查看eMMC寿命

var="$(cat /sys/kernel/debug/mmc0/mmc0\:0001/ext_csd)"
eol=${var:534:2};slc=${var:536:2};mlc=${var:538:2}
echo "EOL:0x$eol SLC:0x$slc MLC:0x$mlc"

#EOL是状态  SLC/MLC是使用过的寿命

或者

cat /sys/class/mmc_host/mmc0/mmc0\:0001/life_time

cat /sys/class/mmc_host/mmc2/mmc2\:0001/life_time

网上买的矿渣

亚瑟256G矿渣(人家跑了17万分)，发给日大改1G内存,传回来的eMMC情况如下.

0x01代表正常，0x08 代表老年人了，电量仅剩余20%
