Hello guys !!!
So I am endrix and I am trying to port the linux kernel to our Toshiba TG01. I am an h.264 developer who loves linux. Many of you may hate the phone (I do a little too) because of the crappy windows mobile operating system that Toshiba has offered us. Beside the resistive touch screen our phones have a strong processor that is used almost in each smartphone (ok Samsung and Apple are not using snapdragon but is still Cortex A8).
So to the main point!
Firstly is not an easy task and I do not somebody to write in this thread when Android will work with our phones, I truly do not know if I will (or we will) achieve this! Secondly think to contribute as you can to this project, I am here to guide you if you have any questions about how to compile the kernel and if you have any other problem just send me a message or write it in this thread!
My git repository of the TG01 kernel is this one
System compilers and libraries:
I used the one given by source.android.com
apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev.
certainly you do not need all of them but is ok to have it
So how can you compile the kernel?
- Use an Ubuntu Linux distribution or virtualise it with Virtualbox
- I am using this cross tools: arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2"
- in my system I have created a directory in my /opt folder, to that just do "sudo mkdir /opt/cross"
- Now go to the directory with "cd /opt/cross"
- now rember where you have download the tar archieve and execute the following command, in this command i have downloaded my tar in /home/endrix/Download: so for my directory I do " tar xjvf /home/endrix/Downloads/gnueabi-i686-pc-linux-gnu.tar.bz2"
- Now that we have our cross tools installed in our system is it good to create an eviromental varibale to easy our task of ceoss compiling. do this command "gedit ~/.bashrc" and at the end of the file put this line: export CROSS_TOOLS=/opt/cross/arm-2009q1/bin/arm-none-linux-gnueabi-
- now execute this command "source ~/.bashrc" so that you command can be activated for the current command, the next time that you will open another console or reboot the varibale $CROSS_TOOLS will work
- This is all for the cross tools
Next step Compile the linux kernel:
- Create a directory for example "Projects" in your main directory(home), "mkdir ~/Projects"
- Clone the repository of my git address: "git clone github.com/endrix/kernel_common.git"
- Now you wait, take a coffe or eat a fruit
- now you execute this command in the "kernel_common" directory, "make ARCH=arm htcleo_defconfig"
- and then to compile the kernel" make ARCH=arm CROSS_COMPILE=$CROSS_TOOLS Image"
- To make the process even faster if you have a multicore system, put -j4 (for 2 cores) or -j16 (if you have an intel iCore7 with 4 cores double threaded), that means, "make -j4 ARCH=arm CROSS_COMPILE=$CROSS_TOOLS Image"
- After a while depending you system you will get the kernel image file in the arch/arm/boot directory
- So now you have the kernel compiled
Next step test the kernel with Haret:
1) Create the file default.txt with :
set mtype 2675
set ramaddr 0x11800000
set ramsize 0x18C00000
set kernel Image
2)Download My modified version of Haret with TG01 support!
Haret for TG01
3)Create a folder in your sd card --> "ToshDroid and put the Image the haret.exe and the default.txt in it.
4) Finally execute the haret.ext and clik on run!
That's all folks! Now I am focusing in the Memory Map...
PS: sorry for links, As a junior member i cannot give a full url
I will update also my blog too for TG01
