more than one ramdisk

[Rohner Thomas]

Thanks Sebastian,

this was my first contact to users at rtems.org

Yes, I do mount 2 different filesystems (both FAT16)  on a RAM-Disk. Is this allowed?
The binary files are generated by makefile.

@dd if=/dev/zero of=fatbin1 bs=1024 count 2048 > /dev/null 
/sbin/mkfs.vfat -n name1 -i DiskID1 -F 12 -S 512 -s 1 -r 512 -f -v fatbin1
mcopy -b/ -i fatbin1 content/* ::/

@dd if=/dev/zero of=fatbin2 bs=512 count 1024 > /dev/null 
/sbin/mkfs.vfat -n name2 -i DiskID2 -F 12 -S 512 -s 1 -r 512 -f -v fatbin2
mcopy -b/ -i fatbin2 content/* ::/

Should I use some more options?

you cannot mount a RAM disk, you can mount a file system on a RAM disk.  Which file system do you use and which parameters do you use for mount()?

I guess this is because both RAM disks have the same device identifier.
