[U-Boot-Users] crosstool for PowerPc 8540

[Junita Ajith]

Hi
 Could anyone suggest me the toolchain to be used to
compile u-boot-1.1.1 for a PowerPC 8540 board?

  I tried with the crosstool-0.27 (www.kegel.com)
which is supposed to be the stable version ,and built
a toolchain with gcc-3.3.2 and glibc-2.3.2.

  I could successfully build my toolchain and create
my u-boot binary for 8540.
   
   But when I flash u-boot.bin , the board doesnt come
up.
       
Any help would be appreciated.

Thanks,
Junita

You can for example use ELDK release 3.1

What makes you think that thgis is  a toolchain issue?

Attach your BDI2000 and start debugging.

I've used various versions, 2.95, 3.2, 3.3, 3.4.{2,3}, etc.
Make sure your binutils is 2.14, etc.

OK, this is good...  Have you verified that it looks sane?
Is it the right size, have a good header and layout, etc?
You might use objdump or od to verify these things too.

Darn good question!

Say, any chance you read through doc/README.mpc85xxads?
Or maybe doc/README.sbc8560, or looked at include/configs
for the right board?

Hmm.  So which board is it, actually?  Is it a custom board?

   I  did download ELDK and ran install. As the
dcoment says , by default it installs all the
supported architectures , and so it did for ppc-8xx,
ppc-4xx etc.But I didnt see ppc-85xx.

   So I tried specifying the architecture.This is what
I got. 


[root at new-host iso]# ./install -d /opt/tools/ELDK/
ppc_85xx
 
 
Do you really want to install into /opt/tools/ELDK
directory[y/n]?: y
 
Installing cross RPMs
 
Done
 
the ppc_85xx target does not exist in . directory
the following targets are available:
ppc_4xx
ppc_4xxFP
ppc_6xx
ppc_74xx
ppc_8xx

  Am I missing something ? Because even in the ftp
sites under supported architectures for release-3.1 ,
ppc_85xx is not mentioned .
 
   I am sorry if the mail is not appropriate for this
mailing list.

Thanks ,
Junita

Why are you quoting the same text twice?

There is no need to make a complete set  of  packages  for  each  and
every family of processors.

Right. And as you may have notived, there are some  symlinks  created
(like ppc_82xx) which pount to the ppc_6xx sub-tree. 

> ppc_85xx is not mentioned .

No, and some other architetures  (like  MPC52xx)  are  not  mentioned
either.  But  the tools in the ppc_6xx packages support all of these.
Just set CROSS_COMPILE=ppc_82xx- and use  the  asppropriate  compiler
flags.

[U-Boot-Users] Help needed to compile u-boot-1.1.1 for 8540 with ELDK-3.1

[Junita Ajith]

Hi all,
   I've installed ELDK-3.1 and compiled my
u-boot-1.1.1 for PowerPC - 8540, setting
CROSS_COMPILE=ppc_82xx- . and compiled it for e-500.

   I didnt see the serial output until I changed the
cpu/mpc85xx/config.mk . 

I added -mabi=no-spe, (as its recommened by Motorola
for 8540/8560) in PLATFORM_RELFLAGS and   -mno-string
for PLATFORM_CPPFLAGS.

  Now I could see the serial output and it hangs where
the code uses 'sprintf' .
   This happens only with ELDK-3.1 but also with a
toolchain built with gcc-3.3.2 & binutils -2.14.

  I dont think its a board problem , as I eliminated
the sprintf , the problem is solved at that point and
then it hangs at another point where  'sprintf' is
used.

I did step through BDI2000 and it crashes at that
place.

  Do I need to change the compiler flags ..or am I
going wrong somewhere.

   Any help would be appreciated as it would save a
lot of my time .

Thanks
Junita

Which 8540 board do you have?  And is that really the
official 1.1.1 release?  If so, that is old.  A lot old.
Grab the top of CVS at least.  (It should claim to be
1.1.2 though that is just the development of 1.1.2 and
not a real official release.)

I use these:
    PLATFORM_RELFLAGS += -fPIC -ffixed-r14 -meabi

    PLATFORM_CPPFLAGS += -DCONFIG_MPC85xx -DCONFIG_E500 -ffixed-r2
    -ffixed-r29 -Wa,-me500 -msoft-float

I think there is potentially an issue with the location
of the string used by sprintf().

That's pretty vague... :-)

I'm concerned that you had to change the flags.

I think you should grab the current top of CVS too.

   I am using am 8540 custom board.  As you have
suggested , I did download the latest u-boot-1.1.2
from CVS .With a few changes in the board-specific
config file I was able to successfully compile and
build it with ELDK-3.1 .

  I had to add -mno-string as well to
PLATFORM_CPPFLAGS (in u-boot cpu/85xx/config.mk)

   without that I couldnt see the serial output.


So thanks so much for all the help.

Thanks & Regards
Junita

[Kumar Gala]

It's odd that we are not already doing that, the e500 core in 85xx does 
not implement the string instructions.

[U-Boot-Users] crosstool for PowerPc 8540

[Junita Ajith]

Could someone suggest me the -m switches to cross
compile u-boot-1.1.1 with gcc-3.3.3 for an Power PC
8540 board.

Thanks
Junita

Using the current source tree (i. e. top of  CVS)  with  the  default
options  as  defined  in U-Boot works just fine (tested with ELDK 3.1
and - for example - MPC8540ADS configuration).
