mtd-utils: Restructure the mtd-utils source.

2015-11-11T22:38:40+00:00

* 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 Signed-off-by: Brian Norris

nandtest: support hex/dec/oct for --offset and --length

2015-11-11T22:05:07+00:00

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

nandtest: fix --reads argument

2014-09-08T10:29:32+00:00

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.

nandtest: Introduce multiple reads & check iterations

2014-05-30T23:35:07+00:00

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.

nandtest: Move the "read and compare" code to a function

2014-05-05T07:32:33+00:00

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 Signed-off-by: Artem Bityutskiy

nandtest: Remove redundant check

2014-05-05T07:31:04+00:00

This commit removes a redundant 'len' check, which is already performed just after the pread call. Signed-off-by: Ezequiel Garcia Signed-off-by: Artem Bityutskiy

nand{dump, test, write}: clean up --help handling

2013-07-01T06:00:32+00:00

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 Signed-off-by: Artem Bityutskiy

move _GNU_SOURCE to the main makefile

2013-07-01T05:55:49+00:00

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. Signed-off-by: Mike Frysinger Signed-off-by: Artem Bityutskiy

nandtest: seed random generator with time

2011-12-05T06:27:31+00:00

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.

nandtest: use seed argument

2011-12-01T07:55:05+00:00

if a seed is provided it is actually not used. First call is "seed = rand()" killing the given seed. Signed-off-by: Jan Weitzel Tested-by: Brian Norris Signed-off-by: Artem Bityutskiy
