Emmc lifetime Jetson TX2


We have some TX2 modules with eMMC lifetime estimation that is worrying:

nvidia@tegra:~$ sudo mmc extcsd read /dev/mmcblk0 | grep LIFE
eMMC Life Time Estimation A [EXT_CSD_DEVICE_LIFE_TIME_EST_TYP_A]: 0x02
eMMC Life Time Estimation B [EXT_CSD_DEVICE_LIFE_TIME_EST_TYP_B]: 0x0b

Could you provide more details about the Toshiba THGBMFG8C4LBAIR emmc module?
We can’t find its datasheet.
What is the estimated number of read/write cycles?
How can we know the number of spare-blocks still available?

Thank you.

Kind regards,


We can’t provide such info. Please check with vendor directly.
