ARM Notes:
1--Using the Jlink in Linux Operating System:=1= Install the libusb library:
sudo apt-get install libusb-dev
=2= Download The Jlink Driver for Linux
Unzip the Driver,Enter the Directory:
Run the Command below in the terminate with root Right to Copy the shared libraries to /usr/lib directory:
mv libjlinkarm.so.4/usr/lib/
mv libjlinkarm.so.4.22.0/usr/lib/
=3=Now We Can Run the JlinkExe or Start file to Run the software:
sudo ./start
or
sudo ./JlinkExe 2--Use the PUTTY instead of SecureCRT in Ubuntu Linux
=1=Install ssh protocol :
sudo apt-get install ssh
=2=Install the FTP Server vsftp
sudo apt-get install vsftp
After installed , it must be configured and restart
=3=Use the FileZilla replace the CuteFTP.
Before use the putty to visit the other linux OS , you must make sure the firewall has been closed or properly configured . 3-- Install the Serial Soft And Export the linux-arm-gcc to the PATH

ubuntu下ARM开发环境的配置
以下配置是个人总结，在自己的电脑上测试通过，按此方法配置请根据自身情况修改
一般C语言开发环境的安装：
sudo apt-get install build-essential
Minicom的安装：
#lsmod | grep usbserial
#sudo apt-get install minicom
#minicom -s /配置minicom
A-Serial Device:/dev/ttyUSB0 因为我是USB转串口
E-Bps/Par/Bits:115200 8N1
F和G均用NO
然后保存为dfl
tftp的安装：
sudo apt-get install tftp-hpa tftpd-hpa
sudo apt-get install xinetd
建立tftp服务的目录
cd /
sudo mkdir /tftpboot
sudo chmod 777 /tftpboot
sudo gedit /etc/xinetd.d/tftp
文件内容如下：
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot -c
per_source = 11
cps = 100 2
}
然后sudo /etc/init.d/xinetd restart
sudo in.tftpd -l /tftpboot
用网线连接计算机和开发板后，设置好计算机的IP地址，然后打开tftp服务，进入开发板终端，输入tftp -gr filename 计算机IP 便可下载程序，程序必须位于/tftpboot下
将有线网卡的IP地址设为静态：
sudo gedit /etc/network/interfaces
加入以下几行
auto eth0
iface eth0 inet static
address 192.168.1.88
gateway 192.168.1.1
netmask 255.255.255.0
arm-linux-gcc的安装：
下载包后，在/usr/local/下建立名为arm的文件夹，然后解压缩，将里面的bin文件夹添加到环境变量,方法如下
sudo gedit /etc/profile
在后面加入export PATH="$PATH:/usr/local/arm/2.95.3/bin"，根据版本不同文件夹名字也不一样，bin目录下有arm-linux-***一些文件就是我们要找的，然后注销使环境变量生效
echo $PATH可以看看设置是否成功
像一般的C一样写个hello.c
然后arm-linux-gcc hello.c -o hello
编译好的hello在ubuntu下运行不了，可以./hello试下
用上面的tftp把hello弄到开发板的/tmp目录下，然后chmod 777 hello后就可以运行了 /*usb2ram.cGNU License*/

usb2ram软件下载地址：
http://forum.ubuntu.org.cn/viewtopic.php?f=97&t=107504
下载下来的压缩包中解压后是有一个可执行文件的，但是这个可执行文件一般不能执行，需要在自己的系统上重新编译才能用
首先要修改Makefile文件，在第一行之后添加如下这行，用以设定编译器：
CC=gcc
修改之后的Makefile文件如下：
#!/usr/bin/make
CC=gcc
LDFLAGS=-lusb -lm
all: usb2ram
clean:
-rm -f *.o usb2ram
usb2ram: usb2ram.o
$(CC) $(LDFLAGS) -o $@ $<
boot_usb.o: boot_usb.c
$(CC) $(CFLAGS) -o $@ -c $<
.PHONEY: all clean
编译前先清除无用的文件，以确保后面能够正常编译，这时执行一下命令：
make clean
再次编译前要确保有libusb 和libusb-dev两个库，我是看的网上文章的提示。若是没有，编译时就会提示：
cc -lusb -lm -o usb2ram usb2ram.o
/usr/bin/ld: cannot find -lusb
collect2: ld returned 1 exit status
make: *** 错误 1
于是我就输入命令： sudo apt-get install libusb libusb-dev进行两个库的安装
这时又有提示：
正在读取软件包列表... 完成
正在分析软件包的依赖关系树
正在读取状态信息... 完成
E: 无法找到软件包 libusb
说是找不到libusb，这时我就输入如下命令：
sudo apt-get install libusb-dev
只安装libusb-dev这个库，这个库可以找的到，安装好之后再make，就成功生成了usb2ram可执行文件
下面讲讲它的用法：
我用的是TQ2440的开发板，首先确保norflash里面有bootloader，这时选择从norflash启动，
出现如下菜单界面：
##### Boot for Nand Flash Main Menu#####
Download u-boot to Nand Flash
Download Eboot
Download Linux Kernel
Download WinCE NK.bin
Download CRAMFS image
Download YAFFS image
Download to SDRAM & Run
Boot the system
Format the Nand Flash
Set the boot parameters
Download User Program
Download LOGO Picture (.bmp) to NandFlash
Set LCD Parameters
Reboot u-boot
quit from menu
Enter your selection：1
在这里我选择的是1:下载uboot到nandflash
这时终端提示：
USB host is connected. Waiting a download.
表示你现在可以使用usb2ram软件下载镜像文件了
这时启动另外一个终端，进入usb2ram可执行文件所在的目录，输入一下命令：
sudo ./usb2ram 30000000 /home/deng/ARM/images/u-boot_W35.bin
这个命令的形式是：sudo ./usb2ram地址文件
一开始在命令之前没有加sudo，提示如下错误：
Unable to claim usb interface 1 of device: could not claim interface 0: Operation not permitted
加上之后就好了
现在切换到由nandflash启动，启动时按住空格建进入下载模式，这时跟norflash启动效果一样，说明uboot已经下载到了nandflash中
也可以用同样的方法将其他的镜像下载只开发板 CH340 CH341 , USBToRS232 Driver for Windows 7 X64:
(验证可用的CH340,CH241的USB转RS232 在windows 7 64位系统下的驱动):

<1> Copy the Installer to the Ubuntu Filesystem : eg copy to the home directory
<2> sudo chomd 777 VWware****.bundle
