STM32CubeProgrammer (MCUs)

Hi! I'm trying to program a Creality 3D printer 4.2.5 board with an STLINK. This board has a STM32F103RE MCU. I've already successfully flashed this board more than once before with STM32CubeProgrammer. I recall at first it wasn't allowing me to connect either, but then I used the reset jumper on the board to reset the MCU and removed the jumper wire right after hitting Connect and it allowed me to connect. But after programming an open source bootloader and then the main 3D printer firmware right afterwards I'm now unable to connect again. The issue is that I did this (with the Reset jumper wire) whilst the board was on my desk, and not mounted inside the fully enclosed printer. It's not possible for me to be fast enough to hit Connect and turn myself to the printer behind me to remove the jumper wire. So I was wondering if it was possible to connect the Reset pin from the STLINK to the correct jumper pin attached to the Reset pin on the MCU to automatica

Hi All,I have two questions:1. Does the STM32U5 microcontroller support reversible RDP Level 2?2. I have attached the steps we followed - it appears that RDP Level 2 is being unlocked, but afterward we are encountering a DEV_TARGET_NOT_HALTED.Could someone please review the steps and helps us resolve the issue?    

Hello, Stm32cubeprogrammer installation does not proceed to the final stage, it remains at step 8 and is not completed. I tried the program on three different PCs with administrator rights, the result is the same, the installation does not complete.

Hello forum,i'm working with a custom design where a STM32H743XIH6 is provided on the board along with an USB connection. I'm actually dealing with an issue on USB firmware programming using STM32CubeProgrammer v2.19.0 (up-to-date, but same issue occur with previous versions).When downloading firmware the following error occurs:10:34:53 : STM32CubeProgrammer API v2.19.0 | Windows-64Bits 10:34:59 : UR connection mode is defined with the HWrst reset mode10:34:59 : USB speed : Full Speed (12MBit/s)10:34:59 : Manuf.

Hi, after doing a full chip erase over a device with a STM32F103, it's impossible to download a new version over DFU with the STM32CubeProgrammer. After I press connect it shows up corrupted data on the Manuf. ID, Product ID and Serial Number parametres, and when I tried to download the firmware it threw an error.The program crash if I press to many times the USB refresh button and If I press programming a few times. We change a few things related to memory on the device and I guess we messed up with something but I don't know how to recover the MCU after this. RegardsRafa

I have two stm32f429 Discovery boards. I programmed one of the board using cube ide; the output of which was as expected. Then using cube programmer I read and saved the bin file from that board. Using that bin file I programmed my another board which was successful, but there was no output.Is there any another method to do this?I am doing this because I want to save bin file from my custom board and program it to another board and I don't have original code.

I'm trying to configure BOR using STM32CubeProgrammer but I can't locate it on Option Byte. Even if I refer to RM0091 manual there's no section about BOR levels. 

Dear STMicroelectronics Support Team,I am experiencing a persistent and frustrating issue with STM32CubeProgrammer on my Windows 10 system, where the top menu bar (File, Edit, Options, Help, etc.) is completely missing when the application launches. The main window appears, but without the menu.This issue persists across different versions of STM32CubeProgrammer.Here are the detailed symptoms and troubleshooting steps I have already performed:1. Problem Description:When launching STM32CubeProgrammer (both v2.19.0 and v2.18.0), the main application window appears, but the entire top menu bar (File, Edit, Options, Help, etc.) is absent.The application does not crash immediately; it simply displays without the menu, making it unusable. (Initially, it would flash and disappear, but after a clean reinstall, it now stays open without the menu.)2. Key Observation (Important Clue):STM32 Trusted Package Creator, another STMicroelectronics GUI tool, works perfectly fine on the same system, inclu

I am contacting you to report and request assistance with a recurring issue I am facing while working with the STM32G071CBT6TR microcontroller. I am experiencing problems with the bootloader during UART-based firmware uploads.The microcontroller programs successfully only the first time via UART using a USB-to-Serial converter (FT232RL). However, after a successful first upload, subsequent upload attempts fail, even though nothing changes in the hardware or the code.Technical Setup:MCU: STM32G071CBT6TRProgramming Method: UART (USART1) using USB-to-Serial (FT232RL)Baud Rate: 115200Parity: Even (as required by STM32 bootloader)Boot Mode Configuration:BOOT0 is connected to 3.3VReset pin is manually triggered before uploadSoftware: STM32CubeProgrammerPort Status: COM port opens successfullythe observed behavior: First Upload:Upload works perfectly with the default settings using STM32CubeProgrammer over UART.Following Uploads:All subsequent attempts fail with the following error:CopyE

Hello,I have been trying to flash firmware from one MCU to another MCU, and everything until actually jumping to the memory address where the firmware has been flashed to is working so far.Here's what I do in my code:I have the "Application" project, which is basically the firmware to be flashed. I build this project in STM32CUBEIDE, and then I take the application.bin file and convert it to a C array using some software. Then, MCU-1 uses that C array and flashes it to MCU2. MCU2 has 3 applications slots in its flash memory, and it flashes the bytes it receives to application slot 2 (0x08080000). Once it finishes, it jumps to the starting address of the second application slot using the following function:void BOOT_JumpToAddress(uint32_t address) { printf("Jumping to 0x%08X\r\n", address); // Function pointer to reset handler void (*app_reset_handler)(void) = (void *)(*((volatile uint32_t *)(address + 4U))); // Disable RCC, HAL, reset SYSTICK, and remap vector table offset HAL_R

Hello everyone,I am currently writing a GUI application with QT. The STM32CubeProgrammer API is integrated in the project. So far I was able to flash FW, use functions like massErase and execute without any problems  (All these over UART). Now my MCU needs the nBOOT0 option bytes to boot correctly.I have tried several times with the STMCubeProgrammer API function "sendOptionBytesCmd" but it does not work. I always get a "-6" as return value. Does anyone have an idea how to solve this ?This is what my code looks like.qDebug() << "Setting Option Byte nBOOT0 to 1"; int sendOptionBytesCmdFlag = sendOptionBytesCmd((char*)"-ob nBOOT0=1"); if (sendOptionBytesCmdFlag ! = 0) { disconnect(); qDebug() << "Could not set Option Byte nBOOT0 to 1"; } qDebug() << "Option Byte nBOOT0 set to 1 successfully! " << sendOptionBytesCmdFlag;Thanks in advance :)

Hi,I am currently using the following microcontroller (STM32F100C8T6B) in my design. I have built my project using the STM32CubeIDE (STM32CubeIDE Version: 1.18.1). I have created the following output files (BIN, HEX, and ELF) and I was able to RUN and download the source code onto my board (Design) using the STM32CubeIDE using the "elf"  file successfully. I used the Segger J-Link as a probe.If I used a different Flash Programmer such as STM32Cube Programmer or ST-Link instead of STM32CubeIDE to download the my code onto the board using the output files I created such as (.BIN, .HEX, .ELF or .SREC), it download onto the the board, the board doesn't not programmed or the download doesn't work.It appears that the board is programmed only whenever I use the STM32CubeIDE environment, not the regular Flash Programmers. The bottom line is that it works with IDE environment, but not with the regular Flash programmers are used. I am not sure what the problem is an

I have designed a board using the STM32U083KCU, i have programmed it once with a simple program made with STM32CubeIde that only prints "Hello\n" over USART2 on pins PA2 and PA3. I have flashed the chip over the same pins by holding the BOOT0 Pin high and power cycling it. It flashed it when it was blank. Now i tried to flash the full Program i wanted to upload and tried to upload it over the same method, using STM32CubeProg over UART2 on pins PA2 and PA3. I have held BOOT0 high. But it didn't flash, it said the Device is KO. I tried lowering the baud rates but this didn't help. I have tried to program it using SWD with a STM32Nucleo as the programmer. But the SWD doesn't connect to the chip. The STM works as it sends the "Hello\n" message to the computer if BOOT0 is low but for some reason also when BOOT0 is High. Is there a possibility to rescue the MCU ? Thank you for your time (:

Hello everyone,We're currently working on an external memory loader project using Keil, targeting both the Keil FLM Downloader and STM32CubeProgrammer. (We convert the .axf output to .FLM or .STLDR accordingly.)The flasher is designed to program an application into the external NOR Flash on the NUCLEO-H7S3L8 board using the XSPI interface.Our work is based on the following reference project:H7S3L8 - Template_XIP When we used the loader with the Keil FLM Downloader, everything works perfectly. The loader operates without issues.However, when we switch to STM32CubeProgrammer, we encountered with RW is not being initialized properly.We’ve ensured that the relevant RW data region in the scatter file have load and execution addresses set to AXI SRAM (0x24000000).Despite this, it appears that CubeProgrammer copies the data from AXI SRAM to ITCM (0x00000000).We believe, CubeProgrammer might be running a some kind of startup code and during that process, the initial values of RW variables

Well, that's the strangest 'support' department I've ever dealt with.In trying to download the STM32CubeProgragger for Linux, I've found that the download halts at ~40Mb of some 280MB, or so. Tried downloading as user, and as guest, no luck. Tried different browser, and different computer, no luck. All 3 versions of the aforesaid program have similarly dysfunctional links.Quick word to ST 'support', and it seems my profile doesn't justify lifting a finger, and I'm told that, before being referred to community support. After two weeks in ST 'support' dystopia, I still don't have a copy of the tool.Here's the thing...I'm a customer. I can't buy thousands of ST microcontrollers, but I did buy some. That makes me an ST customer, and morally due a means to program my investment. How can I be expected to grow to a larger customer, if I cannot, even by begging a very rude and helpless 'support'?Okay, the download problem is not within my spere of influence. Maybe it is, or isn't within ST's,

Hello ,I recently purchased the STM32N6570-DK Discovery Kit. When I first powered it on, it showed a default video demo on the LCD along with live imaging, which I assume is the factory firmware.Now, I would like to try some basic operations like UART communication and toggling an LED, so I created a new project for that.Before flashing my custom code, I used STM32CubeProgrammer to read and save the default firmware as a .hex file from the board.Before running my custom application, I wanted to restore the default original  demo by reloading the saved .hex  file. However, when I tried to program the board with this .hex file using STM32CubeProgrammer, it failed to load and showed an error (attached in the image).So here are my questions:Is it possible to directly reload the saved .hex  file to get back the default factory demo?Or do I need to generate a Project_trust .bin file with a proper secure header and flash that instead?What is the correct method to restore the fa

Hello all,I have a custom board with an STM32U5A9 mcu with an external MT25QL128 flash for TouchGFX assets.I have a working loader for IAR Embedded workbench and I'm trying to port it to work with the STM32CubeProgrammer.When building as a normal project - that is a minimal cubemx project with just ospi and clocks enabled and with my ospi functions it runs fine, read/write/erase the flash without any issues.However, when I move it to the loader framework the init function crashes - I believe in a hard fault or some kind. It's difficult to tell for certain since debugging the loader is tricky.The cube programmer only tells me "Error: Data read failure".I realized that if I return early from the Init, no error is issued and the flash only read zeros - which makes sense because the ospi is not initialized yet.Thus I found out that the issue so far is on HAL_OSPI_MspInit function that was generated by cubemx.This part of the code returns 0: __HAL_RCC_OSPIM_CLK_ENABLE(); return 0; __HAL_RC

Almost all development boards produced by Chinese vendors use CH340 as the uart converter chip, I would like stm32cubeprogrammer to be able to control the RTS and DTR of this chip.If the feature works fine for the FT232RL, I don't know why it won't work for the CH340.https://community.st.com/t5/stm32cubeprogrammer-mcus/boot0-nrst-control-with-dtr-rts/td-p/255331 

Dear All, Hi, I am using STM32CubeProgrammer in Ubuntu system, but the resolution is not right. Could you please help me fix the problem? Thank you so much!Best

Hi,I have got a HDMI monitor and I am hardly able to see what is displayed. This issue has been around for years. Apparently, the issue is because of an old java version. My question is if that is ever going to be fixed and when? No next version please.Thanks,Hans

Hey, I'm just trying to use the BLE STM32UB5x in the board B-U585I-IOT02A. I used the following configurations for the STM32CubeProgrammer like suggested here (https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_BLE_Hardware_Setup)SW4 OFF, SW5 ON, SW3 SYS, SW6 0stm32w5x_FUS_fw.bin @ 0x080EC000stm32w5x_BLE_Stack_full_fw.bin @0x080C7000ble_at_server.hex Then, I switch SW4 ON, SW5 OFF and added this to main.c/* USER CODE BEGIN 0 */ static HAL_StatusTypeDef BLE_SendCmd(const char *cmd) { HAL_StatusTypeDef ret; const char crlf[] = "\r\n"; char response[64] = {0}; printf("Sending BLE command: %s\r\n", cmd); ret = HAL_UART_Transmit(&huart4, (uint8_t *)cmd, strlen(cmd), 100); ret |= HAL_UART_Transmit(&huart4, (uint8_t *)crlf, sizeof(crlf)-1, 100); if (ret != HAL_OK) { printf("UART transmit failed (err: %d)\r\n", ret); return ret; } HAL_Delay(50); ret = HAL_UART_Receive(&huart4, (uint8_t *)response, sizeof(response)-1, 100); if (ret == HAL_OK) { printf("B

I want to use stm32H5 series microcontroller and I am trying to write from STlink... I can access the microcontroller by SWD (I can check Option Byte), but I can't write. I can write to the USART via the bootloader with TrustZone disabled, but... I would appreciate it if you could provide me with some information about this.

Hi all,I am working on the development of an external loader for STM32CubeProgrammer.CPU is STM32H743, flash memory is W25Q512 in quadspi mode.I have a problem in indirect mode: it's working (read and write), but in read I have long timeouts: //Send command if (HAL_QSPI_Command(&FLASH_QSPI_PORT, &sCommand, QFLASH_DEF_TIMEOUT) != HAL_OK) { return HAL_ERROR; } // Receive data if (HAL_QSPI_Receive(&FLASH_QSPI_PORT, buffer, QFLASH_DEF_TIMEOUT) != HAL_OK) { return HAL_ERROR; }  It seems that HAL_QSPI_Receive goes ok on the first chunk of data, then when cubeprogrammer calls a Read for the following chunks I always have a timeout in HAL_QSPI_Receive, as if this call never finds the FTF or TCF flags active (QUADSPI_SR): HAL_StatusTypeDef HAL_QSPI_Receive: ..... while(hqspi->RxXferCount > 0U) { /* Wait until FT or TC flag is set to read received data */ status = QSPI_WaitFlagStateUntilTimeout(hqspi, (QSPI_FLAG_FT | QSPI_FLAG_TC), SET, tickstar
