STM32CubeProgrammer (MCUs)

Hello,I'm trying to develop a custom external loader for STM32WL5 device, in a custom board using SPI flash memory Winbond W25Q80DV.In the past I've already developed external loaders successfully for other MCUs and boards.I again followed the steps described by official documentation, hints on this forum, examples in folder bin/ExternalLoader of CubeProgrammer: I set up a new project with CubeIDE, compiled, created .stldr file and copied it in ExternalLoader folder. If I debug the project everything is ok. Besides, opening CubeProgrammer, I correctly see my new external loader in external loader list and information provided are correct.The problem is that when I try to read from the SPI flash mapped address (set to 0x9000 0000 in this case) using CubeProgrammer, the procedure fails. Selecting Verbosity level 3, I can see these messages: 11:11:37:994 : UR connection mode is defined with the HWrst reset mode11:11:38:061 : ST-LINK SN : 54FF6906668549541930168711:11:38:062 : ST-LINK

Hello all developers Today I came to ask for advice. I have an STM32 Nucleo-144 development board with stm32H723ZG. At first it worked fine. But suddenly there was a problem of not being able to connect to the stm32cube programmer. I was wondering why the Voltage was about 0 volts.  

I briefly changed the option byte setting through CUBE ProgrammmerIt was changed well before, but I tried to change the DMEP setting and return it because I couldn't want it, but an error occurred and it is not changing The error appears as follows, so please tell me how to fix it18:26:25 : Error: Expected value for Option Byte "DMEP1": 0x0, found: 0x118:26:25 : Error: Expected value for Option Byte "DMEP2": 0x0, found: 0x118:26:25 : Error: Option Byte Programming failed Or modified by application after OB_LAUNCH  

Hello, i use STM32CubeProgrammer for flashing devices with .hex files, but after the update from version v2.11.0 to latest v2.15.0 the downloading doesn't work (it also doesn't work with 2.14.0). The .bin download works fine in both versions.  The MCU that I use is STM32G483.The message from log is:12:02:17:022 : erasing sector 0027 @: 0x0800d800 done12:02:17:022 : sending a page erase request @: 0x0800e00012:02:17:039 : erasing sector 0028 @: 0x0800e000 done12:02:17:039 : erase: 0675ms12:02:17:039 : Erasing Segment <1> Address <0x0801DFE0> Size <2>Bytes12:02:17:039 : Erasing memory corresponding to segment 1:12:02:17:039 : Error: Sector size: 0x00000002 Bytes is out of range12:02:17:070 : Error: failed to erase memoryThe problem is with two last bytes in the hex file (these bytes store the firmware version). If they are at the end of the memory (and a different flash sector than previous bytes) the downloading fails in new version of Programmer. 

when i create this program everything is ok until step7. however i cant pass step 7and window is below.

Hi,I have 20 boards in a 4x5 panel board. all boards have the same MCU. is it possible to program all boards via a panel at the same time? if so, how can I do that? which software and hardware tools do I need?Thank you.

Hello,I recently updated from 2.14 to 2.16 and I'm having a DFU download problem. The board is recognized correctly, but the problem occurs when downloading the firmware file. The sectors do not get cleared because they are found to be nonexistent.I'm using an STM32L433RCT6 chip. I downgraded to 2.14 and everything works like a charm.Attached is the log file.

Hello,  I'm trying to setup a production line where I have to flash a serial number on each piece after it has been programmed with the standard firmware. I put the serial number in an hex file, and I'm trying to write it using STM32_Programmer_CLI but I need to skip the flash erase before programming.  I tried using 'ske':  STM32_Programmer_CLI.exe -c port=SWD -w serial.hex ske but the flash keeps getting erased.  I found out that with ST-LINK_CLI.exe I can use the option 'ske' to disable flash erase, and I tried it, but it seems kind of obsolete because when I launch ST-LINK_CLI.exe -c SWD LPM -P serial.hex ske I keep receiving this error: Note that read out protection is NOT enabled and there is no elf file involved, I'm using .hex files. What am i missing here? From what I can understand SMT32 Cube Programmer should have replaced STLink Utilities, but is it missing fundamental features like skipping the erase of the flash?

stm32cube software is unable to program over 512Kb of binary into STM32F767ZG which is a 1MB part due to wrong identification as 2MB partWe first reported this back in 2021 as https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer/issues/11 and https://community.st.com/s/question/0D53W00001EEBXXSA5/stm32cubeprogrammer-incorrectly-erases-on-dual-bank-1mb-stm32f7best we got so far is "i have also transmitted your issue to our development team with the internal reference 120183"looking for ideas on how to make progress with this issue? we really like cube and our firmware is above 512Kb now

Automatic mode works fine just to download binaries to the MCU.If It try to set option bytes read out protection to BB afterwards, the software will lock.It displays:15:20:13 : UPLOADING OPTION BYTES DATA ...15:20:13 : Bank : 0x0015:20:13 : Address : 0x40023c1415:20:13 : Size : 4 Bytes15:20:13 : PROGRAMMING OPTION BYTES AREA ...And stays on this state forever, If I click "Stop automatic mode" it displays:15:21:55 : aborting on going operation...15:21:55 : Disconnected from device.But it won't work normally. All the features related to non-automatic operation will remain disabled. The only way to bring it back is closing it, and opening it again.When I change the option bytes manually, it works fine.The string I used to set the read out protection is -ob RDP=BBIs there anything else I should do ?Any help will be highly appreciated.

I am getting CUBEPROGRAMMER_ERROR_NOT_SUPPORTED when I try to connect to a device in my code. In their example code is working. Issue is when using with my code. It's an strange issue. I copied all also checked in file comparision. All good but while using other code it's returning CUBEPROGRAMMER_ERROR_NOT_SUPPORTED (-5) error. 

Hello,I have a feature request for the STM32CubeProgrammer.As we know, when we connect the board, we can display the memory fields as like following:But when I disconnected from the board, the fields are gone:I know that this is not a bug, its a feature but, sometimes I want to observe some memory fields when I not connected the board as well. Currently I am copying the memory to somewhere else and reading....I think would be great If you add this feature (Keeping the old data and memory sections on editor) or maybe you can inform the user that these information are not real-time data or, you can add some gray layer top layer on the editor to inform user that data is not available. Bonus request: As we know, the twitter is renamed to X. Maybe you need to consider to change the icon here:

I am testing firmware upgrade API from CubeProgrammer_API. For some reason, it keeps printing that the firmware upgrade failed, but when i check the firmware version of my device, the firmware has been updated. Does anyone know what is the cause of it? The code below is taken from the source codebool retValueFusUp = firmwareUpgrade(L"../test file/stm32wb5x_BLE_LLD_fw.bin", 0x08065000, FIRST_INSTALL_NOT_ACTIVE, START_STACK_NOT_ACTIVE, VERIFY_FILE_DOWLOAD_FILE);    if (retValueFusUp == false)    {        logMessage(Error, "\nFUS Upgrade  failed\n");        return(1);    } 

I am using STM32H563ZI board and trying to develop a UART communication project but I just can't figure how to connect to STM32CubeProgrammer threw UART and always get the error:" Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... "I am having a issues with the UART in general and can't figure out how to transmit data correctly. 

I am working on implementing a firmware update on my electron app using CubeProgrammer_API. I keep encountering issues on connecting to the DFU bootloader in which is giving me CUBEPROGRAMMER_ERROR_NOT_SUPPORTED (-5). I compiled my code into a .exe and run a JavaScript code to execute the .exe. However, when I run the .exe manually, it works fine, but not on my Electron app. I have the latest version of STMCubeProgrammer (2.16.0). 

HiI am trying to get a custom external loader working on a STM32L562VET with a MT25QL128ABA attached over QuadSPI. I have followed this tutorial: https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/external_QSPI_loader.htmland after some modifications, I managed to successfully run the main_test code and everything seems to work fine. I can also see the data in the memory viewer in the STM32CubeIDE.I then continued to build the *.stldr which also seem to work fine. However when I import it in STMCubeProgrammer v2.15.0, I can erase certain sectors or the whole chip. But if I try to download a .bin file (256Bytes random ASCII), I get the following error messages:15:39:48 : Error: failed to download Segment[0]15:39:48 : Error: failed to download the FileIf I go back to the memory viewer, I can see that the data was successfully written to the flash despite the error message. What could be the problem here?I already tried with STMCubeProgrammer v2.6.0 but get

I have a very simple program, but with my board, the debugger does not work properly. It does work on a Nucleo board though. Attached i have the signals, that i could measure on swd clk and swd dio ( brown clock / yellow dio). The are not aligned, but they have the same scale.Programming the target does work. Also now with 8000kHz and NRST connected, unlike in my other thread i had today. See the error here: https://youtu.be/4i2mYk8yuQM I found out, that the counter "DWT->CYCCNT" runs if you hit resume, but the programcode is not beeing resumed.I have now removed the loops, so that there is only a bunch of GPIOB->BSRR |= (uint32_t) GPIO_PIN_10;andGPIOB->BRR |= (uint32_t) GPIO_PIN_10;Also i just letting it run without debugging.It runs for about 771us, independend of how many instructions i put there, so there is a precise time issue. But the curves of the signal dont look as they should. See attached.I just tried it with a fresh generated code from cube mx. Now it ru

Hello, I have made a custom external flash loader(.stldr) file for my STM32 based board. Reading the content of the external flash via CubeProgrammer works fine. But when programming i run into the following problem: CubeProgrammer tries to write partial pages, which fails.device setup in Dev_Inf.c:struct StorageInfo const StorageInfo = {#endif"W25Q_BurnerHMI_PT1_loader_v1", // Device NameNOR_FLASH, // Device Type0x70000000, // Device Start AddressPAGE_COUNT*MEM_PAGE_SIZE_BYTES, // Device Size in Bytes (8192 pages * 512 bytes)MEM_PAGE_SIZE_BYTES, // Programming Page Size (512 bytes)0xFF, // Initial Content of Erased Memory// Specify Size and Address of Sectors (view example below){{SECTOR_COUNT, MEM_SECTOR_SIZE_BYTES}, // Sector Num (512), Sector Size (8192 bytes){0x00000000, 0x00000000}},}; The image i'm writing has a size of 2097152 bytes (2MiB) and in the UART debug print i can see that CubeProgrammer is splitting the image like this:Write(Address:0x70000000, Size:0x7D500, buff

Hello I am using stm32f030f4 and i want to use the STM32Cubeprogrammer in automatic mode , i had tried to use –ob rdp=1 to change the read out protection level to 1 ,but its not working .what is the right option bytes command?

i've installed versions of STM32CubeProgrammer on my windows 10 PC as well as my MAC....i'm following the instructions in um2269 (section 8) on updating firmware, but see a message saying "No DFU detected" under the USB configuration panel....  selecting Connect fails at that point....on windows, the device manager seems to identify a 'Power Shield (Virtual ComPort in FS Mode)' as well as a new 'USB Serial Device' when i plug in my board....  but there is a warning sign that ultmately tells me that windows can't find a driver....  drivers were definitely installed along with CubeProgrammer; and i've run some .bat file under the Drivers folder....do i need to do anything with my (brand new) board???  if i move the sliding jumper to the 'Syst' position *BEFORE* plugging in the board, it doesn't even power up.... 

Hello!I am using STM32 Cube Programmer API to flash a device with ST-LINK. I am using ST-LINK example 1. When I use connectStLink(debugParameters) it returns the value '-545'. Doxygen comments say that if it returns 0 the connection was successful, otherwise an error occurred. I can't find any more documentation about it. Surely the value '-545' indicates to some specific error. After using the getStLinkList() function, the debugConnectParameters look okay, so it means it gets a connection with the device.I can flash (debug) the device through VS Code (using the official STM32 VS Code Extension) and through the STM32CubeProgrammer app with no problems. During one runtime, after a couple of unsuccessful tries it actually flashed the device for a few times and then stopped working again (returnind -545). I haven't made any changes to the code or the connections.I am using mikroProg for STM32 with the ST-LINK V2 adapter. I tried different USB ports with no luck.There isn't much informatio
