Linux not booting

I have compiled Linux and the yaffs

I did these
[f] Format the nand flash
[x] format NAND FLASH for Linux
[v] Download vivi
Then
[k] Download linux kernel
[y] Download root_yaffs image

When it boots up. It tells wrong kernel

Is there any special format convertion after we get the uImage

Which Linux kernel did you compile? 

Did you actually convert it to a uImage after compilation? I hope not as
you will need u-boot to download the kernel image, not Supervivi.

After compilation you will have a zImage.  You need to take a special step
to convert it to a uImage.

Think it would be best to actually copy and paste the error message.
