Agenda for Training course Embedded Linux Internals

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:
