Zaurus SL-C700 Kernel Compilation

How to compile kernel on Gentoo Linux:

download OZ gcc-toolchain : http://openzaurus.org/official/toolchain/cross-2.95.3.tar.bz2

uncompress to /usr/local/arm/

export PATH=/usr/local/arm/2.95.3/bin:$PATH

Kernel stuff:
download kernel sources :
http://more.sbc.co.jp/sl_j/source/b500/20030124/linux-c700-b500-20021214-rom1_00.tar.bz2

install bitkeeper (emerge bitkeeper)

1. bk clone http://openzaurus.bkbits.net/buildroot buildroot-oz
2. cd buildroot-oz
3. bk -r co -q
4. cp /arch/def-configs/poodle-j

Patch kernel sources:
cd your_kernel_tree; cat /path/to/the/buildroot/packages/kernel-c700/compile.patch | patch -p1

5. make menuconfig to disable Xscale Cache errata
6. Go into build settings, select your linux distribution. Save, and exit.
7. make
8. make dep
9. make clean zImage

Once the zImage created, you just have to replace the zImage.bin provided with your latest official Sharp rom update and reflash the whole thing.
