mNAND Health and Status Utility (mnand_hs)

The mNAND Health and Status utility, mnand_hs, prints the health and status of onboard eMMC and UFS in Linux.

Note

Some options are vendor specific. Consequently, some options are valid for Hynix while other eMMC devices report errors. For example, mnand_hs -ah displays age per block for Hynix. However, for a Samsung device or Toshiba device the same option reports a “block data not available” error.
