Can not do TryOutuClinux!

Hi,

This days, I am trying to resolve the problem about running the uClinux in Altera Nios dev board, mentioned in my last post, so many methods I've tried, even followed the steps in TryOutuClinux in nioswiki, but there is only one result, failed. here is the information system gives me:

>>Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

>>Pausing target processor: not responding.

>>Resetting and trying again: FAILED

>>Leaving target processor paused

I am so sad with this problem.

I am afraid the dev board is broken, that will be terrible.

Anyone got idea?

    hippo, I also build a memory test project with the standard .ptf file, and it runs in IDE. This project can test flash, sram and sdram in dev board.

    type, begin address , end address, size

    flash 0x00000000 , 0x008FFFFF, 8M

    sram 0x02000000, 0x020FFFFF, 1M

    sdram 0x01000000, 0x01FFFFFF, 16M

    The flash and sram are OK, but when I test the sdram, nothing responsing. The following is the information in console. 

    nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster ", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

    No result about sdram! I tries many times and got the same thing.
