hi maoguohua,

To reduce the size of the kernel, you can re-configure the kernel and disable those features you don&#39;t want. For example, if you don&#39;t want TCP/IP stack, I am sure you can reduce the size of resulting kernel a lot. Some filesytem, device drivers can be configured off. But I&#39;m not sure if you can get a kernel image as small as 500k.

If you don&#39;t have enough flash space to put the kernel, you can try compressing the image, like a Linux desktop. A compressed image can be easily smaller than 500k, but you need some booting code to uncompress the kernel...
