# DEV TOOLS#

Install Nvidia linux4tegra development tools [here](http://developer.nvidia.com/tegra/downloads)  :

`cd ~`
`mkdir ac100`
`cd ac100`
`wget http://developer.download.nvidia.com/tegra/files/linux_for_tegra_os_pack_rel_20101029_10.9.3.run.tar.gz`
`tar -zxvf linux_for_tegra_os_pack_rel_20101029_10.9.3.run.tar.gz`
`sh ./linux_for_tegra_os_pack_rel_10.9.3.run`


# BACKUP#

`cd ~/ac100`
`cd linux4tegra/nvflash/`

Completely power off your AC100 : hold **"Power switch"** for 10s

Plug and USB to micro-USB cable, form your AC100 (micro-USB), and your computer (USB)

Press **CTRL** + **ESC** keys continuously  and press  **"Power switch"** for 3 sec. 
Release   **"Power switch"**, withe led will turn on in 2-3 second, release **CTRL** + **ESC** keys

become root : `su` or `sudo su` 

`LD_LIBRARY_PATH=. ./nvflash --bl ../prebuilt/fastboot.stock.bin --go`
`LD_LIBRARY_PATH=. ./nvflash -r --getpartitiontable partitiontable.txt`
`LD_LIBRARY_PATH=. ./nvflash -r --read 2 part-2.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 3 part-3.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 4 part-4.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 5 part-5.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 6 part-6.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 7 part-7.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 8 part-8.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 9 part-9.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 10 part-10.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 11 part-11.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 12 part-12.img`
`LD_LIBRARY_PATH=. ./nvflash -r --read 13 part-13.img`

As part 14 is user data, if you have no data, you can jump this step.
`LD_LIBRARY_PATH=. ./nvflash -r --read 14 part-14.img` (very,very,very long and end with an error : it's normal don't panic)


Completely power off your AC100 : hold **"Power switch"** for 10s (release when screen blink.)

# INSTALL phh UBUNTU #

**GET FILES**

`cd ~/ac100`
`wget http://kotelett.no/ac100/phh/boot.img`
`wget http://kotelett.no/ac100/phh/Ubuntu5.tar.lzma`

** GET YOUR KERNEL PARAMETER **

if not in : [[CommandLine]]

boot android and install : Term.apk  from [here](http://code.google.com/p/androidterm/downloads/list)

Install : Term.apk

Open Terminal application previously installed

put an SDCARD or USB KEY

type : 
`mount`
find line where your sdcard or key are : 
example : /storage/sdcard0-disk1

type : 
`dmesg > /storage/sdcard0-disk1/dmesg.log`
`sync`

power off your AC100

Go to your Main computer, mount the sdcard : 

type : 
`cat /pathto:yourmoutedsdcard/ dmesg.log | grep "command line"`

result something like this : 

`<5>[    0.000000] Kernel command line: mem=448M@0M nvmem=64M@448M vmalloc=320M video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:300:a00:800,boot:d00:1000:800,mbr:1d00:200:800,system:1f00:25800:800,cache:27700:32000:800,misc:59700:400:800,userdata:59c00:9a600:800 `

now : 

`cd ~/ac100`
`wget http://ac100.gudinna.com/internal/bootimg.tar.gz`
`tar -zxvf bootimg.tar.gz`
`cd bootimg`
`make`
`cp ../boot.img ./`
`./unpack_bootimg boot.img`

**replace the value by your result above in order to have : **
`./make_bootimg boot.img zImage initrd.img -c 'mem=448M@0M nvmem=64M@448M vmalloc=320M video=tegrafb console=tty0 usbcore.old_scheme_first=1 quiet splash elevator=noop tegraboot=sdmmc tegrapart=recovery:300:a00:800,boot:d00:1000:800,mbr:1d00:200:800,system:1f00:25800:800,cache:27700:32000:800,misc:59700:400:800,userdata:59c00:9a600:800'`

`cp ./boot.img ../myboot.img`

**or just update the boot comand line in downloaded boot.img via abootimg**
(confirmed to work on debian 6) https://gitorious.org/ac100/abootimg#more

syntax:
$ abootimg -u boot.img -c "cmdline = mem=448M@0M nvmem=64M@448M vmalloc=320M  video=tegrafb console=tty0 usbcore.old_scheme_first=1 quiet splash elevator=noop tegraboot=sdmmc tegrapart=recovery:700:a00:800,boot:1100:1000:800,mbr:2100:200:800,system:2300:25800:800,cache:27b00:32000:800,misc:59b00:400:800,userdata:5a000:9a600:800"

             **replace the value "cmdline.... " by your result (cmdline) above.**

example result : -> sd 14:0:0:0: [**sdc**] 7821183 512-byte logical blocks: (**4.00 GB**/3.72 GiB)

** VERIFY sdc and size** to avoid destroying your main system !!

become root : `su` or `sudo su` 
`umount /dev/sdc1`
`umount /dev/sdc2`
`umount /dev/sdc3`
...

`fdisk /dev/sdc`

verify : one only partition ( ' p ' to print)
verify type of partition : ( ' t ' partition 1, type 83 )
save '  wq '
