Source Readme 
=============
 Cubietech have opened the linux sdk to community for cubieboard4,you can 
get the kernel source,u-boot,and rootfs, you can compile the sdk to pack 
a firmware for a tf card booting ,or pack a tf card firmware to flash cb4 
emmc. Now,We have release debian and ubuntu distrabution,this is just a 
start ,you can develop your own distrabutions , thanks for you support for 
cubieboards community.

Build sdcard image:
	1. tf card boot
	(1)cb_build_card_image (compile code to prepare cb_install_tfcard)
	(2)cb_part_install_tfcard dev_label
		dev_label:      sdb sdc sdd ...
	(3)cb_install_tfcard  dev_label [pack]
		dev_label:      sdb sdc sdd ...
		pack:           the parameter mean we will make a img for dd or win32writer
		cmd for example: cb_install_tfcard sdb

        2. emmc card boot
	(1)cb_build_flash_card_image (compile code to prepare cb_install_flash_card)
	(2)cb_part_install_flash_card dev_label
		dev_label:      sdb sdc sdd ...
	(3)cb_install_flash_card dev_label [pack]
               (install TF card to flash img to emmc)
		dev_label:      sdb sdc sdd ...
		pack:           the parameter mean we will make a img for dd or win32writer
		cmd for example: cb_install_flash_card sdb
