[microblaze-uclinux] u-Boot image not execute?



Dear all,

I have downloaded the U-Boot srec image to my board.
However, the execution of U-boot is not triggered, instead the following messages occur:

=================================================
FS-BOOT First Stage Bootloader (c) 2006 PetaLogix
=================================================
FS-BOOT: System initialisation completed.
FS-BOOT: No existing image in FLASH.  Starting image download.
FS-BOOT: Waiting for SREC image....
FS-BOOT: Image download successful.
FS-BOOT: Warning image location differ from default boot location. Image will not boot automatically after POR.
FS-BOOT: Press 'n' to boot old image.
FS-BOOT: Use new image.
FS-BOOT: Booting image...
0x26FFC000 --> the starting address of u-boot

I have checked the code.

Go(image_start) points to the starting address of SDRAM which I download the u-boot.srec.

So what's the problem?

Please advice. Thanks.
