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

You can for example use ELDK release 3.1

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

I could successfully build my toolchain and create my u-boot binary for 8540.

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.

But when I flash u-boot.bin , the board doesnt come up.

What makes you think that thgis is a toolchain issue?

Darn good question!

...

Any help would be appreciated.

Attach your BDI2000 and start debugging.

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?

Why are you quoting the same text twice?

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.

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

the ppc_85xx target does not exist in . directory the following targets are available: ppc_4xx ppc_4xxFP ppc_6xx ppc_74xx ppc_8xx

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.

Best regards,

Wolfgang Denk

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.)

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.

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

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

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

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

That's pretty vague... :-)

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

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

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

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

u-boot-1.1.1 for PowerPC - 8540,

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

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

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

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).
