UBI user-space tools, as well as other MTD user-space tools, are available from the the following git repository:
git://git.infradead.org/mtd-utils.git
Please, clone it and compile using make from the root mtd-utils directory. provides information about how to compile the whole mtd-utils repository tree. You should find the UBI tools under the ubi-utils sub-directory.
The repository contains the following UBI tools:
- ubinfo - provides information about UBI devices and volumes found in the system;
- ubiattach - attaches MTD devices (which describe raw flash) to UBI and creates corresponding UBI devices;
- ubidetach - detaches MTD devices from UBI devices (the opposite to what ubiattach does);
- ubimkvol - creates UBI volumes on UBI devices;
- ubirmvol - removes UBI volumes from UBI devices;
- ubiupdatevol - updates UBI volumes; this tool uses the which leaves the volume in "corrupted" state if the update was interrupted; additionally, this tool may be used to wipe out UBI volumes;
- ubicrc32 - calculates CRC-32 checksum of a file with the same initial seed as UBI would use;
- ubinize - generates UBI images;
- ubiformat - formats empty flash, erases flash and preserves erase counters, flashes UBI images to MTD devices;
- mtdinfo - reports information about MTD devices found in the system.
All UBI tools support "-h" option and print sufficient usage information.
Note, the ubiattach and ubidetach tools won't work if the kernel version is less than 2.6.25, because corresponding UBI features did not exist in the older kernels.
