Method 1 (for most movement):
see after the system starts EMMC endurance, serial printer information input command is as follows:
tclsu (or SU)
CAT / SYS / Kernel / Debug / mmc0 / mmc0: 0001 / the EXT_CSD
Run after a long series of numbers will appear, these digital copy into a text document, a text editor such as UltraEdit open and view the first 537-538 digits / letters (i.e. 268byte), behind the cursor as shown in FIG. 2 digits.
For this figure is explained below 2,01-0A normal range, other values are not normal.
a) If this value is 00, it means that the movement does not support this method to query EMMC endurance;
b) If this value is 0B, it is erasing times Fengyun EMMC has exceeded the maximum number of erasure. This situation EMMC unstable state, the initial state is generally still stuck in the boot Logo, can often be forced to boot after the upgrade, but with a short period of time, the state will become Logo card again.
This value is only a percentage, the number is not clear. 0x01 indication e.g. 0% --10% Life, and so on.
Method 2 (for Mstar movement):
hold down the Enter key on the computer boot, mboot, enter, and then enter the command mmc ecsd, and then view ecsd [268] value, e.g. ecsd [268]: 0x1, represents endurance less than 10%.
Numerical methods and 1 2 is the same seen. Just not start to turn the deck plate, the more practical.
