I remember reading about a phone called the freerunner designed to be
open that got converted to running Android. The methodology, and
insight is made public online, so maybe someone with more Linux
understanding can give these links a look:

1) http://wiki.openmoko.org/wiki/Android

2) http://wiki.openmoko.org/wiki/Android_usage

3) http://code.google.com/p/android-on-freerunner/

Hope the information proves useful, and helps in getting a proper
Android build on the N900.

<< kernel image for the above.

PLEASE BE AWARE THIS IS NOT A TOTALLY USABLE SYSTEM AS A LOT OF THINGS DO NOT WORK
i am releasing it purely as a development tool and to show my current progress.

Current Status:
Android Eclair 2.1R1 based, modified init files to allow dsp controller init
WiFI and bluetooth NOT working currently - wifi module will load but the calibration tool gives me errors < looking for ideas /help on that
modifed status bar toremove network signal icon,
lcd density set to 120 as it is a better size for the screen resolution in my opinion
battery NOT detected/charging as yet (due to major code changes between donut and eclair - also why everythign else has broken )
swap is autoenabled on boot using a seperate sd partition(see below)
disabled the default voldsdcard mounting and reverted to mountd as it seems to work better
sdcard is detected and mounted


quick howto flash below as this is VERY different from the orig nitdroid info

2gb minimum memory card is recommended due to partitioning i have setup

HOW-TO:
1. download above files to a workign folder.
2. load up your favourite disk partitionign tool and partition the sd card as follows

example below is for my 8gb card

Code:

primary partition 1 = 1.43gb win95 lba type (vfat)
pri partition 2 = 1.86gb linux swap 
pri partition 3 = 1.86gb linux (ext3)
pri partition 4 = 2.48gb linux (ext3)

format the above partitions as needed. parts 3 and 4 MUST be ext 3 as kernel does not have ext2 support currently

4. mount partition 3 as the root partition (for me using command mount /dev/sdb3 /mnt )

5. create the data folder (mkdir /mnt/data) and mount partition 4 on it (mount /dev/sdb4 /mnt/data)

6. extract the rootfs to the root and it should place files into the correct folders.

7. unmount both partitions as they are now finished with.

8. if you havent already grab the nokia flasher tool (search the forums for linK)

9. run the command

Code:

./flasher-3.0-static -f -k zImage --enable-rd-mode -R

assuming you put flasher in same folder as zimage.

IMPORTANT: WHEN DEVICE REBOOTS AFTER FLASH PULL THE BATTERY AND PUT IT BACK IN AND BOOT AS THE KERNEL WILL PANIC IF YOU DONT
also the boot does take time as i have kernel set to boot direct to sd card but the mmc driver in linux-omap sucks so i have to delay boot for 5 secs to let the sd get detected. on the n800 the sd card must go in the ext slot and must be no card in the internal one

hopefully thats good enough to understand

any ideas, suggestions etc welcome, especially on how to get the wifi to work.
also kernel and android both have alsa support built in, but i cannot persuade the alsa-dsp module to load so i doubt sound will work (could possibly be persuaded to on the n810 with correct asound.conf as the n810 has direct access to the sound codec unlike 800) - feel freeto look though

system seems to run fairly well and pretty stable for the most part. usually calender storage does crash though on boot.

Well done on your achievements to far! I'm sure many users of N800 and N810 will be very pleased to be able to extend the life of their devices by loading future releases of your Android rom and as an N900 user, I look forward to what is to come for N900.

I believe that your experiences with Android 2.1 on N800/N810 will make the process of porting Android to N900 faster and easier.

Thanks!
