+C-SKY Development Kit
+
+Intro
+=====
+
+C-SKY is a CPU Architecture from www.c-sky.com and has it own instruction set.
+Just like arm and mips in linux/arch, it named as 'csky'.
+
+gx6605s develop board is made by Hangzhou Nationalchip and C-SKY.
+
+Hardware Spec:
+  * CPU: ck610 up to 594Mhz
+  * Integrate with 64MB ddr2 in SOC.
+  * Integrate with hardware Jtag.
+  * Integrate with usb-to-serial chip.
+  * USB ehci controller in SOC.
+  * Power Supply: DC 5V from two micro-usb.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+The csky_gx6605s_defconfig configuration is a sample configuration with
+all that is required to bring the gx6605s Development Board:
+
+  $ make csky_gx6605s_defconfig
+
+Build everything
+----------------
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+  $ make
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    +-- vmlinux
+    +-- rootfs.ext2
+    +-- <board name>.dtb
+
+How to run it
+=============
+
+Prepare Jtag-Server
+-------------------
+
+  Download the Jtag-Server here:
+
+  https://github.com/c-sky/tools/raw/master/DebugServerConsole-linux-x86_64-V4.2.00-20161213.tar.gz
+
+  Go to the unpacked directory:
+
+  $./DebugServerConsole -ddc -rstwait 1000 -prereset -port 1025
+
+  Perhaps you need to use "sudo", which need libusb to detect c510:b210
+
+  $ sudo ./DebugServerConsole -ddc -rstwait 1000 -prereset -port 1025
+
+Prepare USB drive
+-----------------
+
+  You sould determine which device associated to the usb drive
+  carefully. eg:
+
+  $ cat /proc/partitions
+   8       48    1971712 sdd
+   8       49     976720 sdd1
+
+  $ sudo dd if=rootfs.ext2 of=/dev/sdd1
+  $ sudo sync
+
+Run
+---
+
+  Plug the usb drive on gx6605s dev board.
+
+  Setup the Console with the rate 115200/8-N-1.
+
+  $ cd output/images
+  $ ../host/bin/csky-linux-gdb -x ../../board/csky/gx6605s/gdbinit vmlinux
+
