2010-09-12nanddump: drop unused --ignoreerrors optionMike Frysinger
Nowhere in the nanddump code is the "ignoreerrors" variable used. So drop the option completely. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-08-30nanddump: Fix hexdump nybble orderingJon Povey
Hex dumps were being printed with the nybbles reversed since commit 6ff458433ba15b8a7cb258ce64e64e98982df26e Fix. Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk> CC: Brian Norris <norris@broadcom.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-21nanddump: add "forcebinary" flagBrian Norris
Restrict binary dumping so that by default, binary garbage is not printed directly to a terminal. Output redicted to files or piped to other commands should not be affected (as judged by "isatty(ofd)"). A new flag "-a" or "--forcebinary" is included so that users can override this behavior if necessary.

2010-07-21nanddump: add canonical (hex+ascii) flagBrian Norris
Added the "-c" or "--canonicalprint" flag (modelled off 'hexdump -C') so that users can choose to print ASCII output next to the prettyprint output. This is really an extension to the prettyprint option, so the two options do not conflict if they are both included in the same execution.

2010-07-21nanddump: robust pretty hexdumpBrian Norris
Adapted code from the linux kernel hex_dump_to_buffer() (lib/hexdump.c) to provide a more robust hexdump for the pretty option. Now, nanddump can print out any size of OOB (or page for that matter...) without having to worry about non-multiples of 16. This also provides ability to dump ASCII format next to the hex output once additional command-line flags are added. Tested with Samsung K9GAG08U0D Signed-off-by: Brian Norris <norris@broadcom.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-07-18nanddump: increase max OOB sizeBrian Norris
Supported OOB and page sizes can now be changed more easily by a macro constant. NAND_MAX_OOBSIZE needed increased to support 218 and 224 byte OOB. Signed-off-by: Brian Norris <norris@broadcom.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-06-12mtd-utils: support 4096+64 page sizesEnric Balletbo i Serra
Add support for oobsize 64 and writesize 4096 in nanddump & nandwrite. Artem: some more info from further e-mail exchange: > Are there flashes with the 4096 page / 64 spare combination? Could you > refer to one? May be any URL? I thought 4096 comes with 128. Much to my regret I can't provide a URL because is not public. IGEP v2 board has a Onenand with two dice of 2048/64 spare combination but mtd views 4096/64. The minimal write page is 4K (2K from first dice and 2K from second dice).

2007-08-03Remove $Id:$ tagsJosh Boyer
The $Id:$ tags are left over from the old CVS repository. Several files have since been changed, and they generally have little value in a git repo so they should be removed. Signed-off-by: Josh Boyer <jwboyer@gmail.com>
2007-03-15MTD-Utils: fix handling of ioctl return value in nand-utilsFrank Haverkamp
Older kernel do not implement the MTDFILEMODE ioctl. In this case nandwrite and nanddump should have used MEMGETOOBSEL in combination with MEMSETOOBSEL. Unfortunately the return value of the unsucessfull ioctl is not -ENOTTY, but -1 and errno contains ENOTTY. This change fixes this issue. I have not tested all cornercases. Would be good if someone could do more careful testing than I did, or maybe reviewing is sufficient in this case.

2006-05-30Update mtd-abi.h and use new NAND ECC functionalityThomas Gleixner
The NAND rework exposes more information to userspace and has a different mechanism to read raw FLASH contents without ECC. Update nanddump and nandwrite.
