STM32CubeProgrammer (MCUs)

Good morning,We have several equipments working with the STM32L4 MCU. These equipments can be programmed (using STM32CubeProgrammer) from different computers we have at our facilities.In one of this computers, we have a problem when trying to flash the equipments: verification fails and equipment is not correctly flashed as it does not work. If you flash the same equipment using same STM32CubeProgrammer, equipment is correctly flashed. Which is the problem? What do we get such error? How can we solve this? (Please, look at the attached screenshot to see the type of error that is being reported.)Best regards,Dani

After PC boot program works fine for some time but after some time the screen is corrupted. (also seen a completely black or a completely white screen). When clicking the pop-up windows are however OK.

When I load the external NOR flash on STM32429I-EVAL with TouchGFX Designer, STM32 Cube Programer or IAR flash loader, the data is not loaded correctly. There seems to be interleaving 16-bit word of written and not written data. The data written is in ELF format with the external flash data linked to 0x60000000.Testing with custom firmware show that only calling HAL_NOR_Program may produce similar problem, but calling HAL_NOR_GetStatus after each write resolve the problem.Can the default tools be used to program external flash on this board, or some custom software will be needed for flashing this flash chip?

I set External Flash Loader through setExternalLoaderPath(). And I can successfully download content to External Flash by using downloadFile(). But what I erased after using massErase() is the MCU Flash. I can't find the related content of full erasing External Flash in the STM32CubeProgrammer_API.chm manual. So how to full erase External Flash by using CubeProgrammer_API?CubeProgrammer_API version is 2.7.0. (I cannot use the 2.8.0 version, because the 2.8.0 version will cause a fatal error.)

I have a bootloder - this is an application stored in the first sector in flash bank1 which at start is checking if USB is connected and going in flash update mode, otherwise is jumping to a application stored in the next flash sector.The bootloder mode code has DUAL_ BANK enabled and in the .ld file FLASH is defined as 2048k.Cube Programmer in USB connect with this bootloder successfully programs small application that fit in the FLASH_BANK1 but for bigger applications that go over to the second bank the operation fails and the CubeProgrammer : erasing sector 0002 @: 0x08040000 done 14:40:10 : erasing sector 0003 @: 0x08060000 done 14:40:10 : Erasing memory corresponding to segment 1: 14:40:10 : Download in Progress: 14:41:08 : Error: Write failed at address: 0x8100400  14:41:08 : Error: failed to download Segment[1] 14:41:08 : Error: failed to download the FileIt seams is failing at the very start programing the FLASH_BASE_2 0x8100000The bootloder c

I did not set anything though. I did some researches and I try some things :Change the Option Bytes in Target > Option Bytes > Read Out Protection. I don't know if it is relevant of the actual RDP state but when I open this tab, the RDP is on Level 1. When I set it to 0 and click on Apply, after few seconds an error is displayed saying Could not set Option bytes! Please reset the target and retry. and also the flash size of stm32 nucleo is of 512kb but on stmcubeprogrammer it shows 8mb.

Hi, I have STM32F407VET6 with a bootloader which reads microSD card, checks for user application update, flashes if it exist and jumps to use application 0x08004000.All was working fine when my user application was <48kb. I wrote some additional code (which should not impact the start of the application), and now id does not work.Previously debbugging started at "HAL_Init()" like it should when user application was <48kb But now, when user application is >50kb it starts debugging at some kind of wrong address: It does not hit "HAL_Init()" anymore like it should.Why user application size could impact that? Or it could be some kind of different issue?How could I fix this?

Dear,I have a big problem on a STM32G070 and I don't know what I can do to solve it.The system is composed of 2 boards with a STM32G0B1 for the first (master board) and a STM32G070 for the second (slave board).The 2 MCUs are connected by UART and this link is used to update the slave MCU by the first using the STM32 bootloader.The setup was the first MCU (master) programmed with the firmware and the MCU (slave) full erase with the default option byte value.In a first time, I programmed the slave MCU with the STM32 UART bootloader from the master mcu and it was OK. The slave MCU worked well. I rewrite the option byte of the slave MCU by the firmware to be able to used the GPIO BOOT 0 pin as legacy mode.In a second time, I tried to upgrade again the slave MCU using the master and it doesn't worked. I don't removed the power of the boards between this 2 tries.And now, I'm not able to connect to the slave MCU using STM32CubeProgrammer.I have "Error: No STM32 target found!" and "Voltage: 0.

Hello, I have an issue debug issue in my custom board. The debug session works for a while and then stop to working and suddenly after many tries it works again. When the debug session doesn't work, I get:STMicroelectronics ST-LINK GDB server. Version 5.9.1Copyright (c) 2021, STMicroelectronics.

I am using the STL library from X-CUBE-STL. To check the data in flash, I have to calculate CRC in the post build section and upload it to flash. ST provides an example post build command for this. But there is a problem, no data in flash is filled with 0xFF, while in the generated bin file it is filled with 0x00. I figured that I need to add "--gap-fill 0xFF" for this. After adding this command, the bin file was filled with 0xFF as expected, but the CRC value Cube Programmer calculated is still the same. That is, the data being 0x00 or 0xFF did not change to the CRC value generated by Cube Programmer. Could this be a process priority issue in the post build part? Or is there a problem with the cube programmer?Post build given by ST:arm-none-eabi-objcopy -O binary "$ {BuildArtifactFileBaseName} .elf" "$ {BuildArtifactFileBaseName} .bin" && arm-none-eabi-size "$ {BuildArtifactFileName}" && echo "\" STM32_Programmer_CLI.exe \ " -sl \ "$ {CWD} \\ $ {BuildArtifactFileName}

I'm coming across a strange issue, and the documentation for the API isn't really helping much. I've got a small application to load some firmware using the CubeProgrammer_API, and it works perfectly if I point setLoadersPath() to "C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin". However, I'd like to include the FlashLoader files with my project so that STM32CubeProgrammer isn't required to be installed with my software. I copied over the FlashLoader folder and pointed the function to the directory the FlashLoader folder is in, but now when I call connectUsartBootloader(), it fails and returns -5: CUBEPROGRAMMER_ERROR_NOT_SUPPORTED. Any ideas? What exactly am I missing?

I cannot connect to program the STMF7 Discovery. In the attached file a message. What to do? regards Andrzej

Hi Team,I am working on one of the Project where I have to update the new firmware over the UART using System bootloader without STM32CubeProgrammer tool.So, for this I need to implement the C application using STM32CubeProgrammer API's.Therefore, I want to know how to include the CubeProgrammer_API.dll file.Please let me know if any one knows the solution. Any kind of help would be appreciated.

This is how WRP bits are programmed in STLink-Utility CLI:st-link_cli -OB WRP=0xffffffffHowever, CubeProgrammer CLI appears to force me to program WRP bits bit-by-bit; this is not practical. Manual does not deal with details of options programming (which is IMO documentation deficiency, too).Is there a way to write all WRP bits at once in CubeProgrammer CLI?JW

Hi everyone,as the title suggests I would like to program the OTP region of a STM32F4, a STM32F429 to be exact and store a serial number there.My question is, whether this can be achieved by only using the SM32CubeProgrammer v2.8.0 and if I can somehow achieve different serial numbers per device without rebuilding an image over and over again.Furthermore, I'd like to be able to generate ascending serial numbers and write those to OTP memory in Automatic Mode. Is this at all possible?Thanks in advance.

I'm using STM32 Cube API 2.6. I was able to get the C++ API to compile and load code. I need the EXE in my own programming application. I changed the C++ API solution to place the EXE and DLLs in my application solution. I copy the EXE and DLLs to the debugging directory on build in Visual Studio. I'm able to call the EXE and it runs, but it cannot detect my DFU device. I double checked that the DLLs and EXE were copied to the debug directory.In summary, I run the project API and can program my STM32 processor. I run with my program and I cannot detect the DFU. Any suggestions? Thanks

Hi, I have a requirement for upgrading firmware in STM32F401RE using USB DFU in android platform. Is there any tool (similar to stm32 cube programmer)or any other method available for doing the same
