2.2.8、查看处理器的性能模式与频率

T536处理器一共有4个核心，通过如下指令可以查看核心的运行频率是1.5GHZ。
Target# cat /sys/devices/system/cpu/cpu/cpufreq/cpuinfo_max_freq
//CPU最大频率，代表0-3

点击查看代码

root@T536-embfly:/# cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq
1512000
1512000
1512000
1512000
root@T536-embfly:/#

从以上信息可以得知，0-3核心工作的最高频率是1.5GHZ，另外还可以通过如下指令判断当前处理器的处于什么样的工作方式，例如性能模式还是省电模式：
Target# cat /sys/devices/system/cpu/cpu/cpufreq/scaling_available_governors
//可用的CPU工作模式，代表0-3
Target# cat /sys/devices/system/cpu/cpu/cpufreq/scaling_governor
//当前CPU运行模式，代表0-3
Target# cat /sys/devices/system/cpu/cpu/cpufreq/scaling_cur_freq
//当前CPU频率，代表0-3
处理器的工作模式有如下：

用于连接远程SSH服务器和安全文件传输，评估板根文件系统默认已支持SSH库。2.3、OpenSSH使用
OpenSSH是一个用于安全远程登录和其他安全网络服务的工具集，其组件包括：ssh、sshd、scp、sftp等。广泛

2.3.1、通过OpenSSH登录系统

在Ubuntu执行如下命令并输入密码root（默认用户名和密码均为：root/embfly）即可登录评估板根文件系统，执行exit或者logout命令退出登录。
Host#sudo ssh root@192.168.0.64 //192.168.0.64为评估板IP

2.3.2、使用scp拷贝文件

（1）从PC机传送文件至评估板
执行如下命令，将使用OpenSSH工具集中scp将test文件拷贝至评估板文件系统根目录。如传输的是文件夹，请在scp后面添加参数"-r"。
Host# scp test1 root@192.168.0.64:/

在评估板根目录可看到从PC机拷贝过来的文件，如下图所示：

（2）从评估板传送文件至PC机
在Ubuntu上执行如下命令将评估板文件test1拷贝至PC机"/home/embfly/"目录下。
Host# scp root@192.168.0.64:/test1 /home/embfly/
