[Adeos-main] building user space xenomai 2.5.6 for ARM

[Adeos-main] building user space xenomai 2.5.6 for ARM

[AKS]

Hi Gilles and other mates

Good day! I would like to ask your help in building user space xenomai.

I have patched Adeos-ipipe-2.6.35.9-arm-1.18-01.patch to omap 2.6.35
so that it will work with Xenomai 2.5.6. I have managed to compile the
I-piped patched Linux kernel and let the Xenomai running - I have tested
on the Linux by dmesg | grep -i I-pipe and dmesg | grep -i Xenomai. And
I can ./configure the Xenomai by

./configure --enable-arm-mach=omap3 --enable-arm-arch=armv7l as the
kernel returns armv7l when uname -i. But I cannot sudo make install it
by native compiling on my target machine. On my host machine which
is running Ubuntu 10.10, I can make (after ./configure as stated above)
and make install.

But on my target box running omap3 processor with armv7l core - I am
using Gumstix - I cannot make or make install.

It exits with error 1, giving me the message as follows

{standard input}: Assembler messages:
{standard input}:47: Error: invalid swi expression
{standard input}:47: Error: value of 10420290 too large

xxxxx

Then return with Error 1. I am using Ubuntu/Linaro gcc compiler for ARM
gcc 4.5.2 and I will be glad if anyone can share experience to fix this issue.
Cheers!

You do not need enable-arm-arch, all omap3 have the same architecture,
so configure takes care of this.

You are probably compiling for the thumb or thumb2 instruction set. We
do not support thumb. Compile for ARM. You should also enable EABI.

Hi Gilles

Thanks and how to configure so that thumb will not be included.

I checked ./configure --help | grep -i thumb

But I did not see any hint how to omit thum2.

I can native compile kernel, drivers and user space applications on
target. But xenomai client is an issue. Please advise. Thanks!

I never had this issue, so, I do not know how to get a toolchain
compiling for thumb by default to compile for the arm instruction set.
What you can do, however, is to use a different toolchain.

See crosstool-ng is you want to build your own. Or use one which does
not compile for thumb. Codesourcery for instance, or a linux distribution.

In any case, the Xenomai or Adeos mailing lists are not the best place
to get an answer to such question.
