Hi,everyone.I have a DE3 board(EP3SL150F1152C).I want to transplant uClinux to the board.I do followed the www.nioswiki.com (http://www.nioswiki.com). I use the DE3_demonstrations in the DE3_v.2.2_CDROM which is in the disk.But when I do the step 'nios2-termianl'.it is shown as followed:

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>

then show nothing.

I do not konw why can not run uclinux.

Is there anyone transplant uClinux to the DE3 board? If you transplanted uClinux to the DE3(EP3SL150F1152C).Could you give me the file ***.ptf and ***.sof of your project.Thank you very mucn!

Hi

I just search for this solution as well just now.

Before this i have ported uclinux on the stratix II developement board.

I took the DE3_150_DDR2_1G_1RANK reference design from the de3 system design cd and try port uclinux on that system. First problem i encounter is that the nios2-terminal hang after this display on the terminal:

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

nios2-terminal: "USB-Blaster [USB 4-1.2]", device 1, instance 0

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

Then i checked the system design again and found that the cpu reset vector and Exception vector are on onchip_mem

Then I disable the onchip_mem and connect the cpu instruction master and data master to the altmemddr which is the high performance DDR2 SDRAM. Then i reconfigure the cpu reset vector and exception vector to altmemddr, regenerate and recompile the design.

After all the configuration, the uClinux amazingly boots up. :D

hope this helps.

How do you configure the kernel?

oh ya, I default all the kernel configuration.

It usually enough to get uClinux to boot up.

Now I'm still working on the ISP 1761 drivers for DE3 dev board.
