mtd-utils.git/nandwrite.c, branch v2.3.1

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

nandwrite: amendment to Mike's --input-* series

2013-07-01T06:12:43+00:00

This is a delta between v1 and v2 of the patches. I pushed v1 instead of picking v2, and this is a fixup. Signed-off-by: Artem Bityutskiy

nandwrite: add --input-{skip,size} options

2013-07-01T06:00:49+00:00

If you have a file image and want to copy sub-portions out and into NAND, there's no easy way to do that. You can use dd to extract it to a temp file, or pipe it to nandwrite 1 page at a time. Both suck. Add two new flags to explicitly set the size and offset of the input file. Seeking stdin isn't currently supported as I'm not sure it's necessary. It wouldn't be hard to add though...

nandwrite: clean up length types

2013-07-01T06:00:41+00:00

We use 'int' in many places to represent offsets/sizes. That obviously does not play well with larger NAND devices on 32bit systems. Instead, use the right type as needed: - long long to represent the length of the image - use fstat() rather than lseek();lseek(); to get the length of the image - use size_t/ssize_t when working with read() - tweak the printf formats as needed Signed-off-by: Mike Frysinger 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

mtd-utils: Check mtdoffset is not larger than mtd.size in case of a bad block.

2012-06-29T08:29:26+00:00

mtdoffset is being tested against mtd.size in the outer two loops, but the third nested one does not test against it. In case of a bad block we'll try to access an out of bounds offset in the next MEMGETBADBLOCK ioctl, which will fail with EINVAL. In case mtdoffset is indeed larger than the partition size, we need to bail, since there are not enough "good" blocks to complete the write.

nandwrite: minor cleanups

2012-06-29T07:21:41+00:00

Remove extra brackets and some style changes to make it more readable for a person who deals mostly with the kernel code. Signed-off-by: Artem Bityutskiy

nandwrite: use common.h "errmsg" functions

2011-09-11T13:11:41+00:00

Convert several forms of exit(), perror(), etc. to use common.h helper functions. Also, move one of our parameter checks inside the process_options() function for consistency. Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy

nandwrite: re-implement `--autoplace' option

2011-09-11T13:11:41+00:00

The restructuring of mtd_write() has allowed us to use `--autoplace' somewhat successfully; it is supported by the new ioctl(MEMWRITE) as well as some legacy code utilizing the deprecated ioctl(MEMGETOOBSEL). Signed-off-by: Brian Norris Signed-off-by: Artem Bityutskiy
