[oe] Error in building OE for MicroBlaze!

[Ali Akbar Zarezadeh]

Hi Again,

Since last week I changed my way to use the existing MicroBlaze  
toolchain provided by Xilinx (http://xilinx.wikidot.com/mb-gnu-tools)  
as an external toolchain in OE. Therefore, I modified my local.conf  
like this:

TARGET_VENDOR = "-none"
TOOLCHAIN_TYPE = "external"
TOOLCHAIN_BRAND = "csl"

MACHINE = "xilinx-ml605"
TARGET_ARCH = "microblaze"
TARGET_CPU = "microblaze"
TARGET_TUNE = "microblaze"
# Hardware project options
XILINX_BSP_PATH =  
"/home/akzare/Projects/PICSY/Hardware/SoC/EDK/virtex6/Segmentation/microblaze_0/libsrc/device-tree_v0_00_x"
XILINX_BOARD = "ml605"

I copied the Xilinx toolchain in this location:

/opt/local/LinuxKernel_mb/Tools_MB_BE/microblaze-unknown-linux-gnu/bin

and then:

export  
PATH=$PATH:/opt/local/LinuxKernel_mb/Tools_MB_BE/microblaze-unknown-linux-gnu/bin

And for distribution I use the minimal.conf + these lines:

#Machine specific tweaks, will move to its own include soon
PREFERRED_PROVIDER_virtual/kernel = "linux-xilinx-ml605"
PREFERRED_VERSION_linux-xilinx-ml605 = "2.6.37"

I try to simply do: bitbake helloworld-image

This mechanism is successful up to 266'th task.

Now, I stop by this error:

Is there any suggestion?
