I can use STM32CubeProgrammer to read and write code into external memory via ST-Link. However it fails to access the external memory via the bootloader interface(e.g USB). Does any one know how to fix the issue?Thanks in advance

Hello every one,I have being used STM32CubeIDE to develop a project, and then using STM32Programmer to program the code into internal flash. with more features added, specially more images added, the internal memory is not enough to store the code, s...

Thanks Tesla. However, I still don't understand something such as how to configure USBD_DFU_MEDIA Interface, the MCU I am using is STM32L4xx. Does any one have an example for the DFU uploading external memory?

Hi Tesla,you mean for programming code into external memory by STM32CubeProgrammer, I have to implement my own DFU? I can program code into internal flash via USB interface. does STM32CubeProgrammer only provide the DFU loader for internal memory?

Hi Tesla,Thanks a lot. It works. using arm-none-eabi-objcopy.exe -O binary --only-section=ExtFlashSection "${BuildArtifactFileBaseName}.elf" ExtFlash.bin can generate ExtFlashSection code from the elf file.

Hi Tesla,thank you for your information. can you give the link where to discuss the similar topics?you mean I can use STM32CubeProgrammer to program the one file, and the Programmer will automatically program the corresponding code into corresponding...

How to program a executable file into internal and external memory

Hello, I am using STM32L4xx MCU, the UID is 96bits, I have got the 96-bit. Unfortunately I have only 64 bits space for serial number. so I have to convert the 96-bit to 64-bit, and the converted 64-bit must be unique. does anyone have the solution?
