my RAM disk is too big
when I use the command 'df' on the developer board I get the next information:
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/flash3 3168 3168 0 100% /
/dev/flash2 192 32 160 17% /mnt/flash
tmpfs 3472 184 3288 5% /var
As you can see I have more than 3 MB of free space on the RAM disk ( /var ).
Is this memory reserved for the RAM disk, or can it also be used by the CPU?
If it cannot be used by the CPU, how can I free up this memory? I don't need
such a big RAM disk.
