The Nook Color is an OMAP3621 based 7" tablet produced by Barnes and Noble as an lcd-based e-Reader. At the same time, it serves as quite a handy target for MeeGo due to the similar SoC.

Kernel Sources

B&N have posted the sources for their kernel, bootloader, and xloader, on their legal page, look for Attachments 1 and 2. Attachment 1 is the older 2.6.29 kernel, while Attachment 2 is the newer 2.6.32 kernel.

A project on Gitorious hosting these kernel sources (but not yet u-boot or xloader) is available: https://gitorious.org/meego-nook

Currently there is an official 2.6.32 kernel, along with a community attempted port to 2.6.35, as well as my port of those patches forward to 2.6.38, in an attempt to meet the MeeGo baseline of 2.6.37.

Status

At this point 2.6.38 with drivers and board support files ported forward compiles silently, but does not activate the screen thus giving no useful output. With 2.6.32 and 2.6.29 it is possible to boot up to the login prompt (Xorg must be disabled, or the device will not give any indication of having booted.)

Getting Started

The Nook Color has a particularly well done boot sequence, in that it will default to boot from the SD card slot if plugged into a PC and powered on with a bootable card inserted.

Creating a Bootable Card

The card I created is based off of one of the Clockwork Recovery images, in particular a 4GB image reworked to allow for the 4GB -hardfp builds.

The simplest format is as follows, created using parted:

<code> Number Start End Size Type File system Flags 

1      32.3kB  74.0MB  74.0MB  primary  fat16        boot, lba
2      74.4MB  331MB   257MB   primary  ext2
3      331MB   4428MB  4097MB  primary  ext2
