1. Do a local copy of the Asure’s kernel sources

$ git clone git://github.com/Asure/Dropad-kernel-2.6.35.7

2. Copy kernel config for Dropad A8

$ cp arch/arm/configs/dropad_defconfig .config

3. Select config parameters

ARCH=arm make menuconfig

4. Build process

ARCH=arm CROSS_COMPILE=arm-linux- make prepare
ARCH=arm CROSS_COMPILE=arm-linux- make modules_prepare
ARCH=arm CROSS_COMPILE=arm-linux- make M=net/can
ARCH=arm CROSS_COMPILE=arm-linux- make M=drivers/net/can

Doing this we get a the compiled module binaries of the SocketCAN subsystem for the Dropad A8 :D
