+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
+    ??? .gdbinit
+
+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/usr/bin/csky-linux-gdb vmlinux
+
+  (csky-linux-gdb use .gdbinit to load vmlinux)
+

[Buildroot] [PATCH 1/1] configs: add defconfig for Nationalchip gx6605s dev board.

[ren_guo]

Here is the gx6605s Introduction video, hope it could help.

https://youtu.be/Y9gA1q9NA_Y

The goal of this development board is linux-kernel study for beginner.

I've applied the patch after doing one change, see below.

I've removed this entirely, and just changed the readme.txt
instructions to tell people to run:

  ./output/host/usr/bin/csky-linux-gdb -x board/csky/gx6605s/gdbinit output/images/vmlinux

By referencing the gdbinit file using the -x option, we don't have to
copy it around in an hidden file.

Thanks!

"gdb -x" is great, I like it :)

Now I'm preparing more for this board, and it's a big encouragement for me.
Thanks for your careful reviewing.

gdbinit need load gx6605s.dtb to a memory address, so we need run it  in output/images like this:

$ cd output/images

$ ../host/usr/bin/csky-linux-gdb -x board/csky/gx6605s/gdbinit vmlinux

Best Regards

Or change gdbinit to:

restore output/images/gx6605s.dtb binary 0x92000000

It won't work for "make O=/tmp/br".

Update readme.txt is OK.

Right, but the readme.txt instructions do assume anyway that the output
is in output/images. But OK, the user can easily adjust by himself the
instructions he is copy/pasting from readme.txt and be confused by a
hardcoded path in the gdbinit file.

> Update readme.txt is OK.

OK, then please send a patch, but you also need to change the relative
path to the gdbinit file, it was not correct in your example, it should
be:

	-x ../../board/csky/...

Yes, it's wrong in my example, and I want use post-image.sh to copy the gdbinit to the output/images.

and the readme will be changed like this:

$ cd output/images

$ ../host/usr/bin/csky-linux-gdb -x gdbinit vmlinux

I think it's a bit annoying/useless to copy the gdbinit file around.
Why not keep it where it is?
