Thanks! It seems work. But what difference between direct jump to 0x700000 and do it through RSCTRL register?

Generally speaking, using the reset control register is the more robust methodology.

I realize it is now 6 years later, but that document no longer seems to exist. Has it been subsumed into some other document? Where can I find it? I'd like to understand how the RSTYPE register works.
Thanks,
Mike
