2015-11-11mtd-utils: Restructure the mtd-utils source.Dongsheng Yang
* There is no code modification in this commit, only moving * the files to proper place. The user tools looks a little messy as we place almost the all tools in the root directory of mtd-utils. To make it more clear, I propose to introduce the following structure for our source code. mtd-utils/ |-- lib |-- include |-- misc-utils |-- jffsX-utils |-- nand-utils |-- nor-utils |-- ubi-utils |-- ubifs-utils `-- tests Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2015-11-11nandtest: support hex/dec/oct for --offset and --lengthBrian Norris
These two options are handled inconsistently, which caused an unnecessary amount of head scratching. Let's just use the simple helpers too, so we get the error handling right. Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2014-09-08nandtest: fix --reads argumentGuido Martínez
The --reads option specifies the argument as optional, but doesn't check for a null optarg, which means that nandtest segfaults when run as "nandtest --reads". Fix this by making the argument required, and changing the help text to not specify it as optional. Argument -r already specifies the argument as required, so we fix this inconsistency too.

2014-05-30nandtest: Introduce multiple reads & check iterationsEzequiel García
The current nandtest performs a simple test which consists of: 1. erase block 2. write data 3. read and verify In order to improve the nandtest strength, this commit adds a new parameter to increase the number of "read and verify" iterations. In other words, the test now consists of: 1. erase block 2. write data 3. read and verify (N times) This seem to apply more pressure on a NAND driver's ECC engine and has been used to discover stability problems with an old OMAP2.

2014-05-05nandtest: Move the "read and compare" code to a functionEzequiel Garcia
This commit makes no functionality change, and simply moves the read and compare code into a separate read_and_compare() function. Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2014-05-05nandtest: Remove redundant checkEzequiel Garcia
This commit removes a redundant 'len' check, which is already performed just after the pread call. Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2013-07-01nand{dump, test, write}: clean up --help handlingMike Frysinger
We should send the output to stdout when the user passes -h/--help and then exit(0), but otherwise the output should go to stderr and then exit(1). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2013-07-01move _GNU_SOURCE to the main makefileMike Frysinger
A bunch of utils are relying on _GNU_SOURCE already. The new prompt code uses getline() which is now part of POSIX, but in older versions of glibc, it was behind _GNU_SOURCE as it was a GNU extension. This change doesn't actually tie us to glibc. Only code that uses GNU extensions does that. It just kills warning when using older versions of glibc.

2011-12-05nandtest: seed random generator with timeBrian Norris
If a seed is not provided via --seed, we use the default rand() values, which produces the same sequence of values every run. Since this is undesirable, we should choose a random seed via the current time(). Note that this patch moves the srand() until after all the initial options processing.

2011-08-25nandtest: print number of bits corrected during testBen Gardiner
The nandtest program monitors the corrected ecc stat to determine if an ECC correction has taken place during the last write-read. If so, it prints "ECC corrected". The mtd subsytem will store the number of bits corrected in the corrected ecc stat so update the nandtest output to print also the number of bits corrected when performing the test.
