the question of the starting of uclinux by u-boot

1

i make an experiment about using the u-boot to startup the uclinux by the your said method that folloes as:

For u-boot

$ nios2-elf-strip u-boot

$ nios2-elf-objdump -h u-boot

For kernel:

$ nios2-elf-strip vmlinux

$ nios2-elf-objdump -h vmlinux

and then download to NOR flash.

but, the question is the same to the before question:

the cursor winding in the windows and my developing board's led is not winding(maybe die).

2 "Another question: are you using a data cache?"

my nios2 is the nios/e(no instruction cache and no data cache).
