Im using buildroot-2009.02 on atmel at91sam9g20ek. It is a fairly stock
When I execute "losetup /dev/loop0 /mnt/flash/backing_file.vfat" i get
the error "losetup /dev/loop0: No such device or address". /mnt/flash
exist and has a mounted jffs2 filesystem on it.As far as I can tell, it
is working correctly. I can read/write files. I have checked all the
obvious suspects (including erroneous error message)
here is the output from mount
rootfs on / type rootfs (rw)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /tmp type tmpfs (rw)
sysfs on /sys type sysfs (rw)
/dev/mtdblock2 on /mnt/flash type jffs2 (rw)
looks like a valid mounted filesystem.
# ls /mnt/flash
the file I am trying to connect to loop0 definately exists. I copied
/etc/hosts to it to verify read/write operation.
here are the /dev/loop* devices
# ls -atl loop*
brw-r----- 1 root root 7, 0 Dec 31 17:00 loop0
brw-r----- 1 root root 7, 1 Dec 31 17:00 loop1
/dev/loop0 definitely exists and appears to be correctly defined (I think).
Anyone aware of issues using losetup? Is there some obscure dependency
I might be missing. any suggestions on how to debug this short of
printf() from losetup code?
