测试指令

播放音频:aplay aigei.wav

=========================================================================

测试时间:

查看系统时间:date

设置时间:date -s "2023-09-21 16:00:00"

设置芯片时间:hwclock -w

查看芯片时间:hwclock

=========================================================================

测试背光:

echo 0 > sys/class/backlight/backlight/brightness

echo 50 > sys/class/backlight/backlight/brightness

echo 100 > sys/class/backlight/backlight/brightness

可以明显看到亮度变化

=========================================================================

测试SD卡:

df -h

=========================================================================

读写速度测试:

查看占用内存大小:df -h
读速度:hdparm -t /dev/mmcblk2
写速度:time dd if=/dev/zero of=/userdata/test bs=1024k count=50 cnotallow=fdatasync

=========================================================================

测试ADC按键

cat sys/bus/iio/devices/iio\:device0/in_voltage0_raw

读取AD0,然后下面是三个按键的AD值

=========================================================================

CPU温度

cat /sys/class/thermal/thermal_zone0/temp

cat /sys/class/thermal/thermal_zone1/temp

CPU频率

cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq //查看当前运行CPU频率cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq //查看软件上最后一次设置的CPU频率cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies //查看支持的CPU频率echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor //使能CPU性能模式，跑最高频echo userspace > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor //切换governor到userspaceecho 1008000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed //设置CPU频率 需要先切换到userspaceecho 1512000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_setspeed //设置CPU频率 需要先切换到userspace
