nandwrite: warn about writing 0xff blocks

2022-03-28T06:49:40+00:00

Such blocks may be incorrectly treated as empty (even though they may have non-erase OOB). Warn about it so people may start useing --skip-all-ffs . Signed-off-by: Rafał Miłecki Signed-off-by: David Oberhollenzer

mtd-utils: Fix potential negative arguments passed to close(2)

2020-02-09T21:13:18+00:00

Many tools open a file descriptor, close it a the end and have some form of error path in between that jumps to the end. In some cases, if opening the file fails the error path is taken and the utility ends up closing one or more invalid file descriptors. It's technically not a real issue but something that pretty much any static analysis tool barks at. Signed-off-by: David Oberhollenzer

nandwrite: Add --skip-bad-blocks-to-start option

2017-01-18T13:42:10+00:00

The --skip-bad-blocks-to-start option will increase the seek offset by the size of each bad block encountered between the start of the partition and the specified start address. This can be useful when writing part way through a partition that will be read using a simple bad-block-skipping algorithm. Signed-off-by: Mike Crowe Signed-off-by: David Oberhollenzer

nandwrite: fix/cleanup bad block skipping

2017-01-12T10:02:19+00:00

JFFS2 supports clustering erase blocks to virtual erase blocks. nandwrite supports this, but previously mixed up virtual and physical erase block numbers when checking for bad blocks. This patch adds a function for checking if a virtual erase block is bad and replaces the broken mtd_is_bad loop. Signed-off-by: David Oberhollenzer

nandwrite: replace erase loop with mtd_erase_multi

nandwrite: add stricter sanity checking for blockalign

2017-01-12T10:02:18+00:00

This patch makes sure that a virtual erase block is always composed of a postivie number of erase blocks (i.e. 1 or more) and enforces the block alignment to be a power of two as suggested by the help text and assumed throughout the program. Signed-off-by: David Oberhollenzer

nandwrite: Factor out buffer checking code

Pull the buffer content checking code into separate function and simplify the code invoking it slightly. Signed-off-by: Marek Vasut Reviewed-by: Boris Brezillon Signed-off-by: David Oberhollenzer

Unify version string printing

2016-11-17T10:36:55+00:00

When a program does sophisticated enough command line processing (i.e. getopt), make sure it responds to -V and --version. When a program prints a version string, make sure it uses the common_print_version macro to print out its name, that it is part of mtd-utils and the mtd-utils version from the build system in a fashion similar to common program packages like the GNU coreutils. When a program responds to -V/--version or -h/--help, make sure it reports success exit status. Signed-off-by: David Oberhollenzer Signed-off-by: Richard Weinberger
