STM32CubeProgrammer (MCUs)

Hi every one,I read bin/hex file from stm32f103c8 MCU and saving it, then I erase the MCU and burning the same bin file which I read in the previous stage, the MCU does not work as before.can you help me please

Hi,I have a situation where I can successfully program the target using STM32CubeProgrammer, but it fails when I try to do the same with STM32_Programmer_CLI.exe with an error:Error: failed to erase memoryBoth are v2.13.0.The command line I used:STM32_Programmer_CLI.exe -c port=SWD -d "firmware.bin" 0x08000000 -vb 3Attached are the verbose level 3 output from each. I am attempting to figure out why STM32CubeIDE fails to download code for debug. It also encounters the same failed to erase memory error. Appreciate any help anyone can give me. Thanks.

Hi  I am having issues with programming a target board with a genuine ST-Link board (got from Farnell) . I have been using a cheap programmer that works, and as I have upgraded to the new IDE (from atollic) it fails to work , but still works on the STM32CubeProgrammer. The genuine ST-Link communicates with the PC, but cant connect to the Cube Programmer, while the cheap one works perfect. I have set the ST-Link Configuration to the below.I also have the images from the logic analyser during a connect sequence. As this is on the same target board and the cheap one work, I think this points to an issue with the genuine programmer. I managed to get a loan of another genuine one, and that too has the same effect. A noticeable difference the serial clock starts before the Reset line goes low , unlike the genuine no clock  till a good while after the reset line , and I assume it times out before this. Anyone any idea, I am totally baffled. I checked all the voltages on the board an

Hi  I have been using Atollic for years , with the cheap stlink programmers from AliExpress. I havent had any issues, but just recently updated to STM32IDECube (V1.13.0) , and STM32CubeProgrammer (V2.14.0) . I purchased an original ST32Link-V2 , but unfortunately doesn't connect through either STM32CubeProgrammer  or STM32IDECube. The cheap version works on STM32CubeProgrammer but not STM32IDECube , comes up "error No ST-Link Detected " (same error STM32IDECube for genuine).  I am using pins:SWDIO , SWCLK , GND . I also tried the Reset line on the genuine , but still error. On STM32IDECube  I get "No ST-Link Detected.." on both the cheap and genuine one. On the STM32CubeProgrammer  works as expected with the cheap one, with the genuine one I get error DEV_TARGET_HELD_UNDER_RESET if I attach the reset line, and no STM target found error without it. I have the RST line on the processor pulled up with external 10k, and BOOT0 pin pulled low with 10k. I go

I am working with a NUCLEO-WB15CC, and it seems that I can't read or write anymore. When I connect via ST-Link in STM32CubeProgrammer (v2.14.0) I just get Error: Data read failed When I try to read registers, I get the same error.I also can't erase the chip: Error: Mass erase operation failed.Please verify flash protection RDP option byte is AA, so that can't be the problem.For write protection, I don't really remember what the default values was, but they are: 0xff, 0x0, 0xff, 0x0,I can still see target information in Programmer but nothing else seems to work, have I bricked the chip? Edit: I noticed I also can't read registers via the CLI, so maybe it's not a bug in STM32CubeProgrammer.This is the command I used: STM32_Programmer_CLI.exe" -c port=SWD -r32 0x08000000 0x4 Which results in Error: failed to read the requested memory content Read protection seems to be disabled:Here are all the option bytes:OPTION BYTES BANK: 0 Read Out

STM32F446, locked to RDP1, BOR set to 3 is incorrectly read out/displayed [EDIT] see next post [/EDIT] in CubeProgrammer v2.12.0:The same chip read out by STLink Utilities:Note, that the write protection is read out/displayed correctly (although very confusingly differently) in CubeProgrammer.I'd also add a recommendation/change request: similarly to STLink Utilities, read out current Option Bytes when OB are to be displayed for the first time [EDIT] this appears to be done when connection but the recommendation to add to level-1 log holds [/EDIT]  and add a line to the level-1 log that you've done so.JW

Hello all,I'd like to know if there is a set of acceptable UART baud rates for CLI use (CubeProgrammer CLI defaults to 115200 baud for UART).Looking at the GUI for CubeProgrammer, after selecting UART, it shows that a baud of 460800 or 921600 is possible, but only a baud of 460800 worked with the CLI, but 921600 timed out (I think.. the window closes very fast, as we're 'calling' the CLI from within a Python script).Any help would be appreciated. 460k baud is still much faster than the default, but if I can push the limits with 921k, I'd be happier :)Thanks!

When loading a .hex file into flash, the STM32CubeProgrammer (v 2.13.0) miscalculates which sectors to erase and as a result, the download often fails unless the region being loaded has been previously erased or happens to contain the same values.For example (see attached image), when loading an image that is 0x23B74 bytes (142.86KB) bytes to address 0x08004000 in an STM32L471 (256 x 2K sectors), it erases sectors 4..39. The start sector for address 0x08004000 should be 8 (8 x 2048 = 0x4000) and the end sector (0x08004000+0x23B74=0x08027B74) should be 0x4F (79 decimal)If I'm doing something wrong, suggestions would be appreciated!

I see a FAIL.txt file in the mass storage that says "The interface firmware FAILED to reset/halt the target MCU".LD1 and LD3 are red.I cannot even load the simple programs like Blink LED using any IDE.The on-board F401RE chip is quite hot. Dropping a bin file doesn't help either. Nothing is running on it.It was working perfectly 2 days ago and I don't know why it doesn't work anymore.Any help or suggestions will be appreciated. I included some photos for reference.P.S. I tried STMCubeProgrammer but that doesn't connect either.

Haven't found anyone talking about the new API here. I'm trying to code a program that flashes a STM32F334, reads processor's UID and post it to a proprietary database. STM32CubeIDE and CubeProgrammer works fine. I also managed to run C++ API and identify the STLink probe, but it doesn't connect to the device.​When trying to connect to device via C++ API, I get this error:STM32CubeProgrammer API v2.5.0 STLinkUSBDriver.dll loaded STLinkUSBDriver.dll loaded STLinkUSBDriver.dll loaded ST-LINK SN : 0676FF505150807567112946 ST-LINK FW : V2J36M26 Board : NUCLEO-L053R8 Voltage : 0.01V SWD freq : 4000 KHz Connect mode: Normal Reset mode : Core reset Error: Unable to list supported devices Error: Cannot identify the device Establishing connection with the device failed Disconnected from device.​I'm running on MacOs 10.15.6.

Dear @KDJEM.1 when I read the manual "rm0432" It is given thatThe Flash memory programming sequence in standard mode is as follows:1. Check that no Flash main memory operation is ongoing by checking the BSY bit in theFlash status register (FLASH_SR).2. Check and clear all error programming flags due to a previous programming. If not,PGSERR is set.3. Set the PG bit in the Flash control register (FLASH_CR).4. Perform the data write operation at the desired memory address, inside main memoryblock or OTP area. Only double word can be programmed.– Write a first word in an address aligned with double word– Write the second word5. Wait until the BSY bit is cleared in the FLASH_SR register.6. Check that EOP flag is set in the FLASH_SR register (meaning that the programmingoperation has succeed), and clear it by software.7. Clear the PG bit in the FLASH_SR register if there no more programming requestanymore.My code isuint64_t data=0x1234567890ABCDEF;HAL_FLASH_Unlock();HAL_FLASH_Progr

Hi all, i have a MC, ie STM32H745IIK6(Dual Core). i need to program/flash it using STM32_Programmer_CLI tool. tried bellow mentioned command."./STM32_Programmer_CLI -q -c port=SWD mode=UR -e all -w /home/usr/workspace/BinaryFiles/example.bin 0x08000000 -v --start"after executing this i am getting a warning "The Core is locked up" and MC not executing any instruction.If any one have some idea regarding this issue please let me know.

Does the STM32 ST-LINK utility work with Windows 11??

I'm new to stm32 programming, but have experience with other complex low level drivers. I'm looking for ideas because I'm confused by this issue.I hired a contractor to write code to view a few sensors, monitor a few rotary encoders, and use a 320x240 1 bit lcd using SPI (he used the lvgl library for this) since I'm not familiar with stm32.This seem to work pretty well on his system. However, when I load his hex file (or build it myself) it runs around 100x slower, and has a few other minor issues that don't seem related to performance, but maybe they are? It mostly works, like the encoders are working, sensors are giving reasonable values, but one encoder doesn't work and the fps of the screen is about 0.3 instead of 30. I've seen a video of his device and it works well.We both have multiple programmers (I'm mostly using the official st link v3), and both have multiple copies of the pcb with the stm32 chip.I did use HAL_RCC_GetSysClockFreq to check the frequency and it reports the cor

Dear All,I'm looking source code of STM cube programmer for Custom changes as per my Application,Kindly suggest how to get source code of cube programmer(Uart programming mode)  

Dear @KDJEM.1 Whenever, I implement the HAL_Interrupt functions(say HAL_UART_Receive_IT();). What is happening at the backend, to use those interrupt function I should enable the global interrupt (NVIC) in CubeIDE. What are these global interruptsalso can we say callBack functions as ISR,s ? 

I need to load a few small audiofiles to the flash memory of STM32F407VGT6 on my F4Discovery board and now I am curious about one thing. Is it possible to load WAV samples with STM32CubeProgrammer?For example, if I use xxd command in Ubuntu to convert wav to bin and after load this binary file to the flash memory sector by changing start address and skipping flash erase, will it be possible to play the sound from the uploaded data further?

Hi, I'm having an STM32L4P5.In sectors [0 7] there is a bootloader, in sectors [8 75] the application is located.With STM32_Programmer_CLI.exe  I can issue an erase for specific sectors and it seems to work. But STM32_Programmer_CLI.exe wants to programm all the time beginning with sector 0. That doesn't matter for the bootloader, but programming the application overwrites the bootloader. --skiperase is not an option, because STM32_Programmer_CLI.exe still tries to programm the application at sector 0, and since it isn't erase, it fails.I would need an option for excluding sectors from programming. TxMatthias

Hi, I found a bug in stm32cubeProgrammer version v2.13.1. When you try to readout unprotect an STM32H7A (without smps) and if its rdp level is set to 1, that didn't works. I have to unlock it manually inside my software.  

Hello,STM32CubeProgrammer 2.13 has some bugs:See attached picture, the Target information does not report the correct flash size, although it is reading the memory size correctly at 0x1FFF75E0Why does it have to read multiple times in a row the same information ?When using an external loader, the "Deselect all" button does not work, clicking on it does nothing.Also with the external loader for an I2C EEPROM, you can't fill memory (of any size) at an unaligned address, even though nothing in the EEPROM prevents it.Best regards,Kraal

Hi,I am using STM32U575 MCU in my project.I had enabled trustzone and using secure and non-secure memory.I am successfully able to download my secure/nonsecure images into MCU using IAR, But when i download using STM32CubeProgrammer.exe or from STM32CubeProgrammerCLI.exe, it fails in verification.when i debug further i noticed that first nonsecure address never get write/verify successfully.Note: When i configure the entire memory as secure for testing using OPTIONBYTE_WMSEC, i am able to write my non-secure image as well.Please guide me, is there any option to write non-secure image using STM32CubeProgrammer with out altering option bytes.Thanks in Advance !!
