I am new for ubuntu core, and I am trying to understand Ubuntu core.
I have confusion about gadget. base my understanding, gadget is snap file, and it can load and start kernel snap.
but if gadget is the first stage during booting, Who is responsible for extract gadget and get original uboot for starting? Because CPU can work with original uboot ( build from uboot source code by make ), but can’t work with gadget (not original uboot, it is a snap file builted by snapcraft).
