What is wrong with uClinux boot?

I have solved my problem.

It is because of the Flash Programming Design.

But another problem comes.

When I make the system with Nios II/s Core + SDRAM + SRAM + Flash + EPCS + Timer + PIO + JTAG-UART, I creat the kernel and filesystem, upload them. The uClinux can startup in the Nios II SDK Shell.

When I add the OpenCores 10/100M MAC, reconfigure the kernel with the igor_mac support, rebuild the kernle and filesystem. Upload correctly.

But when type nios2-terminal in the Nios II SDK Shell console, the screen display

"

nios2-terminal: ....................................

nios2-terminal: starting in terminal mode (Control-C exits)"

The cursor stay here, nothing appears in the screen. I do not know what is wrong. But without igor_mac, the system can run uClinux properly.

I use Microtronix Cyclone Development Board.

The OpenCores 10/100M Mac is the earliest version of Microtronix Provided(run under nios I and uClinux V1.0 with linux 2.4.17 kernel).

Can guys help me? If it is because of the old Version of igor_mac, can someone give me the latest version of the igor_MAC? Just Paste here.

Thank you very much.

In addtion, If I use Custom Board, in uClinux Configure Kernel,

Processor type and feature --> Platform , which platform shoud I use?

Thank you.
