---+Agenda for Training course Embedded GNU/Linux Systems Architecture

If you intend to bring a laptop to the training (which is possible) it
should have a GNU/Linux system running on it with at least the
following packages installed:
 
   * gcc GNU C compiler
   * NFS server
   * xinetd and tftp server
   * kermit (usually called ckermit as a package)
   * ethereal the network analyzer
   * ddd the graphical debugger
   * git versioning system
   * stgit stacked git
   * expect script language
   * flex and bison

---++ Day 1:

Introduction, Environment Setup + Host Linux Setup

This is basically the installation of our ELDK (cross toolchain + NFS
root filesystem) but _every_ concept needed to fully understand this
will be presented, i. e.

   * Basic shell concepts needed for ELDK usage
   * Concept of UNIX daemons
      * (TCP/IP knowledge to understand internet servers)
      * The internet superserver
   * NFS and its usage
   * Detailed look at the Linux filesystem hierarchy
   * Introduction to UNIX/Linux startup

---++ Day 2:

   * Setting up the BDI2000

Linux on the target

   * Connecting to the target for the first time in U-Boot
   * The power of U-Boot and its command line
   * Configurations of U-Boot
   * Compiling the Linux kernel
      * Kernel make infrastructure
      * Kernel config options
      * Kernel command line
   * Booting the target into Linux / ELDK rootfs for the first time
   * Using our native tools in the ELDK

---++ Day 3:

   * Native debugging of simple application
   * "Cross-debugging" of applications with gdbserver
   * Using the BDI2000 as a "gdbserver" to debug U-Boot
   * Using the BDI2000 as a "gdbserver" to debug the Linux kernel
   * Overview of Linux architecture and source code structure at a very
    detailed level

---++ Day 4:

   * Introduction to U-Boot Linux bootstrap and Linux startup
   * Revisiting the UNIX file API to see what character drivers have to
     be implemented. (open/close, read/write, lseek, ioctl, mmap)
   * Taking a look at existing drivers to see how this works
   * Discussing a character driver framework implementing all "kernel
     hooks"

---++ Day 5:

   * Debugging a Linux character driver with the BDI2000
   * How to start a new U-Boot port (most problems to solve here will
     be needed for the Linux porting)
   * Glue between U-Boot and Linux
   * Linux parts to adapt when porting to new hardware
