Hello
I'm working with TCM-BF537 from bluetechnix and 2009-R1-RC6...
I had a problem with the filesystem of MMC card.
I make two partiticions using fdisk /dec/mmcblk0
I can format to ext2 filesystem and mount using
mke2fs -c /dev/mmcblk0p1;
mount /dev/mmcblk0p1 /mntP1
The problem is when I try to format to ext3 filesystem
root:/dev> mke2fs -c /dev/mmcblk0p1
mke2fs 1.41.4 (27-Jan-2009)
ext2fs_check_if_mount: No such file or directory while determining whether /dev/mmcblk0p1 is mounted.
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
63872 inodes, 255198 blocks
12759 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=264241152
8 block groups
32768 blocks per group, 32768 fragments per group
7984 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376
badblocks: not found
Writing inode tables: done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
root:/dev> mke2fs -j -c /dev/mmcblk0p2

Creating journal (4096 blocks): mke2fs: No such file or directory
while trying to create journal
root:/dev>
I can't format to ext3 filesystem.
In the kernel I enable the ext3 filesystem, fdisk, e2fsck and mke2fs
Can somebody help me
Thanks.

Thanks Andrew
I use this comand: "ln -s /proc/mounts /etc/mtab"
Now is working. Thanks for help
I had one question.
Why the format in ext2 was working fine and the format to ext3 need this symlink?
Thanks

I don't know why format in ext2 working without that. I found that solution when faced with this problem month ago.
