boot uClinux kernel problem

Hi~ 

Could you help me, thanks. 

 

The kernel image and .sof is OK. 

 

Then, when I try to download them to DE0 board 

 

I key in command 

 

"$nios2-configure-sof DE0_TOP.sof" and "$nios2-download -g zImage" 

 

They are OK. 

 

But when I key in command 

"$nios2-terminal" 

 

It stuck at "PID hash table entries: 32 (order: 5, 128 bytes)" 

It can not continue to execute  

************************************************ 

[NiosII EDS]$ nios2-terminal 

nios2-terminal: connected to hardware target using JTAG UART on cable 

nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) 

Uncompressing Linux... Ok, booting the kernel. 

Linux version 2.6.19-uc1 (root@ubuntu) (gcc version 3.4.6)# 27 PREEMPT Mon Jul 2

This looks like a very old kernel version. Where did you get/build that from? Please follow the instructions from the Altera Wiki (http://www.alterawiki.com/wiki/linux) to get a more recent version of the Kernel and uClinux-dist
