UBI provides +a flexible partitioning concept which still allows for wear-levelling +across the whole flash device. + +In a sense, UBI may be compared to the Logical Volume Manager +(LVM). Whereas LVM maps logical sector numbers to physical HDD sector +numbers, UBI maps logical eraseblocks to physical eraseblocks. + +More information may be found in the UBI design documentation: +ubidesign.pdf. Which can be found here: +http://www.linux-mtd.infradead.org/doc/ubi.html + +Partitioning/Re-partitioning + + An UBI volume occupies a certain number of erase blocks. This is + limited by a configured maximum volume size, which could also be + viewed as the partition size. Each individual UBI volume's size can + be changed independently of the other UBI volumes, provided that the + sum of all volume sizes doesn't exceed a certain limit. + + UBI supports dynamic volumes and static volumes. Static volumes are + read-only and their contents are protected by CRC check sums. + +Bad eraseblocks handling + + UBI transparently handles bad eraseblocks. When a physical + eraseblock becomes bad, it is substituted by a good physical + eraseblock, and the user does not even notice this. + +Scrubbing + + On a NAND flash bit flips can occur on any write operation, + sometimes also on read. If bit flips persist on the device, at first + they can still be corrected by ECC, but once they accumulate, + correction will become impossible. Thus it is best to actively scrub + the affected eraseblock, by first copying it to a free eraseblock + and then erasing the original. The UBI layer performs this type of + scrubbing under the covers, transparently to the UBI volume users. + +Erase Counts + + UBI maintains an erase count header per eraseblock. This frees + higher-level layers (like file systems) from doing this and allows + for centralized erase count management instead. The erase counts are + used by the wear-levelling algorithm in the UBI layer. The algorithm + itself is exchangeable. + +Booting from NAND + + For booting directly from NAND flash the hardware must at least be + capable of fetching and executing a small portion of the NAND + flash. Some NAND flash controllers have this kind of support. They + usually limit the window to a few kilobytes in erase block 0. This + "initial program loader" (IPL) must then contain sufficient logic to + load and execute the next boot phase. + + Due to bad eraseblocks, which may be randomly scattered over the + flash device, it is problematic to store the "secondary program + loader" (SPL) statically. Also, due to bit-flips it may become + corrupted over time. UBI allows to solve this problem gracefully by + storing the SPL in a small static UBI volume. + +UBI volumes vs. static partitions + + UBI volumes are still very similar to static MTD partitions: + + * both consist of eraseblocks (logical eraseblocks in case of UBI + volumes, and physical eraseblocks in case of static partitions; + * both support three basic operations - read, write, erase. + + But UBI volumes have the following advantages over traditional + static MTD partitions: + + * there are no eraseblock wear-leveling constraints in case of UBI + volumes, so the user should not care about this; + * there are no bit-flips and bad eraseblocks in case of UBI volumes. + + So, UBI volumes may be considered as flash devices with relaxed + restrictions. + +Where can it be found? + + Documentation, kernel code and applications can be found in the MTD + gits. + +What are the applications for? + + The applications help to create binary flash images for two + purposes: pfi files (partial flash images) for in-system update of + UBI volumes, and plain binary images, with or without OOB data in + case of NAND, for a manufacturing step. Furthermore some tools + are/and will be created that allow flash content analysis after a + system has crashed. + +Who did UBI? + + The original ideas, where UBI is based on, were developed by Andreas + Arnez, Frank Haverkamp and Thomas Gleixner. Josh W. Boyer and + some others were involved too. The implementation of the kernel + layer was done by Artem B. Bityutskiy. The user-space applications + and tools were written by Oliver Lohmann with contributions from + Frank Haverkamp, Andreas Arnez, and Artem. Joern Engel contributed a + patch which modifies JFFS2 so that it can be run on a UBI + volume. Thomas Gleixner did modifications to the NAND layer and also + some to JFFS2 to make it work. diff --git a/ubi-utils/old-utils/doc/unubi.roff b/ubi-utils/old-utils/doc/unubi.roff new file mode 100644 index 0000000..6cebc46 --- /dev/null +++ b/ubi-utils/old-utils/doc/unubi.roff @@ -0,0 +1,123 @@ +.TH UNUBI 1 "NOVEMBER 2006" FSP "FSP Flashutils" +.SH NAME +unubi \- extract volumes/eraseblocks from a raw\-UBI image +.SH SYNOPSIS +\fBunubi [\-aevEV] [\-d \fIout\-dir\fB] [\-r \fIvolume\-id\fB] +[\-b \fIblock\-size\fB] \fIimage\-file +.SH DESCRIPTION +.PP +\fBunubi\fR reads an image file containing blocks of UBI headers and data +(such as produced from \fBnand2bin\fR) and rebuilds the volumes within. +The default operation (when no flags are given) is to rebuild all valid +volumes found in the image. \fBunubi\fR can also read straight from the +onboard MTD device (ex. /dev/mtdblock/NAND). +.SH OPTIONS +.IP "\-a, \-\-analyze" +When flagged, analysis files are generated within the output directory. These +may include tables and or graphs detailing statistics gathered from the +eraseblock data. Files are prefixed `analysis_'. + +See \fBANALYSIS\fR. +.IP "\-b, \-\-blocksize \fIblock\-size\fR" +Specify in bytes the \fIimage\-file\fR eraseblock size. Sizes may be +postfixed with `KiB' or `MiB' to indicate mebibytes or kibibytes +respectively. Default is 128KiB. +.IP "\-d, \-\-dir \fIoutput\-dir\fR" +Specify the output directory. If no directory is specified, the default +is `unubi_\fIimage\-file\fR' within the curent working directory. If the +attempt to create the output directory fails, +.B unubi +will try to create it in /tmp before aborting. +.IP "\-e, \-\-eb\-split" +When flagged, images are created for each eraseblock in \fIimage\-file\fR +regardless of its validity. Each image is the complete eraseblock, including +headers and any space to the end of the eraseblock after where the data may +end. + +Invalid images are named `ebEEEE', where EEEE is the physical index of the +eraseblock in the image. Valid images are named `ebEEEE_VVV_NNN_RRR' where +VVV is the known volume ID, NNN is the logical number and RRR is the version +of the eraseblock data. Note that the version number is in hexadecimal. + +Invalid images may also contain this postfix, if the data in the header +could be valid (ie. the header contains a resonable volume ID, but the +header and/or data CRCs are not valid). If this is the case, images are named +`ebEEEE_VVV_NNN_RRR.reason', so as to distinguish known values from +non\-definite ones. + +See \fBREASON SUFFIXES\fR. +.IP "\-r, \-\-rebuild \fIvolume\-id\fR" +Specify a volume to rebuild. Can be used successively to specify +several volumes to be rebuilt. + +Images are named `volumeVVV' where VVV is the volume ID. For each missing +eraseblock, an error message will be printed. +.IP "\-v, \-\-vol\-split" +When flagged, images are created for each valid eraseblock in +\fIimage\-file\fR. Since a vaild eraseblock will have a defined data start and +data length, only this range will make up the image. + +Images are named `volVVV_NNN_RRR_EEEE', where, for the data in the eraseblock, +VVV is the volume ID, NNN is the logical number, RRR is the version and EEEE +is the phyisical index of the eraseblock in the image. +.IP "\-V, \-\-vol\-split!" +Same as above, only all images are the complete eraseblock (including headers, +and raw data, even past the point where the data is supposed to end). +Overrides \-v when both \-v and \-V are flagged. +.SH ANALYSIS +The following files will be generated during the analysis: +.IP "analysis_ec_hdr.data" +A space delimited table with these two columns for each eraseblock: the +eraseblock's index or physical position in the image, and the eraseblock's +erase count. The third column contains the erase count data sorted. +.IP "analysis_vid_hdr.data" +A space delimited table with these four colums for each eraseblock: the +volume ID, the volume logical number, the leb version, and the data size. +In addition there are a normalized column representing the volume ID and +volume logical number, a normalized column representing the leb version, and +a normalized column representing the data_size. These normalized columns are +used to better draw the the gnuplot image. +.IP "analysis_ec_hdr.plot" +A gnuplot script for quickly viewing a sample output from the respective .data +file. +.IP "analysis_vid_hdr.plot" +A gnuplot script for quickly viewing a sample output from the respective .data +file. +.SH REASONS SUFFIXES +When \-\-eb\-split produces possibly invalid, though usable, eraseblocks, the +known reason suffixes are: +.IP ".ec_magic" +The erase counter header did not contain a valid magic field. +.IP ".ec_hdr_crc" +The erase counter header did not contain a vaild header CRC field. +.IP ".vid_magic" +The volume ID header did not contain a valid magic field. +.IP ".vid_hdr_crc" +The volume ID header did not contain a valid header CRC field. +.IP ".data_crc" +The volume ID header did not contain a valid data CRC field. +.SH EXAMPLES +To extract and rebuild all valid volumes from demo.img (note the output +directory will be /home/user/unubi_demo.img): +.sp 1 +.RS +.B /home/user# unubi demo.img +.sp 1 +.RE +To analyze demo.img as well as extract and rebuild volume 7: +.sp 1 +.RS +.B /home/user# unubi \-a \-r 7 demo.img +.sp 1 +.RE +To split demo.img into raw images for each eraseblock into the folder +/var/eraseblocks: +.sp 1 +.RS +.B /home/user# unubi \-e \-d /var/eraseblocks demo.img +.SH AUTHORS +Frank Haverkamp +.sp 0 +Drake Dowsett +.SH CONTACT +Andreas Arnez diff --git a/ubi-utils/old-utils/inc/libubi.h b/ubi-utils/old-utils/inc/libubi.h new file mode 100644 index 0000000..82824bd --- /dev/null +++ b/ubi-utils/old-utils/inc/libubi.h @@ -0,0 +1,268 @@ +/* + * Copyright (c) International Business Machines Corp., 2006 + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
