-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
