help: i got a core dumped while building u-boot-2011.06 use eldk5.0 for armv4t.

hi, all

i got a core dumped while building u-boot-2011.06 for s3c2440a chip 

which is arch v4t use eldk5.0 with USE_PRIVATE_LIBGCC=yes.

building is ok without USE_PRIVATE_LIBGCC=yes but only got a v5t 

elf u-boot file.

my building is on centos 6.0, all env variable setting is done as following:

export PREFIX=/opt/eldk-5.0/armv5te/sysroots/i686-oesdk-linux/usr/bin

export TARGET=arm-linux-gnueabi

export PATH=$PREFIX/armv5te-linux-gnueabi:$PATH

export CROSS_COMPILE=${TARGET}-

building command is following by denx faq ��GCC generates illegal opcodes
for ARMv4T systems��

make distclean

USE_PRIVATE_LIBGCC=yes make AS2440_config

USE_PRIVATE_LIBGCC=yes make

                            here is my building error message:

ELDK-5.0 supports armv7 and armv5t - I do not know if someone else
except you tested with v4t...

I known eldk-5.0 supports v7 and v5t, I see a denx faq which said can
do this with pre-setting USE_PRIVATE_LIBGCC=yes, I do it, then core dumped
happened.
that faq link is:
http://www.denx.de/wiki/view/ELDK-5/QuestionsAndAnswers#GCC_generates_illega
l_opcodes_fo

maybe I can try a older version of eldk, I'd like to try eldk-5.0 firstly, 
I'v downloaded and installed 5.0 already and it work well under my test.

I think eldk-5.0 maybe backward compatible before.

Thanks for your reply.

Best regards,
liujun

This is a pretty clear error message, isn't it?

It appears that the divide operation in the YAFFS2 code requires a GCC
helper function which is not yet provided in the mainline U-Boot code.

Please feel free to submit a patch to add it.

Unfortunately you are referring to out-of-tree code here.  We cannot
test this build, so we cannot help you any further.

Best regards,

Dear "Denk",
I've downloaded an older version eldk x86-linux iso installation file and
installed it on centos6, it's eldk4.2, nowtime work fine in making
u-boot-2001.06 for armv4t, no undefined reference to __aeabi_uldivmod error
message and no core dumped.
down u-boot.bin to armv4t(S3C2440A, arm920t) board, start up ok.

thanks.

Becuase ELDK 4.2 was build for armv4t, its libgcc will have a suitable
uldivmod for your usecase, so that was actually expected.  Still it is
working around the problem that Wolfgang clearly describes:

So we would still be thankful if you would fix this real problem so
other people will also benefit in the future from the free help that you
got.

Thanks

Issues building ELDK-4.2 from scratch

Hi,

I'm building ELDK-4.2 for ppc_4xx from scratch. I'm following the document
http://www.denx.de/wiki/DULG/ELDK .

I created a VM with Fedora core 5; server installation.

I got the eldk sources via git; url:  git://git.denx.de/eldk-4/{build,tarbals,SRPMS}.git

I'm getting  several errors. By modifying the files listed below I reached the package wpa_supplicant. I
got a MD5 sum (listed  below)  when installing the src rpm.

So, am I using the right source code ?  Is there any other build tools required in the FC-5 builder ?

May I ask (just out of curiosity) why you are still using ELDK 4.2?
We're working on the 5.1 release now, so I really wonder why you are
stuck with 4 year old stuff?

> I created a VM with Fedora core 5; server installation.

This will most probably not work.

If you really are stuck with 4.2, then please see the detailled
instructions in this application note:

ELDK5.0 for powerPC

Hi,

In ELDK5.0 documentation page 1 -Supported Target Architectures, you
mentioned "Generic PowerPC target for FPU-less systems like MPC8308
etc". But MPC8308 does have a FPU.

I am going to use the MPC8309. It also have a FPU like MPC8308. My
question is: Should I use "powerpc" or "powerpc-softfloat" package?

Thanks,

Herman
