硬件： QCA9531_16M+128M_QSDK+OpenWRT 

 

1.查看Flash容量大小(存儲空間,可以理解為電腦的硬盤)
root@OpenWrt:/# dmesg |grep spi |grep Kbytes #查看Flash容量
[ 0.700000] m25p80 spi0.0: w25q128 (16384 Kbytes)
root@OpenWrt:/#

2.查看RAM容量大小（可以理解為電腦的內存條）
root@OpenWrt:/# cat /proc/meminfo |grep MemTotal #查看RAM大小
MemTotal: 126340 kB
root@OpenWrt:/#
root@OpenWrt:/# free -h |grep Mem | awk -F ' ' '{print $2}' #查看RAM大小 (單位kB)
61348
root@OpenWrt:/#
root@OpenWrt:/# free -h |grep Mem | awk -F ' ' '{print $3}' #已使用的RAM大小(單位kB)
23788
root@OpenWrt:/#
root@OpenWrt:/# free -h |grep Mem | awk -F ' ' '{print $4}' #空閑可用的RAM大小(單位kB)
35376
root@OpenWrt:/#

3.CPU內存主頻型號
root@OpenWrt:/# dmesg |grep Clocks |awk -F ' ' '{print $4}' #查看CPU主頻
CPU:650.000MHz,
root@OpenWrt:/#
root@OpenWrt:/# dmesg |grep Clocks |awk -F ',' '{print $2}' #查看內存主頻
DDR:597.485MHz
root@OpenWrt:/#
root@OpenWrt:/# cat /proc/cpuinfo |grep 'system type' #查看系統類型
system type : Qualcomm Atheros QCA9531 rev 2
root@OpenWrt:/#
root@OpenWrt:/# cat /proc/cpuinfo |grep 'cpu model' #查看CPU型號
cpu model : MIPS 24Kc V7.4
root@OpenWrt:/#
root@OpenWrt:/# cat /proc/cpuinfo |grep 'machine' #查看設備型號
machine : Qualcomm Atheros AP147 reference board
root@OpenWrt:/#
