How to Compile Raspbian on the Raspbian?
How to compile Raspbian on the Raspbian?¶
Introduction
Do you know we can compile Rsapbian on the Raspbian. To make your new Operation System. There are two good tool-chain and Raspbian source code and then you are dreaming to become true. It is very funny. You just need to another SD Card. Firstly, we have to download armv6 tool-chain and extract it. Secondly, [2] we need to download Raspbian source code and extract it. Thirdly, we have to arrange the environment variable to compile it.
Equipment
Operation System: Raspbian (NOOBS v1.3.10)
Armv6 Tool-Chain: gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux
Raspbian Source Code: raspi-linux-3.12.y
Usage
1.. To Extract armv6 Tool-Cahin.
root@raspberrypi:/home/pi/development# tar -xvf gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux.tar.xz
gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/

2.. If you realize time stamp in the future, it is a incorrectly. Because Raspberry isn't a battery, so if you are powered off and then it will turn to default. We need to set current date by this command-line (date –set=yyyy-mm-dd). However, Raspberry pi operates in the SD Card and you need to patient waiting long time to extract it.
root@raspberrypi:/home/pi/development/linux# date –set=2015-01-05
root@raspberrypi:/home/pi/development# tar -jxvf -P raspi-linux-3.12.y.tar.bz2
tar: ./linux/.git/hooks/pre-applypatch.sample: time stamp 2014-11-16 05:32:28 is 5760991.968545 s in the future
./linux/.git/index
tar: ./linux/.git/hooks: time stamp 2014-11-16 05:32:28 is 5760991.965893 s in the future
tar: ./linux/.git/index: time stamp 2014-11-16 05:42:31 is 5761590.406329 s in the future

3.. Preparing your development environment.
root@raspberrypi:/home/pi/development# cd /linux/
root@raspberrypi:/home/pi/development/linux# cp /proc/config.gz ./
root@raspberrypi:/home/pi/development/linux# ls
arch crypto include kernel net security
block Documentation init lib README sound
config.gz drivers ipc MAINTAINERS REPORTING-BUGS tools
COPYING firmware Kbuild Makefile samples usr
CREDITS fs Kconfig mm scripts virt
root@raspberrypi:/home/pi/development/linux# cp /proc/config.gz ./
root@raspberrypi:/home/pi/development/linux# mv config config.bak
root@raspberrypi:/home/pi/development/linux# gzip -d config.gz
root@raspberrypi:/home/pi/development/linux# mv config .config
To open the .bashrc of your home folder and then edit it. We need to arrange the environment variable. Please add as below into your .bashrc.
export KERNEL_SRC=/home/pi/development/linux
export CCPREFIX=/home/pi/development/gcc-linaro-arm-linux-gnueabihf-4.8-2014.04_linux/bin/arm-linux-gnueabihf-
export ARM=arm

5.. To establish Kernel.img.

6.. To make new modules.

7.. To update new kernel.img, modules and firmware.
If you are following the above instructions, you should make two folders, including modules and firmware. The ‘kernel.img’ should replace to overwrite put it in the BOOT partition. In the root partition, there is a folder called 'lib'. You are just overwriting your new modules and firmware put them into the folder. To update your modules and firmware, you should use 'su' or 'sudo' to operate these instructions and then you will avoid permission issues. In my opinion, I suggest removing old modules and firmware folders and then to copy new modules and firmware. That's the best way.
Exception
1.. While you were adding .bashrc, Don't added any space in variable line.
2.. If you encounter to choice, you could press 'enter' key to default. It is just fine.

Acknowledge
Thank you (Raspbian) very much for this great operation system.
