uClinux, embedded system for microcontrollers emulated in Skyeye

2011-10-27T06:35:00.000-07:00

Introduction
#########

uClinux is an open source embedded operating system based on 2.6 linux

kernel. uClinux has support for many architectures, and forms the basis

of many products, like network routers, security cameras, DVD or MP3

players, VoIP phone or Gateways, scanners, and card readers.

Today I would like to show how to emulate uClinux in open source

emulator for embedded systems called Skyeye.

Skyeye installation
##############

1. First we need to create a folder arbitrarily named (in this example

it will be project) in a home directory and change our actual location

to it.

mkdir project

cd project

2. In second step we need to dwonload the package of Skyeye from it's

official website www.skyeye.org or other source. You can download it

directly to your project directory or if your download directory is

specified somewhere else you will need to move the Skyeye package to

project directory.

mv ~/Download/skyeye-1.2.6_rcl.tar.bz2

3. Third step, unpacking.

tar jxvf skyeye-1.2.6_rcl.tar.bz2

4. Fourth step, compilation of Skyeye.

cd skyeye-1.2.6_rcl

./configure

make

5. Modification .bashrc file to allow running Skyeye from any directory

in base operating system.

nano .bashrc

PATH=$PATH:$HOME/project/skyeye-1.2.6_rcl

export PATH

source ~/.bashrc

uClinux compilation
################

1. First we need to dwonload the latest uClinux distribution package

from uClinux official website www.uclinux.org. Remember to dwonload it

project directory or move it from your dwonload directory just like with

Skyeye.

cd project

mv ~/Download/uClinux-dist

2. Second step, unpacking.

tar zxvf uClinux-dist

3. Third step, distribution configuration for used processor. This step

show how to customize uClinux depending of used processor.
First change

your location to unpacked distribution directory.

cd uClinux-dist

then use the following command to run configuration menu of uClinux

make menuconifg

Now you can customize your uClinux depending to your microcontroller

system. After that start compilation typing

make

It is possible that you will need to install genromfs.

4. After succesfull compilation you should find two files in images

directory

boot.rom and linux

5. Finally you will need skyeye configuration file which can be

downloaded from www.skyeye.org (probably it will required modification

of this file depending of your system).

running uClinux in skyeye
###################

1. Change location to images directory

cd ~/project/uClinux-dist/images

2. Run uCLinux

skyeye -C ~/myskyeye.conf -e linux

Tip: Hyper V and Cobian Backup Software

2011-10-27T04:11:00.000-07:00

If you want to use Cobian backup software on Hyper V Server you can find a problem with running Cobian interface gui. Standard procedure to run some application on Hyper V is typing name of it's execution file from installation directory in comand line:

cbInterface.exe

In this case, Cobian Backup Software didn't show interface. You need to use -m parameter to solve this problem:

cdInterface.exe -m
