2007-11-24ubi-utils: unubi add physical erase block number for analysisFrank Haverkamp
The number is usefull to analyze cards with broken flash content. Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>
2007-11-24ubi-utils: various fixes in unubiFrank Haverkamp
The extraction of data from blocks used for dynamic volumes was totally broken. The data size was calculated wrong. This fix is not perfect, the alignment is still ignored. The parameter "header-size" is very misleading. It does not reflect the vid hdr offset properly. I assume therefor that it only works for the layout I am using where the vid hdr is at the _end_ of the 1st NAND page (2048). I added the generation of a textfile with information about the blocks which are going into the internal graph representation. Instead of a graph I think that a simple array will simplify the code very much. The array must than be sorted properly to cope with older and newer block-copies but that should not be a problem. discussed the tool with my coleage Andreas Arnez and we found that it might be a good idea to replace it even with a perl program for the same purpose since that would offer the flexibility to change it on the fly when needed. The tool is mainly used for crash analysis so it could be an advantage to change it without needing a C-compiler. Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>
2007-11-24ubi-utils: Update and bugfix unubiFrank Haverkamp
Drake Dawsett had done some changes to our unubi which where not yet published. I hereby send his latest code and integrated the parameter handling which was changed in our version. When reviewing this very huge patch we need to ensure that possible changes of others are not reversed. Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>
2006-11-06[MTD] UBI: rework of off-line UBI analysis toolDrake Dowsett
The new version can create a gnuplot graph of the erase count statistics. It can also extract UBI volumes and single blocks with a preanalysis of the EC as well as the VID header. It has a manual page too ;-). Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>
