How to build a NN kernel for Jlime
==================================

- Download and install the jlime toolchain
- Download the .config kernel file from:
  http://jlime.com/downloads/releases/muffinman/kernels/

# git clone http://projects.qi-hardware.com/index.php/p/qi-kernel/source/tree/master/
git clone git://projects.qi-hardware.com/qi-kernel.git
git checkout -b jlime remotes/origin/jz-2.6.34

# Copy the kernel config file you downloaded to .config. For example:
cp config-nn-2.6.34.txt .config

# Set the PATH as $PATH:/your/toolchain/bin/
export PATH=$PATH:/usr/local/jlime/mipsel-toolchain/usr/bin

make ARCH=mips CROSS_COMPILE=mipsel-linux- clean
# make ARCH=mips CROSS_COMPILE=mipsel-linux- menuconfig
make ARCH=mips CROSS_COMPILE=mipsel-linux- vmlinux.bin

# Get the set entry point for mkimage command (-e)
echo 0x$(mipsel-linux-nm vmlinux 2>/dev/null | grep " kernel_entry" | cut -f1 -d ' ')

cd arch/mips/boot
rm vmlinux.bin.gz uImage
gzip -9 vmlinux.bin

# You get the value for -e with the echo command above
mkimage -A mips -O linux -T kernel -C gzip -a 0x80010000 -e 0x80014240 -n 'MIPS' -d vmlinux.bin.gz uImage

# cp uImage to FAT partition, or under /boot on MicroSD
