作者: kztop1 时间: 2011-9-6 13:03:45 标题: How to Run Ubuntu 10.04 on your PandaBoard(1)

There are few locations on the Internet very useful in helping us getting the information we need to run Ubuntu on PandaBoard. However, it took me quite a while to read all that and find the correct and exact steps I need to take to have a stable and working Ubuntu system at the end. So, I decided to have this knol specific to PandaBoard to help me and others in doing the same.

Contents

Items you will need:

What Options do we Have?

Using the Pre-Installed OMAP4 Images

To Run the Demo Release follow these steps:

Find and download the correct Ubuntu image Maverick 10.10

Install the image to your SD Flash

Run your new Ubuntu system and enable Ethernet connection

Change the default password to default user "ubuntu"

Add new user and set the password, then add the user to sudo group

Install GUI xfce4 :-) more fun with PandaBoard :-)

Enabling the WiFi and BlueTooth on PandaBoard

Install SSH and Configure it to have a better security to be able to connect to the board later for development

Change you HostName of your PandaBoard

Some References

Items you will need:

Ubuntu Host computer, or any Linux based OS, Preferable Ubuntu
Internet connection
Be familiar with how to install packages on Ubntu
PandaBoard, or any other ARM based board like, BeagleBoard, GumStix Overo, or others you might have to search the differences in hardware and adjust for that

What Options do we Have?

Using the Pre-Installed OMAP4 Images, it is full and stuffed with the full Ubuntu Net-book
Follow the Demo release which is very basic and will be a way to star from the ground up

Using the Pre-Installed OMAP4 Images

I will have to go in more details later, but for now, follow this link it will send you to OMAP Images from Ubuntu.com
then you need to go and get the OMAP4 Addons

To Run the Demo Release follow these steps:Find and download the correct Ubuntu image Maverick 10.10

Go to this link and download the image Ubuntu Maverick
I suggest you go and visit this link and get the latest release
You will need to unpack it
- tar xJf ubuntu-10.10-r7-minimal-armel.tar.xz

Install the image to your SD Flash

CD to the new folder and run the script file
- cd ubuntu-10.10-r7-minimal-armel
- sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot panda
Replace sdX with the correct dev name to your SD card
You might be asked to install some packages first, copy the list of packages and install them then run the script again
This is going to take a few minutes
Once the script is done you are ready to insert the SD card into your PandaBoard

Run your new Ubuntu system and enable Ethernet connection

Once you insert the SD card into the PandaBoard you should be able to power it and see Ubuntu start. First thing we will need to enable the network after you login. Again, the user ID: ubuntu and Password: temppwd
type the following to test available Ethernet Devices
sudo ifconfig -a
This command will show you a list of devices eth0, usb0, or usb1
On my PandaBoard it is usb1
sudo dhclient usb1

Change the default password to default user "ubuntu"

You can always change the default user "ubuntu" password on your PandaBoard
Actually, I strongly recommend that you do that for security so make your own password
If you logged in as "ubuntu" then all you need is to type passwd
- You will get a prompt asking you for original password which is "temppwd"
- Another prompt asking for new password, type your new password
- Another prompt asking you to confirm the password, re-Type your new password
- that is it, make sure you remember the new password or write down somewhere
- I would always recommend to create another user account and make that account part of sudoers for backup, so go a head and read the next topic if you need to create a new user
If you are logged in as a different user that is just fine,
- go a head and type "su ubuntu" this command will set you as if you were logged in as ubuntu
- Type the password as mentioned before "temppwd"
- Now follow the previous steps from 1 to 5 above as if you are logged in as ubuntu user
- when you are done, type "exit" this will make you exit using the user ubuntu

Add new user and set the password, then add the user to sudo group

To add new user we use "adduser" command
Open a terminal, and type sudo adduser user_name
Replace user_name with the new user you are adding
You will be asked to enter new UNIX password for the new user, then verify it
Make sure you choose a strong password and make a note of it
You will be asked few times for more information such as Full Name, Room Number, ... you do not have to enter any values and just press Enter
You will get the question "Is the information correct? [Y/n]" Type y after you verify the information you typed and press Enter
The new user account has been created successfully!
now to get your user to be in the sudoers group follow this link "add user to sudoers"

Install GUI xfce4 :-) more fun with PandaBoard :-)

At some point you will need to run a GUI on your PandaBoard. There are few desktops you can install, but, the one I tested successfully is xfce4 desktop, very nice and runs smooth on the PandaBoard. Here is how to install it:

Make sure you enable the network on your PandaBoard, follow steps mentioned above
Run sudo apt-get update then sudo apt-get upgrade to make sure your system is up-to-date
Run sudo apt-get install xfce4 gdm xubuntu-gdm-theme xubuntu-artwork xserver-xorg-video-omap3 network-manager
when it is done you will be able to restart your system and boot right to the new desktop
