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.
NookDevs Nook Color Portal, good source of information
Novomok have beaten the community to the punch with MeeGo on the Nook Color!
Hardware believed to be present, but not active
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.
A patch by Oleg Drokin that adds board file, serial console, gpio keys, MMC/SDCard and USB (peripheral) support has been accepted upstream. So Nook Color support is now available in the linux-omap-2.6 git tree and will be eventually pushed to linux-2.6.
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.)
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.
The card I created is based off of one of the Clockwork Recovery images, in particular a 4GB image reworked to boot MeeGo from the SD Card.
The simplest format is as follows, created using parted:
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
Empty, probably not necessary
MeeGo root filesystem
The Nook Devs instructions will suffice for building a proper uImage. I will post the source of my u-Boot shortly.
Tech docs @ NookDevs. There is apparently a way to get RS232 out over the USB port, if you disable USB and enable the output in u-Boot.
If you happen to come across any source code, patches, or the like (that are open source) then please let me (wmarone) know so they can be consolidated in a repository on Gitorious. Passing binaries and source code around using mediafire or other download sites just isn't right.
