Getting Started
Following the list of articles presented here, in order, will provide a good foundation for building custom embedded applications.
Background Information About EMAC Products
Getting To Know Linux
Getting A Linux Development System Up And Running
The LDC - Linux Development Computer
A popular option to getting started quickly is to use the EMAC Linux Development Computer (LDC). There are two variants on this option, as follows:
- The Hardware LDC: This is a desktop computer with EMAC's customized Linux distribution preinstalled with the full EMAC SDK installed and ready to run. This is the most painless method of getting started, especially for those new to Linux and/or developing software under Linux. This is the most preferable system to use for development.
- The LDC Virtual Machine: This is a virtual machine image which can be used in a virtual machine manager, such as VMWare[1] and VirtualBox. This, like the Hardware LDC, has EMAC's customized Linux distribution preinstalled with the full EMAC SDK installed and ready to run. This option works well, but may require additional set up and configuration of the host operating system.
If this is the method chosen, the system should be already configured for development. Skip to the Getting Familiar with Eclipse section.
Customer Installed EMAC SDK Packages On Customer's Existing Linux Computer
EMAC provides SDK packages which can be installed by customers on their own Linux machines. This is the most difficult method of getting started, but is often preferred by customers who are already highly skilled with Linux.
Should this method be chosen, start with the EMAC OE SDK Introduction..
Getting Started With Software Development For EMAC Machines
Getting Familiar with Eclipse
These articles will help in getting started with Eclipse. If some other editor or IDE is used for development work, this step may be skipped. Working with a different IDE is beyond the scope of the EMAC documentation and will be unsupported. Using the shell based build system will, however, still work as documented.
- First Time Starting Eclipse
- Using the Eclipse Terminal View
- Remote System Explorer
- Execute Remote Applications
Compiling and Running Some Software
- Import Example Projects
- New Project
- Debugging With gdbserver
- Building Existing Software
- Using the EMAC OE SDK Examples Projects
- Create New EMAC OE SDK Projects
- Debug Remote Applications
Working With Bootloaders and OS images
Bootloaders provide the magic glue between the hardware (or the BIOS, on PC compatible systems) and the operating system. The bootloader is the piece of software which points the processor at the operating system image and kicks off the booting process. The bootloader can also be used to load new firmware onto machines, and perform some other tasks. This section provides instructions for loading new firmware images and customizing the boot process.
- U-Boot Bootloader
- Archiving JFFS2 Images from Flash
- Mounting JFFS2 Images on a Linux PC
- Creating JFFS2 Images
- Booting over NFS
- Loading Images with U-Boot
- Boot Process Customization
- Loading the Rootfilesystem and Kernel Onto a CF Card
Old Bootloader
If you have a machine which uses the older RedBoot bootloader, see the article below.
Customizing Linux Kernels and Filesystem Images
This section provides documentation on advanced tasks with embedded Linux; namely, custom Linux OS kernel image building and firmware image customization.
- Building the Linux Kernel
- Custom Linux Kernel Development
- Building and Customizing EMAC OE
- Linux Boot Process Customization
Programming EMAC OE Machines
This section provides some articles for specific to EMAC embedded machines.
Getting Support
Quick Reference
EMAC provides a quick reference guide as a "cheatsheet" to assist with the initial learning curve.
