Re: Kernel generates vmImage instead of zImage

Thanks to all but my special thanks go to Robert. I've edited linux-2.6/arch/nios2/Makefile and get it work !

Cheers,

Cem

  the set of buildable targets is typically defined by the
arch-specific makefile.  if you look in the top-level Makefile of the
kernel source tree, you'll see a target for building the generic
"vmlinux" kernel image, but little more.

  you need to dig down into the arch-specific directory to see
additional targets.  for example, if you take a look at
arch/arm/boot/Makefile, you'll see:

targets := Image zImage xipImage bootpImage uImage

ifeq ($(CONFIG_XIP_KERNEL),y)

$(obj)/xipImage: vmlinux FORCE
        $(call if_changed,objcopy)
        @$(kecho) '  Kernel: $@ is ready (physical address:
$(CONFIG_XIP_PHYS_ADDR))'

$(obj)/Image $(obj)/zImage: FORCE
        @echo 'Kernel configured for XIP (CONFIG_XIP_KERNEL=y)'
        @echo 'Only the xipImage target is available in this case'
        @false

else

$(obj)/xipImage: FORCE
        @echo 'Kernel not configured for XIP (CONFIG_XIP_KERNEL!=y)'
        @false
... etc etc ...

  in short, all(?) architectures expect a starting point of a vmlinux,
and they will define additional targets as they see fit.
