Step 4: Provisioning the .obk file--> STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG -sdp H5\Binary\DA_ConfigWithPassword.obkAnd after these steps I just tried the following command:--> STM32_Programmer_CLI.exe -c port=SWD mode=HOTPLUG debugauth=2but here I received the following error: When I saw this I open STM32CubeProgrammer in order to made a DA discover from there but I received also from there an error: In this step from what I saw

It seems the write protection section has disappeared from the CubeMX programmer some time between versions 2.15 and 2.17?  It is not visible in the UI or the CLI.  We are having trouble programming our boards without access to this section.

The  "Introduction to secure firmware install (SFI) for STM32 MCUs" AN4992 does not list the H743 as a supported device.The Secure Programming tab of the latest Cube Programmer V2-18-0 (Jan 20205) states it only supports STM32U0-5 & WBA.Yet the SFI/SFIx tab isn't disabled when connected to an H743VIT6 board.And the STM32 Trusted Package Creator allows the STM32H7 MCU to be selected as a target.Does anyone think that's not going to be confusing to STM clients new this (mine) field?The "STM32 Trusted Package Creator tool software description" User Manual UM2238 runs to 30+ pages of technical description, very far from user friendly.The STM Wiki "How to deploy SSP using a step-by-step approach" only focuses on the STM32MP1 and uses hard coded values specific to that MCU.The only video on YouTube is by Ruchit Naik a security engineer at STM who uses an AI voice.At 3.55 into the video a chart is listed that includes STM32H7 series, but in the list the H743 is excluded!Cle

Hi, I can't erase the external flash or write a new binary on my STM32N6570-DK board. My problem is similar to this post: STM32N6570-DK: Cannot erase external Flash. But the solution in that post didn't work for me.I have tried using two external loaders (MX66UW1G45G, OTP_FUSES) and also with only one loader (MX66UW1G45G). But everytime the erase is failed with this message: `Error: Mass erase operation failed. Please verify flash protection`.I am sharing some screenshots and my OTP export for your reference.Please let me know how to unlock the flash so I can program it.OTP screenshot2 loaders are selected here. But I tried with only one loader too.

Hello ST Community,I am working on a custom bootloader for the STM32G473CCU6 microcontroller to enable firmware updates via the USB DFU interface. I am using the STM32CubeProgrammer API v2.17.0 | Windows-64Bits.The microcontroller has 256 KB of flash memory in dual banks, which is 128 sectors of 2 KB.Flags: BFB2 = 0, DBANK = 1.I need to erase sectors 1...125 and not erase sectors 0, 126, 127.I am trying to do this with the following function:int sectorErase(unsigned int sectors[],unsigned int sectorNbr, char* sFlashMemName = nullptr);But only 64 sectors (0...63) from bank 1 can be erased. Sectors from bank 2 are not erased.I tried using indexes (64...127) and (65280...65343)DisplayCallbacks output when erasing sectors 1, 2:Info: [INFO]: "\nFlash sector erase ... \n"Info: [UNKNOWN]: "DFU status = 0 : OK"Info: [UNKNOWN]: "DFU state = 5 : dfuDNLOAD-IDLE"Info: [UNKNOWN]: "Status: 0, State: 5"Info: [UNKNOWN]: "sending a page erase request @: 0x08000800"Info: [UNKNOWN]: "data: 4100080008"Inf

Hello,I have received the new STM32N6570-DK board a week ago. It successfully runs the "out-of-box" demo FW programmed into the external Flash and I am also able to load and run some simpler examples from SRAM through the integrated ST-Link debugger. However, when I try going further and would like to run more advanced examples requiring external Flash, I am having issues programming and erasing the external flash in the STM32CubeProgrammer. I do follow the steps in the manual (selecting the proper "external loader" MX66UW1G45G_STM32N6570-DK), however I receive the error "Error: Sector erase operation has failed at least for one of the existing specified sectors.Please verify flash memory protection." when trying to erase first 8 sectors or program another binary into the external Flash. Is the external flash locked by some option bytes or OTP? Is there anything that needs to be done to unlock it?I am using STM32Programmer v2.18.0.Attached is the screenshot of the error when it ha

Hi, I am working with STM32L072 microcontroller. I programmed it without any validation or checksum issues, but after reading the firmware and verifying, a mismatch was found in a few flash cells.For downloading firmware I tried STM32CubeProgrammer v2.13.0 and older, also tried STM32 ST-LINK Utility v4.6.0.0 (STLinkUSBDriver.dll v5.1.2.0, ST-LINK_CLI.exe v3.6.0.0 if needed), STM32CubeIDE 1.17.0 and the problem was the same [Error: data mismatch detected at address 0x800FF3C (byte = 0x00 instead of 0xFF)]I try other levels of code optimization, the problem persists, but the corrupted cell positions change.I try to manually change these cells with STM32CubeProgrammer, but after writing to the corrupted cell, the other cells around were also corrupted.This problem exists on all my L072 processors. ST-Link FW : V2J43S7

Can we expect to get lightweight option of the STM32CubeProgrammer for CLI applications (STM32_Programmer_CLI.exe)  that does not require using STM32CubeProgrammer.The whole STM32CubeProgrammer package is over 600MB and contains variety of unnecessary files whereas the good old STM32-ST-Link Utility is only about 35MB and can perform majority of the operation.This is important for custom applications that internally embed ST tools to program ST32 devices. Just because I need to use UR (under reset) mode for my particular target device, I must use STM32CubeProgrammer as the STM32-ST-LINK utility does not support that. And that is quite annoying because my application now must be 600MB larger than it should be.It would be nice to get stripped down version of the STM32CubeProgrammer.

Hi everyone,In automatic mode, does STM32cubeprogrammer do a "Full Flash memory checksum"?It does in STM32 ST-Link utility. Of course, the "Full Flash memory checksum" box is checked.Thank you in advance for your answerIn the log windowSTM32 cube programmerIn automatic mode12:37:22 : Waiting for device n:2...12:37:29 : Memory Programming ...12:37:29 : Opening and parsing file: XXXX12:37:29 : File : XXXX12:37:29 : Size : 21.56 KB 12:37:29 : Address : 0x08000000 12:37:29 : Erasing memory corresponding to segment 0:12:37:29 : Erasing internal memory sectors [0 10]12:37:30 : Download in Progress:12:37:30 : File download complete12:37:30 : Time elapsed during download operation: 00:00:00.83312:37:30 : Verifying ...12:37:30 : Read progress:12:37:30 : Download verified successfully 12:37:30 : Please disconnect device n:2 and connect the next... Manualy12:48:12 : UR connection mode is defined with the HWrst reset mode12:48:12 : ST-LINK SN : XXX12:48:12 : ST-LINK FW : XXX12:48:12 : Board :

Hi STM Devs.I'm currently testing the: STM 32F030F4P6 and STM32 F030K6T6With the STM32CubeProgrammer and ST-Link v2 I could flash the MCUs the first time, but than all other trys run into the following Error Message"Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"This behaviour i had on the two mentioned MCUs.I've tried so far:Switching the Modes and Reset Modes in STM32CubeProgrammer - but no successAny other Ideas?Thanks for your help ps.: UART gives me this errorError: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again..

Hi,I am trying to flash MCU firmware on my STM32L4A6VGTx MCU in bootloader mode over UART using cube programmer v2.17.0. I tried through UI and command line but in both the cases it if failing with error- Operation exceeds memory limits.Please refer output below and screen shot as well as logs attached.=======================================================================C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin>STM32_Programmer_CLI.exe -c port=COM5 br=115200 -e all -w C:\Users\GUR11373\Downloads\LMU-LTE-416-86x-Rev11746.bin 0x08000000      -------------------------------------------------------------------                       STM32CubeProgrammer v2.17.0      ------------------------------------------------------------------- Serial Port COM5 is successfully opened.Port configuration:

Since configuring the STM32WB55CGU6 in STM32Programmer with the following settings, I am no longer able to connect to the chip using ST-Link. I cannot download programs in Keil, and the ST-Link in STM32Programmer cannot connect either. Changing the parameters also does not help with the connection. Furthermore, neither the USB nor UART connection methods are working. However, I can connect to STM32CubeMonitor-RF, but it doesn't seem to be useful. In STM32 ST-LINK Utility, ST-Link is detected, but I still cannot connect. I am also unable to erase the flash because I cannot connect to any software (except STM32CubeMonitor-RF). What should I do to connect to ST-Link?

I have manually verified the FLASH bytes are correct after programming, but the -v option results in "Error: Data mismatch found at address 0x10000000 (byte = 0x21 instead of 0x00)" and the process stops.Isn't 0x10000000 a CCM address and why is it being tested and failing?  See terminal output below: "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=USB1 -d "fw.hex" -v -g 0x08000000-------------------------------------------------------------------STM32CubeProgrammer v2.18.0------------------------------------------------------------------- USB speed : High Speed (480MBit/s)Manuf.

Hi!I would like to ask for a little help. I have a LoraWan E5 wich I want to program with ST-Link V2, but as soon as I want to connect to it in the STM32CubeProgrammer I get the errors below. I also attached the pinout that I follow. I connect SWDIO, SWCLK, 5V and GND to the LoRa e5 mini. If I ping the lora with an AT command it responses on the serial monitor so the LoRa is ok. I updated the firmware wich was successful, also tried to set to reset mode and press the RST button while connecting but none of these are work. How would I be able to connect it?

Hi,similarly to what happened to others with previous versions of STM32CubeProgrammer, an error occurs when I proceed to download the firmware via USB connection:Error: Write failed at address: 0x800…. (address is not always the same)Error: failed to download Segment[0]Error: failed to download the FileThe error in log file is:libusb control transfer error [-9] : LIBUSB_ERROR_PIPEEven the initial connection via USB does not work correctly, as not all information is always read correctly (The initial connection fails if I use version 2.10.0 of STM32CubeProgrammer).Similarly to what others have found, everything works correctly if the connection is made through a USB 3.0 hub. Also, everything works fine if I use DfuSeDemo software, so the problem seems to be related to the STM32 BOOTLOADER driver used by STM32CubeProgrammer.The specs of my system aremicrocontroller STM32F072RBT6firmware version: 0x011adevice id: 0x0448operating system: Windows 10 Pro 64 bit version 22H2USB 3.0Does anyone

Hi!I wanted to ask the following: Is it possible to get the output of STM32_Programmer_CLI.exe as JSON?We use the CLI within one of our internal software tools and the parsing of the output is a little brittle. A structured output format would help a lot. As far as I have seen, the CLI does not support JSON output right now. Is this correct?Thanks,Christian

Hello,First I want to clarify that STM32CubeProgrammer is a very cool and useful software.The purpose of my question is that in my company we need to integrate a "Firmware Flasher" into one of our Software products since we are not going to indicate our customers to download, install, and use STM32CubeProgrammer to update their device's firmware.I was wondering if there is a sample project or code that uses libusb (preferably in C or C++), that I can use as a reference to develop a firmware flasher. I say ideally in C and C++ but if it is not in any of these languages that is ok. I can just translate it from whatever to C++ using ChatGPT.Thanks!

Currently I tried STM32Programmer_CLI and ST-LINK_CLI, both more than 100 times slower than StmStudio - StLink - SWD - MCU. The solution can only work up to 4Hz with 1 mcu and less with >1 mcu. StmStudio can run at least 250Hz with more exchanged data.I tried this: "C:\Program Files (x86)\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" -c port=SWD sn={serialNumber} mode=HOTPLUG speed=Fast -r8 0x20000000 0x8"I need to run up to 20 mcu's simultaneously (6 is minimum), at least one must exchange data faster than 10Hz, prefer >50Hz, the rest can run 1Hz or sub 1Hz. Must be able to be addressed by StLink serialnumber.Mcu firmware is locked so far. Mcu Hardware (circuit/PCB) is locked, so stuck with SWD, no USB/serialport.Would another interface improve interface speed, e.g. Segger J-Link?I am currently trying to get StLink-lib.dll working, will it be faster? Please note, I am a hardware designer so software is not my primary job.ANY advice is a

The command line STM32_Programmer_CLI looks for a database file using a relative path "../Data_Base/STM32_Prog_DB.xml". This causes the "Error: unknown or unsupported device (DevID = 0x0000)" and a segfault.The command line tool should look for this "STM32_Prog_DB.xml" relative to the executables path rather than the current working directory.To demonstrate this issue I have created the following example:Here I am calling the command directly from the $PATH and you see the error(Alans-MacBook-Pro)-(alan)-(~/projects/test) (! 783)-> STM32_Programmer_CLI -c port=swd ------------------------------------------------------------------- STM32CubeProgrammer v2.2.1 -------------------------------------------------------------------   ST-LINK SN : 36FF72064D59303629401543 ST-LINK FW : V2J33S7 Voltage : 3.21V SWD freq : 4000 KHz Connect mode: Normal Reset mode : Software reset Cannot identify the device Error: unknown or unsupported device (DevID = 0x0000) Segmentation fault: 11Now I

Our customer attempted to update the firmware on their device which uses an STM32L433CC. Programming failed to erase and download the firmware on the device. STM32CubeProgrammer 1.4.0 succeeded in programming the device.Customer is using a Windows 11 machine with STM32CubeProgrammer 2.16.0.I have verified that the break occured somewhere between 2.14.0 and 2.16.0 as 2.13.0 works. I have also verified that the behavior is both OS-independent and GUI-independent as I experience the same failure on Linux with 2.16.0 STM32_Programmer_CLI.This is clearly not a hardware issue, but something wrong with the DFU implementation in STM32CubeProgrammer 2.16.0.A log file from the failure on Linux is attached. 

I would like to create a Python GUI application based on PySide6. Within the application, I want to embed the funcionality to flash STM32 devices using STM32_Programmer_CLI.exe command line tool.The STM32_Programmer_CLI.exe comes with an installation of STM32CubeProgrammer. The total size of the STM32CubeProgrammer is 609MB:and I am sure not everything is required if I simply want to use STM32_Programmer_CLI.exeI would like to get some advice on how can I reduce the size of the STM32CubeProgrammer for my particular purpose since it comes with a lot of unnecessary files such as STM32CubeProgrammer.exe itself that I do not need since I use STM32_Programmer_CLI.exe and other files... I only need to have STM32_Programmer_CLI.exe and other must to have dependencies to flash the MCU's via SWD. Perhaps there are other "lightweight" CLI tools or options that I should use for this particular case?I am quite concerned since I may accidentally delete something that is actually required.
