是否可以通过安装cpufrequtils这种通用工具查询cpu频率
谢谢!

可以用$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq查看CPU频率。

也有。
By default, cpufreq, the cpufreq driver, and all of the standard governors are enabled with the ondemand governor selected as the default governor.

通过SD卡刷入ti-default-image和base-image,都没有看到有cpufreq
请问是系统没有起来吗?
