Memory problem

Marta

Hi,

I am using a custom board with dm355 and I have some questions about RAM memory.

Booting my board from NFS and using the "free" command I get:

# free
                    total         used         free       shared      buffers
Mem:        77940        34864        43076            0           20
Swap:            0            0            0
Total:        77940        34864        43076

But booting from NAND flash(uImage and ramdisk), I get:

# free
            total         used         free       shared      buffers
Mem:        77940        64008        13932            0        31764
Swap:            0            0            0
Total:        77940        64008        13932

Can anyone please tell why there are 30MB of difference between them? My ramdisk.gz is 11MB.

Can I do anything to free that memory? I really need that memory free.

Hope anyone can help me.

Thanks!

I have not done too much work with RAM disks but the first thing that comes to mind would be to see if your RAM disk is really taking up 30MB of space, you say ramdisk.gz is 11MB but that is the compressed version, I believe in the process of mounting the RAM disk image that the image is decompressed so though it takes 11MB in storage it may take much more when expanded into RAM.

Thanks for your answer, you were right.
That's my unpacked ramdisk's size.
