uClinux Unhandled exception #0 in kernel mode @web_server example

[Altera_Forum]

Hello. 

I used Cyclone III web_server example to launch uClinux on my Cyclone III start kit. The reference sof & zImage works fine and I can see the uClinux logo. But when I compile zImage by myself with dts extrated from reference sopcinfo and download to the starter kit, I got below error. I am new to uClinux & niosII and could not find any clue for several days. Would you please help me? sopcinfo, dts and configuration files are attached. Best regards, =================== $ nios2-download -g images/zImage Using cable "USB-Blaster [8-2]", device 1, instance 0x00 Pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 4049KB in 81.8s (49.4KB/s) Verified OK  Starting processor at address 0xC1000000   uClinux-dist$ nios2-terminal nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [8-2]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) Linux version 3.5.0-rc4-01329-ga227997 (julycat@july-sie) (gcc version 4.1.2)# 80 Thu Sep 20 16:58:00 CST 2012 bootconsole [early0] enabled early_console initialized at 0xe8002000 On node 0 totalpages: 8192 free_area_init_node: node 0, pgdat c0576104, node_mem_map c058c960 DMA zone: 64 pages used for memmap DMA zone: 0 pages reserved DMA zone: 8128 pages, LIFO batch:0 pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 pcpu-alloc: [0] 0  Built 1 zonelists in Zone order, mobility grouping on.
