Linux Kernel source code for the devices:
Specific sources are separated by branches and each version is tagged with it's corresponding number. First, you should clone the project:
$ git clone https://github.com/bq/aquaris-E4.5.git
After it, choose the version you would like to build:
Aquaris E4.5
$ mv aquaris-E4.5 kernel
$ cd kernel
$ git checkout aquaris-E4.5_2.x
At the same level of the "kernel" directory:
Download a prebuilt gcc
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8
Create KERNEL_OUT dir:
$ mkdir KERNEL_OUT
Your directory tree should look like this:
Finally, build the kernel according the next table of product names:
device | product |
---|---|
bq aquaris E4.5 | krillin |
$ make -C kernel O=../KERNEL_OUT ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi- {product}_defconfig
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi-
You can specify "-j CORES" argument to speed-up your compilation, example:
$ make O=../KERNEL_OUT/ -C kernel ARCH=arm CROSS_COMPILE=../arm-eabi-4.8/bin/arm-eabi- -j 8
