==============================

drivers

  The low level device drivers for C33 peripherals
  and external devices such as the CTP

fatfs

  The tiny FAT file system code from http://elm-chan.org/ used to
  access the FAT32 files on th micro SD Card. This version does not
  use long file names, only the standard 8.3 is supported.

flash

  This creates flash.elf which is a program to run on the WikiReader
  device to copy the contents of a 64kB file called flash.rom to the
  internal SPI FLASH ROM chip.

forth

  An almost complete ANSI Forth implementation along with some scripts
  in the programs sub-directory used for device testing. The
  forth.elf program can be booted by the mbr program and run forth
  programs (*.4th) directly from the micro SD card.

  There is a simple menu program that displays certain files (*.4mu)
  that can be run via CTP/LCD without requiring access to the serial
  console.

include

  Some header files containing C33 CPU register definitions and
  in-line functions for hardware initialisation.

  There is an important configuration file here: config.h create this
  from config.h-default and uncomment the "#define BOARD_SAMO_V1 1" to
  enable compilation for production hardware.

lzma

  Decompression library used by the wiki-app program.

mahatma

  Startup code for the wiki-app program, this produces the statically
  linked WikiReader application that is installed on the SD card as
  kernel.elf This only contains some interface code between the
  drivers and the higher level application (in the wiki-app directory
  one level up).

mbr

  This is the code that goes into the on-board FLASH ROM chip. It
  consists of a boot block (mbr) of 512 bytes that is loaded by the
  CPU into internal RAM during the power-on reset sequence.

  There are also a set of applications that are loaded into the FLASH
  mostly for production testing or hardware diagnostics via the
  console port.

  After mbr has been loaded it loads the menu application which, if no
  character is received on the console will load the kernel.elf after a
  short delay. Once control is transfered to the application the
  FLASH is not used until the next power cycle. Holding search key
  down during boot will load the forth.elf program, which allows some
  test programs to run.

  The console (19200 8N1) can be used to run some tests of SDRAM and
  keys.

  The image file flash.rom is here.

mini-libc

  These are a minimum set of stdio/stdlib routines used by the wiki-app

misc-files

  Some additional files that are copied to the micro SD card

Mk

  Files include by various Makefiles for standard rules and definitions

scripts

  Some scripts used during early testing
