difference between bzImage and vmlinux

jsjcaowei · 12-02-2009, 01:46 AM

I am learning Uboot end RedBoot!
In the makefile I find bzImage and vmlinux。
So now, I know vmlinux maybe linux kernel!
Is bzImage an compressed image of vmlinux?
So I speculate that :
1) bzImage is an compressed image of vmlinux ;
2) bzImage finally will be built to Redboot/U-boot.
But in the makefile I find :

(1)In \arch\arm\boot\Makefile:

$(obj)/zImage： $(obj)/compressed/vmlinux FORCE

(2)In \arch\arm\Makefile:

# Convert bzImage to zImage
bzImage: zImage

I am so confused.

Hi,

Would this clear things up a bit?

vmlinux - Wiki

Hope this helps.
