UMS512如何使用ADB修改DDR运行频率
UMS512如何使用ADB修改DDR运行频率
adb root
adb remount
adb shell
cd /sys/class/devfreq/scene-frequency/sprd-governor
或者cd /sys/class/devfreq/scene-frequency/sprd_governor
cat ddrinfo_freq_table 查看当前支持的DDR频率,例如256 384 512 768 1024 1333 1536 1866
echo xxx > scaling_force_ddr_freq 固定DDR频率，
比如固定DDR频率为1024Mhz：echo 1024 > scaling_force_ddr_freq
cat ddrinfo_cur_freq 查看当前DDR频率
