Input/Output |
Type |
Description |
|---|---|---|---|
card_id |
Input |

flash_index |
Input |
unsigned int |
Flash index. |
pflash_info |
Output |
dm_flash_info_stru * |
Flash information. The flash information struct is as follows: struct dm_flash_info_stru { unsigned long flash_id; /* combined device & manufacturer code */ unsigned short device_id; /* device id */ unsigned short vendor; /* the primary vendor id */ unsigned int state; /*flash health*/ unsigned long size; /* total size in bytes */ unsigned int sector_count; /* number of erase units */ unsigned short manufacturer_id; /* manufacturer id */ } |
