如何启动 FreeBSD

Ganbold，一个FreeBSD开发者，现在搞定了在Rockchip平台上的FreeBSD引导工作。Ganbold 告诉我们只有基本模块、GPIO、DWC

USB主机模式可以工作。但这只是个开始，如果你感兴趣，在#radxa的免费IRC频道联系Ganbold，以获取更详细的资料。

请看 FreeBSD ARM wiki的介绍:

https://wiki.freebsd.org/FreeBSD/arm/Radxa%20Rock

使用Ubuntu 13.10 amd64 并且使用rkflashtool 编译的请注意：

通过 sudo apt-get -y install libusb-1.0-0-dev来安装 libusb.h
拔掉板子电源。然后按住Recovery按键，再连接USB线（连接到OTG接口的）到计算机，等3秒钟松开Recovery按键。如果此时RK3188没有进入Recovery模式，你在运行 ./rkflashtool p > param.txt 时，会出现：”rkflashtool: fatal: cannot open device”。
使用下面的Makefile：

#
all: rkflashtool

rkflashtool: rkflashtool.c
gcc -o rkflashtool rkflashtool.c -I/usr/include/libusb-1.0/ -lusb-1.0 -O2 -W -Wall

clean:
rm -f rkflashtool

param:
sudo ./rkflashtool r 0x0000 0x2000 > /tmp/parm
