mtk-20170518/package/system/mtd/src/mtd.c, branch reboot MTK 20170518 : Mediatek SDK based on OpenWRT Barrier Breaker mtd: fix reading of image magic bytes in smaller chunks 2016-03-03T20:24:38+00:00 John Crispin john@openwrt.org 2016-03-03T20:24:38+00:00 4a4c324cd22e590990e323ed0ece974c7fa00d22 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 writing 2016-02-06T16:29:12+00:00 Rafał Miłecki zajec5@gmail.com 2016-02-06T16:29:12+00:00 b5c41ad28c31d61d6eb9a0c0f3550e75ea74e09f 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
