Hi!

I am a beginner in all these embedded linux - mtd - jffs stuff. I am using Intel FLASH 28F320 (2 interleaved 16b chips of 8MB, so we have 32bit buswidth) (CFI) with TMS320C5471 platform. I turnd on MTD support, so I have 5 partitions: bootloader (/dev/mtd0), bootloader parameters (/dev/mtd1), kernel image (/dev/mtd2), ROMFS SDRAM image (/dev/mtd5), primary file system, which is romfs (/dev/mtd3) and I want the second to be jffs2 (/dev/mtd4):

c5471_init: CFI FLASH device size: 16384K

Creating 5 MTD partitions on "C5471 CFI":

0x00000000-0x000a0000 : "C5471 Bootloader"

0x000a0000-0x000c0000 : "C5471 Bootloader Parameters"

0x000c0000-0x001c0000 : "C5471 Kernel Image"

0x001c0000-0x00800000 : "C5471 Primary File System"

0x00800000-0x01000000 : "C5471 Secondary File System"

Creating 1 MTD partitions on "SDRAM":

0x00000000-0x006bffe0 : "SDRAM File System"


I have made jffs2 image:

arm-uclinux-mkjffs2 -d ./jffsfolder -l -e 0x00020000 -o jffs2.img >/dev/null

and I loaded it at addresses from 0x00800000, which correspond to fs2, i.e. /dev/mtd4.

When I try to mount jffs2:

# mount -t jffs2 /dev/mtd4 /mnt/ramdisk/tmp



it sends me messages:

jffs2: read_super for device 1f:04

and there it stops every time, with a few characters more or less. The situation was similar when I erased my flash before mounting the jffs2 (except it found completely empty flash). 



Have enyone an idea what I did wrong or what I missed to do? Could a problem be with that thread thing - thread_should_wake()?



Thank you in advance!

Iva
