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 -p1 -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 gzip -9 -f arch/mips/boot/vmlinux.bin OWRT 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 Jlime mkimage -A mips -O linux -T kernel -a 0x80010000 \ -C gzip -e 0x`mipsel-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'` # should be NN=192.168.254.101 for OpenWRT, # NN=192.168.1.202 for Jlime - 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' - press ^C to return to the shell 4. Set up the user space on the Ben - connect to the Ben ssh $NN - run the following commands: OWRT opkg install ip OWRT opkg install ldconfig mkdir -p /usr/local/var/run exit 5.
