### 1 - Download files in [http://www.uclinux.org/] (http://www.uclinux.org/)
m68k-elf-tools-20030314.sh
uClinux-dist-20041215.tar.bz2
[m68k-elf-tools-20030314.sh](http://www.uclinux.org/pub/uClinux/m68k-elf-tools/m68k-elf-tools-20030314.sh)
[uClinux-dist-20041215.tar.bz2](http://www.uclinux.org/pub/uClinux/dist/uClinux-dist-20041215.tar.bz2)
### 2 - Preparing the uClinux
$ mkdir /comum
$ chmod 777 /comum
$ mkdir /comum/uclinux
### 3 - Installation
#./m68k-elf-tools-20030314.sh
### 4 - Uncompress
$ /comum/uclinux
$ tar -jxvf uClinux-dist-20041215.tar.bz2
### 5 - Compile uClinux
$ cd /comum/uclinux/uClinux
$ make menuconfig
Kernel Configuration
--------------------
There was an error of no Library
Solving the problem
kurumin@ltr03:/comum/uclinux/uClinux-dist$ apt-get install libncurses5-dev
Continuing
$ make dep
$ make
### 6 - Install TFTPD
The TFTP server used for the server image file uClinux
# apt-get install tftpd
# mkdir /tftpboot
# chmod 777 tftpboot
### 7 - Edit the file /etc/inetd.conf
To that TFTP is running as a service, every time the computer starts
$ mcedit /etc/inetd.conf
`tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftpboot`
### 8 - Restart network services
$ /etc/init.d/inetd restart
### 9 - Verify that the TFTP service is already running
$ netstat -tuanp
`udp 0 0 0.0.0.0:69 0.0.0.0:* 4477/inetd`
### 10 - Install MINICOM
Used to perform serial communication with the board
# apt-get install minicom
#### Configuring the Serial Port
# minicom -s mod5272
Configuration
Baudrate = 9600
Serial port = /dev/ttyS0
Hardware Flow Control = No
Software Flow Control = No
#### Save Configuration as mod5272
`Exit from Minicom`
### 11 - Recognizing the plate MOD5272 the TFTP server
It is recommended crossover cable connection to speed up the detection process
# arp -s 10.2.4.123 00:03:F4:01:1E:F0
### 12 - Running MINICOM
Reset development board if necessary
$ minicom -o mod5272
Result
Netburner MOD-5272 (5272) Monitor V1.00 Sep 26 2003 13:57:32

### 13 - Finish And Run
copy image to the /tftpboot
cp images/image.s19 /tftpboot/IMAGE.S19
minicom -o mod5272
Reboot the board with RESET button
Loads the image into RAM
ndl image.s19
