STM32CubeProgrammer (MCUs)

Hi All,I have STM32H747I-DISCO board with a built-in STLink-V3E. I am trying to falsh the MCU, but no matter what I do, I cannot get STM32CubeProgrammer 2.5.0 to recognise the board.I plug the board into Win10 PC via a micro-USB cable in the ST-Link-V3E socket (CN2). The board powers up and displayes demo software that came with it. JP6 jumper is set to STlk.I fire up STM32CubeProgrammer 2.5.0 which says "No ST-link detected".I have installed STLink009 drivers, however, I also don't see the board under the "USB Composite divce" list in the Device manager.Is the board faulty or am I doing something wrong?Thank you!

Hi all, I have been looking for sometime now but I can not seem to find a link to a bug tracking system where I can report issues that I am facing with STM32CubeProgrammer or Micro-controller. The community has been helpful but it would be good to have a system where issues can be officially reported and becomes St-microelectronics responsibility to deal with rather than waiting on the generosity of the community member who themselves may be struggling with time for their own projects.

STM32CubeProgrammer not clearing the Option Bytes on STM32H7B3i-DK. I can not load any code.Is it possible to clear these bytes with STM32CubeProgrammer and if so how? Below is the error that I am getting.13:58:53 : Time elapsed during the read operation is: 00:00:00.002 13:59:39 : Option byte command : -ob PROT_AREA_START1=0xff DMEP1=0 DMEP2=0 PROT_AREA_START2=0xff SEC_AREA_START1=0xff DMES1=0 SEC_AREA_START2=0xff DMES2=0 13:59:39 : PROGRAMMING OPTION BYTES AREA ... 13:59:39 : Bank : 0x00 13:59:39 : Address : 0x5200201c 13:59:39 : Size : 308 Bytes 13:59:39 : UPLOADING OPTION BYTES DATA ... 13:59:39 : Bank : 0x00 13:59:39 : Address : 0x5200201c 13:59:39 : Size : 308 Bytes 13:59:39 : OPTION BYTE PROGRAMMING VERIFICATION: 13:59:39 : Error: Expected value for Option Byte "DMEP1": 0x0, found: 0x1 13:59:39 : Error: Expected value for Option Byte "DMEP2": 0x0, found: 0x1 13:59:39 : Error: Expected value for Option Byte "DMES1": 0x0, found: 0x1 13:59:39 : Error: Expected value for Option

HiWe are Using a STM32H755IIT6 for the aplicatin. Now we are using USART1 on PA9,PA10 as Debug and Boot loader Interface. If we are in Normal Operation and the GPIO are configured we are fine and everything works as expected. As soon as we enter the boot mode (setting Boot Pin and Reset) the STM Qube Programmer notice the MCU and we can write the SW. The problem is during the time the Boot loader is active the PB14 pin is driven High. This is very unfortunate because we have a Buzzer attached to this pin.Is there a way to prevent PB14 to be driven?Thanks

I have few devices With STM32F0xx which are connected via usb to linux hosts. In order to get necessary functionality I have to swap their firmware. Given that they are connected to linux I used first ‘dfu-util’. While tool itself completes process devices are stuck in DFU mode. Flashing process reports no issues, devices after restart report invalid firmware.The same firmware can be updated from Windows STM Programmer. I downloaded STM Programmer for linux to check update with official tool. Result are same as for dfu-util - update doesnt work.Issue is quite annoying cause I have no ways to determine what went wrong on STM side. All I have is USB connection and dfu mode.Below is command I used to execute update:/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer.sh -c port=USB1 -e 0 -d ~/Downloads/uccb/0303.hex 0x08000000 -vb 3 -rstFirmware I am testing is open source, it is available online:https://github.com/UsbCANConverter-UCCbasic/UCCBEmbedded/releaseshttps://github.com/UsbCANConv

Hello guys,​Recently, my ST Discovery F407 board was working just fine, until I received the following error in a txt. File: ​the interface firmware failed to reset/halt the target mcu.​I have updated its frimware to​ 2.37.26, but the problem is still there. I have also tried to reset through connecting Boot0 to VDD, but it didn't work either. Still, I receive the same error each time I connect it to the PC. The Keil program is also saying "target is not connected" every time I try to download my code.​I would be so much thankful if you help me with this!

Hi,Not sure what I am doing wrong but when I program my STM32H7B3I-DK board with STM32CubeProgrammer, all seems fine, the application start to run and everything is okay.The problem occurs when I click the Disconnect button and later then try to Connect at this point what everything I have programmed in the flash memory of device gets erased.I am running the Secure Boot Secure Firmware Update (SBSFU) example program. Below is an image of my "Option Bytes" I can't see any of the flag to cause this behavior.

Hi everyone, I recently got a Nucleo board (STM32L476RG) to introduce myself to the stm32 mcu and I've installed the stm32cubeide alongside it. I've been trying to run a simple blinky project for the past hour but I keep getting this message, "Waiting for debugger connection... Debugger connected... Debugger connection lost... Shutting Down..." Has anyone encountered this problem before?Thanks

When I program my STM32H7B3i-DK board with STM32CubeProgrammer the firmware starts to run immediately. If I power cycle the board the firmware no longer runs.In other words the firmware would not run after a power cycle.

Hi All,I am trying to program a STM32L152R8 MCU with stm32cubeIDE v1.4. The MCU is not brand-new and is soldered on a board. I want to change its firmware. While debugging with ST-Link Debugger I encounter the following error:-------Memory Programming ...Opening and parsing file: ST-LINK_GDB_server_a07132.srec File         : ST-LINK_GDB_server_a07132.srec Size         : 9052 Bytes Address      : 0x08000000 Erasing memory corresponding to segment 0:Error: Flash loader cannot be loadedError: failed to erase memoryEncountered Error when opening E:\ST\STM32CubeIDE_1.4.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_1.4.0.202002181050\tools\bin\STM32_Programmer_CLI.exeError in STM32CubeProgrammerDebugger connection lost.Shutting down...------Notes:The reset pin is connected,I've tried to mass erase the chip using st-link ut

I've been trying to use TIM1CH2N to generate PWM to control ws2812b RGB LED. I have got one working library for TIM1CH2, but I'm unable to generate the same signals in the CH2N pin (STM32H750VB)​. Can anyone help me out to resolve this issue?

The STMCubeProgrammer would no longer connect to my target. I was able to create a simple test program with Keil toolchain and step through the code and suddenly I noticed that the board stopped responding.I then tried connecting to the board with STMCubeProgrammer which I have always used as a sanity checker for my boards.The board has no external devices connected to it so I can't understand why this should happen.Please any suggestion on how to resolve.

I am using STMCubeProgrammer in USB DFU mode to change from RDP Level 1 to 0 (using command line -rdu option). This nukes (mass erases) all flash and all "backup SRAM" (according to datasheet).My product has a couple of bytes of custom config data stored in flash, which of course gets nuked. Is there ANY way to save this config data, such that I can put it back into flash after I'm done changing RDP to 0?I tried:writing my config data to known location in regular sram, then jump to DFU mode, then use STMCubeProgrammer to change rdp 1->0, then read the SRAM. But that gets nuked too, either by the bootloader, or hardware when rdp1->0.

I have a custom board with one STM32H743ZIT6 (“Control MCU�?) and six STM32H7V43VIT6 MCUs. The idea, eventually, is for the Control MCU to reset the six slave MCUs.Right now, after an initial flashing of the slaves with a “bring up�? blinky program they run after reset. However, I cannot now flash anything to them. For example, in SW4STM32 Workbench on my MacBookPro ….With the debug cfg file with “Connect under reset�? or “Hardware reset�? or “Software system reset�?, I get STLINK_SWD_AP_WDATA_ERROR and auto_probe failed errors in the console.So, I now have STM32CubeProgrammer installed, version 2.5.0. Besides it’s randomly crashing from time to time, when it behaves, I cannot connect to any of the slaves. CubeProgrammer gives the error: “Error: No STM32 target found!�?BTW, each slave MCUhas a 10-pin JTAG connector properly wired up (3.3V from the board, GND, SWCLK, SWDIO, SWO, RST). I have done connectivity tests along the route from the ST-LINK/V2 module all the way to the 10-pin hea

Hi,I am experiencing a problem with STM32CubeProgrammer: it fails to program STM32L0s MCU when the size of the file to program is not a multiple of 8.In the attached zip file, there are 2 .bin files containing 16 bytes of zeros (working.bin), and 20 bytes of zeros (failing.bin), respectively.The first one can be programmed to the FLASH of an STM32L0 with STM32CubeProgrammer v2.3.0 without problem, but the second file fails with the following error :10:32:42 : Memory Programming ... 10:32:42 : Opening and parsing file: failing.bin 10:32:42 : File : failing.bin 10:32:42 : Size : 20 Bytes 10:32:42 : Address : 0x08000000 10:32:42 : Erasing memory corresponding to segment 0: 10:32:43 : Erasing internal memory sector 0 10:32:43 : Download in Progress: 10:32:44 : Error: failed to download Segment[0] 10:32:44 : Error: failed to download the File 10:32:44 : Time elapsed during download operation: 00:00:01.648Other possibly relevant information :The problem occurs when STM32CubeProgrammer runs u

Programming bank2 of an STM32H743 starting at 0x0810000 leaves a section unprogrammed between 0x08100040 and 0x08100800. Programming bank 1 works fine.Using the UI and the CLI version 2.4.0 via the UART. I'm pretty sure I don't have any security bits set. What am I doing wrong? My own flash routine in my boot code in bank 1 programs it fine.

Hi, i downloaded STM32CubeProgrammer and it seems CubeProgrammer_API library is x86 compiled. Is it possible to have CubeProgrammer_API library x64 compiled?ThanksFabio

I want to update the FW to H7 MCU via its USART by embedded bootloader. It seems need to control the BOOT0 pin and nRST pin when the MCU is in normal running. By CubeProg tool, how to control above 2 pins by PC? Usually, I will build a USB to UART bridge chip for this purpose.One thing that I can not understand well at the monment: is such a bridge chip specified by CubeProg tool or free chosen by user? I think this also related by GPIO(flow control pin) control of bridge chip.

I am using gnu tool chain and am trying to build an image for the Nucleo F072RB board.It all looks good, the only problem is that the map of the image looks as follows:08000000 t deregister_tm_clones08000024 t register_tm_clones0800004c t __do_global_dtors_aux08000078 t frame_dummy080000b4 T _mainCRTStartup080000b4 T _start...persumably _start is the entry point of the program, but it is not at the beginning of the image when elf is converted to binary, so the program is not going to be started properly.Or maybe a more open question: is there some tutorial on how to build executable images for flashing for the Nucleo board. I searched the ST site - information is related to various IDEs, but nothing for Linux command line.TIA!

Hi,I recently stumbled on a issue.For a project we developed a bootloader which checks the programs CRC if it matches and halts if not. The CRC is calculated after linking and is placed in front of the application.I found out that there is a difference between the compiled binary (.bin) file and the programmed target when programming through STM32CubeIDE. This makes the CRC calculation fail.The difference seems to be in the blank (unprogrammed) areas.STM32CubeIDE uses STM32CubeProgrammer CLI to program an SREC format file.This SREC format may contain areas which aren't programmed.ARM GCC converts an ELF to binary and fills unused areas with 0x00.STM32CubeProgrammer 'fills' unused areas with 0xFF.Attached are simple examples.We have an reproduce.srec which writes the ASCII 'test' multiple times. Address 3D, 3E and 3F are not programmed.When converting reproduce.srec to gccoutput.bin with ARM GCC:arm-none-eabi-objcopy.exe --input-target=srec --output-target=binary .\reproduce.s

Hi. I am trying to program my stm32F072RB using the build in boot loader. I connect the user USB to my PC with BOOT0 pulled high and sure enough it does detect a dfu device. (the serial number looks fishy though?)Now if i try and connect it prompts me to disable read protection. which it does sucessfully. but then it disconnects immediately afterwards and if i try again. it will just do the same. I think it is a driver issue but i have allready tried to change the driver using the zadig method described in other threads. with no luck.I have hit a dead end here. hope someone can help me figure out this mess. if you need more info pls. dont hesitate to ask.

Hi, I have a question about QSPI flash loaderI am currently using Custom External Loader for QSPI flash with STM32H753and at first it looked like working well, but found out that there are some issues.One of issue is reading a qspi memory by memory mapped mode, and it looks like the reading on the CubeIDE and CubeProgrammer is different.As you can see the pictures below, I wrote 0x0A to from the address 0x91000000 to 0x91000100 and so on.the first one is the result that I want, but the second one is not.   What I want to do is writing a binary from the Cube Programmer and reading it from the STM32H753, but when I tried to do this, this time, the reading from cubeIDE is not aligned, So I have no idea, which one is wrongly configured, even though the configuration code is same. Does anyone have idea about this?I found out if I change the dummy cycle to the 12, it seems like the byte align is moving.Thanks in advance.1) reading on CubeIDE2) reading on Cube Programmer
