1. Obtain u-boot's mkimage
wget ftp://ftp.denx.de/pub/u-boot/u-boot-2009.11.tar.bz2
tar xfj u-boot-2009.11.tar.bz2
cd u-boot-2009.11
touch include/config.{h,mk}
make SUBDIRS=tools BIN_FILES-y=mkimage tools
cp tools/mkimage /usr/local/bin
cd ..
2. Build the kernel
git clone git://projects.qi-hardware.com/qi-kernel.git
cd qi-kernel
git checkout ben-wpan
cp ../ben-wpan-config-2.6.38 .config
patch -p0 -s <../openwrt-preinit-hack.patch
OWRT make ARCH=mips CROSS_COMPILE=mipsel-openwrt-linux- vmlinux.bin
Jlime make ARCH=mips CROSS_COMPILE=mipsel-linux- vmlinux.bin
../u-boot/tools/mkimage -A mips -O linux -T kernel -a 0x80010000 \
-C gzip -e 0x`mipsel-openwrt-linux-nm vmlinux | \
grep " kernel_entry" | cut -f1 -d ' '` \
-n 'Ben NanoNote Linux Kernel' \
-d arch/mips/boot/vmlinux.bin.gz uImage
cd ..
3. Install the kernel
Using usbboot:
- remove battery and USB
- wait 15 seconds
- press the "U" key on the Ben
- insert USB while keeping "U" pressed
- release the "U" key
- on the host, run
usbboot -c "boot;nprog 1024 qi-kernel/uImage 0 0 -n"
- disconnect USB
- wait 15 seconds
- connect USB again
Using nandwrite:
- set up TCP/IP networking with the Ben
- get the Ben's IPv4 address:
NN=`ifconfig usb0 |
sed '/.*inet addr:\([^ ]*\).*/{s//\1/;s/100$/101/;s/200$/202/;p;};d'`
- copy the kernel:
scp qi-kernel/uImage $NN:
- flash the kernel, clean up, and reboot:
ssh $NN 'PATH=$PATH:/usr/sbin;
flash_eraseall /dev/mtd1 && nandwrite -p /dev/mtd1 uImage &&
rm -f uImage && sync && sleep 1 && sync && sleep 1 &&
/sbin/reboot -f'
4. Set up the user space on the Ben
OWRT? opkg install ip
OWRT opkg install ldconfig
OWRT? mkdir -p /usr/local/var/run
5. Build libnl-1 for cross-development and install the run-time library
wget http://www.infradead.org/~tgr/libnl/files/libnl-1.1.tar.gz
tar xfz libnl-1.1.tar.gz
cd libnl-1.1
OWRT gcc=`readlink \`which mipsel-openwrt-linux-gcc\``
OWRT ./configure --prefix=${gcc%/bin/*} --host=mipsel-openwrt-linux
Jlime ???
make
make install
scp lib/libnl.so.1.1 $NN:/usr/lib
ssh $NN /sbin/ldconfig
cd ..
6. Build the user space tools of the linux-zigbee project
wget http://ufpr.dl.sourceforge.net/project/linux-zigbee/linux-zigbee-sources/0.2.2/lowpan-tools-0.2.2.tar.gz
tar xfz lowpan-tools-0.2.2.tar.gz
cd lowpan-tools-0.2.2
OWRT ./configure --host=mipsel-openwrt-linux
JLime ./configure --host=mipsel-linux
make
scp src/iz src/izcoordinator src/izchat $NN:/usr/sbin/
