昨天突然感冒了，整个人都不好了，好从下午上班到下班，感觉到体力就像质量非常好的下降沿，突然没劲了，好不容易爬回了家，倒头就睡，经过了一天的调养，身体恢复点了，既然有体力了，那就继续计算机世界的探险吧
下面的内容，是吧ｂｕｉｌｄｒｏｏｔ安装到开发板上进行运行，解决有无问题，能在开发板上运行后，后期就是根据需要，按个添加工具了
YL-9g45平台，buildroot移植
1、硬件平台资源
（1）400MHz at91sam9g45处理器
（2）128MByte DDR2SDRAM
（3）256MByte NANDFLASH
（4）10/100Mbps以太网
（5）1个USB HOST端口
（6）1个DBUG串口，用于console登陆，一个usb device端口，用于操作系统的烧写
2、软件平台
使用buildroot2016.05稳定版
（1）解压buildroot压缩包，进入解压后的目录
（2）选择参考平台
make list-defconfigs 列举出当前的参考平台
我选择的是at91sam9g45m10ek_defconfig
make at91sam9g45m10ek_defconfig 使用配置选项
（3）平台配置
make menuconfig 进入配置界面
（4）选择交叉编译工具
在toolchain -->选项中进行配置使用Sourcery CodeBench ARM 2014.05
（5）选择bootstrap版本
在bootloads--> 选项中，配置AT91 Bootstrap3
下载地址为：git://github.com/linux4sam/at91bootstrap.git
版本为：at91bootstrap-3.5.x
（6）选择uboot版本
在bootloads--> 选项中，配置AT91 Bootstrap3
下载地址为：git://github.com/linux4sam/u-boot-at91.git
版本为：u-boot-2016.03-at91
（7）linux-kernel
在kernel-->选项中，配置
下载地址为：https://github.com/linux4sam/linux-at91.git
版本为：linux-4.4-at91
load address 为：0x70008000
（8）根文件系统类型
在Filesystem image-->选项中，使用ubifs文件系统类型配置
更改maximum logical eraseblock count为：1919
（9）下载所需资源
在buildroot根目录下，使用命令:make source，进行源码下载
（10）更改内核对根文件系统的分区
进入./dl文件夹，解压linux-linux-4.4-at91.tar.gz
进入linux-linux-4.4-at91/arch/arm/boot/dts/
修改文件vi at91sam9m10g45ek.dts
修改nandflash分区为，我只有两个分区，第一个分区放置，启动代码和内核8MByte，第二个分区放置根文件系统248MByte
保存退出，删除之前的linux-linux-4.4-at91.tar.gz，将现在的linux-linux-4.4-at91目录，压缩成linux-linux-4.4-at91.tar.gz。
（11）编译工程
回到buildroot根目录，使用make命令进行工程编译。
在output/image/下生成烧写文件
nandflash地址划分如下：
0x0 ~ 0x40000 AT91Bootstrap(256KByte)
0x40000 ~ 0xc0000 uboot(512KByte)
0xc0000 ~ 0x100000 uboot_env(256KByte)
0x100000 ~0x140000 uboot_env_Redundant(256KByte)
0x140000 ~ 0x180000 unuse
0x180000 ~ 0x200000 Device Tree(dtb) (512KByte)
0x200000 ~ 0x800000 linux-kernel (6MByte)
0x800000 ~ 0x10000000 Rootfs (248MByte)
samba烧写方式：
at91sam9m10g45ek-nandflashboot-uboot-3.6.0.bin 使用send file file
u-boot.bin 烧写到0x40000地址
u-boot_env 烧写到0xc0000地址
at91sam9m10g45ek.dtb 烧写到0x180000地址
uImage 烧写到 0x200000地址
rootfs.ubi 烧写到0x800000地址
（12）uboot环境变量
baudrate=115200
bootargs=mem=128M console=ttyS0,115200 root=/dev/mtdblock1 rw rootfstype=ubifs ubi.mtd=1 root=ubi0:rootfs
bootargs_net=mem=128M console=ttyS0,115200 root=/dev/nfs ip=192.150.100.201 nfsroot=192.150.100.101:/home/shirf/nfs_file/rootfs,v3,tcp
bootcmd=run bootcmd_nand
bootcmd_nand=nand read 0x71000000 0x180000 0x80000;nand read 0x72000000 0x200000 0x600000;bootm 0x72000000 - 0x71000000
bootcmd_net=setenv bootargs ${bootargs_net};tftp 0x71000000 at91sam9m10g45ek.dtb;tftp 0x72000000 uImage;bootm 0x72000000 - 0x71000000
bootdelay=3
ethact=macb0
ethaddr=32:22:29:99:03:6d
ipaddr=192.150.100.201
serverip=192.150.100.101
通过setenv命令进行环境变量的设置
当然环境变量设置好之后，通过samba读取存储在nandflash中的环境变量，起始地址：0xc0000 长度：0x80000，保存称文件名为：uboot_env,这个参数可以按照烧写步骤进行烧写。这个参数里包含环境变量和环境变量校验和
我从开发板上下载下来的环境变量可以通过下面方式下载

输入root即可通过串口控制台登陆，当然你可以设置root登陆密码。现在完成移植后系统在开发板上加电工作正常。
（14）通过网络下载内核，挂载根文件系统，方便内核调试
设置uboot的环境变量，将bootcmd=run bootcmd_nand 改为bootcmd=run bootcmd_net
uboot环境变量中，设置宿主机IP为serverip=192.150.100.101 ；开发板IP为ipaddr=192.150.100.201 。
bootcmd_net=setenv bootargs ${bootargs_net};tftp 0x71000000 at91sam9m10g45ek.dtb;tftp 0x72000000 uImage;bootm 0x72000000 – 0x71000000
以上环境变量为，从tftp服务器上下载 at91sam9m10g45ek.dtb 到0x71000000， uImage到 0x72000000，启动内核bootm 0x72000000 – 0x71000000
bootargs_net=mem=128M console=ttyS0,115200 root=/dev/nfs ip=192.150.100.201 nfsroot=192.150.100.101:/home/shirf/nfs_file/rootfs,v3,tcp
以上变量为，挂载根文件系统为 192.150.100.101:/home/shirf/nfs_file/rootfs
这个路径跟你的nfs服务器有关系
查看宿主机tftp的设置
/etc/xinetd.d/tftp
其中server_args = -s /home/shirf/my_explore/tftp_file/ 为我的tftp服务器目录，我需要将at91sam9m10g45ek.dtb、 uImage复制到该目录下
查看宿主机nfs的设置
/etc/exports
/home/shirf/nfs_file *(rw,sync,no_root_squash)
我的nfs共享目录地址为/home/shirf/nfs_file，允许所有IP访问，当连接互联网时，需要设置好网络过滤规则。
复制at91sam9m10g45ek.dtb、 uImage到我的tftp服务器文件夹下。
复制rootfs.tar到我的nfs服务器文件夹下，在该目录下建立rootfs目录mkdir rootfs，解压rootfs.tar到rootfs目录下sudo tar -xf rootfs.tar -C rootfs/
从网络启动内核和挂载根文件系统输出信息：
