STM32CubeProgrammer (MCUs)

Edit: This error is fixed in STM32CubeProgrammer v2.11.0. Just update.I have written a custom external loader for our H7 board. It can access QSPI flash that is connected to an H7 MCU that is connected with SWD to an STLink. Most seems to work, but read from the external flash is limited to approximately 100 kB. The same problem can be replicated on STM32H735G-DK. I use STM32CubeProgrammer v2.5.0.I have used this command to read the external flash:STM32_Programmer_CLI -c port=SWD -el /usr/local/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/ExternalLoader/MX25LM51245G_STM32H735G-DK.stldr -u 0x90000000 0x30000 ./temp.bin -vb 3It initializes the external loader to enable memory mapping and reads:r ap 0 @0x90000000 0x0001B000 bytes Data 0x00000025It reads only 0x1b000 and not 0x30000 that I wanted. Without verbose it shows a percentage and then success.The resulting file is 0x30000 big, but contains only 0x1b000 of data and then is filled with zeros.If I read another chunk with an o

Hi! I'm searching a way to exit from the builtin bootloader after having successfully programmed my flash from USB. Is it possible to jump to my program in flash if I continue to hold the boot0 pin always high? I have done some attempts using STM32_Programmer_CLI.exe specifying the start address (option -s from command line) to my ResetHandler function which is in flash at address 0x8000970. It seems that this doesn't work and it needs to switch boot0 pin at a low level to make it works.Just to explain my setup: I'm using the STM32_Programmer_CLI.exe program as following:STM32_Programmer_CLI.exe -c port=USB1 -w myprog.bin 0x8000000 -s 0x8000970Do you have any suggest? Thank you!

I'm working on making a custom PCB using an STM32L5xx board field-updatable. To that end, I've configured the option bits according to pattern 12 from AN2606:TZEN = 0, nBoot0(bit) = 0, nSWBoot0(bit) = 0, NSBOOTADD1[24:0] = 0x017F200.With this setup, the microcontroller will always start and reset to bootloader mode, which I do think is a good thing for now. It should help protect against the a problem in application mode bricking the microcontroller and needing to use a debugger to fix it.I've been using the NUCLEO-144 L552ZET6Q to test/debug this method. When the uC is in bootloader mode, the red and blue user LEDs turn on, and switching back to application mode will turn them off.To switch to application mode, I've tried to use CubeProgammer CLI to start the application mode, which it does seem to do, only for it to be forced back into bootloader mode.If I try to run this via USB DFU, it looks like it has the same effect, with the difference of there being an error in the DFU (likely

Hi, I'm wanting to know if the STM32 Cube Programmer is considered a production tool suitable for programming at the point of manufacture/assembly during production, please? Regards, Rab

Hello!I'm trying to use the embedded bootloader on STM32F042K6T6, by UART protocol, but no luck yet. I'm using USART1 pins (PA9/PA10) and BOOT0 to a button and 3v3, so I press this button and power on my board. On STM32CubeProgrammer, I've selected my UART to USB converter (pullup on RX line) COM port and after clicking "Connect" on software, there is a response from target but it didn't go on: Am I missing anything?Thanks!

We've got a bizarre Hard Fault on STM32L452. It happens immediately after reset, and ONLY after programming our bootloader with the CubeProgrammer after doing a full chip erase. If one subsequently programs the bootloader again using the same hex file but not performing the full chip erase, the problem will vanish and never return until the full chip erase sequence and programming sequence is repeated. And it doesn't always happen. It's plaguing us. It feels like a tool issue, but until we understand, it is very worrying.I've instrumented the state of a number of relevant registers in the hard fault handler, using code found on the internet. But I'm having trouble understanding what the state of the registers implies. Any help by folks here who really understand this part of the architecture would be appreciate, particularly the fact that the hard fault seems to triggered by a debug event. It makes little sense to us, as does the fact that the PC is seemingly set to the beginning of da

Is External loader programming possible using SPI through STM32CubeIDE(It should program internal and external memory at the same time)?I am able to generate .stldr and program the external serial flash(Connected via SPI) using this file(.stldr) in STM32CubeProgrammer.Is it possible to do the same using STM32CubeIDE? As this will program internal and external memory at the same time? I have tried this after selecting the .stldr file in debug_configuration of STM32CubeIDE , but it's not working.Please confirm the same.Thanks in Advance

Hello, I am facing a weird issue with accessing STM ROM bootloader for flashing.Hardware Used: STM32H745-DISCOIDE: KeilI have created a simple bootloader which jumps to ROM Bootloader at startup.startup_stm32h745xx.s: ; Reset handler Reset_Handler PROC EXPORT Reset_Handler [WEAK] ;Then check if we need to jump to ST Boot loader LDR R1, =0xE000ED00 ; SCB LDR R0, =0x1FF09800 ; ROM BASE STR R0, [R1, #8] ; VTOR LDR SP,[R0, #0] ; ROM Stack Pointer LDR R0,[R0, #4] ; ROM Program Counter BX R0 When I power cycle and try to connect via STM32 CubeProgrammer, I get below error:  But when I press Reset button on STM32H745-DISCO, then connection is succesful without any issue I am wondering what's the difference between pressing reset button and power cycle.Any advice on how I can fix the issue.

Hi,How to use STM32G071 watchdog timer with STM32Cube IDE ?--karan

Hello everyone,I have the following failure. I installed the STM32 Cube Programmer on Windows 10After installation I tried to start the programm but the programm will not start and i get the failure."CubeProgrammer_API or one of its depndencies missing. Please try reinstalling the program or check your java architecture."But on my windows 10 system is "Microsoft OpenJDK 11.0.16.101 in 64 Bit" already installed.Does anyone have a tip or an idea what to do to make the program work?

I've got a strange problem. My custom-built board has SWD problems after cold reset with my code. I don't think that my code is directly responsible for altering the SWD interface.I'm using an in-house SWD probe that has a long history. JTAG/SWD are my areas of professional expertise. When SWD fails, I mean that SWD initialization fails at the lowest level - the SWD interface doesn't respond to the initial SWD probes.Heres what I know:SWD works when I assert BOOT0 and use the in-rom boot loader.SWD drops out when I reboot into my code.If I add a software breakpoint to my code after all SOC hardware init, SWD keeps working, and works after I remove the breakpoint.If I cold reset the board SWD fails.I've verified that the code readout protections are not turned on when the board is in an unreachable state.My best guess is that something is going wrong with the DAPCLK. My code is already using SRAM4, so I know that D3 is powered up.My board is modeled on the STM32H725 dev board, although

I'm writing a C# version of the USB_Example program. You can set the loader path using the setLoadersPath call, but the path of the Data_Base directory seems to be fixed to "/../Data_Base/<whatever you are trying to connect to>.html. Is there any way of changing this path too? I'm using the latest 2.11 API

I've noticed that if the option byte for the CM7 boot address is set to 0x1FF0 (boot into bootloader), the Cube Programmer cannot erase the flash memory. If I change that option byte to 0x0800, the flash memory erases.I can erase and program the flash memory fine using ST-LINK independent of the CM7 boot address setting. But I want to be able to erase flash memory via DFU with the bootloader with the boot address set to 0x1FF0 for the CM7 core.Is there something that limits the bootloader in DFU mode from erasing flash memory if the CM7 boot address is set to 0x1FF0?I've verified that no write protection is set and the memory is not protected.

Hello,I have the following problem with STM32F429ZI: When applying RDP level 1 protection, the board gets stuck if I press the reset button. More precisely, I can see from STM32CubeProgrammer that SPRMOD and BFB2 bits have risen and that the value of RDP becomes FF (not “55�? as I would expect for RDP level 1). The only way to make the board work again is to apply RDP level 0 manually using STM32CubeProgrammer.To reproduce the error, download the “UART_Printf�? example for the STM32F429ZI-Nucleo (from Github STMicroelectronics/STM32CubeF4, unfortunately, I can not add the links) and modify main.c like this:void TurnOnRDP() { FLASH_OBProgramInitTypeDef obConfig;   HAL_FLASHEx_OBGetConfig(&obConfig);   if (obConfig.RDPLevel == OB_RDP_LEVEL_0) { printf("\n\r Applying RDP-1"); // this is first time we run mcu after flashing firmware obConfig.RDPLevel = OB_RDP_LEVEL_1; HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); HAL_FLASHEx_OBProgram(&obConfig); HAL_FLAS

Hi Community, In my project I have successfully added the image buffer in external flash memory and able to read/write to the same. But now I am facing the problem when I added the .obj or .bin videos file in the external flash memory with the help of linker script and STM32CubeProgrammer, but that amount of .obj or .bin file is not appearing in the external memory.Can You guide me how to add the .obj or .bin video files in External Flash Memory? Is this possible by project code itself or need the edit in the linker script. if yes then pls give me some examples or demo?/Mit

Just installed the new version 2.11.0. Never used any version of CubeProgrammer before. I am using it on Windows 10 with Java 18.0.1.1.2022-04-22. When I start it, just the start-dialog appears and disappears after some seconds. In varioius posts I have seen that this happens since years. Hints to re-install Java or use another version didn't seem to work. As the programmer is distributed with an jre, I tried to set path to its bin-directory and JAVA_HOME to the jre path, but this didn't change anything and calling java.exe from the programmer-directory just leads to a java-error message. Any hint how to get it running?

I am getting CUBEPROGRAMMER_ERROR_NOT_SUPPORTED (-5) when I try to connect to a device using connectDfuBootloader from STM32CubeProgrammer API v2.7.0. I am logging all the messages I am seeing and I have attached the log to this question. Does anyone know what I'm doing wrong or not doing. The C++ example seems to work fine. I am trying to write a C# application.

Dear allIf we clear the IWDG option (enable watchdog by hardware at bootup), we cannot undo this.In that case we have to use the old STM32 ST-LINK Utility tool.STM32CubeProgrammer version: v2.11.0µC: STM32G474RBT3The problem seems to be PC dependent!Thanks in advance,Franz

I am calling setVerbosityLevel of the API with CUBEPROGRAMMER_VER_LEVEL_NONE (0) in the C++ USB Example project supplied but the DLL routines (like connectDfuBootloader) are still outputting messages. Still there any way to stop these messages?

Using STM32CubeProgrammer V2.11.0 on Windows 10I have issues erasing sectors past 127 on the STM32L496RET6 MCU.Erasing sectors 0-127 appears to work okay.Erasing sectors 128-255 does not show an error, however when I re-connect the programmer to the MCU the data is still shown in flash.My option bytes are set as:WRP1A_STRT = 0x10WRP1A_END = 0x17WRP1B_STRT = 0xffWRP1B_END = 0x0

Hi all -I'm modifying some legacy code written for a WICED device that contains an STM32F2xx. The original programmer had a passage that reduces down to:#define OB_RDP_Level_0 ((uint8_t)0xAA) #define OB_RDP_Level_1 ((uint8_t)0x55)   FLASH_OB_Unlock(); FLASH_OB_RDPConfig( OB_RDP_Level_1 ); FLASH_OB_Launch(); FLASH_OB_Lock(); NVIC_SystemReset( );I have no idea where he got the value "55" but the upshot is I can't reset my OBs. When I try, I get this output from the programmer software: 15:15:33 : Option byte command : -ob RDP=170 15:15:33 : PROGRAMMING OPTION BYTES AREA ... 15:15:33 : Bank : 0x00 15:15:33 : Address : 0x40023c14 15:15:33 : Size : 12 Bytes 15:15:52 : UPLOADING OPTION BYTES DATA ... 15:15:52 : Bank : 0x00 15:15:52 : Address : 0x40023c14 15:15:52 : Size : 12 Bytes 15:15:52 : Error: Uploading Option Bytes bank: 0 failed 15:15:52 : Error: Reloading Option Bytes Data failed 15:15:52 : Time elapsed during option Bytes configuration: 00:00:18.761 15:15:52 : Erro
