Dear STM32CubeProgrammer Community, I hope you are all doing well. Over the past months, you may have received an email from me, either through the STM32CubeProgrammer survey or on other topics like CSAT or Raspberry Pi support. First, I would like...
Major change in SigningTool for STM32N6 in STM32CubeProgrammer v2.21.0 This release, we decided to change signing tool behavior to not automatically align the payload to 0x400 with padding bytes, since this is not necessary for other STM32 series. T...
Hi,Since I updated the STM32CubeIDE to v1.8.0 each second flash process fails with Error: Data mismatch found at address. With the STM32CubeIDE v1.6.0 everything works fine.In the project the start address of the flash area is set to 0x08010000 becau...
I am trying to flash a custom PCB having STM32H743IIK6 MCU using SWD interface. I have tried below methods but all are Failing. Flashing using 'STM32CubeProgrammer' using all 'Mode' and 'Reset Mode' options FailedFlashing using STM32CubeIDE tried usi...
The EEPROM erase function doesn't seem to work with STM32CubeProgrammer v2.13.0, but works fine with STM32CubeProgrammer v2.11.0. Although v2.13.0 reports that the erase worked, the content of the EEPROM remains unaltered. Furthermore, something else...
I want to see the RAM content of a Running Device. I suspect it might be got corrupted. Also, I don't want to Reset the device. I think connecting the device using Hot Plug mode in STM32Cube Programmer is the solution for this. But I am not able to c...
Dear allUnder windows 11 the 64 bit setup (2.11) startswith extracting the file and after that I see sometimes the busy signal, but... There are no entries in the windows event logger.I know, that windows 11 isn’t mentioned in the release notes (RN01...
Hello,I renamed my custom external loader and now STM32CubeProgrammer gives an error each time I launch it. The new external loader is loaded without problems but I keep getting this error. Is there a way to clean the list of expected external loader...
Hello Everyone,I'm working on the Mikromedia 7 Capacitive board and I'd like to store my fonts and images in my external Flash Memory, the SST26VF064B. I searched in /bin/ExternalLoader and there is no example for this Flash.So I decided to make my o...
Using ST-link V3.MCU: STM32L031First programming was ok. After disconnecting and reconnect with second device, nothing happen.Using same set of hardware, but changed software to ST-LINK Utility.Result: ok. Automatically programmed the second device.
Has anyone experienced issues trying to run STM32CubeProgrammer on Apple Silicon, and overcome them?I am trying to use it to flash to an STM32F103 micro, but the flashing fails partway through.The issue reproduces using the CLI version of STM32CubePr...
I was trying to modify the option bytes (changing the bit nSWBOOT0) on my STM32G491VC with STLinkV2 (latest firmware).After writing was succesfull, I was no longer able to flash my chip or read the flash content. it tunred out that somehow the read-o...
