[U-Boot] Problem booting linux with device tree table

Hi all

I am trying to boot mpc8313erdb with linux-2.6.35.4, i am using the last verion of u-boot from denx

i use dtc compiler with following command: dtc -R 8 -b 0 -O dtb -I dts -S 0x3000 -o my.dtb my.dts

Booting process gives following error and reset the board. WARNING: could not create /chosen FDT_ERR_NOSPACE. ERROR: /chosen node create failed - must RESET the board to recover.

somebody advises me to add a chosen node in my DTS file，but The issue is not solved.

Regards.
