BOOTLOADER: IS POSSIBLE BY HARDWARE INVOKER ?

Marco Fontanesi

Hi,

I need an information:

is it possible to lanch / invoke the ROM USB bootloader by an external pin ?

Because if the M4 is already programmed  and  there is a program failure or a SW bug

is possible that the SW bootloader call don't start.

To improve the ease of product maintenance, the HW invoker may be an option !

thks for answers.

    Hi Marco,

    It is possible.  Please review the information in the data sheet regarding the BOOTCFG register in the internal memory chapter as well as the Boot Loader overview in the ROM section of the internal memory chapter.

    Regards,

    Sue
