# n900
a [9front][1] kernel port to the [nokia n900][2].
[1]: http://9front.org
[2]: https://en.wikipedia.org/wiki/Nokia_N900
## installation
you will need:
- an up to date u-boot on your n900 compiled with support for plan 9 kernels.
the u-boot package in the [maemo.org][3] repositories is unfortunately insufficient.
this is left to the reader.
- an up to date 9front system.
building the kernel requires your system to have the arm libraries
and commands built, so start by installing those:
cd /sys/src/
objtype=arm mk clean
objtype=arm mk install
then, clone this repo to your 9front kernel source, as `/sys/src/9/n900`,
and install it with:
cd /sys/src/9/n900
mk clean
mk install
copy the compiled kernel to a fat formatted micro sd card
and setup the boot scripts:
cp /arm/9n900.u /n/dos/9n900.u
aux/txt2uimage -o /n/dos/boot.scr <<EOF
mw 0x80010000 0x0 0x10000
${mmctype}load ${mmcnum}:${mmcpart} 0x80010000 plan9.ini
${mmctype}load ${mmcnum}:${mmcpart} 0x80020000 9n900.u
EOF
now eject the sd card and put it in your n900, boot the system
with the keyboard open, and select external sd card at the [u-boot][4]
menu.
if all goes well, you see the bootargs[] prompt shortly.
no refunds.
