Could anyone give me an approximate size of the U-boot 
image for a mips system when configured with a reasonable configuration:
i.e. with jffs2 support and support for bootp/tftp?

I realize the size can vary depending upon what stuff you pack in there, 
but I'm just looking for a general size.. since if its in the ball park I can 
do the tailoring to make it fit in our FLASH... If not, I'll have to do more 
thinking :]

thanks

So far, all images I've seen fit easily in 256 kB. You will  have  to
omit a lot of "nice to have" stuff to squeeze U-Boot into 128 kB.

Hi,

I am trying to port u-boot to a system w/ a mips 4kc little endian processor.

in looking at other cpu/boards to use as a starting point/template, I chose 
the tb0229 board as it looked to also be a 4kc little endian cpu.

when I build, I get the an undefined reference to _GLOBAL_OFFSET_TABLE_.

I did some fiddling aroud, and comparing to linker command files for other 
boards and I found that the line:

	OUTPUT_FORMAT("elf32-tradlittlemips", "elf32-tradlittlemips",\ 
				"elf32-tradlittlemips")

if changed to:

	OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips")

will allow me to compile and link fine...

my question is then:

1) what does this really do?
2) if I'm using a little endian cpu, do I really need it set to 
elf32-tradlittlemips?
3) if so how do I solve my problem?
4) if not why?

one more note the compiler/toolchain that I'm using is from montavista, the -v 
option displays the following:

Hi Mike,

If you change the file format to tradlittlemips then you'll also need to 
compile using the little endian flag (-EL) instead of the default big 
endian flag (-EB) flag. If you haven't already you'll probably have to 
do something like this:

--- cpu/mips/config.mk	2003-06-27 17:32:33.000000000 -0400
+++ cpu/mips/config.mk	2004-10-04 16:09:31.612045528 -0400

  # MA 02111-1307 USA
  #

-PLATFORM_CPPFLAGS += -mcpu=4kc -EB -mabicalls
+PLATFORM_CPPFLAGS += -mcpu=4kc -EL -mabicalls

Hope that helps,
Charles

Maybe it changes the output format from little endian to big endian?

Depending on your toolchain, yes.

Use different tools?

Why what?

The attached file is a patch to comiple and link for tb0229
using MIPS technologies SDE.

I'm sorry, but I have to reject this patch as it breaks  support  for
all  other  existing  MIPS  boards. Please resubmit a new patch which
modifies  compile  and  linker  options  in  a  board  (or  at  least
configuration) dependent way.

Best regards,

I understand your meanings.
There is no need to add to CVS.
This is a only reference to compile U-BOOT for tb0229
and other MIPS little endian board.
