FriendlyElec NanoPi R5S

最近入手了FriendlyElec NanoPi R5S

金属壳子和树莓派亚克力壳子一样大小.

m2 2208的 4T的ssd插进去只能识别用到2T容量

树莓派 vcgencmd 常用命令查看硬件状态

几个常用的命令:

1、查看时钟频率,可查看 arm, core, h264, isp, v3d, uart, pwm, emmc, pixel, vec, hdmi, dpi 的频率

vcgencmd measure_clock <clock>

例如:

pi@raspberrypi:~ $ vcgencmd measure_clock arm
frequency(45)=600000000
pi@raspberrypi:~ $ vcgencmd measure_clock core
frequency(1)=250000000

2、查看硬件电压,可查看core, sdram_c, sdram_p 的电压

vcgencmd measure_volts <id>

例如:

pi@raspberrypi:~ $ vcgencmd measure_volts core
volt=1.2000V
pi@raspberrypi:~ $ vcgencmd measure_volts sdram_c
volt=1.2500V

3、查看 BCM2835 Soc 温度

vcgencmd measure_temp
