Compiling X10 kernel sources
As I was told Sony released Xperias X100 kernel sources I decided to play a little with them. This tutorial is for advanced users by the way as you need some linux knowledge (wrote it from memory as I did it one day ago).
As I'm new to cross compiling it took me a while to configure the platform correctly (I did it on Ubuntu 10.04).
- Get the sources here : http://developer.sonyericsson.com/wp...01?cc=gb&lc=en
- Tutorial to set up the environment correctly : : http://source.android.com/source/download.html
- the make config file is available in the phone under '/proc/config.gz'
and 'adb pull /proc/config.gz'
* So after you set up everything as described in the android.com page in ubuntu :
- mkdir x10
- copy the kernel sources and config.gz to the x10 folder
- gunzip X10_Donut_100325_01.tar.gz
- tar -xvf X10_Donut_100325_01.tar
- go to the kernel directory in the X10_Donut_100325_01 folder
- gunzip config.gz
- rename it to .config and move it to the kernel folder (mv config X10_Donut_100325_01/esheep_linux/LINUX/android/kernel/.config)
- make ARCH=arm CROSS_COMPILE=path-to-git-repo/prebuilt/linux-x86/arm-eabi-4.4.0/bin/arm-eabi- menuconfig to choose what to compile as module
- make ARCH=arm CROSS_COMPILE=path-to-git-repo/prebuilt/linux-x86/arm-eabi-4.4.0/bin/arm-eabi- modules
'path-to-git-rep' is the folder where your placed your git repository files
a long time after this modules are compiled from source !
* I know usb host mode was already made for nexus one :
So I looked in the Xperia kernel config and noticed usb-host was compiled with the current kernel.
I compiled the sources and added kernel modules as an attached file.
Unluckily I don't have a Powered USB 2.0 hub providing its power to the upstream port and a female usb connector to mini-usb so I cannot test if my kernel module is correctly compiled.
So if someone has this hardware please :
- copy those attached files to sdcard then
- adb shell
- su to get root
- 'busybox insmod /sdcard/usb-storage.ko'
- 'busybox lsmod' to check if module is loaded
- plug the usb hub to your X10
- plug an usb stick
- ' busybox dmesg | busybox tail' to get more infos and check if the stick is detected, if yes tell me
I also compiled the usb-serial modules so if someone has an Arduino board you may plug it to your X10 now
Of course I have no guarantee this will work (this is my first cross compiling!) so feedback is welcome !
Also my tutorial is not very great, but I hope it may help few people here.
