Abstract
The electronic device may include a RAM, a nonvolatile storage device as an MTD, and firmware that may be stored on the nonvolatile storage device. The firmware may include a kernel that is expanded onto the RAM and a root disk image as a root file system. The kernel mounts the root disk image on the nonvolatile storage device as the root file system when a boot mode of the electronic device is a normal boot mode. The kernel, when the boot mode is an update mode for updating the firmware on the nonvolatile storage device, may i) generate a RAM disk as an MTD in an area of the RAM not under management of the kernel, ii) expand the root disk image on the nonvolatile storage device into the RAM disk, and iii) mount the root disk image on the RAM disk as the root file system.
