installing ubuntu on beaglebone black

Porting UBUNTU on the BeagleBoard:

Following are the steps to port another operating system, Ubuntu, on the
BeagleBoard Xm.
Steps:

 Make your home directory to store all the files for the Ubuntu operating system.
(root files)
 Plug in your micro SD card onto your host laptop system.
 Now we need to get the armel:

wget http://ynezz.ibawizard.net/beagleboard/natty/ubuntu-11.04-r1-minimalarmel.tar.xzmd5sum ubuntu-11.04-r1-minimal-armel.tar.xztar –xvf ubuntu-11.04-r1-minimal-armel.tar.xz
 
 Instead of the above commands, you can use the files in my folder ‘Ubuntumake’.
 Now, enter the following:

cd ubuntu-11.04-r1-minimal-armel.tar.xzsudo ./setup_sdcard.sh --mmc /dev/sdb --uboot beagle_bx --rootfstype ext3
 This process includes formatting your SD card, transferring boot files into the
boot partition and the rootfilesystem onto the other partition of the memory
card.
 When it is done, remove the SD card, and plug it back after 2-3 seconds.
 You will see two partitions, as listed below.
 Remove the SD card from the card holder and plug it in the Beagleboard and
switch on the power.
 Connect the Serial (BeagleBoardxM) to USB(Host PC) converter and configure the
minicom connection.
 Start minicom on your host machine in configuration mode. As root:
#minicom -o -s -w
· A menu of configuration should appear. Use the Down-arrow key to scroll
down and select the Serial port setup option, and press Enter.
· Verify that the listed serial port is the same one that is connected to the
target board. If it is not, press A, and enter the correct device. This is
/dev/ttyUSB0 on most Linux distributions.
· Set the Bps/Par/Bits option by pressing the letter E and using the next
menu toset the appropriate values. You press the key that corresponds to
the value 115200, and then press Enter.
· Set Hardware flow control to No using the F key.
· Set Software flow control to No using the G key.
· Press Enter to return to the main configuration menu, and then press Esc
to exit this menu.
 Reset the board, and wait for a moment. If you do not see output from the
board, press Enter several times until you see the prompt. If you do not see any
output from the board, and have verified that the serial terminal connection is
setup correctly, contact your board vendor.
 You will see something like this when the kernel boots.
Once, it has booted, it will ask for a login, and a password.
The login is ‘ubuntu’, and the password is ‘temppwd’.
 It is necessary that you update your kernel using the following command.
 Use an Ethernet LAN cable to connect the Beagle board to a LAN port.
 To get the Ethernet working, enter the following command.
sudo dhclient eth0
 You can check your assigned ip-address using ifconfig –a
 Now you can run the following commands.
sudo apt-get updatesudo apt-get install build-essentialapt-get install gccsudo apt-get install openssh-serversudo apt-get install openssh-client
Options for compiling:
1.On the Host:
- You can compile your code on your host system (laptop) by:
gcc sample.c
Transfer the a.out file to the target. (Using scp as explained later)
On the target:
chmod 777 a.out./a.out -> to execute it.
2.On the target:
- You can compile your code on the target using:
gcc sample.c (OR)
arm-angstrom-linux-gnueabi-gcc sample.c./a.out -> to execute it.
3.Code Sourcery:

Transferring files using SCP:
Firstly, configure ip addresses of both host and target:
ifconfig eth0 192.168.1.XX
You can check it by running
ifconfig –a and ping on both sides.
To transfer a file from a host to a target (for example), run the following
command on the host:
scp a.out ubuntu@192.168.1.14:/home/ubuntu
