Installing phh's latest ubuntu with nilfs2 rootfs on an sd-card
Make sure you have these things:
- 1x Toshiba AC100
- 1x Linux computer (physical or virtual)
- Either: 1x SD-card (min. 4GB class 6 and up) or 1x USB Mini-B to Standard-A
- An hour or two....or more.
The tideous bit
- Get nilfs-tools for your linux laptop/desktop ( for example sudo apt-get install nilfs-tools )
- Get the latest boot.img, modules, ubuntu tarball from phh and tools from nvidia
- Stick your sd-card to the linux machine and don't let it automount.
- Create a single partition to the sd-card and format it to nilfs2 ( for example sudo mkfs -t nilfs2 /dev/mmcblkXp1 )
- Mount the newly created nilfs2 partition to /mnt ( sudo mount -t nilfs2 /dev/mmcblkXp1 /mnt )
- Unpack the ubuntu base and modules to /mnt ( with sudo tar xavf Ubuntu5.tar.lzma --numeric-owner -C /mnt and sudo tar xavf modules-4dd097f.tbz2 --numeric-owner -C /mnt )
- Umount the sd-card and set it aside for a while
- Power off your ac100, connect an usb cable from ac100 to your linux machine and power on the ac100 while pressing crtl+esc. The screen on the ac100 should remain off and the power led should light up.
- Surf to the folder where you unpacked the .run file from nvidia and take backup at least of the partition you're going to flash ( with sudo LD_LIBRARY_PATH=./nvflash/ ./nvflash/nvflash --bl ./prebuilt/fastboot.stock.bin --read 5 tegra_partition_5.bin --go )
- Power down the ac100 first and then power on again with ctrl+esc.
- You can flash either part 5 or part 6 with the boot.img. The Following command flashes part 5. Flashing part 6 makes the ac100 boot straight into ubuntu, but destroys android ( sudo LD_LIBRARY_PATH=./nvflash/ ./nvflash/nvflash --wait --bl ./prebuilt/fastboot.stock.bin --download 5 /the/path/to/boot.img --go )
- Nvflash should say that the flashing was succesfull and you can power off the ac100 by pressing the power button for a few seconds.
- Stick the sd-card to the ac100 and power on while pressing home and select 1 (if you flashed part 6, you won't have to press home)
- You should soon get in front of the typical ubuntu setup assistant, which will ask you your name, where you live etc.
- Edit /L4T/etc/X11/xorg.conf, so your alt+gr key gets recognized properly ( add Option "XkbModel" "pc105" and Option "XkbLayout" "fi" the last argument is the countrycode )
- fetch the lid-switch-daemon, install it in /usr/sbin, and edit /etc/rc.local so it is launched with "-b" or "-s" -- it will put the box to sleep when you close the lid
- while you're editing /etc/rc.local, replace /button by /usr/sbin/button
- Wifi works by first entering echo 1 > /proc/test_program/wifi3g and then sudo ifconfig ra0 down and sudo ifconfig ra0 up (you can also add this to your rc.local to get wifi working straight from the boot).
- Now do sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade and get nilfs-tools (you should also read about maintaining nilfs).
Installing on the internal emmc works the same way.
Just use usb and androids usb-file sharing to connect the ac100 partition 14 to your linux-machine and don't create a new partition, just format it and follow instructions above.
