When using stm32cubeprogrammer to burn the program for nucleo-N657X0, the external flash kernel is locked. The inside of the external flash I read is all ffffff. When I erase the code of the external flash, it will report an error that it cannot be erased.

I upgraded STLINK-Utility under Windows 10 from 4.5 to 4.6. It doesn't connect to the DISCOVERY board STM32F407G-DISC1. In the settings it says: "Old ST-LINK firmware/ST-LINK already used". Everything else is greyed out.Can I download version 4.5 still somewhere?

Hello Team,We are currently attempting to perform a silent installation/uninstallation for the application “SetupSTM32CubeProgrammer_win64.exe” on our Windows 11 devices to meet business requirements. Despite trying multiple silent parameters and installation switches, the installer continue to launch in interactive mode but does not proceed silently. This installation is required to support ongoing business operations, and we would appreciate your guidance or confirmation on whether silent installation method is available for this package. Kindly advise us on the recommended approach or provide alternative solutions to help us to achieve this.Thanks

Hi,  I am not able to download the STM32CubeProg. Somehow the download just not start from https://www.st.com/en/development-tools/stm32cubeprog.html?ecmp=tt15529_us_social_may2020#overview Here in the image below you can see that it tries to do something but there doesn't appear any download in my internet browser. Yesterday I was perfectly able to download CubeIDE en CubeMX Is there anyone who can help me?

Hi,I found a bug on new version 2.18 STM32Cube programmer.Of course, I have the same problem with the new version of STM32CubeIde 1.17It looks file STM32_Prog_DB_0x483.xml in \Data_Base folder has changed between versions 2.17 and 2.18If I use the file STM32_Prog_DB_0x483.xml from the version 2.17 and I replace this file in version 2.18, I can access my STM32H730 device.We tried it on 2 different computers.I do not really understand the xml file differences, so I do not know if I can continue to use STM32_Prog_DB_0x483.xml file of version 2.17 with version 2.18 and STM32CubeIDE 1.17Do you have a workaround ?Sébastien

I have started using the cube programmer API integrated in a program I wrote access external eeprom via flash loader.I am able to read/write and download file to it without no major problem after I fought some API things.What I think the cube programmer API misses is a call to mass erase external memory. I see that there is an API massErase but it is documented to erase internal flash. (It takes as parameter a name but it is not documented what it means, The param is called sFlashMemName so I really don't understand it's use)I see there is a way to erase sectors but a single API like massEraseLoader (or massErase(FLASH_LOADER) or something like that would be cool). I know the flash loader can full erase a memory because one of the function it must provide is MassErase. I guess it should be just a metter od exposing such API. What I don't really like about the API design is that the readMemory function does memory allocation! Why such design was chosen? If I am reading memory and p

Hi，There are four STM32 MCU on my board. I want to use one JTAG chain to cascade them. So, Could STM32CubeProgrammer software with J-link or ST-link simulator support JTAG Chain to program several STM32 MCU on the one Chain? Thanks in advance!Best regards!Jason

Hi everyone,I've a strange problem when I write to an external flash memory (S29GL512T) throught a STM32F767 MCU and a custom external loader loaded in the STM32CubeProgrammer.After debugging the external loader several times, I've found that the contents of the buffer that CubeProgrammer gives me for the write operation has partially invalid data. I have done this test in 2 contexts:Using FMC to programm external flash. In this context I have invalid data before programming the external flash. Without using FMC. This context is only for check the content of buffer without FMC interfere and the content matches.So I don't understand why, when you use FMC to program the external flash, the contents of the given buffer are manipulated.This follows shows the original data I want program at address 0x60060000 and the log generated during the programm procedure. # Sector erase 0 Init...<LF> S29GL512T11 found!<LF> Read mode<LF> Sector erase at 0x0<LF> Sector

Hello TeamThis is regarding, facing failure while doing mass erase operation for flash on the NUCLEO-U575ZIQ Evaluation Board. The goal was to do simple project led blinking based on freertos using TFM software base environment.The regression.sh script execution got failed:Due to this issue, unable to flash the software image into the HW with both TFM_UPDATE shell script and STM32Programmer approach.Further while trying to do the mass erase operation for the flash using STM32Programmer, getting below erros:17:53:13 : STM32CubeProgrammer API v2.19.0 | Windows-64Bits17:53:27 : UR connection mode is defined with the HWrst reset mode17:53:27 : Warning: Device changed, refreshing...17:53:27 : UR connection mode is defined with the HWrst reset mode17:53:28 : ST-LINK SN : 004000433233510F3936363417:53:28 : ST-LINK FW : V3J16M717:53:28 : Board : NUCLEO-U575ZI-Q17:53:28 : Voltage : 3.28V17:53:28 : SWD freq : 8000 KHz17:53:28 : Connect mode: Hot Plug17:53:28 : Reset mode : Software res

Hoping someone could help.  I did a full erase on the stm32h747i_disco from the stm32cube programmer.  I attempted (several times) to upload the STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex and got the following error:14:09:58 : Opening and parsing file: STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex14:09:58 : Memory Programming ...14:09:58 : File : STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex14:10:00 : Size : 58.38 MB14:10:00 : Address : 0x0800000014:10:00 : Download in Progress:14:10:04 : Error: failed to download Sector[0]14:10:04 : Error: failed to download the File14:10:05 : Memory [0x08000000 : 0x08200000] - Checksum : 0x139CE03CDoes anyone have a suggestion?

Hey,I'm trying to flash some boards, same as i've done thousands of times with this PC and ST-Link, but Cube Programmer does not load the FlashLoader properly. I'm not using a custom loader or anything, just the default loader for my STM32F051 boards. I'll attach the logs below.I can rule out a defective ST-Link since it happens with other ST-Links as well and the boards are functional as well. A colleague is able to flash them without issues, but using the same ST-Link than him i cannot on my System. I am also able to use the ST-Link normally for flashing and debugging through probe-rs, it just malfunctions in Cube Programmer.It is also not a problem with option bytes as we never set them and all of them are in the default state, i can also confirm this in Cube Prog.I have used STM32CubeProgrammer v 2.19.1 and have since upgraded to 2.20.0 without success. The ST-Link was running Firmware Version V3J16M7B5S1, which i have upgraded to V3j16M8B5S1, again without success. My System

Hi everyone,I try to connect to my NUCLEO board (NUCLEO-L476RG) via STM32CubeProgrammer but I receive the following error message:I reinstalled the STM32CubeProgrammer but nothing changed. I used to write my program to the MCU flash several times using Copy/Paste .bin file directly to the following storage before:but I am not enable to program the MCU via STM32CubeProgrammer. Even I am not able to use Copy/Paste to program the MCU anymore.This is my NUCLEO development board: (NUCLEO-L476RG)Does anyone have any solution please?ThanksPeyman 

So originally, I was using a custom bootloader and painfully sending 32 bytes over custom HID to my device. It works, but it's really slow. Not related, but I just want you to know how dumb I am... Anyway, I followed the tutorial to use DFU USB interface to patch application firmware.https://www.youtube.com/watch?v=n_LDXOQHerU I can't get the DFU programmer working on STM32 Cube Programmer because it can't erase properly. =================== STM32 Cube Programmer Fail ===================19:29:25 : UR connection mode is defined with the HWrst reset mode19:29:27 : USB speed : Full Speed (12MBit/s)19:29:27 : Manuf.

Hi!I have a custom PCB with H7R3Z8T6 & MX25L12833F (16MB Marconix NOR-Flash) hooked up with XSPI1 (Quad SPI). I have been having a very difficult time programming the external memory with the External Loader in CubeIDE.I have followed a forum post (https://community.st.com/t5/stm32-mcus/how-to-create-an-external-flash-loader-for-an-stm32h7rs/ta-p/742005) as a guide to getting started (also https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/external_QSPI_loader.html). The only real difference between the guide and my project is I am powering the memory with 3.3V and therefore did not enable HSLV option byte.My issue is that when I flash the Appli firmware, it fails to verify: (Data mismatch found at address 0x90000002 (byte = 0x00 instead of 0x01). When I read the 0x9... register in CubeProgrammer, it is all zeros until ~0x9003XXXX, after which 0xFFFFFFFF is read (see screenshot below). The extact register where 0xFFFFFF03 is read varies, it chang

I'm unable to run uninstaller.jar in the the uninstaller folder to uninstall STM32CubeProgrammer.

Hello,I’m working with the STSPIN32G4. I was able to program the MCU once successfully, but since then neither STM32CubeIDE nor STM32CubeProgrammer are able to detect it anymore.The main issue is that I did not expose the BOOT0 pin on my board, so I can’t easily force it into system bootloader mode.Has anyone faced a similar issue?Is there any workaround without physical access to the BOOT0 pin?Would SWD still work if the application firmware misconfigured the debug pins?Any suggestions for recovering the MCU in this situation?I’d really appreciate any help or guidance.Thanks in advance! 

Hi,I am trying to install the cube programmer, but keeps failing at step 7 and restarts the installer each time. This is the error I am seeing:com.izforge.izpack.api.exception.IzPackException: An error occurredin java.lang.Thread.run() at Thread.java:750in com.izforge.izpack.installer.unpacker.UnpackerBase.run() at UnpackerBase.java:267in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:339Caused by: com.izforge.izpack.api.exception.InstallerException: File execution failedin com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:319in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:513in com.izforge.izpack.installer.unpacker.UnpackerBase.executeFiles() at UnpackerBase.java:989I am installing as Administrator, if that information helps.Thanks!

Hi everyone,I'm working with an STM32F103C8T6. Even though I haven't programmed any code onto it myself, when I connect with STM32CubeProgrammer, the Registers panel immediately shows “SLEEP” (while on other ST boards it would show “HALTED”). Because of this, I can't perform a Full Chip Erase — the option appears but doesn't work.Here’s what I’ve tried:Connected only SWDIO, SWCLK, GND, and 3.3 V (no NRST).CubeProgrammer shows “SLEEP,” and erase fails.On other boards, “Connect under reset” works fine and allows erasing.Possible issues I suspect:No NRST pin connection → ST-Link can’t halt the MCU before it runs.Option Bytes might have RDP (Read-Out Protection) enabled.BOOT0 pin wrongly tied (stuck in System Memory mode).Some factory test code or previous user code (making MCU go to sleep on reset).What I tried from forum suggestions:Tried “Connect under reset” with NRST — this works on other boards but seems not to work here yet.Any ideas how to force-erase or regain access?I’d appreciat

Hi,I am trying to read peripheral registers on the H523 using STM32_Programmer_CLI.CLI parameters : -c port=SWD -r32 0x42020800 52Result:0x42020800 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020810 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020820 : FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF0x42020830 : FFFFFFFF It looks like it only reads the value from 0x42020800 (the first word).It works fine on the F103 so i am guessing it has to do with the protection on the H523.The option byte is ED (open). What can I do to make it work? KetilO

I'm trying the program an STM32G0B1RET with the STM32CubeProgrammer. It seems the programmer sends a 0x7f and the MCU responds, but maybe too late to connect? 

I have a customized pcb with stm32l476 as the mcu and stm32f103 as  a debugger. Since my debugger is not flashed i am using an external st-link from the nucleo-l476. When i try to connect it in the normal mode and reset mode, STM32 Cube Programmer gives me an error that DEV_TARGET_HELD_UNDER_RESET and when i try to connect it in hot plug mode, it connects but gives an error that NO DATA READ. What should i do?

Hi,Yesterday I found on YouTube a video from ST that showed how to read firmware from(!) an STM32 board to a pc using STM32CubeProgrammer. Today, I cannot find that video. Could someone from ST please point me in the direction of that video ? Thanks. Stuart
