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 +-- .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
