| This option enables UBI debugging messages. | |
| config MTD_UBI_DEBUG_PARANOID | |
| bool "Extra self-checks" | |
| default n | |
| depends on MTD_UBI_DEBUG | |
| help | |
| This option enables extra checks in UBI code. Note this slows UBI down | |
| significantly. | |

| instead. This option enables this capability - it is very useful for | |
| debugging and testing. | |

| bool "Emulate flash write failures" | |
| depends on MTD_UBI_DEBUG | |
| default n | |

| bool "Emulate flash erase failures" | |
| depends on MTD_UBI_DEBUG | |
| default n | |
