Reboot after switching core or Reboot menu item; Option to return to previously loaded Rom?

[notmayo]

Is it possible to have any of the boards auto-reboot after flashing the core? Or is it possible to perform a reboot from a main menu item? If not, that is understandable. I couldn't see from Sipeed's docs what the buttons on the dock board of the 25k do.

Would it also be possible to have a main menu item to load the previously flashed rom?

It seems there's not a way on the nano and primer. It basically involves driving down the N_Reconfig pin. That reconfigures the FPGA from flash again.
