全志平台Tina系统spi存储设备和SDCARD读写测试的方法

spi 读写测试：

写：dd if=/dev/urandom of=/mnt/UDISK/dd.tmp conv=fsync

读：dd if=/mnt/UDISK/dd.tmp of=/dev/null

tf卡读写：

需要先插入TF卡，设备会自动检测并生成节点

写：dd if=/dev/urandom of=/mnt/SDCARD/dd.tmp bs=1M count=10M conv=fsync

清内存：echo 3 > /proc/sys/vm/drop_caches

读：dd if=/mnt/SDCARD/dd.tmp of=/dev/null bs=1M count=10M

(这句如果提示dd: can't open 'id=/mnt/SDCARD/dd.tmp': No such file or directory，可能是因为复制的内容里有乱码，手动输入试试)

 

tinatest测试方法：

编译固件的时候make menuconfig把tinatest选上，并配置相应的存储测试

spi 读写测试：tt /base/storage/rwdev

tfcard读写测试：

修改/etc/tinatest.json下的读写路径参数devfile，改成/mnt/SDCARD/xxx

tt /base/storage/rwdev

 

跑测试时候的log：

root@TinaLinux:/# tt /base/storage/rwdev
