how to download u-boot to the NEEK

Hi any! !

Could you please tell me why U-boot does not work on NEEK?

When I downloaded following file and compile it(nios2-linux-20090929.tar),I got the following error message.

We excuted NIOSⅡ 9.0 Command Shell on Windows with following procedures.

Connecting NEEK and PC via USB cable bundled NEEK.

Step1) u-boot compile.

linux$ cd nios-linux/u-boot

linux$ make clean

linux$ make NEEK_C3_config

linux$ make

Step2) sof-file donwload.

(Using the neek_ocm_spi_mmu.zip "sof-file".)

[NiosII EDS]$ nios2-configure-sof cycloneIII_embedded_evaluation_kit_standard.sof

Step3) u-boot donwload.

[NiosII EDS]$ nios2-download -g u-boot

Step4) Execute.

[NiosII EDS]$ nios2-terminal.exe

The error message is follows.

The combination of following U-boot and the neek_ocm_spi_mmu.zip

"CycloneIII_embedded_evaluation_kit_standard.sof" worked correctly.

I tried to fix it refer to above error message, but I couldn't .

Could you please tell me I'm getting this error?

Can you tell me how can I fix it?
