AT91SAM9260 嵌入式开发板（C 版本）
（订购型号：）
AT91SAM9260 ARM工控主板是一款功能齐全、体积小巧、性能稳定、超低价格的嵌入式模块产品。模块硬件完全按工业级标准设计，CPU采用了ATMEL公司32位工业级ARM9芯片（AT91SAM9260），主频达到200MHz，PCB板经精心优化设计，除提供全面、高效的功能之外，还较好地控制了模块功耗。
配备了完备的通讯和输入输出接口，包括1个100M快速以太网，6个标准异步串口，1个CAN总线接口，2个USB HOST及1个USB Device接口，能够满足大多数工业应用的需要。同时，EM9260还提供了LCD接口（支持大多数单色和部分彩色LCD）以及矩阵键盘接口，使用户很容易构成所需的智能终端。EM9260板上带有64MB系统内存、256MB
FLASH存储空间，并支持SD卡应用存储扩展。EM9260的精简ISA扩展总线则为客户扩展各种应用单元提供了简单高效的手段，用户可以不加任何接口电路，就与大多数的通讯接口控制芯片、AD-DA、DIO等器件直接相连或者进行双CAN扩展、多串口扩展以及多网口扩展等应用扩展。此外，EM9260有最多28位GPIO以及2路单端输入10-bit AD通道（与精简ISA总线复用，通过软件配置），实现多种应用组合。

因为9260编译后必须使这个烧入文件小于4K,所以要针对Makefile做修改:&
root@emboard:/workdir/atmel/at91sam9260/AT91Bootstrap/Bootstrap-v1.14/board/at91sam9260ek/nandflash# vim Makefile&
修改下面这个地方:

屏蔽掉你不用的nandflash,这样就可以使编译最后的大小小于4K!

root@emboard:/workdir/atmel/at91sam9260/u-boot/u-boot-1.3.4# make&
这样就可以编译出u-boot.bin&
可以去这个文件来看u-boot烧写进nandflash的地址&
root@emboard:/workdir/atmel/at91sam9260/AT91Bootstrap/Bootstrap-v1.14/board/at91sam9260ek/nandflash# vim at91sam9260ek.h&

/* ******************************************************************* */
#define IMG_ADDRESS &&0x20000&&/* Image Address in NandFlash */
#define&IMG_SIZE&&0x40000&&/* Image Size in NandFlash&&& */&
看到烧到nandflash的地址是:0x20000&
然后打开串口,写入进nandflash串口信息如下:&

然后配置:&

给建立服务器
首先设置虚拟机能上网步骤如下：
配置，配置文件
然后是，配置
例如：配置静态地址
内容如下：
增加以下内容：
增加默认网关
重新启动网络配置
建立服务器
网上摘抄方法
这样服务器就启动了，下面可以做一个测试
建立一个文件
登录另一个目录
换成自己的如果能够得到文件，那么就成功了。
：不要忘了关于不能上传（）的解决
打开目录新建文件内容：
重新启动服务：
安装过程中出现的问题及原因
服务没有启动
在中设置的为设置的时候只要将＝改为你自己设定的服务器文件夹就行了
指定的文件不存在；或启动参数中没有指定选项，允许上传文件。
板子通过下载虚拟机的文件
这样就可以直接下载文件到板子上了
当然你也可以下载其它的文件：

google下,知道是内核恐慌.原因是内核的
内核命令行有个环境变量。如果即将达到或者已经超过了的话参数会没有传进去启动时会引发错误。
所以去看uboot的参数传递，没有!
现在去看下u-boot

================================================
为什么我选择下面的这个内核配置会出现这个结果呢？&
选种的话，会自己自动创建MTD分&
500)this.width=500;& border=0&&
NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB 3,3V 8-bit)
AT91 NAND: 8-bit, Software ECC
Scanning device for bad blocks
6 cmdlinepart partitions found on MTD device at91_nand
Creating 6 MTD partitions on &at91_nand&:
0xx : &bootstrap&
0xx : &uboot&
0xx : &env1&
0xx000a0000 : &env2&
0x000aa0000 : &linux&
0x002a00000 : &root&&
不选中的话：500)this.width=500;& border=0&&
NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB 3,3V 8-bit)
AT91 NAND: 8-bit, Software ECC
Scanning device for bad blocks
Creating 6 MTD partitions on &NAND 256MiB 3,3V 8-bit&:
0xx : &Bootstrap&
0xx : &u-boot&
0xx01e00000 : &kernel&
0x01e00000 : &fs&
0xx : &user space0&&
0xx : &user space2&&
2,NFS文件系统搭建:&
安装服务器端和客户端
配置共享文件
编辑，在其中增加要共享的目录
客户就可以加载了
[root@microcreat /]$mount -o nolock -t nfs 192.168.1.5:/nfs/rootfs /mnt/
要加上-o nolock
内核里面关于nfs文件系统的选项选上
