I've ported Android on to NetWalker, sort of. Required patch files can be downloaded from my github.
This port is still very preliminary and unstable. Current status is just a proof of concept.
NetWalker has a good boot loader that allows us boot from SD card. You can create your own roof file system by following steps.
1) Download os.tar.bz2 and zImage from http://mit.sharp.co.jp/
2) Unzip os.tar.bz2 to SD card formatted as ext2
3) Copy zImage to boot/ directory on SD card
4) Edit boot.conf in boot/ directory
- add console=tty1
- remove quiet
5) Power off
6) While pressing [Left] and [Right], press [Power]
7) Keep pressing [Left] and [Right] until kernel boot message printed.
Now you have a root console. Kernel can be replaced by just changing /boot/zImage. Kernel command options are configurable by /boot/boot.conf. What a heaven.
To boot Android on NetWalker, follow the instructions in README and build kernel and Android system. Then copy zImage to boot/ and Android system to SD card. Now the time to do a familiar chroot to Android system directory.
Cheers,
