The idea is to update only the part that needs an update. Therefore, each part has its own flash partition:

  • Bootloader "-b-" is the bootloader running a few simple tasks. We do not anticipate frequent changes if any.
  • Linux "-l-" contains the linux kernel. Changes will be rare.
  • Ramdisk "-r-" is the ramdisk consisting of basic but important files to get the Linux system running (e.g. /dev).
  • Application Filesystem (JFFS2) "-j-" is the application named "phone".
