CONFIG_MTD_MTDRAM=m CONFIG_MTD_BLOCK2MTD=m CONFIG_JFFS2_FS=m CONFIG_JFFS2_ZLIB=y CONFIG_JFFS2_LZO=y and other, which are already enabled for arm Can you give an example of the type of documentation you are trying to follow? https://wiki.maemo.org/Modifying_the_root_image http://wiki.emacinc.com/wiki/Mounting_JFFS2_Images_on_a_Linux_PC fedora has in mtd-utils jffs2reader, which should be able to list/dump content of file but not working on images with lzma compression I'm okay turning on JFFS2 but CONFIG_MTD_MTDRAM is listed as a test driver. I understand it's uses are limited but I'm not really excited about enabling it for all of Fedora. Created attachment 1305892 [details]
this is what i tested
(In reply to Laura Abbott from comment #5) > I'm okay turning on JFFS2 but CONFIG_MTD_MTDRAM is listed as a test driver. > I understand it's uses are limited but I'm not really excited about enabling > it for all of Fedora. there are three modules usable for simulating flash devices: nandsim for nand and block2mtd and mtdram for nor as most of toolchains for embedded platforms are for x86, i'm fine with enabling it only for x86, not all architectures like i did in patch what i tested so far is nandsim. block2mtd and mtdram i would like to test after vacation even i managed to use jffs2reader after endianess convertion using jffs2dump -e, it is tricky to dump dontent. with nandsim and jffs2 i was able to mount image and chroot to it just using qemu-mips-static within few seconds anything i can do to get enabled those modules? If the following set of options is sufficnet we can turn them on. CONFIG_MTD_BLOCK2MTD=m CONFIG_JFFS2_FS=m CONFIG_JFFS2_ZLIB=y CONFIG_JFFS2_LZO=y (In reply to Laura Abbott from comment #10) > If the following set of options is sufficnet we can turn them on. > > CONFIG_MTD_BLOCK2MTD=m > CONFIG_JFFS2_FS=m > CONFIG_JFFS2_ZLIB=y > CONFIG_JFFS2_LZO=y and CONFIG_JFFS2_COMPRESSION_OPTIONS it should be sufficient Sorry, I think this got lost with all the fall conferences. These are now on in rawhide. |
