Re: [Ltib] Way to calculate uncompressed image size..

[Erik Peterson]

Hi,

After building your image, you should see the sizes listed for example  
( otherwise, I am not sure you want to use df on your host ):

WARN: /auto/freescale/ltib/ltib-mpc8544ds-20071122/rootfs.tmp/sbin/ 
ldconfig statically linked

Filesystem stats, including padding:

    Total size            = 343396k
    Total number of files = 13263

Your ramdisk exceeds the old default size of 4096k, you may need to
set the command line argument for ramdisk_size in your bootloader
allowing 10% free this gives 377735k .  For instance, for u-boot:


setenv bootargs root=/dev/ram rw ramdisk_size=377735

creating an ext2 compressed filesystem image: rootfs.ext2.gz
creating a uboot ramdisk image: rootfs.ext2.gz.uboot
Image Name:   uboot ext2 ramdisk rootfs
Created:      Fri Mar 14 11:57:51 2008
Image Type:   PowerPC Linux RAMDisk Image (gzip compressed)
Data Size:    111426142 Bytes = 108814.59 kB = 106.26 MB
Load Address: 0x00000000
Entry Point:  0x00000000

Build Succeeded
