【新人上手】D1哪吒开发板Tina Linux下查看系统内存和测试存储器件读写速率
-
7、查看当前系统内存
查看内存指令：
系统优化满足运行内存≤32MB
echo 3 > /proc/sys/vm/drop_caches; free可以看到
root@TinaLinux:/# echo 3 > /proc/sys/vm/drop_caches; [ 1130.933910] ash (138): drop_caches: 3 root@TinaLinux:/# free total used free shared buffers cached Mem: 1021656 37612 984044 36 548 4204 -/+ buffers/cache: 32860 988796 Swap: 0 0 08、查看储存情况
SPI-Nand大小查看，方式一：
cat /proc/partitions可见
root@TinaLinux:/# cat /proc/partitions major minor #blocks name 31 0 1024 mtdblock0 31 1 4096 mtdblock1 31 2 1024 mtdblock2 31 3 256000 mtdblock3 254 0 20412 ubiblock0_5以上所有相加即为262144KB=256M。
方式二：启动log中已经包含
[ 1.425770] sunxi-spinand-phy: TotalSize: 256 M9、SPI-Nand顺序写
SPI-Nand顺序写：>=2MB/s(四线)。

支持最大128G TF卡，支持热拔插，提供命令查看储存情况。
插了卡的情况下执行：
cat /proc/partitions结果如下：
root@TinaLinux:/# cat /proc/partitions major minor #blocks name 31 0 1024 mtdblock0 31 1 4096 mtdblock1 31 2 1024 mtdblock2 31 3 256000 mtdblock3 254 0 20412 ubiblock0_5 179 0 31205376 mmcblk0 179 1 4032 mmcblk0p1 179 2 252 mmcblk0p2 179 3 252 mmcblk0p3 179 4 10332 mmcblk0p4 179 5 20412 mmcblk0p5 179 6 504 mmcblk0p6 179 7 14112 mmcblk0p7 259 0 31133724 mmcblk0p8取mmcblk0前的数字，例如31205376 KB,换算得31.1G，往上取整，即为32G卡。
