Hi,Hippo

Thank you for your suggestion. I will post my result here.

I am sorry,I made a mistake.

I use vmlinux as my image, it should be zImage.

I run the command "nios2-download -g zImage ", then in my uart port there is a message

Uncompressing Linux... Ok, booting the kernel.

Then it come to a stop.

My custom board use Cyclone (EP1C6), should I choose the Altera Cyclone board in the "Processor type and features" when menuconfig the kernel?
