Is it possible to used the nor flash s29gl512s as external loader? I use stm32f429ig.

You should be able to write an External Loader for whatever devices you choose for your board.

If you can access the memory device from BSP code you have for it, you can use that in a loader.

Thank for answer. I need a file with format .stldr for stmcubeIDE, correct? I can already write, read and erase the flash memory in my code, but how do I create this file for the external loader?
