    I'm currently trying to ubinize the ar71xx target, but I'm afraid I'll wipe the bootloader if I misconfigure UBI, so I'm kind of afraid to flash generated images . The patch (using trunk) is attached for anyone with a serial cable and more experience and confidence to review (please do) and test.

    fastmap support in ubinize? - narkive

    I hope Tanya is allowed to share her code soon such that I can review it. Adding fastmap to ubinize is not trivial as you can run into problems when your flash has bad blocks. i.e, If fastmap refers to PEB XY but PEB XY is bad. Then the flasher would have to be a) UBI aware and b) had to fixup the fastmap on-fly.--

    Mailing List Archive: UBI Fastmap updates

    (creating a fastmap on an image created by ubinize works now) - Fastmap is now able to reuse all PEBs if no empty PEBs are available - Minor fixes ... Sorry I couldn't review entirely, diff has gotten really enormous... I'll try to pick it up again when you'll get to the final merge submitting incremental patches.

    Creating and flashing UBI / UBIFS images - Bootlin's blog

    Next is the generation of the UBI image. The ubinize utility will need the Physical Erase Block size (PEB) (option -p) and the minimum I/O size (-m): # ubinize -vv -o -m -p KiB Your image is ready. You may now want to boot on the rootfs UBIFS partition. Keep on reading, then.

    [PATCH RFC] ubi-utils: Add a new utility ubidump

    Add a new ioctl to dump EC header and VID header to user space. This ioctl is called without lock so I think users *should not* run ubidump when volume is mounted.

    "UBI Fastmap is an optional feature which stores the physical to logical eraseblock relations in a checkpoint (called fastmap) to reduce the initialization time of UBI. The current init time of UBI is proportional to the number of physical erase blocks on the FLASH device. With fastmap enabled the scan time is limited to a fixed number of blocks."
