    Hi segger,

    I have a question here.

    There is no need to erase internal norflash before programming it, but when JFlash is used to program exernal NorFlash, it seems we need to erase it first before programming.
    Is there a way we can program external NorFlash as the same as programming the internal NorFlash?

    I know you cannot do anything in our own customized flash algo.
    I guess, when we do program internal NorFlash, JFlash.exe give a hand to do erase for us.
    Since we have implemented EraseSector() function in our own flash algo, could JFlash calls EraseSector() automatically as it does for the internal NorFlash?

    Thank you.
