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
|
