Booting Ubuntu on Pandaboard EA3

STEP1: Download the Ubuntu image

Use this link to download the pre-installed image of ubuntu 10.10. 

http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/10.10/release/ubuntu-netbook-10.10-preinstalled-netbook-armel+omap4.img.gz

STEP2: Prepare the SD card

Insert the SD card in your PC and unmount it. Then use this command to copy the pre-built image on the card.

COMMAND:

sudo sh -c 'zcat ./ubuntu-netbook-10.10-preinstalled-netbook-armel+omap4.img.gz|dd bs=4M of=/dev/sdb; sync'

STEP3: Download and copy required u-boot and MLO files

For Pandaboard version A2 and later follow these instructions. In our case we had a EA3 version so we followed it.  

1.      Download http://people.canonical.com/~tobin/maverick/panda.tar.bz2 

2.      Untar with "tar -jxf panda.tar.bz2"

3.      Mount the first partition of the imaged SD card

4.      Copy MLO and u-boot.bin (extracted from the tar file) to the mounted partition.

STEP4: Boot from Pandaboard

Now unmounts the SD card and insert it in Pandaboard and give it the power. It shall start booting.

STEP5: Now use the same procedure to install OpenNI and Kinect that we used for BeagleBoard.

Getting to the technicalities

As mentioned in the previous post, we faced certain issues with Ubuntu. We had different concerns for Natty and Maverick. In case of Natty, our main concern was the extra amount of space being taken up by the OS that we had to eventually buy another 8GB SD Card. Thus, as we figured out the main problem with installing Natty is the space constraint.

In case of Maverick, even after strictly following the steps given in the wiki link:https://wiki.ubuntu.com/ARM/OMAPMaverickInstall

We were not able to successfully install it. We were following the installing procedures for BeagleBoard xM ver A3 and later. However, later we discovered that although the procedure for all other versions of BeagleBoard xM after A3 is same, ver C is an expection to it. We figured out that since our BeagleBoard xM was Rev C, we had to adopt different procedure instead of the normal procedure (also mentioned in above link) as an exception.
