Updating Ben NanoNote software
The NanoNote in its initial state is "empty" and needs to be flashed first. Luckily, this can be done relatively easily via USB (no JTAG or serial required).

install
First, download and install usbboot from the xburst-tools package: go here to download the package you need.
deb package:
$ dpkg -i xburst-tools_0.0+201002-1_i386.deb
bin tarball:
$ sudo tar jxvf xburst-tools_0.0+201002-1_i386.bin.tar.bz2 -C /

$ sudo rm -f /usr/local/bin/usbboot $ sudo rm -f /usr/local/man/man1/usbboot.1.gz $ sudo rm -rf /usr/local/etc/xburst-tools/ $ sudo rm -rf /usr/local/share/xburst-tools/
How to reflash
Get the reflash_ben.sh script and make it executable (you only need to do this once per system you want to reflash from, unless the reflash script changes) via the following commands:
$ wget http://downloads.qi-hardware.com/software/images/Ben_NanoNote_2GB_NAND/reflash_ben.sh $ chmod +x reflash_ben.sh
|
DO NOT USE A USB HUB. Make sure your NanoNote is directly connected to a Linux PC |
Boot your NanoNote into USB BOOT mode. As soon as lsusb (on your Linux PC) lists a new device, run reflash_ben.sh. This will download some pre-built images and (re)flash the NanoNote.
$ sudo ./reflash_ben.sh
Afterwards, reboot your NanoNote. First, you will see
- preinit - Press CTRL-C for failsafe
After a while, you will see Please press Enter to activate this console. on the console of your NanoNote.
Notes
- After reflashing the device, the first boot will take about 3-5 minutes (a script erases the NAND flash that is not used by the rootfs). Subsequent boots will be faster.
- The usual boot time is around 10 seconds.
- You can erase the rootfs partition with the command:
$ sudo usbboot -c "boot;nerase 16 1008 0 0"
- You can reflash just the rootfs partition with ... please fill this in, someone.
- Remember, the block size in the flash is 4kiB (4096 bytes).
