openwrt查看flash、RAM、CPU信息

1.查看Flash容量大小(存储空间,可以理解为电脑的硬盘)

[email?protected]OpenWrt:/# dmesg |grep spi |grep Kbytes? #查看Flash容量
[??? 0.660000] m25p80 spi0.0: mx25l12805d (16384 Kbytes)
#16384/1024=16M 既是16M的Flash

2.查看RAM容量大小（可以理解为电脑的内存条）

[email?protected]:/# cat /proc/meminfo |grep MemTotal?? #查看RAM大小
MemTotal:????????? 61348 kB

[email?protected]:/# free -h |grep Mem | awk -F ‘ ‘ ‘{print $2}‘? #查看RAM大小 (单位kB)
61348

[email?protected]:/# free -h |grep Mem | awk -F ‘ ‘ ‘{print $3}‘ #已使用的RAM大小(单位kB)
23788

[email?protected]:/# free -h |grep Mem | awk -F ‘ ‘ ‘{print $4}‘ #空闲可用的RAM大小(单位kB)
35376

3.CPU内存主频型号信

[email?protected]:/# dmesg |grep Clocks |awk -F ‘ ‘ ‘{print $4}‘? #查看CPU主频
CPU:650.000MHz,

[email?protected]:/# dmesg |grep Clocks |awk -F ‘,‘ ‘{print $2}‘ #查看内存主频
DDR:421.997MHz

[email?protected]:/# cat /proc/cpuinfo |grep ‘system type‘? #查看系统类型
system type???????????? : Qualcomm Atheros QCA9533 rev 1

[email?protected]:/# cat /proc/cpuinfo |grep ‘cpu model‘? #查看CPU型号
cpu model?????????????? : MIPS 24Kc V7.4

[email?protected]:/# cat /proc/cpuinfo |grep ‘machine‘?? #查看设备型号machine???????????????? : TP-LINK TL-WR841N/ND v9
