dumpimage: fit: extract FIT images
The dumpimage is able to extract components contained in a FIT image:
$ ./dumpimage -T flat_dt -i CONTAINER.ITB -p INDEX FILE
The CONTAINER.ITB is a regular FIT container file. The INDEX is the poisition
of the sub-image to be retrieved, and FILE is the file (path+name) to save the
extracted sub-image.
For example, given the following kernel.its to build a kernel.itb:
/dts-v1/;
/ {
...
images {
kernel@1 {
description = "Kernel 2.6.32-34";
data = /incbin/("/boot/vmlinuz-2.6.32-34-generic");
type = "kernel";
arch = "ppc";
os = "linux";
compression = "gzip";
load = <00000000>;
entry = <00000000>;
hash@1 {
algo = "md5";
};
};
...
};
...
};
The dumpimage can extract the 'kernel@1' node through the following command:
$ ./dumpimage -T flat_dt -i kernel.itb -p 0 kernel
Extracted:
Image 0 (kernel@1)
Description: Kernel 2.6.32-34
Created: Wed Oct 22 15:50:26 2014
Type: Kernel Image
Compression: gzip compressed
Data Size: 4040128 Bytes = 3945.44 kB = 3.85 MB
Architecture: PowerPC
OS: Linux
Load Address: 0x00000000
Entry Point: 0x00000000
Hash algo: md5
Hash value: 22352ad39bdc03e2e50f9cc28c1c3652
Which results in the file 'kernel' being exactly the same as '/boot/vmlinuz-2.6.32-34-generic'.
