[uClinux-dev] FAT32 USB doesn't work

[Claudia De Bartolomeis]

Hi everybody,
I'm developing an application under uclinux  uclibc 0.9.26 for Coldfire 
m532x.

If I try to mount a FAT32 USB stick

--->  as a vfat fs:

    # mount -t vfat  /dev/sda1 /mnt/floppy/
    mount: Mounting /dev/sda1 on /mnt/floppy failed: No such device or 
address

it doesn't work!!

--->  as a msdos fs:
  # mount -t msdos  /dev/sda1 /mnt/floppy/

It works and I can read its content,
but when I write something and I try to unmuont, I get the following:

# cp HmiErrors.log  /mnt/floppy/
# umount /dev/sda1
