STM32CubeProgrammer (MCUs)

I want to use the STM32CubeProgrammer C++ API to do high-speed real-time automated debugging (i.e. use it as an oscilloscope). I used as a basis the Example_2 given in the API's documentation. The STLink is detected since I can get info from it which I confirmed with the CubeProgrammer. However, when I try to connect to it the connectStLink function returns the value -545 (see the screenshot). I have tried to change various parameters for the past two days with no effect, I am at a complete loss. Here is my very simple code:Thank you for your help. #include <DisplayManager.h> #include <stdio.h> #include <iostream> #include <CubeProgrammer_API.h>   void initProgBar() { std::cout << "initProgBar"; }   void MylogMessage(int msgType, const wchar_t* str) {}   void loadBar(int x, int n) {}   int main() {   debugConnectParameters *stLinkList; debugConnectParameters debugParameters; generalInf* genInfo;   displayCallBacks dc; dc

I'm working on a project that requires programming a large quantity of STM32 chips with the same code base. The chip is STM32L476RETx. While researching, I came across options like the STLINK-V3MODS and ST-LINK/V2, but they seem to support programming only one controller at a time.Could anyone suggest alternative methods or tools that would allow me to program multiple STM32 chips simultaneously? I'm looking for efficient ways to streamline the programming process for a large batch of chips. Any insights or recommendations would be greatly appreciated. Thank you!

hi in the previous tool DFude v3.0.6 we had a button called -leave dfu mode,that button made disconnection and reset to MCU if you were connected with USB, so after flashing the MCU jump to application FW,now in the cube programmer, we don't have this option, just disconnect, and then you need to manually reset the MCU,overall we try also to do that from the USB_EXAMPLE from the API folder in the cube programmer file,but can't do reset from the usb , is there any way?  

Hi all, new to this. I am trying to remove read and write protection. In the option bytes, I cannot change wrp-0 and wrp-1. The progress bar on the lower part of the gui says 100% but does not actually finish. when I check the live update box, I get a read failed message. Thanks in advance.

Hi,I wanted to put some global variables in RAM2 sector in my project based on STM32L4A6VGT6.To do it, I edited file STM32L4A6VGTX_FLASH.ld and I added "__attribute__((section(".ram2")))" to my variables. It compile and works - I can update microcontroller via programmer and I see variables in RAM2. However, I can't download this file to microcontroller with the same ELF file using USB - I turn on STM32 in boot mode and while download file via USB, I get an error "Error: failed to download Segemnt[1]". When I take back changes in STM32L4A6VGTX_FLASH.ld, I can again download ELF via USB. I download file using STM32CubeProgrammer. Is it just imposible, to download ELF with modifed flash file? Or maybe should I edit it some other way?In line 177 you can see my RAM2 init.  /* ****************************************************************************** ** ** @file : LinkerScript.ld ** ** @author : Auto-generated by STM32CubeIDE ** ** @brief : Linker script fo

I've written a fairly simple test case for using the system bootloader to boot from flash bank 2 on a STM32F429ZIT6U (developing on a Nucleo F429ZI board). With stdio redirected to a UART, I'm able to direct the code to:Mass-Erase Bank 2Copy the entirety of Bank 1 to Bank 2Set the BFB2 bit The function that sets BFB2 looks like this:void boot_bank_select(uint8_t bank_bit) { FLASH_AdvOBProgramInitTypeDef optionbits = { .OptionType = OPTIONBYTE_BOOTCONFIG, .BootConfig = (bank_bit) ? OB_DUAL_BOOT_ENABLE : OB_DUAL_BOOT_DISABLE }; HAL_FLASH_OB_Unlock(); HAL_FLASHEx_AdvOBProgram(&optionbits); printf("Waiting for option bit write...\r\n"); HAL_StatusTypeDef rc = HAL_FLASH_OB_Launch(); if(rc == HAL_OK) printf("Bank select completed.\r\n"); else printf("Bank select failed.\r\n"); }By placing a few strategic breakpoints, I can see that once the option bit write takes place, printf starts causing an endless reboot cycle. Code in main() executes up to the first place printf() is ca

Hi all,we have developed an external loader to write a SPI flash. Start address is 0x9000000The loader was written following the ST procedure and disabling all interrupts.All works good but for file of dimension greater than 500k the download fail.For example for a file of more or less 196k we saw from our custom UART terminal that Cube programmer split the file into two pieces of roughly 90k. At the end of the first chunk we correcly see that Cube programmer change write address to 0x90016300Bytes written: 90368Bytes written: 90624WRITE RECEIVED ADDRESS 90016300BYTES TO WRITE 91028Bytes written: 90880Bytes written: 91136When the download fail (with a file of 900k) the programmer split the file in pieces of roughly 300kFrom consolle output --> BYTES TO WRITE 339968We see that file download is going on up to 112896 then the Programmed perform a reset and start to write again from the first location!!!Bytes written: 112640Bytes written: 112896INIT --> Reset occurs!!!WRITE RECEIVED

As per title. I can build the SW but when I try to flash with CubeProgrammer my Nucleo f446re I get the error that no probe is detected. I am pretty sure that I am missing ST-LINK drivers. I made a search on the community forum and all I could have is this 2010 post ending that some development is underway. As it is 2024, what is the outcome? How can I install st-link drivers for my Linux distribution?

We are using the safety lib (-sl) command with X-CUBE-STL library. Without <pattern> parameter, it is working. When trying to use 0xFF for <pattern> parameter, generated .elf is not even valid and cannot be loaded. Is there a workaround for this?For context, as we were discussing in this thread, when there is an empty word between .isr_vector and .text sections, the empty space seems to be filled with 0x00000000 in the elf, in the device it is an empty word of 0xffffffff, and the CRC check in the firmware fails. Changing alignment to 8 fixes this. We were wondering if <pattern> parameter would solve the issue too, but we couldn't try it as the resulting elf is not valid.

Hello,I use Atollic True STUDIO as a development environment and usually use it to program the STM32L4.As a test, I uploaded the generated project.hex file to an STM32L4 using the STM32CubeProgrammer. After reading the flash with the STM32CubeProgrammer, I noticed that the same code is not in the flash as by programming with the Atollic True STUDIO.For example: Is that normal?What is extra added by Atollic True STUDIO? Thank you in advanceMartin 

Is it enough to drag-drop the app from Application folder to thrash bin or is there anything else I should do?

Hey Team, I am working on STM32H745 for display project.I have faced following issue. Some time when I was program my device it was completed in 1.38 minutes usually it takes around 4 minutes because of external flash erase and program loading. 1) Issue was on device that took ~1.31 minutes to program it went to hard fault.2) On device that took ~3.51 minutes to program no issues were found.Controller:  STM32H745.External Memory using QSPI: W25Q512JV.configuration of memory /*W25Q512JV memory parameters*/#define MEMORY_FLASH_SIZE 0x4000000 /* 64Mbit =>8Mbyte */#define MEMORY_BLOCK_SIZE 0x10000 /* 64KBytes */#define MEMORY_SECTOR_SIZE 0x10000 /* 4kBytes *///0x1000#define MEMORY_PAGE_SIZE 0x100 /* 256 bytes */#define TOTAL_PAGES 262144 /* Total number of pages */   

How do I solve this error? "Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication"I use SWD. I made the cable for SWD communication. The cable is connecting ST-LINK V2 between board. Yesterday, well, was connected to STM32CubeProgrammer.But today it wasn't connected suddenly.....I did everything I could by exploring the STM32 community.Changed ST-LINK V2, the cable, reset mode, etc......I saw massage what "ST-LINK error (DEV_TARGET_CMD_ERR)" in hardware rest mode.But I don't solve this error.Please help me....

Hi, i was wondering if it is possible to make an exact copy of an existing STM32F405RGT6 and write to another. The use case for this is an open source motor controller (VESC). i have a fully functional board, and one that i have replaced the stm32 on due to it having an internal short. (Im not exactly sure what happened, the LDO was getting very hot and there was 5v on both Vin and Vout, removed LDO and Vin and Vout were shorted, removed stm32 and short went away. soldered in new LDO and STM32 and it now powers up). I can relfash it via SWD through VESC tool, which includes the firmware for some of the variations of hardware, using the functional board as the link between my computer and the new board by connecting the CLK,DIO and GND between the 2, but none are the right configuration. The company that sold these has been defunct for years, and i cannot find the firmware anywhere, so i was thinking if this was possible, this would be the easiest route. the alternative being reverse en

Hi, I am new to STM32G4 series. I am implementing dual bank firmware update on STM32G473 custom board. I've prepared two identical bin files(compiled to 0x08000000), and flashed them to 0x08000000 and 0x08040000.With options bytes:BFB2=0nBOOT0=1nBOOT1=1nSWBOOT0=1My board boot from BANK1 and function correctly.Then I tried to change BFB2 to 1 with STM32CubeProgrammer to boot from BANK2. According to AN2606, it will first boot into system bootloader, and the loader will do valid bank check and boot from it.However, our board boot into BANK1 code. But I've confirmed by debugger they've entered system loader before running BANK1 code.I used the following code to check BANK, get_bank() always return 0/** * @brief get current bank * @retval int 0 for bank 1, while 1 for bank 2 */ static inline int get_bank() { return READ_BIT(SYSCFG->MEMRMP, SYSCFG_MEMRMP_FB_MODE); }

Hello,I have a project where one of the requirements is to activate the iwdt in some defined circumstances, and refresh it in other circumstances also defined. I need to collect evidence of the correct implementation of iwdt in such a way that the acceptance criteria of these requirements are validated. (And the code can not be modified during the test to put some while(1) that makes iwdt to be triggered, or add some function pointer to a non valid address. The code must be validated as it will be flashed in the product).I had thought to force a hard fault using the STM32CubeProgrammer. Is it possible? Is it possible for example to make the program jump to a not allowed address (e.g. set the PC register to 0x0000000000) to force a hard fault on request to test the iwdt? The idea is to automate the tests, so being able to do it using the cli commands of the STM32CubeProgrammer would be a great help.Thank you very much in advance.

Hello,I am using the CubeProgrammerAPI.dll in a C# software and I get this error :CubeprogrammerErrorNoFile = -4, when I use the download function.I don't understand why this file path issue persists. Even after changing the directory, the problem persists without success.Here is my function:string filePath = @"D:\DFU\CodeChanges_18_GasTypeTempComp.hex"; var filePathAdapted = string.IsNullOrEmpty(filePath) ? "" : filePath.Replace(@"\", "/"); uint address = 0x08000000; uint isverify = 1; uint isSkipErase = 0; var password = ""; var download = CubeProgrammerApi.downloadFile(filePathAdapted, address, isSkipErase, isverify, password); if (download != 0) { Console.WriteLine($"Download Error {download}", "No USB DFU available\n"); CubeProgrammerApi.disconnect(); return; }

Hello,I am using the CubeProgrammerAPI.dll in a C# software and I get this error : CUBEPROGRAMMER_ERROR_WRITE_MEM when I use the download function.

Hi,I'm working on download an ".elf" file on MCU without using the CUBE Programmer Application.I need to start the "STM32_Programmer_CLI.exe" from any folder path, other then the default:C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\binI don't want to move on the work directory the entire "...\STM32Cube\STM32CubeProgrammer"  that is 750 MB (in this way it works).I already tried with the only "bin" folder, but it does not work.Anybody know what files and folders are strictly necessary to do this?Thank you. 

STM32CubeProgrammer v2.15I'm having the same issue identified in the following post in the latest (as of now) version of STM32CubeProgrammer: https://community.st.com/t5/stm32cubeprogrammer-mcus/flashing-elf-with-stm32cubeprogrammer-flashes-garbage-before/td-p/154225Can that discussion be re-opened or an update provided here?

I'm using a custom board for the STM32F070 device. I can't seem to connect to the USB DFU due to the device being in read protect level 1. I've verified that it is not in level 1, but actually level 0, using the ST-Link Utility and Cube Programmer via an ST-link. When I use the CLI, I get a message saying that the read protection is set and I should unlock it. When I do, the device still acts as though it is in read protection level 1. When I try to unlock it using the CubeProgrammer, I either get an error saying the device is read protected or that I need to power cycle the device, but still won't connect.  I have also confirmed that the USB connection is fine by simply printing "HelloWorld!" to a putty console. Any ideas as to why the device seems to automatically re-lock, or just not want to talk when in the USB DFU?

Hi,I'm working on the STM32L476-Discovery board, Win10 host.I created a simple application, which works.Now I changed the start of the address to 0x08001000:MEMORY { FLASH (rx) : ORIGIN = 0x08001000, LENGTH = 1024K RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 96K }I erase the board (validating 0x08000000 is 0xFF, 0xFF...).Now I flash my ELF:STM32_Programmer_CLI.exe -c port=SWD -d .\build\TestAppMin.elfLooking at address 0x08001000 - the application data is correct.But, looking at address 0x08000000 I don't have 0xFF anymore... I have the beginning of the ELF file - see image: 

Is it possible to use the DTR/RTS pins of a UART bridge (such as FT232RL) to automate entering the bootloader in system memory for flashing firmware using STM32CubeProgrammer? Has anybody achieved this?

Hello,I'm curious if I am going through the correct procedure to put th H753I eval board in DFU mode. I have the power jumper JP10 on PSU. I then put a jumper on JP3 which is labeled BL_BOOT0 (which as far as I know puts the H7 in DFU mode when pulled high). I then plug in the PSU and then plug in usb cable to my pc and to the eval board. I've tried all three OTG ports, but I get no activity on my pc. When I check device manager, nothing new shows up at all. I've seen other see STM32 BOOTLOADER and STM32 in DFU mode, but I don't see either of these.Any help or insight would be appreciated. Thank you.
