I'm trying to understand correctly how Android is running on my SABRESD board.
I would like to know what are the significant changes that are brought by Freescale in kernel_imx ?
The imx_v7_android_defconfig is a defconfig generated by Freescale and I would wand to know if this defconfig is really different of the execute of android script :
scripts/kconfig/merge_config.sh arch/arm/configs/imx_v6_v7_defconfig android/configs/android-base.cfg
Which version of the BSP you are talking about?
Please download the Android BSP documentation, there is a Android User's guide.
Basically, following the steps in user's guide you will know how we change/patch the source code.
