* mtd: add CRC signature to RedBoot partition mapDaniel Gimpelevich2019-07-171-0/+21
| | | | | | | | | | The code for calculating the CRC32 signatures for RedBoot FIS partitions was already included, but for unknown reasons, it was never invoked. Some bootloaders enforce checking these for loaded kernels, so they should be written. This patch does so.

* mtd: add logic for TP-Link ramips recovery magicDavid Bauer2019-01-261-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds an option to set the recovery flag of newer TP-Link MediaTek boards and remove it after a successful write. To make use of this feature, add the '-t' option to mtd-write. The '-t' option takes the mtd partition containing the recovery flag (usually 'romfile') as an argument. Make sure this partition is not flagged as read-only! Example: > mtd -t romfile write owrt.bin firmware This command writes the recovery-flag before it begins writing the image to the firmware partition. After the image-write has been successful, the recovery flag is removed. This way, the TP-Link web-recovery is automatically enabled on an unsucessful flash (e.g. power loss). This option is only available if the mtd package is compiled for the ramips target. Signed-off-by: David Bauer <mail@david-bauer.net>
* mtd: fix erase handling with partition offset on writeFelix Fietkau2018-04-201-1/+1
| | | | | | | | When a partition offset is given, it is used in an lseek call, which affects write, but not erase. Add it to the offset for erase calls as well Signed-off-by: Felix Fietkau <nbd@nbd.name>

* mtd: add -c option for specifying amount of data to be used for checksumRafał Miłecki2016-05-091-3/+13
| | | | | | | | | | | | | | | So far fixtrx was calculating checksum over amount of data matching partition erase size. It was mostly a workaround of checksum problem after changing anything in initial TRX content (e.g. formatting JFFS2). Its main purpose was to make bootloader accept modified TRX. This didn't provide much protection of flash data against corruption. This new option lets caller request calculating checksum over a bigger amount of data. It may be used e.g. to include whole kernel data for checksum and hopefully make bootloader go info failsafe mode if something goes wrong. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>
* mtd: add missing breaks in a switchrmilecki2016-05-091-0/+2

* mtd: fix reading of image magic bytes in smaller chunksJohn Crispin2016-03-031-5/+12
| | | | | | | | | | | | | | | The image_check currently fails when it cannot read all magic bytes in a single chunk. But this can happen when the data are read from a pipe. This currently breaks the openmesh.sh upgrade script with musl because it uses dd with a blocksize of 1 to copy the image file to the mtd process. The read can simply be repeated until enough bytes are read for the magic byte check. It only stops when either an error was returned or 0 bytes were read.

* mtd: fix Seama format after replacing EOF with sysupgrade dataRafał Miłecki2016-02-101-2/+13
| | | | | | | | | | Seama header has MD5 similarly to TRX and its CRC32. We need to update it after replacing anything in Seama entity content to make bootloader accept it. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48688
* mtd: detect image format when writingRafał Miłecki2016-02-061-3/+54
| | | | | | | | | | | | | | | Recently TRX checking code was changed to detect Seama format and don't abort whole writing operation because of it. This isn't a good long-term solution. It's a poor idea to teach every format handler recognizing all possible formats. Instead it should be handled in a generic code which should run check depending on the detected format. This will also allow further improvements like fixing formats other than TRX after replacing JFFS2. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 48639
* mvebu: add support for the Linksys boot counterImre Kaloz2015-08-191-0/+12

* mtd: fix md5sum error checkingJohn Crispin2015-03-051-1/+1
| | | | | | | | | | | | | | In mtd_verify(), the return value of md5sum() has been interpreted as error if nonzero, while the function returns number of processed bytes, which caused mtd_verify() to always fail. This patch fixes error checking to interpret only negative values as errors. Signed-off-by: Zefir Kurtisi <zefir.kurtisi@neratec.com> SVN-Revision: 44605

* mtd: add support for bad blocks in NAND flashFelix Fietkau2014-03-261-5/+46
| | | | | | | | | | | | | NAND flash is very likely to contain bad blocks. Currently, mtd and therefore sysupgrade fails when it encounters a single bad block, potentially leaving an unbootable system. This patch allows the mtd utility to skip bad blocks in NAND flash and complete sysupgrade successfully.

* ar71xx: Unifi AP Pro sysupgrade patchFelix Fietkau2013-11-141-3/+12
| | | | | | | | | | | | | | | | | | The current implementation of mtd will not append the backup file created by sysupgrade to the correct partition, as mtd will append the data to first jffs2 partition it finds. As the kernel is also stored on a jffs2 partition (which resides before the overlay partition), the data will be appended to this partition. To fix this problem, a new option -s <number> skip the first n bytes when appending data to the jffs2 partiton, defaults to "0" is added to mtd.
