Failed to launch barebox from flash memory on i.MX35

[Peter <sailingsmoky@googlemail.com>]

Hi all,
I just managed to compile the latest barebox source (http://barebox.org/download/barebox-2011.10.0.tar.bz2 <http://barebox.org/download/>) for the pcm043 board.
I configured and compiled it:
$ make pcm043_defconfig
$ make xconfig # nothing changed there
$ make

I used the following CROSS environment settings:
export PATH="$PATH:/opt/OSELAS.Toolchain-1.99.3/arm-1136jfs-linux-gnueabi/gcc-4.3.2-glibc-2.8-binutils-2.19-kernel-2.6.27-sanitized/bin"
export ARCH=arm
export CROSS_COMPILE=arm-1136jfs-linux-gnueabi-

The make went well without any problems.
I flashed the barebox.bin at address 0xa000_0000 and rebootet.
The program then trapped while trying to relocate the code to SDRAM.
The SDRAM is propperly initialized but the call to memcpy takes adress
0x9FFFE000 as source and 0x87F00000 as destination.
0x9FFFE000 is definitely not correct, it is 0x2000 below the start of the
flash memory, obviously the same size as symbol  _stext in the map
when subtracting the base address.

Map:
00038e50 A _barebox_image_size
87f02000 T _stext
87f02000 T _text

The source is in arch/arm/copu/start.c at line 122.

I am completly stuck. What went wrong?
Any help will be very much appreciated.

Regards, Peter
