A Dmmc-dev-attrs.rst35 preferred_erase_size Preferred erase size
47 "erase_size" is the minimum size, in bytes, of an erase
48 operation. For MMC, "erase_size" is the erase group size
58 1. A single erase command will make all other I/O on
62 duration of the erase - which could be a several
64 2. To be able to inform the user of erase progress.
65 3. The erase timeout becomes too large to be very
66 useful. Because the erase timeout contains a margin
67 which is multiplied by the size of the erase area,
71 "erase_size" is not the most efficient unit to erase
