Why linux did not boot?

[Altera_Forum]

Hi all, 

After I "make linux image" in red hat linux,I download the zImage to the ram of my custom board with the command "nios2-download zImage" in the Nios2 Command Shell. When I run "nios2-terminal" in the Nios2 Command Shell, the linux did not boot,why? Please tell me how to do?
