kernel image in SDRAM but not booting?

Hi jigdo,

First ... what version of u-boot are you using, and where did you get it from?

How did you do this? You must use the bootm command to correctly boot a kernel.

What does this mean? Please provide some details -- it is difficult for us to guess what you

are observing ;-)

The _variable_ "kernel" is a function pointer ... it points to the entry point of the kernel. When

you create a u-boot kernel image with mkimage, you specify this address with the -e option.

Please provide more details ... what address did you specify? ... what is at the address

that you specify? What are you trying to do?
