jffs2 issues
Hi all,
i am looking for some help on an issue with jffs2: i can create jffs2 fs, mount, store edit/write some files, unmount, but in a next mount i find no more files/dirs. MTD probe detect correctly my flash, the chip have erase sectors of 4KB, or blocks of 64KB. MTD shows correctly a 0x1000 erase size. / # / # cat /proc/mtd dev: size erasesize name mtd0: 00010000 00001000 "Colilo (64K)" mtd1: 002f0000 00001000 "Kernel+ROMfs (3008K)" mtd2: 00100000 00001000 "JFFS2 (1024K)" <--- want to use this partition only as jffs2 to store non volatile data mtd3: 0009d000 00001000 "ROMfs" So from uClinux, i try to prepare the jffs2 fs: # eraseall /dev/mtd2 erased 1024 Kibyte @ 0 -- 100% complete. cat /dev/mtd2 i see the flash has been cleared then i create a folder "backup" in /var with some files and try to crete the jffs2 fs: mkfs.jffs2 -d backup -o jffs2.img cp /dev/mtd2 jffs2.img Then i just mount/umount the device, but i get often the issue described, remounting, no files. Writing files is also notice some MTD debug trace, maybe an error: Node totlen on flash (0xffffffff) != totlen from node ref (0x00000074) Any help is really appreciated. many thanks angelo |
