[U-Boot-Users] size of mips U-boot image

[U-Boot-Users] size of mips U-boot image

[C Michael Sundius]

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.

[U-Boot-Users] linking u-boot for mips little endian w/ hardhat tools.

[C Michael Sundius]

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:

[Charles Eidsness]

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
@@ -21,4 +21,4 @@
  # 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?

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,

Wolfgang Denk

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.
