Here is an external loader a code that helps the STM32CubeProgrammer to download the data "images.bin" to external memory like Winbond W25Q16. For all STM-Boards you will get an external loader e.g. in sub folder "\bin\ExternalLoader" of STM32CubeProgrammer If you have a no-name board, you have to make your own external loader for downloading data to external memory. I have a no-name board with controller STM32F407 and an external memory from Winbond W25Q16. If you have the same no-name board you can use the external loader 1W25Q16_STM32F4xx.stldr in this repository. Copy the file in sub folder "\bin\ExternalLoader" of STM32CubeProgrammer and you can choose them. I added in the repository only the relevant folders. In STM32CubeIDE it looks like this

An explanation to build an other external loader find you in the link below.
For automatic renaming the elf-file you can use the command in cmd-stldr.txt.
