STM32CubeProgrammer (MCUs)

Hi,I'm facing something strange.I'm trying to program a STM32U5G9 (disco board).It was a success, but since I've updated the cubeProgrammer Tool it's not working anymore.I'm trying to program a 935kB binarie file.According to the log file, CubeProgrammer erase the 62 first sectors (62 x 8 kB = 496 kB ==> 0x7C000) and start to write.During the verifying phase, it fails @ 0x0807 C000, corresponding to the start of flash (0x0800 0000) plus the offset previously mentionned.Checking the memory with the "Device Memory" view in CubeProgrammer, I see that the memory is not the right one.What is strange, is that it happens after I update the cubeProgrammer (from 2.11 I think to 2.18)The same happens on CubeIde after an update.Everything is fine if I do a mass erase before writting, but as I am using a virtual Eeprom on flash (package en.x-cube-eeprom-v7-0-0) I don't want to erase completely the flash, otherwise, I'm loosing datas.Anyone facing the same behaviour?Thanks.  &nbsp

STM32CubeProgrammer v2.13 was giving me the famous "Failed to execute MI command" and "Failed to download Segment[0]" errors within the STM32CubeIDE, so I downloaded the standalone STM32CubeProgrammer v2.10 and it works fine. The IDE still uses v2.13, so how do I downgrade that one to v2.10 so I can program my chip through the IDE?

Hi all, I am working on my own program using the API provided with the stm32Cubeprogrammer V2.18 to flash custom bootlader and programs over USB in dfu mode. The problem I had was when I tried to flash a custom bootloader, the function connectDfuBootloader threw this error: Error: Database cannot be found. DatabasePath = /../Data_Base/STM32_Prog_DB_0x415.xml Error: CUBEPROGRAMMER_ERROR_NOT_SUPPORTED After a few attempts I realized I had to put the Data_base folder 3 folders up from the executable file so the program can find that file. This is not a major problem but I can't find any function within the API that allows me to change that path, so do anyone knows another way to change this?ThanksKind regards   

Hello, I am trying to configure RTC time and date register from STM32CubeProgrammer CLI but as for now I am facing issues only. I was wondering if there's some special procedure to edit these registers straight from the programmer or not, since I am trying to replicate what's written on RM0456 to edit calendar values.I made a simple C# console application:uint RTC_REG_TR_BASEADDRESS = 0x46007800; uint RTC_REG_DR_BASEADDRESS = 0x46007804; uint RTC_REG_WPR_BASEADDRESS = 0x46007824; uint RTC_REG_INIT_BASEADDRESS = 0x4600780C; RunCmd($"{CLI_EXEC_PATH} -c port=swd dLPM mode=UR -hardRst -w32 {RTC_REG_WPR_BASEADDRESS} 0xCA"); RunCmd($"{CLI_EXEC_PATH} -c port=swd dLPM mode=UR -hardRst -w32 {RTC_REG_WPR_BASEADDRESS} 0x53"); RunCmd($"{CLI_EXEC_PATH} -c port=swd dLPM mode=UR -hardRst -w32 {RTC_REG_INIT_BASEADDRESS} 0x80"); Thread.Sleep(1000); RunCmd($"{CLI_EXEC_PATH} -c port=SWD dLPM mode=UR -hardRst -w32 {RTC_REG_TR_BASEADDRESS} {RTC_REG_TR_VALUE}"); RunCmd($"{CLI_EXEC_PATH} -c port=SWD dL

I am programming my STM32F423RHT6. But due to some reason, suddenly I am unable to code the MCU. The connection is getting lost for some reason. I don't know what is the reason for this behavior.  I am attaching my code along with this message. The debugger which I use is an external debugger of stm32. I tried changing TCXO, tried changing the same CHIP. Voltage levels are as per the data sheet. For the 1st few times of programming, am able to flash the code. But after couple of times, facing this issue. Note:I kept programming for peripheral by peripheral and this issue happened suddenly all at once. After finalizing the product and manufacturing parts and soldering, I am facing this issue. Kindly help me out.Is my chip being dead after few instances of programming?

 Hi @Igor Cesko I am experiencing connection issues with STM Cube programmer when connecting ST LINK debugger.The controller part number i am using is STM32G491MCT.Getting "Error Target device held under rest", I can connect only if I change the ST link configuration to Hotplug mode.Even after connecting sometimes it shows "there is no active configuration".I am unable to program the controller.Kindly help me to get resolve with the issue as early as possible.       

Hi, We are trying to write some key values directly into a particular address of NVM from STM32Cubeprogrammer, but rest of the sector are also getting erased. Is there any way to prevent it? Tested with Cubeprogrammer CLI also, but facing the same issue.

Using an STLINK-V3PWR, I can connect to the device in Normal, Under Reset, and hwRstPulse modes, but when I select Hot plug mode, I get an error "No STM32 target found." I've been tasked with trying to connect to this board without resetting it, but am at a loss about where to start with troubleshooting. I've tried changing various other configuration settings, but have not found anything that will allow hot plug connection.

Hi!I am currently developing an application using the LVGL library. Since I’m working with a display, I need extra memory to store all the data. To address this, I acquired a display module from Riverdi (based on the STM32H747xx), and they provided me with an .stldr file to program the QSPI flash.However, I am not using STM32CubeIDE because I prefer not to work with it. Instead, I’d like to use STM32CubeProgrammer to load the .stldr file and program the QSPI flash.My question is: how can I properly use STM32CubeProgrammer with my custom .stldr file to program the QSPI flash and my program at the same time?The stldr file is for communicating with the flash through the debugger? Thank you! 

Hello! I have tried to download the STM32CubeProgramme in Firefox, Edge and Chrome, and when i try to get the software the html of buttons to donwload are broken, nothing apear, and i don't know what to do anymore, i need this to flash my firmware, the official link: https://www.st.com/en/development-tools/stm32cubeprog.html, exist another link? SourceForge or some alternative that i can trust to donwload it?  

Hi,i am able to find function that i have in my code in the build analyser, but not all of them. Neither with the map, elf or bin file. I even restarted my PC.I used the search function in the build analyser. I found some "xxx.o" and "*fill*" "functions" though.

I have just purchased a STM32H573I-DK Discovery board, only to find it doesn't appear to recognise the ST-link V3.  Is this a true problem, or just me, and is there a solution?

System: Macbook Pro M2 OS Ventura 13.4.1 and ST-Link Server 2.1.I can't access the serial port of the STLink nor with the ST32Programmer because it doesn't recognize the STLink correctly. On my Intel Mac with OS Ventura there are no problems.Does anyone know a solution , thanks in advance

We would like to programm an external Flash connected to an STM32U575 with STM32Programmer v2.18.0, ST-Link V2 and a self made ExternalLoader. When we use sector erase and erase all with STM32Programmer CLI it reports success, but nothing happens on the external Flash. It seems that the CLI ignores the external loader and the internal Flash of STM32U575 is cleared.The read command seems to work and you can see in the Log-Files that the Read-Function from our external loader is called (Line 116 read.txt). Log-Files are atteched.We use the following command:  Mass Erase C:\DevTools\STM32Cube\STM32CubeProgrammer\bin>STM32_Programmer_CLI.exe -c port=swd -el ExternalLoader\test.stldr -e all -vb 3 Sector Erase C:\DevTools\STM32Cube\STM32CubeProgrammer\bin>STM32_Programmer_CLI.exe -c port=swd -el ExternalLoader\test.stldr -e [0 1] -vb 3 Read C:\DevTools\STM32Cube\STM32CubeProgrammer\bin>STM32_Programmer_CLI.exe -c port=swd -el ExternalLoader\test.stldr -r8 0x0 0

I'm trying to interact with the external flash on the STM32H573I-DK, and having some issues. I'm using the `MX25LM51245G_STM32H573I-DK-RevB.stldr` external loader.Using the J-Link, I can read the flash and erase sectors, but the program immediately crashes when I try to program a file.

Hi,I am working on STM32G491KCU6 board.We are connecting STM to a linux based SoC via SPI. What we required is, we need to flash STM from SoC. We found stmflash binary which supports only through i2c and UART. Is there any tool that support flashing via SPI?

Hello,In one of my boards I was planing to use CANBUS bootloader and STLink V3 with external canbus PHY to program MCU.I was unable to program it, I can see STlink V3 does try to do some TX on CANBUS pin, but where is no packet available that could be decoded, just train of same duty cycle pulses.Does any one had luck with STLink V3 and external CANBUS programming ? What I am doing wrong ?Yes, I added external TCAN1462VDRBRQ1 IC for programmer, and connected to RXD and TXD pins on STLINKV3_MDOS (RX 9, TX 10pin)Yes, I enabled externally TCAN1462VDRBRQ1 to be in active mode all the timeYes, I placed BOOT0 pin to high level when connecting power (same pin for power and BOOT)YES, STM32U585 uses PB8+PB9 as per datasheet for canbus bootloader 

Hi,i have an issue, where i implemented using DMA. The DMA works seemingly without issues, but when debugging and using the start/pause buttons, the hard fault happens.Would the be a smart way to *simulate* a pause/start of a debug session??EDIT:I found out, that this issue only happens when the interrupt is activated: volatile uint16_t adcArray[12] void DMA1_Channel2_IRQHandler(){ ADC_TEST_2_ON // Transfer complete if( READ_BIT(DMA1->IFCR, DMA_IFCR_CTCIF2) ){ DMA1->IFCR |= (DMA_IFCR_CTCIF2); // Clear bit transfer complete // tempFETBits = 0; // battVoltBits = 0; // throttleBits = 0; // buttonSensBits = 0; tempFETBits = adcArray[0]; ADC_TEST_2_OFF; } // Transfer error if( READ_BIT(DMA1->IFCR, DMA_IFCR_CTEIF2) ){ DMA1->IFCR |= (DMA_IFCR_CTEIF2); // Clear bit //TODO: save event while(1); } ADC_TEST_2_OFF; } 

Ive been trying to use the FDCAN systembootloader from a stm32H757XI, in the past i managed to use the CAN systembootloader from a stm32f405RE succcesfully. But im getting> nothing , i tried with 125 and 250Kbauds, CAN connceted to PH14 and PH13   Is FDCAN systembootloader compatible with STLINKV3+CubeProgrammer?

Is FDCAN Systembootloader described in AN5405supported by cubeProgrammer or the CLI tools?Because i only see the CAN (classic) option 

Hi there,I have an ST-Link V2 which i want to use for programming a .bin file to an stm32G0 MCU. Afterwards i want to set the RTC register to the time beeing. It already works "manually" but i wanted to write a script to automate the process.I already managed to script an automated RTC register setup, but the script needs the ST-Link to run with the libusb driver.Now i wanted to automate the .bin file programming with the CubeProgrammer CLI, but i can't connect to the St-link when using the libusb driver. To make things more confusing, i can still connect with the CubeProgrammer GUI when setting the option shared to enabled. After some reading of the docs i also managed to get the probe listed on the CLI when using   -l stlink-shared  It gives the following output:   ------------------------------------------------------------------- STM32CubeProgrammer v2.18.0 ------------------------------------------------------------------- ===== STLi

Hi, I'm making a board for UART and I2C communication.Please refer to the schematic below;  I put 5V External power supply at VBUS,and connects SWDIO, SWCLK, NRST, 3V3, GND to the STLINK V3 Minie. However it shows "No STM32 target found" message on STM32CubeProgrammer when I clicked "Connect" button.Since the "Target voltage" shows 3.31V, I think there is no power problem.Is there something that I missing?Please let me know.Thank you.

Is it possible to save the current GUI setting settings (e.g. file names and path, start address, erase option, ST-Link config)?
