Changes

The Dacu system is provided with a pre-programmed Android environment. When started (please refer to [[Dacu#Quick_start | Dacu Quick Start]]), the bootloader loads the Android kernel and mounts the default root file system retrieving these components from the flash. For further information on the boot process, please refer to [http://elinux.org/Android_Booting Android Booting].

In some cases (in particular during the development phase) it's required to boot the system loading different kernel images or root file systems. You can do this by setting up Dacu to load the kernel and root file sustem from the network, using tftp and nfs protocols. Please refer to [[Setting_up_tftp_and_nfs]] for instruction on how to install a tftp and nfs servers on the host environment. When the TFTP and NFS services are properly configured, copy the kernel image to the tftp directory (es: /tftpboot/dacu/android/uImage) and export via NFS the directory where the root file system archive has been previously uncompressed.
