configs: add defconfig for Nationalchip gx6605s dev board
gx6605s is a nice SOC for dvbs2 DVB product, and C-SKY inside. Signed-off-by: Guo Ren <ren_guo@c-sky.com> [Thomas: drop post-image script copying the gdbinit file, and suggest to use gdb -x option instead to point to the gdbinit file in board/.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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