erase block 단위로 정렬하면 좋다는데 그걸 어떻게 확인하지?
데이터시트 안보고 리눅스 레벨에서 확인할 순 없나?
| Try to align to eMMC erasure block size. It usually equals 0.5, 1, 2, 4, 8 MiB depending on eMMC datasheet. If you find block size alignment too much memory wasting, then stick to the page size, generally found in the range of 4..16 KiB. |
