* gemini: Fix up firmware checksum on DIR-685Linus Walleij2019-05-181-0/+1
| | | | | | | | | | | | | | | | | | Using the same method as the D-Link DAP-2695 A1 we use the "mtd" tool to augment the firmware checkum in flash on first boot of a new firmware on the D-Link DIR-685. We need to augment the Makefile for "mtd" to build in the special WRGG fixup support for Gemini as well. This works around the problem of the machine not booting after factory install unless the sysupgrade is applied immediately. Based on commit e3875350f3e4185020b64e0588bba521cd1d6e64 "ar71xx: add support for D-Link DAP-2695 rev. A1" Cc: Stijn Tintel <stijn@linux-ipv6.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* mtd: Make fixwrgg command work on DIR-685Linus Walleij2019-05-181-14/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The D-Link DIR-685 has the same problem as the D-Link DAP-2695: when flashing the factory image, the checksum includes the whole flashed image, even the rootfs_data part with the end of filesystem mark. Also the whole flashed image is stored in the flash, so on the first boot, the whole rootfs image is loaded into memory with the kernel. This is fixed using the fixwrgg command to mtd, but for this to work we need to make fixwrgg work with the Little-Endian ARM DIR-685. The code tries to be endian agnostic but this fails because the WRGG image loader doesn't. On ARM, the file size is stored in little endian format, and on big-endian systems it is stored in big endian format, so we can just drop all the friendly htonl() that will make the shdr->size big endian: this will actually break the little endian systems, and on the big endian systems the native endianness will still be correct. The magic number is always stored in little endian format however, so make sure this is always read in LE32 format. I chose to create a straight-forward le32_to_cpu() static inline that IMO is simple and easy to read. Cc: Stijn Tintel <stijn@linux-ipv6.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* mtd: base-files: Unify dual-firmware devices (Linksys)Jeff Kletsky2019-05-183-134/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consistently handle boot-count reset and upgrade across ipq40xx, ipq806x, kirkwood, mvebu Dual-firmware devices often utilize a specific MTD partition to record the number of times the boot loader has initiated boot. Most of these devices are NAND, typically with a 2k erase size. When this code was ported to the ipq40xx platform, the device in hand used NOR for this partition, with a 16-byte "record" size. As the implementation of `mtd resetbc` is by-platform, the hard-coded nature of this change prevented proper operation of a NAND-based device. * Unified the "NOR" variant with the rest of the Linksys variants * Added logging to indicate success and failure * Provided a meaningful return value for scripting * "Protected" the use of `mtd resetbc` in start-up scripts so that failure does not end the boot sequence * Moved Linksys-specific actions into common `/etc/init.d/bootcount` For upgrade, these devices need to determine which partition to flash, as well as set certain U-Boot envirnment variables to change the next boot to the newly flashed version. * Moved upgrade-related environment changes out of bootcount * Combined multiple flashes of environment into single one * Current-partition detection now handles absence of `boot_part` Runtime-tested: Linksys EA8300 Signed-off-by: Jeff Kletsky <git-commits@allycomm.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> [checkpatch.pl fixes, traded split strings for 80+ chars per line]
* mtd: add logic for TP-Link ramips recovery magicDavid Bauer2019-01-264-2/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | 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: add linksys_bootcount to the ipq40xx targetOever González2019-01-262-0/+116
| | | | | | | | | | | | This commit adds the object 'linksys_bootcount_fix.o' to the ipq40xx target. This is needed for the Linksys EA6350v3 device. Without this patch, the device will switch-back between the current and the last flashed firmware every 3 (three) reboots. With this patch, the device works as expected.

* mtd: improve check for TRX header being already fixedRafał Miłecki2018-07-151-7/+8
| | | | | | | | | | | First of all lengths should be compared after checking all blocks for being good/bad. It's because requested length may differ from a final one if there were some bad blocks. Secondly it makes sense to also compare crc32 since we already have a new one calculated. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
* mtd: support bad blocks within the mtd_fixtrx()Rafał Miłecki2018-07-151-6/+28
| | | | | | | | | | | | | | | | Reading MTD data with (p)read doesn't return any error when accessing bad block. As the result, with current code, CRC32 covers "data" stored in bad blocks. That behavior doesn't match CFE's one (bootloader simply skips bad blocks) and may result in: 1) Invalid CRC32 2) CFE refusing to boot firmware with a following error: Boot program checksum is invalid Fix that problem by checking every block before reading its content.

* mtd: add -c option for specifying amount of data to be used for checksumRafał Miłecki2016-05-093-12/+31
| | | | | | | | | | | | | | | 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.

* 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: detect image format when writingRafał Miłecki2016-02-063-13/+60
| | | | | | | | | | | | | | | 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
